    The feeding of a patterned material web for processing in register with the pattern of the material web is carried out usually by stepwise first feeding of the material web and subsequent fine feeding or register correction. To this end devices for driving, keeping in register and processing of the material web arranged successively are used. A more space-effective method and arrangement for the feeding of a material web (1) is obtained by making use of a web feeding unit (2) for feeding as well as correction of register. The web feeding unit (2) is provided for this purpose with two driving devices (14,15) which during operation are used alternately for feeding and register correction respectively of the material web.

    The invention relates to devices for supplying a marked strip material and can be used, for example, in the manufacture of various packaging containers.
    The purpose of the invention is to simplify the design of the device when the material is supplied with side profiled notches in length.
    Fig, 1 shows the proposed device, side view; Fig. 2 shows a feed unit with a web of material passing through it; Fig, 3 - the feed unit, option; Fig, 4 - the same section; in fig. 5 - the same, option, side view.
    The material web 1, which passes from left to right, is guided through the feed unit 2 to the processing unit 3 for dividing into separate sheets for the workpiece 4. The material web, for example, may be a web of packaging laminate that contains a central carrier paper layer on each Liquid-tight layers of thermoplastic material, such as polyethylene. Such a packaging laminate is used, for example, to make disposable packaging for milk, cream or juice. The laminated web is cut into individual sheets or backstage for the containers, after which it is converted into separate packaging containers filled with contents and sealed, I
    Canvas 1 material passes from
    cumulative bobbin and two drive 40 limiting it on the sides. Each of the rollers (not shown) to the mating flange 16 has two protrusions 15, races 1olica 5, which through the levers 6 is installed with the possibility of rotation in the frame of the machine 7, the Mat roller 5 can swing up and down near the support of the levers 6 in the frame 7 , as indicated by arrow 8, Rolling roller 5 is used to control the rotation of the drive rollers and, therefore, feed the web to the processing unit Q, cutting pieces of material into dimensional workpieces 3 at the desired rhythm. By razking, having two cutting rollers 17 and personal position detectors, the driving rollers are monitored, so that the track roller is always between the two limit positions. The momentary position of the pinnacle is set at opposite ends of the diameter and forms the means for adjusting the position of the web.
    After the web 1 passes the material of the drive unit 2, it reaches the processing unit 3 (FIG. 1), which contains the fixture for
    18, rotating in opposite directions. One of the cutting rollers 17 or 8 is provided with cutting elements 19 in the form of knives diametrically opposed and extending along the central axis of the cutting rollers. Friend oh cutting roller also has located
    ka, thus, continuously changes during the operation of the device and is associated not only with the feeding of the web ia introduced by the driving rollers, but also with the operation of the feeding unit 2, the load on the material web created by the pendulum roller can
    be adjusted to the desired value by adjusting the weight of this roller or, for example, by loading it with a spring.
    After passing through the web of material 5, the roller 5 is guided through a freely rotating guide roller 9 supported in frame 7 on the feeding unit 2. The latter comprises the feeding roller 10 and one or more pressure rollers 11 interacting with its peripheral surface.
    The feed roller 10 can rotate in the frame 7 of the machine, while the pressure rollers 11 are supported on the axis 12 (FIGS. 2 and 5), which can move vertically in the frame 7 of the device some distance above the axis of rotation of the roller 10.
    The rollers 1-1 are driven by a pressure device 13 which allows the mechanical spring or the force cylinder to operate to contact the peripheral
    roller surface 10,
    The latter comprises two driving elements, namely the leading surface 14 for frictional engagement with the web 1 of the material and end protrusions 15 for the formed engagement with the recesses at the edges of the web. The projections 15 are located one against the other on the flanges 16 located on both sides of the surface 14 and
    bordering it on the sides. Each flange 16 has two protrusions 15, material cuts into dimensional workpieces having two cutting rollers 17 and
    placed at opposite ends of the diameter and forming a means for adjusting the position of the web.
    After the web 1 passes the material of the drive unit 2, it reaches the processing unit 3 (FIG. 1), which contains the fixture for
    0 limiting it on the sides. Each flange 16 has two protrusions 15, the length of the Q-pieces of material on the dimensional workpiece, having two cutting rollers 17 and
    18, rotating in opposite directions. One of the cutting rollers 17 or 8 is provided with cutting elements 19 in the form of knives diametrically opposed and extending along the central axis of the cutting rollers. Friend oh cutting roller also has located
    diametrically opposite cutting elements 19 in the form of protruding tools that have a flat working surface with a wear coating, for example plastic. The cutting elements 19 of the two rollers 17 and 18 interact with one another, so that when two rollers rotate simultaneously, they cut the web of material 1 with transverse cuts, dividing it into separate sheets. The two cutting rollers 17 and 18 move synchronously one relative to the other and relative to the roller 10 from the drive.
    The material, divided into separate sheets or blanks 4 for packaging containers, passes through one or more guide rollers 9, located after the processing unit 3, into the gap between the two driving rollers 20 and 21, which during operation of the device rotate with a higher speeds than the cutting rollers 18. The workpiece 4 is thus removed from the processing unit 3 at an increased speed, preventing the separated workpiece 4 from contacting the front edge of the next fabric 1 material and preventing it from cutting in The processing unit 3. The drive rollers 20 and 21 feed individual sheets to a hopper or conveyor (not shown), after which the sheets are transferred manually or automatically to a packaging machine to form packaging containers.
    During the feeding of the web 1 material through the device, it is guaranteed that the web is cut into separate sheets or blanks 4 in accordance with the marking on the web. The material web 1 (FIG. 2) that is being machined has transverse fold lines 22 and recesses 23 located on the two longitudinal edges of the material. The notches 23 are located between the edges 24 and are used to maintain the material web in the correct position during feeding and processing in the processing unit 3. In other types of material webs, other deviations are possible, for example, slots or holes for alignment. For this application, in addition to the projections 15 of the drive roller 10, other means are required for engagement with the web of material.
    The initial web feed that occurs during friction
    the engagement of the web with the surface 14 of the roller 10 exceeds the required value, i.e. the feed distance is longer than the required material length, and the feed correction is achieved by slowing down or pulling back the web until the formative engagement with the protrusions 15 and the web thus does not take the correct position.
    Removing frictional engagement between the continuously rotating cylinder 10 and the material web is carried out (. 4) as a result of the cylindrical driving surface 14 of the roller IO provided with two flat flats 25. When the trajectory of the pressing rollers 11 is limited by the pressing device 13 or some In a different way, the contact between the HO rollers and the pressure rollers ceases when the roller reaches a position in which some of these bald faces 25 face the pressure rollers. In this case, the web can slide relative to the roller, so that a formative engagement between the protrusions and the web is achieved. When this happens, the roller 10 rotates at such an angle that the cylindrical part of the surface 14 enters again under the pressure rollers 11, as a result of which they press the web against the surface 14, so that the friction engagement feeds the web and the edges 24 unlatch. The contact between the edges 24 and the protrusions 15, therefore, exists for a short time and this prevents any deformation of the web on the recesses 23.
    The friction engagement between the web 1 and the surface 14 of the roller 10 may be interrupted in another manner, for example as shown in FIG. 5, where the pressure rollers 1I periodically rise from the roller 10. In this embodiment, there is a cam 26 attached to the roller 10, which cooperates with a follower unit 27 mounted on the axis 12 of the pressure rollers 11. Thanks to such a device that can be duplicated and being at both ends of the roller 10, the axis 12 of the pressing rollers I1 periodically rises from its position on the roller 10, so that the pressure on the material web decreases and it can slide relative to the surface
    14, which in this embodiment may be entirely cylindrical without flat faces 25. Cam 26 may be made as a simple cylindrical roller, on the periphery of which there are j protrusions 28 in places where lifting of the pressure rollers 11 is required, i.e. 90 ° in front of the projections 15 of the roller 10.. This arrangement of bald spots determines that the pinch rollers 11 when turned
    15
    The roller 10 is disconnected from the web 1 of the material immediately before the protrusions 15 enter the corresponding grooves 23 in the web, which provides the maximum time for position correction before the protrusions 15 protrude from the grooves 23 due to the rotation of the roller 10 and the web advancement.
    When the feeding unit is used 20 for webs of material of different widths, the roller 10 is replaced or otherwise adapted to different widths of material, for example at 3030236.
    the engagement between the material and the drive surface 14 of the roller 10. The engagement is guaranteed by the pressure rollers 11, which with the help of the pressing device I3 are pressed against the web I and pressed against the surface 14, so that the advancement occurs without slipping the web relative to the surface 14 at a speed corresponding to the peripheral speed leading surface 14. The latter is approximately 1% longer than the required length of one or more sheets of material, and in the proposed embodiment, its length corresponds to the length of two sheets of mat iala plus 1% in order to meet any deviation from the correct m distance, which may be between the recesses 23 in the material web for correcting the correct position. The roller 10 rotates at a constant peripheral speed, which corresponds to the speed of the cutting rollers 17 and 18. Thanks to a 1% increase in size
    the power to enable flanges 16 to 25 of the periphery of the cylinder
    displace and fix at different distances from one another on the roller 10. The roller requires a driving surface 14 and one flange 16. The latter has no projections 15, and the roller is provided with a row of fingers 29, which are placed in radial holes in the driving surface 14. Fingers 29 are spring-loaded in the direction from the central axis of the roller by means of compression springs 30 with such force that a canvas 1 of material lying on the fingers 29 can press them into the surface, 14 of the roller. At the periphery, the sheet is fed a little further at each feed. This overfeed is somewhat larger than the maximum deviation in the distance between successive
    30 grooves 23 corresponding to the tolerances on the canvas material. These deviations are continuously corrected so that they do not create a cumulative effect that affects the accuracy
     processing unit.
    At each stage of the feed, the web I is first fed with a friction engagement with the surface 14 over a distance that corresponds to the tread of material 1 and the fingers 29 can be kept at a constant feed length, after which they can be extended so that they can. the webs are stopped, and the webs in the longitudinal "o are set in the correct position for subsequent processing by means of the formed engagement between
    edges of the canvas and thus perform the function of the projections 15. This
    The design enables the automatic 45 web material 1 and the feed unit. More specifically, the web feed is interrupted after each movement with the help of surface 14 due to the fact that the contact pressure will consistently adapt the roller 10 to the fabric 1 of material of different widths and can be associated with various variants of the surface of the roller 14 and the work of the pressing rollers I1. Finger protrusions can also be used successfully when the web of material is machined in accordance with the holes provided therein. In this case, the projections must have a smaller extension than the extension of the holes.
    When the device is in operation, the web of material 1 is fed with the help of freaks a little further with each feed. This overfeed is somewhat larger than the maximum deviation in the distance between successive
    30 grooves 23 corresponding to the tolerances on the canvas material. These deviations are continuously corrected so that they do not create a cumulative effect that affects the accuracy
     processing unit.
    At each stage of the feeding, the web I is first fed by friction with the surface 14 over a distance that corresponds to the material web 3 and the feeding unit. More specifically, the web feed is interrupted after each movement by the surface 14 due to the fact that the contact pressure on the surface 50 decreases on the surface 14, which causes the slippage of the web 1 relative to the surface 14. The slippage is caused by the idler roller 5. which descends and increases the distance that the web 1 of the material must pass from the feed cylinders (not shown), moving with constant speed to the feed block 2. In this area the web that passes the feed block 2 slows down the projections 15 do not come into contact with the front edge of the 24 notches 23.
    When this happens and the web 1 is thus locked in the forging engagement with the roller 10, the friction engagement between the web and the surface 14 is again set with the help of pressure rollers 11, after which the web, which is in the correct position relative to the grooves 23, is cut because the rollers 17 and 18 rotate synchronously with the roller 10. In order to allow the slide between the web and the roller, until the projections 15 come into contact with the front edge of the 24 notches 23, it is necessary that the projections 15 notches, i.e. The length of the protrusions 15 in the longitudinal direction of the leading surface 14 must be less than the length of the geometric grooves 23 of the material web that engage the protrusions.
    During the continuous operation of the feeding unit, this procedure is repeated for each processing step, i.e. before each cutting. sheet or workpiece 4 from the canvas. In the proposed embodiment, the roller 10 is provided with two protrusions 15 that are diametrically opposed to one another and the drive surface 14 and must therefore have a periphery greater than the length of the two workpieces 4 by an amount equal to or slightly above the maximum (approximately 1%) plus a tolerance of repeated or fixed length, i.e. the distance between two consecutive notches 23 on the web. In the case of a sheet length of about 300 mm, an overall increase in length of 3 mm, which means that after sheet feeding (rotation by half a turn), roller 10 feeds material by 2-3 mm. The leading edge of the 24 notches 23 is thus somewhat
    ahead of the corresponding front surface of the protrusions 5, which are adjusted before cutting as a result of the frictional engagement between the web and the cylinder being removed, and the web is braked by means of a counter roller to form a shaping engagement between the protrusions and recesses. Due to the alternating action of the two drive elements, the material is periodically corrected with respect to the processing unit, as a result of which the accumulation of length errors is completely prevented and the correct position is maintained for an unlimited time during continuous operation.
