    • 专利摘要:
    Trim strip from a web slitter is received in a chute passageway which guides the trim strip away from the slitter. Low velocity air is supplied in the passageway to provide air lubrication between the chute structure and both opposite faces of the trim strip which thereby floats away from the slitter smoothly and efficiently.

    专利说明:

    the long-cutting machine 3 contains a tray 4, the walls 5 and 6 of which are bent and form a channel 7 for moving the edge 1 from the horizontal plate 8 of the machine. The cut edge 1, along the direction of the crush 9, approaches the winding drum 10 for winding into a roll.
    The cutting machine 3 has a circular knife 11 for slitting the coiled material, working in conjunction with the roller 12. The roller 12 has an electric motor 13 mounted on the frame 14. The tray 4 is also mounted on the frame
    14 and is adjustable relative to vali. ka 12. Tray 4 has side walls
    15 and 16 ..
    Cut edge 1 with deflecting flange 17 and guide plate
    18, forming a neck
    19, is directed to the channel 7. The deflecting rim 17 can be adjusted to change the width of the neck 19. Under the horizontal base 2 O of the tray
    4, a support plate 21 is disposed, carrying the guide sheet 22, which is aligned with the deflecting flange 17. The lower end of the guide sheet 22 is flush with the lower end of the guide sheet 18 and slightly diverges, resulting in an increase the size of the neck 19.
    The means for supplying air to the channel 7 has a row of 23 and 24 located along the movement of the edge 1. The nozzles 23 are located on the wall 5, and the nozzles 24 are on the opposite wall 6.
    The upper nozzle 23 is formed by the lower end of the guide sheet 18 and the plate 25, and the upper nozzle 24 by the lower equestrian guide sheet 22 and the plate 26. The following nozzles, 23 and 24 are formed by the lower ends of the plates 25 and 26, respectively, and adjacent similar plugs 27 and 28. The nozzles 23 and 24 that follow them are formed by the lower edges of the plates 27 and 28 and the adjacent similar plates 29 and 30, respectively. 29 and 31 and respectively 26, 28, O and 32 define a chamber 33 and attached at their upper ends to respective conductive air supply conduits 34 and 35.
    The neck 19, starting from its section between leaves 18 and 22 and down to the lowermost plates 31 and 32, gradually, as it bends down to the vertical section of channel 7, is stretched from the front to the back, thanks to this the gradual volume of air in the air layers in channel 7 as a result of
    The air levitation from the subsequent nozzles 23-24 maintains a uniform and steady displacement in the direction of movement and pressure on the cut edge 1. In addition, it provides a smooth
    5 air flow in these layers. The inner layers of the walls of the tray 4 are equipped with sound-insulating foam 36, the internal dimension of which is protected by perforated metal 37.
    QSopla 23 and 24 can be made slit-like 38 or, as shown in FIG. 5, is a longitudinal row of holes 39 in the wall of conduit 4O. The diameter of each of the openings 39 may be equal to the width of the slit-shaped nozzle 38, and the number of openings 39 must ensure that the same constant volume of air as the slit-shaped nozzles 38 supply. The collector 41 via line 43 communicates with pipeline 35, and the collector 42 via line 44 connects with pipeline 34. Connecting lines 42 and 44 are equipped with control valves 45. Each valve 45. can operate from either an individual or individual actuator, as well as a pairwise action in pipelines 34 and 35 from opposite sides 7. In any case, a smooth movement of the cut edge 1 between the air cushions or lubricating layers, schematically shown, is indicated by the arrows in FIG. 3. The outer walls of the tray 4 are covered with leaded vinyl 46 (Fig. 3).

    Claims (2)
    [1]
    1. An apparatus for removing a cut edge of a web material on a slitting machine, comprising a stream whose walls are bent and form a channel for moving the edge from the horizontal plate of the machine downward, and means for supplying air to the channel having a row mounted on one of the walls of the tray in the course of moving the edge of the nozzles, differently so that, in order to increase the reliability of the removal of the edge, the means for injecting air into the channel additionally has a number of nozzles placed along the course of moving the edge to another counter the false wall of the tray, while the nozzles are made so that their channels are parallel to the corresponding sections of the walls of the tray and are connected to a source of low air pressure. 1,446
    [2]
    2. A device according to claim 1, characterized in that the nozzles are mid; The air supplying facilities are filled with slit-like, the length of which corresponds to the width of the sgenka of the tray. Sources of information taken into account in the examination 1. US Patent No. 3252366, cl. 83-98, 1966.
