    A device for wrapping up the ends of a roll (1) in a wrapping paper (2) by winding the wrapping paper to encircle the roll in a state wherein it extends cylindrically from both ends of the roll, disposing at fixed intervals a set of tucking members (4) at either end of the roll on the outer peripheral surface of the cylindrically extending wrapping paper (2 min ), disposing a set of projecting members (13) at either end of the roll on the inner circumferential surface of the cylindrically extending wrapping paper, simultaneously tucking the tucking members toward the center of the ends of the roll and at the same time gradually puckering up the projecting members to form ridge portions and groove portions on the cylindrically extending wrapping paper, laying flat the ridge portions in one direction and pushing into a central hole (1 min ) of the roll the portions of the wrapping paper which stop up the central hole.

    The iso-peter is related to packaging and packaging technology.
    A device for wrapping cylindrical objects with an axial bore is known, which contains a mechanism for crimping the wrapping material from the ends of the products, consisting of circumferentially radially movable crimping elements, and a pusher for pushing the wrapping material G1 into the opening.
    However, using this device during the crimping of the wrapping material, uneven wrinkles are formed, which leads to a loose wrapping of objects or tearing of the wrapping material.
    The aim of the invention is to ensure the formation of uniform folds during the crimping of the wrapping material.
    The goal is achieved by the fact that the device is provided with stop elements for wrapping material on its inner side, mounted on the pusher shaft circumferentially between the crimping elements and with the possibility of pushing the pusher in the radial direction of the shaft and moving in its axial direction.
    In addition, the crimping elements in cross section have triangular shape.

    FIG. I shows a device for wrapping cylindrical objects with an axial bore, front view with a partial section; and FIG. 2, section A-A in FIG. I; in fig. 3-6 crimping and thrusting elements at various stages of wrapping a cylindrical object; in fig. 7 - a cylindrical object with folded wrapping material before pushing the ends of the clutches into the axial hole, end view; in fig. eight -. crimping element embodiment, front view; in fig. 9 is a view B in FIG. eight; in fig. 0 — view B in FIG. eight; FIG. 11 is a diagram of the formation of folds of the wrapping material. FIGS. 12 and 13 show the interaction of the parts of the crimping element when forming the folds of the wrapping material. The device contains a mechanism for crimping the wrapping material from the ends of the products, which consists of radially movable crimping elements 2 arranged around the circumference of the bearing bar 1. Each element 2 has an axis of rotation 3 and is connected through the lever 4 with a drive, for example, in the form of a hydraulic cylinder 5, The crimping element 2 may have a rod-like or triangular shape in cross section. For pushing the wrapping material into the hole of the product of the bundle of wrapping material, a pusher 6 is arranged disposed on the shaft 7, which can perform rotational and reciprocating movements. A ring 8 is fixed to the shaft 7 and a coupling 9 is movably mounted, the shaft 7 being connected to the actuator 0, and the coupling 9 being connected via a screw 11 to the actuator 12, which gives the coupling a reciprocating movement. In addition, the device is provided with stop elements 13 for the wrapping material on its inner side, which is mounted around the circumference between the first elements 2, with the possibility of folding the pusher in the radial direction of the shaft 7 and moving it in the axial direction, the element 13 through the movable parallelogram formed by the levers 14-17 is connected to the clutch 9, the stop element 13 is rigidly attached to the parallelogram lever 15, the lever 14 is movably connected to the clutch 9, and the lever 17 is connected to the ring 8. All the elements of the device are located on the frame 1 8, which is movably mounted with the help of wheels 19 on rails 20. In the device, the mechanism for crimping the wrapping material may have a different design (FIG. 8-13). The pressing member of this design includes a beam 21 with an edge and rails 22, on which triangular plates 23 are mounted with the possibility of sliding on them, Each plate is 23 connected through bracket 24. With the actuator 25, In addition, the crimping element comprises an elastic rod 26, which can be moved relative to the axis 27 by means of the actuator 28 through the lever 29. The device operates in the following way. The cylindrical object 30 is mounted on the rollers 31, during rotation of which a layer of wrapping material 32 is wrapped around the object, the width of the hanging ends 33 of the tape 32 should be slightly larger than the radius of the end surface of the object 30, Two identical devices are fed to the front parts of the object 30. By moving the coupling 9 along the shaft 7, the stop elements 13 are guided to the inner side of the hanging ends 33 of the wrapping material, to the outside of which the crimping elements 2 are put. The latter are actuated by hydraulic cylinders 5, Then by coordinated movement of the elements 2 and 13 are drooping The ends 33 are guided to the end surface of the cylindrical object 30 (Fig. 3-6), and during this operation, the crimping elements 2 form the depressions of the folds of the curved material, and the thrust elements 13 form the ridges of the folds. At the end of this operation (wrinkling), the thrust elements 13 come out of contact with the wrapping material (Figs 5 and 6) and the crimping elements press the wrapping material formed 1 "And the fold depressions against the end surface of the cylindrical object (Fig. B). Subsequently, the object 309 is rotated, with the result that the ridges of the folds are pressed against the end surface. After that, the ends of the folds are pushed into the axial hole of the cylindrical object by moving the pusher 6. , 12--13) For this purpose, the actuator 25 is turned on, which, through the bracket 24, displaces the triangular plates 23 in a direction towards the center of the axial axis of a cylindrical object, As a result, the recesses of the folds are straightened, and the ridges are compressed between the plates 23 of the adjacent crimping elements (Fig. 1 GZ). After that, the object is rotated in order to press the ridges of the folds to the end surface of the object to be packed. Thus, the device ensures the formation of uniform folds during the crimping of the wrapping material, which contributes to a tighter wrapping of objects and prevents the destruction of the packaging. Claim 1, A device for wrapping qi. axial-hole shaped objects containing a mechanism for crimping the wrapping material from the ends of the articles, consisting of circumferentially radially movable crimping elements. 9 and a pusher for pushing the wrapping material into the hole of the products of the bundle, characterized in that, in order to ensure the formation of uniform folds at. crimping the wrapping material, it supplies} with thrust elements for the wrapping material from the inside, mounted on the pusher shaft around the circumference of the wiper and crimping elements and with the possibility of folding the pusher in the radial direction of the shaft and moving in its axial direction.
