    专利说明:

    The invention relates to a device for intermittent application of glue on a moving material, in particular packaging material.
    In packaging machines forming 5 containers from individual preforms, these preforms must be provided with strictly limited adhesive bands. This is done either with the help of a gluing roller, or 10 for applying hot molten gluten by nozzles for applying glue. However, after the glue flow is blocked by closing the nozzle between the nozzle and the adhesive roller applied to the workpiece, for certain types of glue, the threads stretch onto the workpiece and thus create undesirable bonding.
    A device for periodically applying glue is known, in which the nozzle is equipped with a device for periodically blocking it for a period of less than 1/100 s, which should reliably prevent the formation of filaments 25 flj.
    However, such a device is difficult to implement in packaging machines operating at different speeds, since quick closing, on the one hand, can be carried out only mechanically, on the other hand, it must be done synchronously with the machine.
    Closest to the invention is a device for periodically applying glue, comprising a housing with a nozzle for supplying glue, equipped with a device for its periodic overlap and a step recess located behind it
    However, the known device also does not reliably prevent the formation of threads between the applied adhesive strips.
    The aim of the invention is to improve the quality of applying glue and prevent interruptions in work.
    This goal is achieved by the fact that in a device including a housing with a nozzle for supplying glue, equipped with a device for periodically blocking it and a step recess located behind it, a hole is made in the recess of the housing connected to a source of reduced pressure.
    The drawing shows the proposed device.
    The device comprises a housing 1, in which a nozzle 2 for applying glue is placed, connected by means of a valve 3 to a capacity 4 for supplying glue (the nozzle 2 for applying glue is shown as being closed). The housing 1 behind the nozzle 2 has a recess 5, in which a hole 6 is made, which is connected to a source of reduced pressure (not shown) so that the adhesive thread 7 is sucked.
    The device operates as follows.
    A device for intermittent application of glue is placed over moving, in particular, packing material 8. When the valve 3 is open, glue from the container 4 enters the nozzle 2 and is applied to the material 8, after applying the roller 9 of the given dyne, the valve 3 closes the nozzle 2, the formed thread 7 is sucked in the hole 6 connected to a source of reduced pressure. The hole 6 can be connected to a source of reduced pressure either when closing valve 3, or is constant, the latter being a simpler solution and fully operational.
    Using the proposed device eliminates undesirable bonding of blanks in areas without glue.
