Definitions

  • the present invention relates to a method for removing fastener members from a zip fastener tape with a pair of carrier tapes and with helical or meandering fastener members each having a head part, middle part and a base part, which are arranged on adjacent longitudinal edges and coupled to one another, wherein the fastener members uncoupled and aligning the carrier tapes symmetrically with respect to a central plane, arranging a section of the carrier tapes such that their closure members are aligned with the path of a cutting element, the closure members to be removed are positioned with respect to the cutting elements, the sections of the carrier tapes are clamped, the head parts of the closure members to be removed are clamped , cuts through the fastener elements and pulls the fastener elements clamped to the head parts in the direction away from the carrier tapes in order to raise a non-jointed portion old and an apparatus for performing the method.
  • a method and a device of this type are known from EP-A 96 777.
  • the uncoupled closure members are aligned essentially vertically and parallel to a central plane symmetrically, the closure members with the base part the path of a cutting element is aligned and clamped to the head part, the base part is cut in a direction perpendicular and parallel to the central plane, and the cut closure elements clamped to the head parts are pulled off the carrier tape to produce the link-free section.
  • the aim of the invention is to provide a method in which this disadvantage does not occur.
  • the device according to the invention for carrying out the method with a stationary guide block in order to uncouple the closure members and to align the carrier tapes symmetrically with respect to one another with respect to a central plane, with a counter-holder which can be displaced relative to the guide block in order to align the closure members, with a device for the closure members with respect to the cutting element, with a clamping device which is movable relative to the guide block to clamp portions of the carrier tapes, with two gripping elements which are arranged on the counter-holder and are movable relative to the guide block to clamp the head parts of the positioned closure members, and with two cutting elements which are each displaceable relative to the guide block in order to cut through at least a number of the positioned closure members, the counter-holder and the two gripping elements being movable with one another away from the guide block in order to Pulling cut-through closure members from the carrier tapes is characterized in that the guide block has two surfaces which are inclined to one another with respect to the central plane, that the clamping device is an integral clamping member
  • the middle part of a further closure member is additionally cut below the weaving edge.
  • a half number is generated in addition to the link-free section in order to facilitate the threading of a zipper slide.
  • each cutting element is assigned a second cutting element which cuts through the middle part of a further closure element.
  • the device contains a guide block 1, a counter holder 2, a clamping device 3, two gripping elements 4 and at least two cutting elements 5.
  • the zipper tape fed from a roll is separated from a section (not shown) on the guide block 1 and the two carrier tapes 6 with the closure members 7 are arranged symmetrically to a central plane 8 downward.
  • the separation of the zipper tape immediately before entering the device ensures that the gap-to-gap distance is exactly the same length at both closure member identifiers.
  • the conveying device for the zipper belt and the control device interacting with it is not explained in more detail.
  • a shoulder 9 is formed, on which the gripping elements 4 rest with an inwardly projecting gripping section l0, so that an intermediate space is created between the shoulder edge and the gripping section l0, which is used to align the closure members with the web of Cutting elements 5 is used when the counter holder 2 is raised.
  • the closure members 7 point upwards with their base part 11, with their middle part l2 facing away from the carrier tape 7 in the direction of the cutting element 5 and lie with their head part l3 on a shoulder 9 (Fig. 2).
  • closure elements 7 to be removed are positioned precisely with respect to cutting elements 5, so that the end edges of the cutting elements 5 each lie on a gap between two closure elements 7. This is done by optical scanning using a scanning device, not shown, e.g. an optical fiber, i.e. the conveyor for the zipper tape is stopped when this gap is found.
  • a scanning device not shown, e.g. an optical fiber, i.e. the conveyor for the zipper tape is stopped when this gap is found.
  • This determination is considered an on-command for the removal of the closure members 7 described below.
  • the clamping device 3 is displaced from above against the guide block 1 and the carrier tape 6 is clamped at an angle, for example of 45 °, with respect to the central plane 8.
  • the gripper elements 4 are then displaced against the counter-holder 2, as a result of which the gripper sections l0 engage the head part l2 and clamp the closure members 7 to their head part l3.
  • the cutting elements 5 are then displaced in the direction of the central plane 8, as a result of which the central part l3 of the closure members 7 is cut through above the weaving edge 14.
  • the drive of the cutting elements can consist of known elements and is therefore not described.
  • gripping elements 4 are lifted off the counter-holder 2 and the removed closure members 7 by means of a suitable device, e.g. a slide (not shown) pushed out of the device.
  • a suitable device e.g. a slide (not shown) pushed out of the device.
  • the device is then provided again in order to remove the closure members at the next section.
  • the link-free section is delimited by two middle parts l2, which are essentially in the same place, i.e. are cut through above the woven-in edge l4.
  • a half number is provided to facilitate threading the slider onto a zipper tape. This half tooth is produced with a preferred embodiment of the invention, which is described below.
  • a second cutting element 15 is assigned to each cutting element 5. While the first-mentioned cutting element 5 extends over a plurality of closure members, the second cutting element 15 has a cutting edge length which is only sufficient for cutting through a central part 12.
  • the cutting elements 5 and 15 are arranged one above the other in such a way that the closure members 7 are cut through, as shown in FIG.
  • the cutting elements 5 and 15 are guided one below the other and are successively, i.e. first of all the first and then the second cutting element are moved back and forth with respect to the central plane 8 by a suitable drive device.
