Definitions

  • ABSTRACT A method and apparatus for removing interlocking fastener elements from a slide fastener chain at predetermined intervals so as to provide alternate elementfree and element-containing sections, the element-free or space sections being utilized for the assembling on the fastener chain of sliders and end stops. Gripping means are provided in the apparatus for gripping the base portions of interlocking element in each element row and retaining a length of elements in position for removal first of the coupling head portions of the elements. Thereafter, said gripping means are retracted sidewise or outwardly of the fastener chain, taking with them the remaining debris of elements off the chain.
  • FIG.1 T Es E METHOD AND APPARATUS FOR REMOVING INTERLOCKING ELEMENTS FROM SLIDE FASTENER CHAIN BACKGROUND OF THE INVENTION
  • This invention relates to the provision ofa slide fastener stringer which has end portions devoid of interlocking fastener elements, more particularly to a method and apparatus for removing fastener elements at predetermined intervals from a slide fastener chain of substantially endless length thereby providing herein alternate element-containing and element-free sections.
  • the present invention has for its object to provide a novel method for removing a desired length of interlocking fastener elements from a continuous slide fastener chain without any damage to adjacent woven or sewn threads, reinforcing cords or tape web and an apparatus for effectively carrying this method into practlce.
  • a method for removing fastener elements from a slide fastener chain consisting of a pair of stringer tapes carrying thereon uninterrupted rows of continuous fastener elements in interlocked relation each of which elements having a coupling head and a base portion merging into adjoining element, which method comprises the steps of positioning a length of interlocked elements with their coupling heads registered with the path of a cutting means; gripping the base portions of said elements in each row to restrict free movement thereof; severing the interengaged coupling heads; and pulling said base portions while being gripped, outwardly apart from their respective stringer tapes to remove the remaining debris of elements thereby leaving thereat an element-free section.
  • FIG. 1 there is shown a segment of a slide fastener chain F which consists of a pair of opposed stringer tapes T carrying along their respective inner edges a row of interlocking fastener elements E. More specifically, the fastener chain F is provided with a predetermined length L of an element-free or space sections alternating with an element-containing section Es. This element-free section is utilized for the assembling of a slider and end stops (top and bottom stops) on the fastener chain F in the known manner.
  • the element removal apparatus generally designated 10 comprises a stationary anvil 11 having a die groove 12 and a vertically reciprocating punch head 13 having a downwardly projecting punch 14 which constitutes with the die grove 12 a coacting die cutter for severing the coupling heads Ea of the fastener elements E.
  • the anvil 11 has seats lla on opposite sides of the die groove 12 for resting thereon the arm portions Ec of the elements as shown.
  • the apparatus 10 further comprises first or male gripper means 15 and second or female gripper means 16 on opposite sides of the anvil 11.
  • the male grippers 15 have gripping jaws 15a formed longitudinally of their respective inner edges and further have downwardly inclined surfaces 15b merging into the jaws 15a.
  • the inclined surfaces 15b are utilized to lift the stringer tapes T thereon away from the rows of elements E so as to permit the gripping jaws 15a to reach and grip the base or connecting portions Eb of the elements E.
  • the female grippers 16 are each provided in the longitudinal edge therof with an elongate recess 16a for receiving the base portions Eb and retaining the same in position during the gripping action of the male gripper means 15.
  • the fastener chain F is positioned on the apparatus with its rows of elements E seated on the anvil l1 and with its stringer tapes T lifted upwardly away from the elementsE as shown in FIG. 2.
  • This is followed by the second operating phase, as shown in FIG.
  • the remaining debris including arm and base portions of the elements E are now removed from the fastener chain F in the fourth or final operating phase wherein the male and female grippers 15, 16 still gripping the base portions Eb begin to retract sidewise away from the anvil 11 taking with them the residual element debris apart from the reinforcing cord 18 and weaving threads 19 which have secured the elements E to the tapes T.
  • the punch 14 will then ascent, leaving a space section such as shown in FIG. 1, which section presents a clean, undamagedelement-free tape portion suitable for smooth assembling of the various fastener parts.
  • a method for removing fastener elements from a rying thereon uninterrupted rows of continuous fastener elements in interlocked relation each of which elements having a couping head and a base portion merging into an adjoining element comprises the steps of positioning a length of interlocked elements with their coupling heads registered with the path of a cutting means; gripping the base portions of said elements in each row to restrict free movement thereof; severing the interengaged coupling heads from the remainder of their respective fastener elements; and moving said gripped base portions laterally away from the line of fastener element engagement to pull free from their respective stringer tapes the remainder of those fastener. elements from which the coupling heads have been severed thereby leaving thereat an element-free section.
  • said punching means for severing the coupling heads of the elements from the remainder thereof, and gripping means operable to grip the base portions of said elements, said gripping means being moveable laterally movement to grip said base portions, and capable of movement in unison while gripping said base portions to pull free from the stringer tapes the remainder of those fastener elements from which the coupling heads have been severed.
