Definitions

  • ABSTRACT A method of assembling sliders to a slide fastener chain is disclosed in which the fastener chain is provided with transverse slits or cuts at spaced locations therealong, which slits or cuts are split open when the fastener chain is deflected downwardly around a cornering point of its path.
  • the slits thus held open have their upper edges registered with a guide channel in a slider to permit the latter to be threaded therethrough.
  • This invention relates to a method of applying sliders to a slide fastener chain of substantially endless length. Attempts have been made to automate the assembly of sliders upon a slide fastener chain which had been mostly by hand, a process which is time-consuming and expensive.
  • Slide fastener sliders are applied to slide fastener tapes by providing spaced confronting slits in the tapes, bending the separated tapes at the slits at a cornering point in a path of intermittent movement, mounting the slider through said slits on said tapes, and advancing the tapes for a length corresponding to the distance to the next slits.
  • FIG. 1 is a plan view of a slide fastener chain prior to theassembly of sliders thereon;
  • FIG. 2 is a perspective view of the slide fastener chain showing the same in a disposition for receiving a slider;
  • FIG. 3 is a plan view of the fastener chain corresponding to FIG. 2 and showing the slider mounted in succession thereon;
  • FIG. 4 is a longitudinal cross-sectional view taken along the line IVIV of FIG. 3;
  • FIG. 5 is a view similar to FIG. 2 but showing a concealed type of fastener to which the principles of the invention can be equally applied;
  • FIG. 6 is a plan view schematically illustrating an apparatus for implementing the invention and showing the disposition of the fastener chain relative to the same;
  • FIG. 7 is a plan view of a slider holder which constitutes part of the apparatus.
  • FIG. 8 is a longitudinal cross-sectional view taken along the line VIIIVIII of FIG. 6.
  • FIG. 1 there is shown a slide fastener chain 10 which comprises a pair of oppositely disposed stringer tapes 11,11 each carrying along their respective inner longitudinal edge 12 a row of fastener elements E, the stringer tapes 11, 11 being engaged and disengaged by the reciprocal movement of a slider S along the rows of elements E in the usual manner.
  • the fastener elements E may be of 5 a discrete or a continuous type of structure to which sliders may be applied in accordance with the principles of the invention.
  • the inventive principles may be applied not only to an ordinary type of fastener having its elements exposed to external view but also to a socalled concealed type wherein the fastener elements are disposed so as not to be seen when attached to a garment or the like.
  • a slit or cut 13 formed in the midpart of each of the element-free gaps G and extending transversely across the opposed element-carrying edges 12 at an angle perpendicular or slightly inclined to the longitudinal axis of the fastener chain.
  • the fastener chain 10 is moved face up in the direction of the one-headed arrow along a first or horizontal path of travel 14 and then along a second path 15 extending at an angle downwardly inclined relative to the first path.
  • the first and second paths merge at a cornering point 16 which defines a slider assembling station.
  • the movement of the fastener chain 10 is intermittent and is calculated to advance the same a distance corresponding to the length of individual fastener which extends between two adjacent gaps G or more specifically two adjacent slits 13, until the chain 10 is brought to a stop temporarily at a position in which the slit 13 is registered with the slider assembling station.
  • the fastener chain 10 is deflected downwardly around the cornering point 16 functioning as an axis of deflection, whereupon the transverse slit 13 is split open with its upper edge 13a extending parallel with the plane of the first path 14 of fastener chain and aligned with an entrance end S: of the slider S through which the fastener chain is threaded, as better shown in FIGS. 2 and 4. While the fastener chain 10 is held stationary in this disposition.
  • the slider S is moved beyond the cornering point 16 in the direction of the arrow b opposite to the direction of travel of the fastener chain 10 with its entrance end 8-; directed toward the slit 13 which has been split open and inserted therethrough to be mounted on the element-carrying edges 12 of the stringer tapes 11,11.
  • the fastener chain 10 is moved to continue its intermittent travel until the section of the fastener chain at which the slider S has been mounted moves past the cornering point 16 and down along the second path 15.
  • the fastener chain 10 is then stopped upon arrival at the assembling station of the slit 13 in the next section of the chain, thus to repeat the cycle of operation described.
  • the slider assembling apparatus generally designated 17 comprises a guide block 18 having a first guide surface 19 and a second guide surface 20 providing the aforementioned first and second paths 14 and 15, respectively for travel of the fastener chain therealong.
  • the guide surfaces 19 and 20 are each provided therein with a centrally extending, longitudinal guide groove 21 which is dimensioned to fit the portion of the slider S that underlies the lower surface of the fastener chain 10 when the slider is mounted and which is thus adapted to permit the assembled sliders to run in sliding relation to the groove 21.
  • the guide block 18 is provided with a recess 22 extending transversely across the passage of the fastener chain 10 and adapted to accommodate a guide roller 23.
  • This roller is rotatably mounted on a pin 24 secured to the block 18 and is provided centrally with a peripheral recess 23a which is dimensioned to fit the slider S for the same purpose achieved by the guide groove 21.
  • On opposite sides of the peripheral recess 23a are subdivided roll portions 23b of the guide roller 23, which portions are disposed in guiding relation to the respective tapes 11,11 of the fastener chain 10.
  • the guide roller 23 generally defines the assembling station at a point at which the lines of extension of the first and second guide surfaces 19 and 20 merge to form the cornering point 16 where the slider S is assembled on the fastener chain 10. More specifically, the first guide surface 19 extends horizontally in tangential relation to the periphery of each of the roll portions or subdivisions 23b of the guide roller 23, while the second guide surface 20 extends at an angle downwardly inclined relative to the first guide surface 19 and also in tangential relation to the periphery of each subdivision 23b, so that the fastener chain 10 is deflected around the guide roller 23 as it moves past the same, when the slit 13 is split open.
  • Designated at 25 is a slider holder (FIG. 7) having a clamping jaw 25a adapted to releasably hold sliders S one at a time and connected to a suitable actuating means (not shown) for moving the holder 25 towards and away from the slider assembling station as indicated by the two-headed arrow in FIG. 8.
  • the slider holder 25 is arranged to advance toward the assembling station along a horizontal path parallel with the first guide surface 19 and assume a position in which'the entrance end S of the slider S retained therein is directed toward and flush with the upper edge 13a of the slit 13 that has been split open.
  • the holder 25 advances slightly beyond the cornering point 16, threading the slider S through the open slit 13 and thus assembling the same on the fastener chain 10. As this is done, the slider holder 25 is retracted away from the assembling station, whereupon the slider S is released from the clamping jaw 25a and carried away with the fastener chain 10 as the latter begins to move past the guide roller 23 down the second guide surface 20 in the direction of the one-headed arrow.
  • Designated at 26 is a fastener chain separator supported in the guide block 18 for vertical movement into and away from the passage of the fastener chain 10 through a vertical opening 27 extending through the guide groove 21 in the first guide surface 19 adjacent the assembling stationor the guide roller 23.
  • the separator 26 is adapted to separate the two opposed stringers 11,11 as the fastener chain 10 moves past it, so as to present the latter as separated to the assembling station thereby facilitating the slider threading operation.
  • a method of applying sliders to a slide fastener chain having a pair of opposed stringer tapes carrying rows of fastener elements along their respective inner longitudinal edges comprises the steps of:
