Definitions

  • ABSTRACT A method and apparatus for the production of individual product lengths of slide fastener from a continuous chain thereof, said apparatus including means frictionally feeding the chain, means applying end stops to the same and cutting it to a desired length and chain guiding means interposed adjacently between the first and second mentioned means.
  • This invention relates to a method of an apparatus for finishing sliding clasp fasteners and more particularly to such method and apparatus which is designed to apply end stops to and cut a slide fastener chain of continuous length into individual product lengths.
  • the garment manufacturers prefer to purchase a continuous lengthchain, instead of measured individual lengths, of slide fastener and cut the chain to desired product lengths at their end. Then, they assemble the fasteners with sliders and end stops in the course of sewing or otherwise attaching the fasteners to garments and the like.
  • This practice is advantageous in that the manufacturers can freely select the cutting lengths of fasteners to suit their particular application and further in that they can dispense with added process of forming element-free gaps or attaching top end stops beforehand depending upon the nature of garments, thus offering a saving in the manufacturing costs.
  • FIG. 4 is a cross-sectional view of a guiding means for guiding the movement of the fastener chain.
  • FIG. 1 there is shown a continuous length fastener chain F which comprises a pair of opposed stringer tapes T,T each carrying along their respective longitudinal edges a row of fastener elements E, the stringer tapes being coupled together through the medium of the fastener elements E' which have been meshed with one another.
  • the fastener chain F is not provided with pre-formed element-free gaps or spaces which are utilized as a target for cutting the chain to measured lengths according to the conventional practice.
  • the invention is directed to the provision of measured lengths of sliding clasp fastener units having bottom end stops from a continuous fastener chain comprised of a pair of opposed stringer tapes carrying along their respective longitudinal edges two rows of continuously meshed fastener elements, and the pro cess comtemplated herein comprises holding the fastener chain closely adjacent the longitudinal edges of its stringer tapes along which the rows of fastener elements are secured, feeding the fastener chain intermittently in a horizontal path of movement for a distance corresponding to a selected length of an individual product fastener, discontinuing the feeding of the fastener chain, applying a bottom end stop to the fastener chain adjacent a leading end thereof, cutting the fastener chain at a point forwardly beyond said bottom end stop, and withdrawing the thus cut fastener chain.
  • FIG. 2 A preferred form of apparatus which is employed to carry the above process into practice is shown in FIG. 2, and this apparatus designated at 10 generally comprises a feeding means 11 for feeding the fastener chain F intermittently in a horizontal path of movement, a guiding means 12 for guiding the movement of the fastener chain F, a bottom-end stop applying means 13 for applying bottom end stops to the fastener chain, a cutting means 14 for cutting the fastener chain into individual measured lengths, and a withdrawal means 15 for withdrawing the cut-off fastener chain.
  • a feeding means 11 for feeding the fastener chain F intermittently in a horizontal path of movement
  • a guiding means 12 for guiding the movement of the fastener chain F
  • a bottom-end stop applying means 13 for applying bottom end stops to the fastener chain
  • a cutting means 14 for cutting the fastener chain into individual measured lengths
  • a withdrawal means 15 for withdrawing the cut-off fastener chain.
  • the feeding means 11 comprises a pair of rollers 16 and 17 arranged in vertically opposed relation such that the fastener chain F is engaged between the peripheries of the two rollers and frictionally driven thereby in a horizontal direction toward an assembling and cutting station later described.
  • the lower roller 16 is a drive roller connected to a motor not shown and also to a pulse wheel 18 through a suitable gear arrangement not shown.
  • the amount of each intermittent cycle of rotary movement of the drive roller 16 which determines the length of individual product fasteners to be produced from the chain F is pre-set by a suitable electronic control device such as a digital counter not shown which is electrically connected to a non-contact switch formed by the pulse wheel 18 and a proximity switch electrically connected therewith 19, the arrangement being that completion of each selected intermittent cycle of revolution of the drive roller 16 is sensed by the noncontact switch whereupon a signal is produced to deenergize a clutch device through relays to stop the roller 16 for a predetermined time interval during which the chain F is assembled with a bottom end stop and cut to a measured length as hereinafter described.
  • a suitable electronic control device such as a digital counter not shown which is electrically connected to a non-contact switch formed by the pulse wheel 18 and a proximity switch electrically connected therewith 19, the arrangement being that completion of each selected intermittent cycle of revolution of the drive roller 16 is sensed by the noncontact switch whereupon a signal is produced to deenergize a clutch device through relays to stop the roller
  • the upper roller 17 is an idling guide roller which is provided around its peripherywith a continuous circumferential recess 20 dimensioned to accommodate the two coupled rows of fastener elements E as shown in FIG. 3.
  • the recess 20 is defined by relatively narrow opposite circumferential ribs 21,21 having abutting faces 21a,21a disposed astride of the fastener elements E and adapted to hold the stringer T,T close thereat against the periphery of the drive roller 16.
  • This structural feature of the guide roller 17 ensures that the fastener chain F is fed and guided straight with a minimum of stresses tending to bias the direction of its movement.
  • the guided movement of the fastener chain F is further improved by the guiding means 12 better shown in FIG. 4 which comprises an elongated panel 22,.having longitudinal side flanges 23,23 defining therebetween a wide guide channel 25 providing an unresitricted passage for the stringer tapes T,T and opposed parallel guide rails 24,24 defining therebetween a narrow guide channel 26 dimensioned to conform substantially with the width of the two interengaged rows of elements E such that the inner walls 24a,24a of the respective rails 24,24 are disposed in sliding engagement with the rear portions Ea of the elements E thereby permitting the fastener chain F to advance along a straight line of path without swerving sidewise.
  • the guide panel 22 has a width; viz. a distance between the side flanges 23,23 greater than the width of the fastener chain F, and the guide rails 24,24 have their lower ends 2412,2411 disposed short of the surface of the chain F, with no other parts of the panel 22 coming into the path of the fastener chain F so that the latter is freely advanced while being guided by the rails 24,24.
  • Designated at 27 is a supporting bed having a smooth sliding surface 27a on which the fastener chain F is laid flat and move slidably as it is fed by the feeding means 11.
  • an assembling and cutting station including a bottom end applying means 13 comprising a vertically reciprocable punch 28 mounted in the upper frame and normally retracted above the path of the fastener chain F and a clamping die 29 fixedly mounted in the supporting bed 27.
  • This punch and die arrangement is conventional and applies a bottom end stop P to the fastener chain F at a predetermined position.
  • the punch 28 for instance may include a means of cutting a continuous length strip of blank metal into individual pieces of staple-like form or may be arranged simply to receive preformed staple-like stop members from a separate source.
  • the cutting means 14 included in the said station which is located forwardly of the end stop applying means 13 and which comprises a vertically reciprocable cutter 31 mounted in the upper frame 30 and a coacting stationary cutter 32 provided in the supporting bed 27.
  • This cutter arrangement is also conventional and cuts the fastener chain F transversely across adjacent to the assembled end stop P as at the thickened solid line in FIG. 1.
  • a spring-loaded pressure pad 33 accommodated in the supporting bed 27 and normally facing in registry with the path of the fastener chain F.
  • the pressure pad 33 is depressed by the punch 28 and lowered below the path of the fastener chain F.
  • the pressure pad 33 is returned by the action of the spring 34 to a level flush with the path of the chain F thereby maintaining normal straight posture of the chain F to permit the same to be taken up without fail by a withdrawing means 15 hereinafter described.
  • the withdrawing means 15 is provided for withdrawing the preceding unit of the fastener which has been assembled and cut from the continuous ensuing fastener chain F, which means comprises a pair of rollers 35 and 36 between which the cut-off fastener is frictionally engaged and thereby withdrawn for collection for example in a suitable basket.
