Pat. No. 2,300,442, issued Nov. 3, 1942, and is an improvement over the apparatus and machine shown in US. Pats. No. 3,145,523, issued Aug. 25, 1964 and No. 3,196,489, issued July 27, 1965. i
  • segmental or interrupted arrangement of the carriers also introduces a structural weakness in the machine which appears upon attempts to operate the machine at high speed. Accordingly, the maximum speed of operation of the machine and the productive capacity of the apparatus or machine are limited.
  • It is a further object of this invention to provide an improved coiling machine including a rotatable member to which a continuous length-of filament is delivered havinga needle-like mandrel arranged axially thereof and extending outwardly therefrom which mandrel is preferably rectangular-shape in cross section and positioned at a point off-set from the axis of rotation of the rotatable member with the rotatable member applying tension to the filament as it passes therefrom to the mandrel so as to be wound therearound upon rotation of the rotatable member to form a coiled filament therearound whereby the filament is subjected to a greater tension around the mandrel during the rotation of the rotatable member through one part of a revolution.
  • an improved coiling machine including a pair of opposed rotatable members with each having a spool of filamentary material wound therearound with the rotatable members together with the spools arranged on horizontal axes and in alignment with one another, a needle-like arcuated mandrel around which the filamentary material is adapted to be wound to form a pair of coiled filaments arranged axially of each of the rotatable members and with the free ends extending outward therefrom and dis-' posed in grooves and cavities arranged in and around the periphery of a forming wheel into which grooves and cavities the coiled filaments are delivered from the free ends of the mandrels wherein the filaments are shaped, sized and cured during the rotation thereof on an axis parallel to the axes of rotation of the rotatable members.
  • It is still another object of the invention to provide a coiling machine including a forming wheel for curing the filaments having grooves and cavities arranged in and around the periphery thereof for receiving the coiled filaments from the ends of arcuated needle-like mandrels with these mandrels being constructed and arranged relative to the forming wheel so that practically the full circumference of the wheel is utilized for curing the coiled filaments whereby lower curing temperatures may be used which results in the coiled filaments maintaining their shape for a longer period of time.

  • FIG. 8 is an enlarged fragmentary view, partly in section, of a portion of the forming wheel showing the coiled filaments positioned in the grooves and cavities therein, and
  • FIG. 9 is an enlarged isometric view of a portion of a completedcoiled filament as produced by the machine.
  • the product manufactured by the machine of the present invention is a continuous coil, two identical coils in the present instance, preferably of a thermosetting plastic filamentary material, such as nylon, to be used in the construction of slide fasteners of the filament type.
  • the product, designated by C, as more clearly shown in FIG. 9, is made by winding the filament F around a stationary mandrel in a manner and by mechanism hereinafter to be described.
  • a cobra-like head portion or crown H is formed in each convolution at one side thereof for a purpose well known to those skilled in the art.
  • FIGS. 5 and 7 of the drawings There is provided a pair of arcuate-shaped needle-like mandrels '5 having one end affixed to this bushing 4 at a point ofiiset from the axes of rotation of the rotatable members 2, as more clearly shown in FIGS. 5 and 7 of the drawings.
  • These needles 5 are preferably rectangular shape in cross section, as more clearly shown in FIG. 7, which is one of the most important aspects of the invention.
  • these needle-like members 5 are shown rectangular shape in cross section they may be of any cross-sectional shape providing they have a pair of spaced-apart realtively sharp corners on one side thereof, as at 5a.
  • a forming wheel 6 which is mountedon a rotatable shaft 37 arranged substantially parallel to the shafts 3 and the axes of rotation of the rotatable members 2.
  • this wheel 6 there is arranged in side-by-side relation a pair of grooves 7 having spaced-apart cavities 7a arranged around the circumference.
  • the free end of each of the needle-like mandrels 5 is disposed in these respective grooves which grooves are adapted to receive the coiled filaments C with the convolutions disposed in the cavities 7a as clearly shown in FIGS. 7 and 8, as they pass from the ends of the mandrels.
  • this forming wheel 6 is heated preferably by heating members 6a arranged annularly therearound or by any other suitable means which in turn are adapted to heat the coiled filaments to soften and set the same as they are conveyed thereby therearound.
  • a pair of cage-like reel members 8 having circular ends 9 with a plurality of rods 10 extending therebetween and a pair of hollow shafts 12 upon each of which a spool S of the filamentary material F is adapted to be disposed, as shown in FIG. 1. It will be seen that these hollow shafts 12 telescope the respective stationary shafts 3 and are adapted to rotate therearound and that these hollow shafts 12 are connected to the respective rotatable members 2 so as to be rotated therewith.
  • a pulley 30 on the end of the shaft 17 which drives a reduction mechanism (not shown) which, in turn, rotates the forming wheel 6 by means of a sprocket or pulley 31 arranged on the shaft 37. It will be understood that this reduction mechanism rotates the forming wheel 6 in timed relation to the rotation of the hollow shafts 12 and the spools S positioned thereon.
  • an endless flexible metallic band 20 which is disposed around a plurality of guide pulleys 21.
  • This band is driven frictionally by the wheel 6 upon rotation thereof and it is the purpose of the band to maintain the coiled filaments C in the grooves 7 as the wheel rotates.
  • a spool S of filamentary material F is positioned on each of the rotatable shafts 12, as shown in FIG. 1.
  • the filamentary material F passes from the spool S around the outer sides of the respective rods 10-, around pulleys 22 carried by one of the rods, over and around a series of pulleys 23 and 23a arranged at the inner end of the reels 8.
  • the pulleys 23 are arranged on the outer end of the levers 40 which are pivotally attached, as at 41 to the respective reels 8 and the pulleys 23a are rotatably mounted on the respective circular ends 9.
  • levers are spring loaded and are adapted to control a variable tension mechanism which controls a frictional shoe device arranged on the inner circular ends of the respective reels 8 for driving frictionally the spools S so as to compensate for the amount of filamentary material F being drawn from the respective spools as the coiled filaments are being formed and the amount of filamentary material on the spools is being depleted. It then passes through tubular guide members 24 and around a pulley 25, then parallel to the shafts 12. and then through apertures 26 in the rotatable members 2. to the inner end of the respective mandrels 5 directly next to the respective bushings 4. and around the mandrels. The machine is now in readiness for operation.
