  • Emh BALTZER BY l/mmmk his Aflorney United States Patent Int. or. 106211 3/00 U.S. CI. 28-22 3 Claims ABSTRACT OF THE DISCLOSURE A machine for warping and sizing of short warps threads, in particular, for the manufacture of fabric in multi-colored weaving.
  • the machine comprises an improved thread guide system which includes a catch-hook for laying the threads around a pair of winding elements which are mounted in the machine.
  • the catch-hook is rigidly attached to an endless belt which is driven by a pair of opposite pulleys each one of which is coaxially mounted with respect to one of said pair of winding elements.
  • a plurality of levers are operatively mounted adjacent to the endless belt and cooperate with the catch hook for guiding a preselected thread thereto.
  • a bobbin is provided for each thread which is mounted on a bobbin-support arrangement. Furthermore, for each bobbin there is provided a swingable arm on the supporting frame for the winding elements, said arm being adapted to seelctively swing a thread into the path of the moving catch-hook.
  • the swingable arms of this invention have an open hook at their free end for taking up the thread and, in addition, there are mounted a plurality of eyelets on the bobbin-support arrangement.
  • the threads run several times through eyelets, and the threads also remain in these eyelets as they are laid around the winding elements.
  • the eyelets may become chafed, a fact which can contribute to thread breakage.
  • the eyelets may undergo a certain amount of wear which, in turn, can accelerate thread breakage.
  • the eyelets must be made of a material having high-wear resistance, which should be highly polished. The preparation of this material is very costly.
  • an apparatus for the manufacture of short warps especially for the manufacture of weaving-samples in color weaving, as described in more detail in my co-pending application Ser. No. 539,185 and my US. Patent No. 3,247,568.
  • This apparatus comprises winding elements, around which threads of different colors are wound in succession in one layer and in close proximity so that the groups of threads thus obtained as an endless 'belt of threads can be separated in a transverse direction.
  • the apparatus further comprises a thread-guidance system, which includes means that are movable in the direction of the thread path, along the circumferential contour of one of the winding elements.
  • the winding elements are mounted on a stationary supporting frame and have surface elements, which are transversely movable to the winding direction of the thread.
  • a thread-guide is provided, which is preferably formed as a catch-hook, and which is secured to an endless band.
  • the latter is mounted around a pair of wheels, which drive it.
  • the catch-hook cooperates with swingable arms, of which there is one for each thread, said swing able arms being rotatable in front of said endless band so that the threads may be laid around said winding elements.
  • Each swingable arm is provided with an open hook for taking off the thread.
  • a release finger is operatively mounted on the stationary supporting frame, and which can be selectively moved into the path of said catch-hook.
  • FIGURE 1 is a schematic elevation of the apparatus for warping short warp samples incorporating the novel thread-guide system of the invention
  • FIGURE 2 is a partial, schematic side elevation of the apparatus, illustrating the thread-guide system in greater detail
  • FIGURE 3 is a partial, schematic front elevation of the apparatus, illustrating the thread-guide system in greater detail.
  • the apparatus for the manufacture of short warps which is described in my co-pending application Ser. No. 539,185, has side frame members 1 and 2 and a tranverse bottom member 4.
  • the winding elements 5 and 6, which are emboodied as turning cylinders, are rotatably mounted in the frame members 1 and 2.
  • a plurality of bands 9 for supporting threads are transversely movable on the cylinders 5 and 6 and move in the axial direction with respect thereto.
  • the conveyor device 12 serves to pick up one of the threads 37a, 37b, and 37c and winds it around the winding elements 5 and 6.
  • This conveyor device is provided with an endless band 13 that runs around the pair of wheels 14, which are respectively mounted adjacent to the winding elements 5 and 6.
  • Two projecting shaft members are rotatably mounted in the frame member 2 and are instrumental for crossing the threads that are being wound around the winding elements 5 and 6.
  • the thread-guide system includes a catch-hook 58 for changing threads of different colors.
  • the catch-hook 58 is rigidly connected to the endless band 13 and cooperates with the swingable arms 59a, 59b 59k.
  • the free end of each swingable arm is provided with a hook 70a70'k, into which the thread is hooked.
  • the swingable arms 59a, 59b 59k are controlled individually and independently by rotary magnets 62a, 62b 62k.
  • Bobbins with threads of different colors for the manufacture of short warps for multicolored weaving are mounted on the bobbin-support stand 63.
  • the threads run from the bobbins through movably mounted eyelets 71a, 71b, 710 to the hooks 70a70k of the swingable arms 59a, 59b 59k, where they are engaged by the hooks 70a-70k and run from there further to the frame member 1, to which they are secured at a suitable spot.
  • the swingable arms 59a, 58b 59k take up the position I, illustrated in FIG. 3, that is, a position lying behind the lower wheel 14.
  • the threads 37a, 3712 run along a path which is spaced from the revolving endless belt 13 and the catchhook 58, so that, on rotation of the catch-hook 58, the threads running along the path indicated by the dot-dash line 74 in FIG. 3 cannot be caught by the catch-hook 58.
  • the corresponding swingable arm 59a, 59b, 59c for the corresponding bobbin 36a, 36b, 360 is swung into the position II, illustrated in FIG. 3, by the corresponding rotary magnet 62a, 62b, 62c.
  • the thread then runs along a path indicated by the dot-dash line 75 in FIG. 3 as the end of the thread is adhesively attached to one of the bands 9 of the winding element 6.
  • the thread is thus positioned in front of one of the catch-hooks 58, which are secured to the endless band 13, in such a way that the said hook, during its movement, takes up the thread and lays it around the winding elements and 6.
  • the other threads remain in the position indicated by the dot-dash line 74, indicated in FIG. 3 and, consequently, cannot be touched by the catch-hook 58.
  • the release-finger 72 is actuated and swings into the position indicated by the dot-dash line in FIG. 2 by means of a rotary magnet 73, thereby bringing it into the path of the catch-hooks 58. This causes a release of the thread from the catch-hook 58. The thread thus taken off falls back on to the prepared hook 70a, 70b, 700 of swingable arms 59a, 59b, 59c again.
  • release-finger 72 can be controlled by a punched card, which can be inserted into the slit of the machine provided for this purpose; in this manner, the width of a layer of threads can be easily selectively determined.
  • a machine adapted for the warping of short-warp threads in multicolor weaving, comprising, in combination, a pair of winding elements operatively mounted in said machine; continuous transverse thread-feeding means operatively mounted on said pair of winding elements for continuously transversed feeding the thread during windings; thread winding and conveyor means mounted adjacent said pair of winding elements and adapted to wind up in a simple layer of thread around said pair of winding elements; an endless band, mounted around said winding and conveyor means; thread take-up means operatively mounted on said endless band; a bobbin-support carriage, mounted adjacent to said machine; at least one bobbin operatively mounted in said support carriage; at least one swingable arm having an open hook at its free end, being operatively mounted on said machine, adjacent to said winding and conveyor means, said swingable arm being adapted to selectively take up and release said thread from said bobbin; first rotary magnet means operatively connected to said swingable arm and adapted to pivot the latter toward
