  • This invention relates to an apparatus for beating up the filling thread in a flat weaving machine, which apparatus comprises an intermittently rotating reed roller which consists of a multiplicity of thin discs aligned on a common shaft and provided with dogs which extend between the warp threads and beat up the filling thread againstthe fell of the cloth guided by a support adjacent to the fell.
  • the reed discs have a helical guide edge which extends around more than a complete circumference so that there is a threading slot between the leading and trailing ends of said guide edge.
  • the shuttle must insert the filling thread intov this threading slot so that the subsequent rotation of the reed shaft results in a displacement of the filling thread along the guide edges of the reed discs and the filling thread is gradually advanced toward the fell of the cloth and is held between the upper and lower warp threads and the guide edges.
  • the gradually increasing radius of the guide edge permits of a forcing of the filling thread against the fell only with a small force so that only a small number of filling threads per unit of length can be obtained.
  • the filling thread is forced against the fell only until the ends of the guide edges have moved past the fell. Thereafter, the filling thread can separate from the fell before the filling thread is tied in by the next change of shed.
  • the reed shaft must be rotated through more than 360 between two changes of shed so that the operation can be carried out only at a relatively slow rate.
  • the filling thread can be inserted into the slot between the leading and trailing ends of the guide edge only if the reed shaft is exactly in a predetermined position during each pick because a projection carried by the shuttle must pull the filling thread through the threading slots of all reed discs.
  • the reed discs have dogs which protrude from the periphery of each disc and enter between the warp threads and beat up the filling thread against the fell.
  • the sides of the protruding dogs beat up the filling thread firmly against the fell
  • the apparatus has the disadvantage that the dogs cannot retain the thread at the fell but must be moved past the fell on the underside thereof so that the filling thread which has been beaten up or the cloth may be damaged.
  • the support for the cloth must be comblike and the spaces between the teeth of the comb must be so wide that the dogs of the reed discs can pass therethrough.
  • a pressure roll is provided, which forces the woven fabric against the sup- Y port on that the cloth cannot yield to the dogs and to ensure that the filling thread is beaten up against the fell. Because the cloth is forced against its support, on the other hand, the dogs cannot be moved in a simple manner past the fell on the underside thereof so that difficulties must be expected to arise in the operation of this known apparatus. Besides, the dogs extend between the warp threads in succession so that they may fail always to extend into the same spaces between warp threads and the appearance of the cloth may thus be adversely affected.
  • the intermittently rotated reed comprises a multiplicity of star-shaped discs and is rotatably mounted in a bell-crank lever which is oscillated by a crank mechanism so that the reed is also periodically moved up and down.
  • the reed discs rotate below the fell when they have beaten up the filling thread against the fell so that the star-shaped reed discs cannot damage the fell.
  • a rod which is capable of a limited angular movement extends under the warp throughout the width thereof close to the line in which the open reed enters the warp.
  • the warp can be slightly lifted and flattened shortly before the reed enters the warp. In this way, a correct, uniform entrance of the reed-into the warp is ensured.
  • the lower warp threads are raised into the plane of the upper warp threads so that the teeth of the open reed can always enter the same spaces between the warp threads.
  • the support can be pivotally moved in a simple manner.
  • the pivotal movement of the support at the beginning of each angular step of the reed ensures also that the dogs continue to force the filling thread against the fell against which the thread has been beaten up and until the thread has been tied in and held in position as a result of the change of shed.
  • a cam bar is provided, which is displaceable in parallel to the pivotal axis of the support and is preferably hydraulically operable, and followers are operatively associated with the support and bear on the cam bar. If the intermittent rotation of the reed is hydraulically controlled, the pivotal movement of the support can easily be synchronized with the rotation of the reed by the cam bar so that the several operations consisting of the change of shed, the pivotal movement of the support and thereafter the rotation of the reed shaft will be performed in the correct sequence and without a disturbance.
  • the use of the cam bar also affords the advantage that even multi-part supports, particularly when wide cloth is woven, can be raised uniformly and quickly.
  • the support is pivotally moved, it may be provided adjacent to the fell in a desirable manner with a continuous straight edge, such as is conventional in machines having an oscillating reed.
  • the manufacture of the support is much simplified and the filling thread is beaten up much more uniformly.
  • the tendency of the support to become soiled is reduced and particles abraded from threads or the like can be more easily removed.
  • FIG. 1 is a transverse sectional view showing an apparatus for beating a filling thread into the fell of a fabric according to the invention
  • FIG. 2 is a sectional view taken on line "-11 of FIG.
  • the apparatus according to the invention for beating up the filling thread comprises an intermittently rotating reed roller which comprises a multiplicity of thin discs 2, aligned on a common shaft 1 and having dogs 3 which extend between the warp threads and beat the filling thread against the fell of the cloth.
  • the cloth is supported adjacent to the fell by a support 4 mounted by pivoted levers 7 on breast beam 6 for rotation on a pivot 5 extending parallel to the reed shaft 1.
  • a cam bar 8 is also mounted in the breast beam 6 and is displaceable parallel tothe pivot 5 to impart a pivotal movement to the support 4.
  • Follower members 10 are provided with rollers 9 restingon the cam bar 8 and, upon a longitudinal displacement of the cam bar 8, force the followers against the pivoted levers 7'so that an upward pivotal movement is imparted to the levers 7 and the support 4.
  • the dogs 30f the reed discs 2 can then be rotated freely past the support.
  • the pivoted levers 7 are provided with inserted resilient pads 12 engaged by the followers 10.
  • a stationary comb 13 is associated with the reed l, 2 and serves for an exact guidance of the warp threads.
  • the teeth of the comb 13 extend approximately tangentially to the outer flight circle of the dogs 3 of the reed discs 2 so that, owing to the small distance between the comb and the reed each reed, disc 2 always enters the same space between warp threads.
  • an additional comb 14 is provided, whose teeth extend between the reed discs approximately in the radial direction thereof.
  • the cam bar 8 When the filling thread has been inserted into the shed and placed between the combs 13 and 14 in front of dog 3 of the reed disc 2 (see position of FIG. 1), the cam bar 8 is operated to raise the support 4 and the cloth, and the reed shaft is rotated through an angle which corresponds to the angular spacing fo the dogs so that the filling thread is engaged and beaten up against the fell of the cloth by the corresponding dog of each reed disc. Support 4 is lowered when the corresponding dogs 3 have been rotated past the support so that the next following dogs can strongly beat up against the fell during the rotation of the reed.
  • the reed discs 2 force the filling thread against the fell until the shed has been changed so that the filling thread has been tied in and fixed in position. Because the filling thread is retained against the fell, the filling thread cannot become loose before it has been tied in. For this reason a cloth having a particularly large number of filling threads per unit of length can be woven.
  • the support 4 is again raised for a short time and the discs 2 are caused to perform another angular step.
  • the dogs 3 are withdrawn from between the warp threads at the fell and are moved past the fell belowthe same.
  • the support 4 may be provided in a very simple manner with a continuousstraight edge 16, which does not only promote a more uniform beatingup of the filling thread against the fell of the cloth but also facilitates the removal of any dust which has been abraded from the threads.
  • a reed comprising a. a reed shaft having an axisextending parallel to the pivot axis" of the support, b. a multiplicity of reed discs corotationally mounted on the reed shaft and having dogs 6 adapted to extend between the warp threads and 2.
  • said to beat successive ones of the filling threads means for pivotally moving said support comprise agamst the fell and a cam bar which is displaceable parallel to said pivc.
  • the reed shaft being operable to perform a succession of angular movements for beating the 5 successive filling threads against the fell, and followers beanng on Sald cam bar and operatwely as 4.
