Abstract
The invention relates to a weaving loom with waving shed heddle frames which when built in accordance with the invention insures that the heddles do not have lateral displacement when the frames are operated by controls respectively acting on both sides of the frames so that the motions of the respective sides differ from each other in their pattern. The bars of the frames are pivotably connected to the supports of these frames. These supports slide in stationary guides which restrict the lateral motion of the frames.
Claims13
A weaving loom having a waving shed comprising:
- propelling means for introducing and propelling a weft thread into the shed wherein the weft thread is inserted by unwinding a specific length of thread from one side of the loom;
- a plurality of frame means wherein each frame means includes:
- a width to extend throughout the width of a cloth to be woven,
- heddle holder rods, bars, and supports wherein the opposite ends of said bars are moveably connected to opposite ends of said supports at points aligned with the axes of said heddle holder rods;
- stationary guides adapted to direct said supports in their reciprocating cycle to restrict lateral motion of each frame;
- controls adapted to permit each end of each frame to proceed through its reciprocating cycle independantly of the opposite end;
- and
- a reed for pushing each pick of inserted weft thread.
A weaving loom comprising:
- a plurality of heddle frames, each frame being defined by two laterally spaced rigid crossbars, and by two supports which are pivotably connected between opposed ends of said crossbars to permit variation of the angle between said supports and said crossbars;
- and
- guide means slidably associated with at least one support of each heddle frame to minimize lateral displacement of heddles of each frame upon displacement of said frames during use.
A single-phase weaving loom having a waving shed, and a stationary spool located outside of the shed from which a specified length of weft thread may be pulled comprising in combination:
- means to introduce the weft thread into the shed in the shape of a loop with one locked strand and one mobile strand;
- a plurality of frames defined by rigid frame members having controls respectively acting on both sides of said frames adapted to permit travel in differing patterns of the heddles operated by each frame and each frame being defined by frame bars having heddle holder rods and frame supports which are movably attached to the frame bars at points aligned with the axes of the heddle holder rods in each frame means;
- stationary guides adapted such that these supports may slide in stationary guides restricting the lateral motion of the frames;
- a reed equipped and controlled so that its teeth progressively and firmly push the inserted length of weft thread from where it enters the shed towards where it emerges.
