<p>An apparatus is disclosed for feeding flat weft tape from a supply package to a loom in which the weft tape supply package is rotatably mounted outside the warp shed. The apparatus comprises a rotatable chuck adapted to support the weft tape package; means to intermittently rotate the rotatable chuck; a weft tape storage device; an aspirator adapted to draw the weft tape tangentially from the rotating supply package and feed it into the weft tape storage device; weft tape insertion means on the loom adapted to draw the tape from the storage device and insert it into the warp shed of the loom; control means for the means to intermittently rotate the rotatable chuck adapted to synchronize the starting and the stopping of the chuck with the starting and the stopping of the loom; a course control means adapted to adjust the rotation of the chuck such that the surface of the supply package moves at approximately the speed required to unwind the same length of weft tape as is inserted into the warp shed of the loom by the weft insertion means, and a fine control within the weft storage device and actuated by the length of tape in the storage device adapted to more accurately adjust the rotation of the chuck. The apparatus is useful in the weaving of fabric from flat tapes, e.g., flat polyolefin tapes.</p> |
