Abstract
A roll (25) of woven fabric (30) having a length greater than the diameter thereof wherein the diameter (28) is substantially the same across said length of the roll. An assembly (50) operable with the tucking units of the picking (51) and receiving (52) ends of a weaving loom (53) for producing woven fabrics (30) comprises plate means (74) attached to the loom; main drive block means (76) connected to a harness (60) of the loom; operating rod means (78), having first and second ends (92, 95) and attached to the main drive block means at the first end (92) and pivotally mounted to an upper surface of the plate means at the second end (95); lifter means (80) connected to the operating rod means, proximal to the second end, for lifting the weft end gripper (70) of the loom; and means for selectively engaging (82) the weft end gripper, operatively associated with the operating rod means, whereby the weft end gripper positions consecutive pick lines (32) in an alternating fashion, allowing every other one to be tucked into the selvage of the fabric, while adjacent pick lines are untucked. A method for producing woven fabrics (30) having a tucked-untucked selvage comprising providing an…
