Title: Heald and a method for the manufacture thereof
IPC: D03D29/00
Filed: 1978-03-03
Abstract: Heald (10) composed of textile thread, which consists of two crocheted threads (11, 12) and in which each individual knot, which, in the healds known hitherto, connects the two twisted or smooth thread parts to form the heald eye, is replaced by interlaced ladders of two stitches located next to one another in the two crocheted threads (11, 12). The looping points (13, 14, 15, 16) are formed at predetermined points along the two threads, for the purpose of producing the closed heald with its eye (17). This novel heald is produced on a knitting machine with a constant bundle length and is then combined in a bundling machine. The use of the novel heald does away with all the problems which occur in tying by hand, such as for example, time-consuming work, and knots which, in the few thousand healds located next to one another on the heald frame, are considerably thicker than the actual thread material and form bulges which give the combined healds a non-uniform width.

Title: Method and apparatus for opening and mixing fiber bales
IPC: D01G13/00
Filed: 1980-09-26
Abstract: A method an apparatus for opening and mixing the fibers from a plurality of bales according to a predetermined mixture. The device includes tongs-like gripper means which press into the fiber bales for removing fibers therefrom. A measuring means and a control means determine the width of opening of the gripper means. A control circuit is provided for receiving a signal representing the weight of the first pick-up from a particular bale and the weight of the fibers deposited in a receiver container. When the sum of these signals is equal to the preset desired weight of the fibers that are to be deposited in the receiver container, a compared signal is produced causing the tongs on successive pick-ups to be opened to a lesser degree. As a result, a high degree of accuracy is obtained when mixing to a predetermined ratio while maintaining a high production output.
