Abstract: A pile loop forming assembly for looms for reliably transferring yarn from one side of the lance to the other in order for the yarn to be wrapped around the lance to form a loop. The loops may be cut by a blade as the loops advance and ride over the blade edge. The loops are formed by yarns passing through reed fingers wherein lances move the yarn from one side of the reed finger to the other. The lances are attached to a bar, which moves linearly in alternate directions so as to wag the lances to either side of the reed space. A heald moves the yarn up or down to selectively engage or disengage from the lances. A guide formation on a portion of the reed space helps deflect the yarn from one side of the lance to the other. The reed can pivot between a beat-up position and a weft insert position. As the reed moves to the beat-up position it engages the newly formed pile loop on the lance and pushes it to the fell.

Abstract translation: 一种用于织机的桩环形成组件，用于将纱线从喷枪的一侧可靠地传送到另一侧，以使纱线缠绕在喷枪上以形成环。 当环路前进并且越过叶片边缘时，环路可以被叶片切割。 这些环由穿过舌头的纱线形成，其中长矛将纱线从芦苇手指的一侧移动到另一侧。 喷杆连接到杆，其在交替的方向上线性移动，以便将喷枪摆动到簧片空间的任一侧。 综览将纱线向上或向下移动以选择性地接合或脱离喷枪。 在芦苇空间的一部分上的引导形式有助于将纱线从喷枪的一侧偏转到另一侧。 簧片可以在打纬位置和纬纱插入位置之间枢转。 当芦苇移动到殴打位置时，它将与新形成的桩环相结合，并将其推到坠落处。

Abstract: A loom for weaving pile fabric is disclosed, including a plurality of healds for shedding warp yarns, a pile-forming reed through which said warp yarns are guided and a plurality of pile loop forming lances extending in the warp direction so that each pile-forming lance passes through an associated dent in the read, each dent being defined between a pair of spaced apart dent fingers. Each loop forming lance and at least one dent finger of said pair of dent fingers cooperate to guide lateral displacement of the loop forming lance relative to said associated dent. A first group of healds are threaded with ground forming warp yarns and the first group of healds and the loop forming lances are arranged such that the upper and lower shedding positions of said ground forming warp yarns are located below the loop forming lances. A second group of healds are threaded with loop forming pile yarns, the second group of healds and said loop forming glances being arranged such that each loop forming yarn may be moved from a lower position located beneath an associated loop forming lance to an upper position located above said associated loop forming lance. A guide system is provided for guiding movement of each loop forming warp yarn such that during movement from its lower position to its upper position it passes by one side of said associated lance and during movement from its upper position to its lower position it passes by the opposite side of said associated lance to form a loop held upon said associated lance.
