On the loom, the warp yarns are withdrawn from the weaving shaft, bypassing the back beam, passing through the stop sheet, the eyelets and the weirs to the weaving mouth, and interlacing with the weft yarn to form a fabric. The fabric is passed around the chest beam and, after being driven by the take-up roll, is wound onto the take-up roll by the guide rolls. When the warp yarns are interlaced with the weft yarns, the heald frames are respectively moved up and down, so that the warp yarns that are inserted into the eyelets are divided into two layers to form a shed for introducing the weft yarns into the shed. When the weft yarn is introduced through the warp layer, it is pushed toward the weaving shed by the cymbal on the sley. In order for the interlacing to proceed continuously, the finished fabric is drawn away from the work area and the warp yarns on the weaving shaft are brought into the work area. In order to complete the interweaving of the warp and weft yarns, the loom must have five basic movements of opening, weft insertion, beating, winding and passing, each of which is completed by a corresponding mechanism.
