摘要： A tufting machine comprising a plurality of needle holders (11) associated with a needle bar (5) and slidably supported in a frame for reciprocation in a needle reciprocation direction. A respective needle (10) is attached to each needle holder (11), each needle holder having an engagement portion. The needle bar (5) has means (7, 13) for selectively latching with the engagement portion of each selected needle holder so as to selectively drive latched needle holders in the needle reciprocation direction. A stop bar (21) is positioned to limit the upward movement of the needle holders (11). At least one magnet (20) retains non-latched needle holders in its uppermost position as the needle bar is reciprocated. The magnets (20) are embedded in the stop bar (21). The machine further comprises a cushioning member (27) attached to the magnet (20) and facing the top of each needle holder (11).

摘要： A presser foot module (50) for a tufting machine. The module has a module body (13) for attachment to a tufting machine and the plurality of fingers (12) extending from the body in a first direction which, in use, is opposite to the direction in which the backing medium (1) is fed through the tufting machine. The module body (13) has a downwardly depending lip (53) defining a presser surface (53A) extending across an end of the body which is adjacent to the interface with the fingers (12). Each finger (12) has an unsupported end opposite to the module body (13) so as to provide access to an open gap between adjacent fingers in a direction opposite to the first direction.

摘要： A rapier weaving machine and a method for converting an existing rapier weaving machine into a rapier weaving machine, which includes an insert rapier head for inserting a weft yarn into a fabric, a receiver rapier head for receiving and holding the weft yarn and subsequently pulling the weft yarn out of the fabric in a movement direction, an opening element for opening the receiver rapier head in order to release the weft yarn, and a guiding device, positioned on the side of the receiver rapier head opposite the opening element, and comprising a guiding block for adjusting the movement direction of the receiver rapier head, and a rotatable guiding wheel for restraining the receiver rapier head when opening.

摘要： A pattern data processing system configured to determine and compensate for any points of entanglement between different yarns. A point of entanglement is defined as a point where the yarn from one needle crosses and traps the yarn from another needle on the back face of the backing medium. The pattern data processing system is configured to calculate the additional length of back stich caused by each point of entanglement by subtracting an ideal back stich length, calculated as the path which would have been taken by the yarn had it not been entangled in another yarn, from an actual yarn path, calculated as the actual length of the entangled yarn. A controller is configured to include in the amount of yarn fed by a respective yarn feed mechanism for each stitch an amount equivalent to the additional length of back stitch. The invention also includes a tufting machine and method of operating the tufting machine with the pattern data processing system.
