    摘要: An electromagnetic unit to stop the weft yarn in measuring weft feeders for fluid jet looms, includes a rod movable along its axis under the control of at least one electromagnetic coil so as to insert one of its ends, with slack, into a corresponding hole of the weft feeder drum and engage with that end the weft yarn on the side to stop its unwinding from the drum. Onto the movable end of the rod engaging the weft yarn a bush is mounted for mating with the edge of the drum hole for insertion of the rod end, and the sliding of the bush towards the drum taking place with delay in respect of the movement of the rod towards the drum.

    摘要: A weft yarn deflection brake including a braking element 5 which can be adjusted in timed fashion and by its variable braking force, a drive motor 6 for said braking element and a control device CU connected with said drive motor 6 is equipped by a position detection means E associated to said braking element 5. Said position detecting means E is connected to an adjustment means 9 for functional parameters of the deflection brake. During operation functional parameters as e.g. the braking force and the time of the activation of the deflection brake are varied adaptively in order to assure a performance of the deflection brake which is deemed to be optimal for the insertion system. At selected points in time known target positions of the braking element are set and compared with the actual positions. In case that deviations are detected a respective functional parameter is varied.

    摘要: A yarn processing system includes a weft yarn feeding device with a control unit and a power loom which consumes weft yarn. In operation, a run-signal is generated by the power loom that initializes the start-up of the weaving operation. A start-signal that is derived from the run-signal is transmitted to the feeding device. The start-signal is generated externally of the feeding device. The drive motor of the feeding device is driven at a predetermined speed, after receiving the external start-signal in order to prevent an undesired reduction of the size of a yarn store by the initial consumption demand of the start-up of the weaving operation of the power loom. A signal transmitting connection is provided in the yarn processing system between the power loom and a control unit of the feeding device for transmitting the start-signal. On start-up of the power loom, the drive motor of the feeding device is operated at a predetermined speed by the control device independent from the size of the yarn store in the feeding device.

    摘要: A yarn brake includes a fixed frame, fixed and spaced-apart yarn guide elements defining together a straight yarn path through the yarn brake, a rotation drive, and at least one braking element projecting from the rotation drive beyond the straight yarn path. The braking element is controlled by the rotation drive to move through an angular stroke about a rotation axis that is spaced from and essentially parallel to the straight yarn path. The angular stroke has a starting position on one side of the path and a braking position on the other side of the path. An adjustment device varies the degree of deviation of the yarn by varying the braking position of the braking element. The distance between the rotation axis of the braking element and the straight yarn path is variable.

    摘要: During weft yarn insertion in a loom, as the end of weft yarn insertion approaches, a controllable yarn deviation brake (B), positioned between a weft feeder (M) and a warp shed (F) of a loom (D) brakes the weft yarn (Y) with a high braking force, causing a deviation of the yarn deviation brake which subsequently smooths down a tension peak of the yarn, so as to partially reduce the yarn brake deviation back towards the starting position, or position having no deviation. The same function is performed upon cutting of the weft yarn (Y). After braking and reduction of the yarn tension peak, during the weft insertion step, the braking force is reduced to a level correlated to the yarn tension which prevails up to cutting of the weft yarn (Y).
