摘要： A measuring feeding device for an air or water jet weaving machine having a stationary storage body for a yarn store consisting of yarn windings wound on tangentially in a predetermined winding direction, from which yarn store the yarn can be withdrawn overhead of the storage body. The device includes a stop element associated with the storage body which can be moved by means of a control unit between a stop position blocking withdrawal of the yarn and a release position allowing withdrawal of the yarn, and a yarn clamping device having a displacement drive and a brake shoe which is adjustable between a lifted position and a yarn clamping position. The braking shoe, in the yarn clamping position is positioned behind the stop element in the winding direction and is maintained in the yarn clamping position after a stroke of the stop element into the release position.

摘要： A thread feed system having a measuring feeder, a supply bobbin supplying thread to the measuring feeder and a textile machine which withdraws the thread from the measuring feeder so as to perform a weaving operation. The measuring feeder includes a storage drum and a winding element which removes the thread from the supply bobbin and winds the thread onto the storage drum. A control device is provided for monitoring the operating conditions of the thread system so as to identify increases in thread tension. The control device is operatively connected to an auxiliary conveyor device having a drivable friction roll which is frictionally engaged with the thread between the supply bobbin and the storage drum. The auxiliary conveyor device is operable so as to provide an increased frictional action on the thread so as to advance the thread at an increased rate to the storage drum so as to preparatorily counteract the thread tension increase and eliminate short picks of the thread in the textile machine.

摘要： According to a method and apparatus for controlling the insertion process of a weft yarn, the weft yarn is temporarily exposed to a braking friction and the yarn tension is mechanically picked-up. In order to prevent the friction from having a disturbing or damaging effect on the yarn, the yarn tension is only temporarily picked-up during certain phases of the insertion process, in order to derive information from the tension curve that is useful for the control of the insertion process. In a power loom, in particular a jet, rapier or gripper shuttle loom, a tension sensor for sensing the tension of the weft yarn can be switched during insertion between its sensing position and a passive position in which it does not touch the weft yarn. Preferably, the tension sensor is integrated in the insertion brake or even forms the braking element itself.
