A thread stretching device for a weaving machine, especially an air jet weaving machine, includes a thread gripper () for gripping the weft thread () as a device for stretching a weft thread inserted into a shed. A mechanism () for deflecting the weft thread is arranged upstream of the thread gripper, relative to the weft thread transport direction.

Device and method for stretching

A thread clamp for a weaving machine includes a clamp having at least two clamping parts between which a thread may be clamped and an actuator arranged to move the clamping parts between clamping and unclamped positions. The actuator is arranged to operate the clamp so that it moves at least in one direction by a negative fluid pressure. The actuator may be formed as a small piston that may be actuated both by positive pressure and negative pressure to move the clamp between clamping and unclamped positions.

Thread clamp for a weaving machine

A device for inserting weft threads in an airjet weaving machine including at least one main blower and a respective thread clamp associated with the main blower. The thread clamp is constituted of an element configured in a modular form. Such modular form enables several such elements to be assembled in a modular configuration, including one on top of another. Pneumatically actuated elements are used to engage and disengage the thread clamps whereby the thread clamps may be engaged or disengaged by pressure and vacuum supplied through a single supply conduit. A method for inserting weft threads in the shed of an airjet weaving machine includes holding each weft thread at least temporarily in a thread clamp that moves with the sley of the weaving machine and using a thread tensioner outside the shed at a location between the thread supply and the thread clamp. A further method of inserting weft threads includes supplying the main blower temporarily with a lower pressure before insertion of the weft thread by the main blower when the thread clamp holding the thread is opened.
