Abstract
A thread stretching device for a weaving machine, especially an air jet weaving machine, includes a thread gripper (22) for gripping the weft thread (10) as a device for stretching a weft thread inserted into a shed. A mechanism (23) for deflecting the weft thread is arranged upstream of the thread gripper, relative to the weft thread transport direction.
Claims23
An apparatus for stretching a weft thread inserted into a weaving shed of a weaving machine, for example an air-jet weaving machine, comprising a thread clamp actuatable by means of a control unit arranged to clamp the weft thread, upstream of which relative the weft thread transporting directions, a device is provided actuatable by said control unit for deflecting the weft thread.
A method for stretching a weft thread after its insertion into a weaving shed of a weaving machine, for example an air-jet weaving machine, comprising clamping the weft thread at least approximately at the end of the insertion on the side of the shed opposite the insertion side and maintaining the inserted weft thread in tension by deflection of the weft thread until it is beaten up.
