Abstract
In a textile machine, a device for controlling the transverse movement of a thread, such as a warp thread in a weaving machine, comprises a dragging element (2) for dragging a thread (4) moving in a transverse direction, whereby said dragging element (2) is attached on both sides to a frame (10) by means of springs (6,8). The device forms a system that oscillates freely at its natural frequency. Arresting devices (12,14) can adjustably and temporarily hold the dragging element in the extreme positions.
Claims17
Device for controlling the transverse movement of at least one thread of a textile machine, especially a warp thread in a weaving loom, with a dragging element mounted between two springs which is used to draft at least one thread, and an arresting device which can be controlled by means of a control unit and is used to temporarily arrest the dragging element in at least one extreme position, characterised by the fact that the springs and the dragging element are designed as a freely oscillating system which can be temporality arrested for an adjustable period of time by means of the arresting device and oscillates at a natural frequency f:
- ##EQU3## where m=oscillating mass and c=spring constant.
