Abstract
A ribbon needle weaving loom including an electromechanic actuator for driving the weft thread insertion needle. A control device is provided and the actuator is configured—in co-operation with the control unit—in such manner as to allow preselection of the end position of the weft thread insertion needle at weft-insertion and of the position with retracted weft-insertion needle, and/or the starting time point of the motion of the weft-insertion needle and/or—the instantaneous speed of the motion of the weft-insertion needle, at least within a certain range. The electromechanic actuator is configured as rotary actuator or a linear actuator.
Claims12
A ribbon needle weaving loom comprising a weaving point, at which warp threads are interweavable to each other by means of at least one weft thread, a device for feeding the warp threads, a device for feeding the at least one weft thread, further comprising a shed forming device for forming a shed from the warp threads, further comprising at least one weft thread insertion needle for inserting a weft thread loop into the shed, and comprising a reed for stopping the weft thread loop, wherein
- an electromechanic actuator for driving the weft thread insertion needle and a control device are provided,
- characterized in that
- the actuator is configured in such manner as to allow preselection, by means of said control device, of at least one of the following measures:
