Abstract
In order to better configure a ribbon needle weaving loom—in particular for applications in which there are particular requirements for the setting of the weft thread tension—it is proposed to provide an electromechanic actuator for driving the weft insertion needle and a control device. Thereby, the actuator is configured in such manner as to allow preselection, by means of said control device, of the end position at weft insertion and of the position with retracted weft insertion needle and/or preselection of the starting time point of the motion of the weft insertion needle and/or preselection of the instantaneous speed of the motion of the weft insertion needle, within a certain range.
Claims20
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 weft thread insertion needle beim weft insertion and die Position bei the actuator is configured in such manner as to allow preselection, by means of said control device, of the end position of the weft thread insertion needle at weft-insertion and of the position with retracted weft-insertion needle and/or preselection of the starting time point of the motion of the weft-insertion needle and/or preselection of the instantaneous speed of the motion of the weft-insertion needle, at least within a certain range.
