Abstract
Method for introducing a weft thread in a weaving machine which comprises a device (10) for introducing a weft thread (3, 64), which method comprises adjusting a control parameter and adapting the number of insertions for determining the mean deviation of an insertion parameter. Weaving machine which comprises a device (10) for employing an abovementioned method.
Claims9
Method for controlling insertion parameters of weft threads in a weaving machine that includes a device for inserting weft threads and a control that adjusts weft thread insertion control parameters, comprising:
- during weaving, measuring arrivals of a plurality of inserted weft threads and determining on the basis of such measured arrivals the deviations between actual arrivals and desired arrivals of the inserted weft threads;
- determining on the basis of a selected number of determined deviations a mean deviation value of the weft thread insertions;
- adjusting a weft thread insertion control parameter via the control as a function of said mean deviation value;
- and
- adjusting the number of determined deviations used to determine said mean deviation value as a function of variations of determined deviations.
