Abstract
The weaving machine has a weft picking mechanism which is controlled so as to adjust the picking speed of the weft yarn relative to the operating speed of the weaving machine. The means for controlling the picking mechanism receives an error signal from a comparator connected on the input side to a pick-off for detecting the arrival of a weft yarn at the weft catching station and a second pick-off for detecting the operating speed of the machine. The error signal may also be used to control a fluid type of weaving machine or may be used to control the drive of the weaving machine relative to the picking mechanism.
