Abstract
A pick device is incorporated in a weaving machine for the shuttles. The device comprises an accumulator for a working medium which can be filled into and emptied out of the accumulator and a pick-executing unit is incorporated, which performs its pick operation upon actuation by the working medium during emptying of the working medium out of the accumulator. A regulating member varies the effect of the working medium on the unit as a function of signals received for a controlling unit, thereby providing a predetermined pick force to the pick-executing unit.
