Abstract (en)
[origin: EP4008817A1] The invention relates to a method and a device for determining a movement parameter of a gripper (3, 5) in a gripper weaving machine, wherein the gripper (3, 5) can be driven to move back and forth using a transmission part (31, 32), wherein a drive element (12, 26) rotating with a drive shaft (7) of the gripper weaving machine is drivingly coupled via a transmission mechanism (24, 25) to the transmission part (31, 32), wherein the transmission part (31, 32) can be driven by the drive element (12, 26) to oscillate between extreme transmission part positions, wherein an amplitude of an oscillation of the transmission part (31, 32) is adjustable by setting the transmission mechanism (24, 25), and wherein the method comprises the steps of determining a change in an angular position of the drive element (12, 26) when moving the transmission part (31, 32) over a defined range (Δα), and determining the amplitude of the oscillation of the transmission part (31, 32) based on the determined change in the angular position (Δ Θ1, Δ Θ2) of the drive element (12, 26).
