Abstract
This invention is related to a drive pinion (1) for actuating a rapier rod (2) of a weaving machine, whereby interaction of rapier rod (2) with drive pinion (1) is subject to less hindrance and damage due to occurring impact load at increased operational speeds and/or larger weaving widths, in that the tooth thickness (Td) of at least one tooth (3) of the drive pinion (1) varies in widthwise-direction (Tb) of the tooth (3), and whereby this tooth thickness (Td) is larger in the middle area (5) than in the fringe areas (7).
