<p>This invention is related to a driving gearwheel (1) for driving a rapier rod (2) of a weaving machine, whereby cooperation of rapier rod (2) with driving gearwheel (1) is subject to less hindrance and damage due to occurring impact load at higher operating speeds and/or larger weaving widths, in that the tooth thickness (Td) of at least one tooth (3) of the driving gearwheel (1) varies in crosswise-direction (Tb) of the tooth (3), and whereby this tooth thickness (Td) is larger in the middle area (5) than in the edge regions (7).</p> |
