ABSTRACT:
A star wheel is formed with angularly spaced teeth and intervening pockets and is indexed through one step each time a rotatable actuating pin enters one of the pockets. One of the teeth has a significantly greater angular width than the other teeth and has a tip which is periodically engaged by the pin to stop rotation of the pin. To reduce shock resulting from the pin striking the tip of the wide tooth, a slot is formed in the wide tooth to cause part of the outer end portion of the tooth to be resiliently cantilevered on the remaining portion of the tooth and to enable the outer end portion to flex inwardly when the pin moves into engagement with the tip.
