ABSTRACT:
A plurality of guides are mounted in a housing. Each of the guides is movable up and down transversely to its longitudinal direction. A plurality of sleeve carriers are slidably mounted on respective ones of the guides. A plurality of finger sleeves extend on top of the housing and are secured to respective ones of the sleeve carriers. A drive is provided for reciprocating the guides up and down with the sleeve carriers and finger sleeves and for reciprocating the sleeve carriers with the finger sleeves along said guides. A horizontal shaft is mounted in the housing for rotation on a first axis. The drive comprises a motor for rotating the shaft. A plurality of eccentric camwheels are non-rotatably mounted on the shaft. A plurality of levers are pivoted in the housing on a common second axis, which is parallel to the first axis. Each of the levers has a forward end portion, which is spaced from the second axis and constitutes one of the guides and is formed with a longitudinal groove, which receives one of the sleeve carriers. Each of the levers rides on the periphery of one of the camwheels between the groove and the second axis.
