ABSTRACT:
The mechanism makes it possible to control the advance of operating units (9, 9') in a much simpler fashion than known mechanisms which use cams or long tappets. It comprises the following: a plurality of toothed wheels (3), one for each station (9, 9'), all of them activated by a single toothed belt (1) through one or more motors (4) which can be asynchronous. Each toothed wheel (3) controls the following: one upper shaft (4), one endless screw (6), one companion wheel (7), one roller (5), and one lever (10, 18) for the advance of the upper operating units (9). At the same time it controls the following: a lower shaft (4'), an endless screw (6'), a companion wheel (7'), a roller (5'), a lever (10', 18') for the advance of the lower operating unit (9').
