ABSTRACT:
An assembly machine has a frame defining at least one work station, a transfer mechanism for feeding a succession of workpieces one at a time through the station, and at least one tool at the station movable between an operative position engageable with the workpiece in the station and a retracted position out of engagement with the workpiece in the station. A push-pull operating element has an outer end connected to the tool and an inner end connected to a cam carried on an output of a drive mounted on the frame for displacing the tool between its positions synchronously with feeding of the workpieces through the station. A pneumatic spring mounted on the frame is braced against the tool and has a compartment pressurizable to urge the tool into the operative position. The back compartment is continuously pressurized with a gas under a generally constant pressure.
