ABSTRACT:
A solenoid clutch mechanism for providing intermittent rotation of a feed roller in a web feeding apparatus. The clutch mechanism includes a solenoid having a reciprocable plunger connected to a pivotable arm in abutment with a cam mounted on a driven shaft. The driven shaft is drivingly connected to the cam by means of an overcenter coil spring. Coupled to the cam is a gear train in driving relation to the feed roller. The driven shaft will rotate relative to the cam as long as the arm is in abutment with the cam. Upon retraction of the solenoid plunger the arm is raised permitting the cam to rotate by virtue of the spring drive connection to the driven shaft in turn causing rotation of the gear train to drive the feed roller to advance a web.
