ABSTRACT:
A table supports a cardboard file unit body as it is manually slid edgewise forwardly, engaged against a fixed but adjustable side edge guide, into engagement with a fore-and-aft movable front edge guide and an air microswitch thereon that actuates a punch mechanism. After punch operation, the front edge guide moves forward, bringing the punched portion of the body between the wings of a metal tab waiting at a peening station. Arrival of the front edge guide at its forward position trips another air microswitch to actuate a tab peening mechanism. The tabbed body is then manually withdrawn rearwardly and a new tab is automatically fed rearward to the peening station from a stack of tabs in front of that station. The punching and peening mechanisms, front edge guide and tab feed slider are actuated pneumatically.
