Abstract: The feeding mechanism serves to intermittently feed stock to a processing machine and comprises a rocker lever having at its outer end an arcuate surface shaped according to an arc of a circle, crank drive comprising a crank which is operatively connected to said rocker lever, said crank drive being operable to impart an oscillation to said rocker lever, a clamping roller adapted to cooperate with said arcuate surface and forming a feeding clamp therewith, a retaining clamp for holding said stock in position, and control means for cyclically opening and closing said feeding clamp and retaining clamp in alternation.

Abstract: A machine for processing stock by using aram is disclosed. The machine has a frame structure with a ram-guiding frame therein. The ram-guiding frame is symmetrical in cross-section and has forward and rear members which leave free a first space through which tools are accessible. The members have end side portions which leave free a second space for feeding stock. Vertically adjustable guides for guiding the ram are detachably connected between the ram and the end side portions of the forward and rear members.

Abstract: The feeding mechanism serves to intermittently feed stock to a processing machine and comprises a rocker lever having at its outer end a gear segment, a crank drive comprising a crank which is operatively connected to said rocker lever, said crank drive being operable to impart an oscillation to said rocker lever, a feeding clamp comprising first and second, reversibly rotatable, toothed feed rollers arranged to mesh with each other when said feeding clamp is closed, said first feed roller being in mesh with said gear segment, a retaining clamp for holding said stock in position, and a cam operated control linkage for cyclically opening and closing said feeding clamp and retaining clamp in alternation.
