ABSTRACT:
A roll feed apparatus for intermittently feeding a sheet-like blank material to successive work stations has a pair of sector rolls adapted to be driven by an oscillation driving device in synchronism with each other such as to clamp the material therebetween and feed the same intermittently in one direction, by virtue of a driving connection device which drivingly connects the rolls to the oscillation driving device. The apparatus further has a roll release device adapted to move the rolls away from each other when the rolls are oscillated in the directions counter to the feeding directions thereby releasing the sheet-like blank material from the clamping force.
