Abstract

A main roll and a sub-roll of a sheet material feeding apparatus interpose therebetween a sheet material to intermittently feed the same to a press apparatus. A roll clearance is adjusted according to a sheet thickness by displacing the main roll up and down. A release device that temporarily releases a sheet material having been interposed by the both rolls just before the sheet material is subjected to press working by the press apparatus includes a sub-roll guide that can move up and down together with the sub-roll, a rectilinear cam, and cam followers for engagement with a cam surface of the rectilinear cam, and the release device moves the rectilinear cam axially of the sub-roll in synchronism with the operation of the press apparatus to thereby displace the sub-roll up and down through the cam followers and the sub-roll guide.
