Claims

[Scope of utility model registration request]

a frame, a main roll rotatably supported at both ends by the frame, a support shaft supported by the frame with its axis parallel to the axis of the main roll, and a support shaft rotatably supported at both ends of the support shaft. a pair of sub-roll arms supported by;
a sub-roll whose both ends are rotatably supported by the pair of sub-roll arms, and which intermittently conveys the plate material in cooperation with the main roll;
A set spring biases the sub-roll toward the main roll, and a set spring is rotatably provided on the frame, and is driven to rotate when the main roll and sub-roll stop conveying the plate material, so as to move the sub-roll arm toward the support shaft. A feed roll device including a cam shaft that rotates around a cam shaft and moves the sub roll in a direction away from the main roll against the biasing force of the set spring, wherein both ends of the support shaft are respectively attached to the frame. A pair of support pieces rotatably supported are provided so as to be movable in a direction in which the sub-roll approaches and separates from the main roll, and movement of the support pieces in the direction in which the sub-roll approaches and separates from the main roll is prevented between the support pieces and the frame. a fixing means is provided, an auxiliary spring is provided between the frame and the sub-roll arm to urge the sub-roll arm toward the camshaft, and the support shaft is attached to either the sub-roll arm or the support piece. A feed roll device characterized in that it is movable within a predetermined range in the direction of approaching and separating from the feed roll device.
