Abstract
A roll feed apparatus comprises a main roll (4) and a subroll (8) adapted to cooperate with the main roll to feed a flat workpiece (7) in a clamped state on a step-by-step basis. The main roll is mounted on an output shaft (2) of an intermittent motion mechanism (3) to be intermittently rotated in one direction. The subroll has a rotation-transmission roll (8a) disposed at one axial end of the subroll and is rigidly mounted on a subroll shaft (6) which is rotatably supported in a roll housing (5a) through an externally rotatable eccentric flange (10), and a workpiece-engaging roll (8b) supported by the rotation-transmission roll and surrounding the subroll shaft. The rotation-transmission roll has a peripheral surface which makes rolling contact with the main roll for transmitting rotation, and is movable toward and away from the main roll to adjust contact pressure between the main roll and the rotation-transmission roll upon rotation of the eccentric flange. The workpiece-engaging roll is rotatably supported within a roll holder which is movable, together with the workpiece-engaging roll, toward and away from the main roll to adjust the amount of nip between the main roll and the workpiece-engaging roll. See FIGS. 2-6.
