ABSTRACT:
A roll feed apparatus for feeding a sheet material successively to different working stations. The apparatus includes an oscillation driving device, a main sector roll integrally carried by a main roll shaft and adapted to be oscillatorily driven by the oscillation driving device, and a sub-sector roll integrally carried by a sub-roll shaft extending in parallel with the main roll shaft. The sub-sector roll is adapted to cooperate with the main sector roll in clamping a sheet material therebetween and feeding the same. The apparatus further has a driving connection mechanism for drivingly connecting the main sector roll and the sub-sector roll to each other in such a manner that, when the main sector roll is rotated in one direction by a predetermined angle, the sub-sector roll is rotated in the opposite direction substantially by the same angle as the main sector roll, and a roll release device adapted in the opposite direction substantially by the same angle as the main sector roll, and a roll release device adapted to cause a relative movement between the main sector roll and the sub-sector roll, and a roll release device adapted to cause a relative movement between the main sector roll and the sub-sector roll away from each other when the sector rolls are rotated in the directions opposite to those for feeding the sheet material, thereby to release the sheet material from the camping force exerted by the sector rolls.
