Abstract
A roll feed apparatus suited for use in automatic manufacturing machines, in feeding a sheet-like material intermittently. The apparatus comprises a main sector roll and a sub-sector roll adapted to cooperate with each other in clamping therebetween the sheet-like material and in feeding the same. The main sector roll and the sub-sector roll are operatively connected to each other through sector gears. The main sector roll is operatively connected to a rocker shaft which is adapted to be rocked in rotational direction so that the main sector roll and, hence, the sub-sector roll are made to rock as the rocker shaft makes a rocking rotation. A connection device is provided for operatively connecting the main sector roll to the rocker shaft in such a manner that the rocking angle of the main sector roll for a given rocking angle of the rocker shaft is changeable. The apparatus further has a roll release device adapted to release the sheet material from the clamping by the rolls when the rolls are reversed, and a braking device for fixing the sheet material against movement during reversing of the rolls.
