ABSTRACT:
A roll feed apparatus having a first roll and a second roll for intermittently clamping therebetween and feeding sheet material. An adjusting device is provided for adjusting the gap between the first and second rolls and includes a pivot member adapted to cause, when it pivots, the first roll to more towards and away from the second roll. First and second braking members temporarily fix the sheet when it is unclamped from the rolls. The second braking member is carried by a braking position adjusting arm disposed between the pivot member and the path of feed of the sheet. The adjusting arm is pivotally carried by the pivot member and arranged such that an imaginary plane connecting the portions of the first roll and the second braking member closest to the path of feed of the sheet is moved, when the pivot member pivots over a predetermined angle, substantially in parallel with the path of feed of the sheet.
