Abstract
A roll frame which has two arched rolls, the radii of which can be adjusted by an adjustment crank. Adjacent material formats, such as printing plates or printed circuit boards, are separated parallel to each other transversely to the running direction by an individualizing interval when running through the feed nip between the two arched rolls. The individualizing interval is directly proportional to the format length and the format width of the printing plates or printed circuit boards, and indirectly proportional to the square root of the difference of the squares of the arched roll radius and half the format width.
Claims15
Apparatus for separating adjacent material formats comprising:
- a pair of arched rolls each having a roll radius and being arranged one above the other as a pair of squeeze rolls having a nip therebetween, the formats running in a running direction through the nip of the rolls;
- and
- means for adjusting the radii of the rolls for achieving an interval (2t) between the formats transverse to the running direction of the formats which includes a crank for moving the rolls simultaneously to arc-adjust the rolls with the same curvature.
