Abstract
The invention is an improvement in an apparatus for developing sheets of diazotype copying material by the semi-dry process and includes at least two rotatable rolls being biased together with a gap between them for passage of the sheets of diazotype material, with an additional force being exerted on at least one of the rolls which force transfers a plane of deflection of one of the rolls to a position outside of a principal plane in which axes of the rolls are located in such a manner that a first line of intersection between the plane of deflection and the shell of the aforesaid one roll, starting from which line of intersection the deflection is directed toward the roll axis, extends in front of the gap, when viewed in the rotational direction of the roll, first guides to bring sheets of diazotype copying material into contact with the roll at a first transition line between the first line of intersection and the gap, and second guides to lift the sheets off of the roll behind the gap at a second transition line located before a second line of intersection between the plane of deflection and the aforesaid shell of the roll, starting from which second line of intersection the deflection is directed away from the roll axis.
