The one roller 19 thus transports the copy paper along the guide plates 21a, 21b and 22, while the second roller 20 ejects the template from the machine.

When the overlapping paper sheets enter between the rollers 13 and 14 becomes the leading edge of the Copy paper opposite the leading edge of the original due to the rotating at a higher peripheral speed Roll 13 pushed forward a little. If now the protruding leading edge of the copy paper against the arm end 17a of the Lever 17 pushes against its tension, the lever is pivoted around the pin 18 to the right and the lock between the curved part 17b of the other lever arm and the cutting disk 16 canceled. The leading edge of the Copy paper is around the pivot 15 along the Guide plates 21a, 21b out, engaging the locking claw 16a of the cutting disc 16 and then through the Relle 25 to the development facility will. The one slightly behind the leading edge of the copy paper

The publishers are then driven by the rotating roller 20 in the ejected from the machine in the direction shown with arrows.

A curved guide plate 24 is also provided, which follows the circumference of a hollow 6a, with the aid of which the template can be reinserted into the guide 8 of the template feed device by moving the guide plate around its pin by actuating it from the outside by approximately 90 ° rotates · This allows a large number of cuttlefish to be produced from one original sheet.

In the direction of movement of the copy paper, a Transpert re heap aar 25 is arranged on ämx rare wall. The parts from which rolls 13 and 14 started up to the transport roll)! . 25, form the automatic separation device IV
