7. ADJUSTMENT OF MACHINE AND FEEDING TABLE
7.1 Introduction
Electric automatic creasing and perforating machine serves for final processing of graphic material of the
width up to 450 mm. Creasing allows easy folding of the paper and that’s why it is convenient to use the
machine in combination with a folding module. No-waste perforation enables you to tear the paper easily.
The default setting has been done for all types of tools. To change the function of the machine it is
necessary to exchange the tool (placed by the manufacturer into the waste drawer – 13). Unplug the
machine, take out the tool (9) and replace with the required tool. To replace the cutters in the tools loosen
the tool screws (32, 33, 34, 38). Replace the cutter and fit the tool back. Tighten the tool screws (32, 33)
lightly. Then place the tool into the machine and perform a trial stroke to ensure the cutter and the tool base
(24) are parallel. Other settings are done through the display unit –

7.2 Adjustment of Table
Place the angle regulation screw (17) in to the initial position, so that the front side guides (3) are
perpendicular to the tool. The initial position of the angle regulation screw (17) can be checked on the skew
indicator of the front side guide (30) – the back movable part of the indicator must be vertical and aligned
with the cross mark. Set the table thrust regulation screw (14) to minimum thrust. Ready the table into the
lower locked position. Lock the table by pressing the right and left edge of the table simultaneously with
your palms (fig. 6).

The table automatically locks in the lower position. Tilt the paper brakes (7) outward. Loosen the locking
bolts of the side guides (21). Set the front side guides (3) approximately for the paper format size, so that
the position of the sheet is symmetrical with the centre of the feeding table. Rulers on the feeding table
serve for exact adjustment of the side guides (3). Place the magnetic strips (5) on the feeding table
between the front side guides (3) – two or four strips (5) according to the paper format. The magnetic strips
(5) prevent the paper on the feeding table from corrugating and improve the feeding function (fig. 7).
