GBC Auto 50 MBM Crease - Manual (Page 5)

Setting Side Lays
There are two side lays on the machine which sit at each side of the paper on the infeed
section. Their purpose is to guide the paper under the feed gate and into the feed rolls
accurately, to ensure a square crease is made across the document. They also supply air to
the underside of the paper stack, by way of thin slots, in order to make the paper “float”
before the bottom sheet is vacuum fed away under the feed gate.
On the CM Auto 50 there is also the capability to adjust the lays out of squareness to
accommodate for non square crease lines, although this adjustment is minimal.

Firstly, ensure that the squareness adjustment is set to its central position by aligning the
two marks on the machine bed.
The right hand side lay has four location positions. By removing the thumbscrews at the
feed gate end, the lay may be extracted from one slot and repositioned in another, using
the thumbscrew to secure it. This position must be selected with the paper size being fed
in mind, in order to keep the feed gate as central as possible to the paper centre line.
Once the right hand lay is in position, loosen the two thumbscrews at either end of the left
hand side lay and with a single sheet in the machine, push it across to the correct width of
document. The lays should not pinch the document and the paper must sit on top of the
protruding edge at the base of the lay. Secure the thumbscrews when in position.
