SETTING
- For odd or unknown sizes, fold the workpiece in half, along it's
length, place on the centre line, and move the near side-guide up
to the edge of the paper.
- Having set the near side-guide, set the far side-guide to the paper.
Accurate positioning of these guides is essential for reliable and
straight feeding.
- If set too tight, poor feeding will result. If set too loose,
inconsistent perforating and scoring will result, and to a lesser
extent, inconsistent numbering too.
- With both guides set, use a single piece of your work and pass it
below the friction feed tyre.
- If the work will not fit below the friction feed tyre, loosen the nip
wheel by turning the adjustment screw.
- Now tighten the nip adjustment until a very slight drag is felt on
the paper or set. The feed bed is now ready for loading with
paper.
- The paper must be spread out (shingled), so that the top sheet
approaches the friction tyre first.
- Now place the primary feeder on to the work and lower the feed
cover.
Note 1..... The scales are for guidance only, and the side guides
may have to be adjusted to obtain a straight perforation.
Note 2..... If double or multiple sheet feeding occurs, tighten the nip
adjustment.
Note 3..... For sets to be fed open edge leading, place the glued
edge nearer to the feed wheel, instead of central. Offset
by approximately 1/3 the width of the sheet.
