9.3.8.1 Preprinted marker

In some applications, processing multi-ply material spreads preprinted full size mark-
ers that are laid on the top of the material are used to identify cut components (see
Figs 9.17 and 9.18). This process is not efficient as marker printing consumes addi-
tional time and the paper and, in the cutting process, the markers are cut and wasted.

9.3.8.2 Off-load screen/display
Off-load screen on which the full marker or only the part of the marker already cut and
placed in the take-off zone is used. On the screen, the cut components are identified
with a numerical or textual annotation or by colour – the components of different
orders/sizes are showed in different colours. Off-load display can be mounted cen-
trally above the off-load table of the cutter or placed next it. The on-screen off-loading
assistance simplifies bundling and reduces the risk of errors in the process. On the
touchscreen, an operator can also mark the cut components with faults that require
1
recutting (e.g. cutter Z1 by Gerber ).
9.3.8.3 Overhead projector
An overhead projector highlights components or a group of components to be col-
lected (in different colour) or displays perimeters of the components, patterns or texts
on the components at a take-off area of the cutter (see Fig. 9.19). The written or nu-
merical annotation and the shape of the components clearly identify cut parts as the

operator unloads them. (‘cut part identification system’ by Gunnar , Topcut Bullmer ,

‘Cut Collect Assistanť by Gemini , video projection system by Elitron , laser projec-
1
tors by Gerber , and others). Using the annotation feature, the cut components can also
be labelled manually in the take-off zone of the cutter.
