By pressing the pre-dispense key (
1
), half cycles of the labelling
process can alternately be released, provided that there is a print job.
1(st) half cycle
Pressing the key will release the print of one label. At the same
moment the vacuum at the pad as well as the supporting air (blow
tube) are switched on. After the label has been printed and picked up
by the pad, the supporting air is switched off.
2(nd) half cycle
Pressing the key will drive the swing cylinder to move the pad down
into the labelling position. The sensor signals when the labelling
position is reached.
Following, the vacuum is switched off and the label is placed onto the
product by blowing. Then, the swing cylinder is driven to move the pad
back into the starting position.
