Daco LS350 Label Sheeter

The Daco LS350 for the sheeting of labels and tags from flexographic and digital label presses. The fully servo-driven sheeter utilises a rotary sheeting tool to produce sheeted labels quickly and it is significantly faster than guillotine based systems.

Benefits

The Daco LS350 label sheeter can sheet to register labels and light tag stocks for clients wishing to convert material from digital or flexographic label presses. The machine is servo driven and uses just one sheeting cylinder to produce sheet lengths from 50mm up to 1400mm (2” – 55.11”).  The LS350 sheeter is significantly faster than guillotine based systems.

The Daco LS350 label sheeter is quick to set up through the use of innovative software and intuitive touch screen control, which allows the operator to be in production with the absolute minimum of setup waste.

The large 700mm (27.5″) unwind has an Merobel electronic brake and taper tension control.  An optional upgrade to a U350L 1m (40”) unwind module will keep roll changes to a minimum.
