RLS DIE – die cutting machine

LESKO RLS DIE

LESKO RLS DIE is the optimally constructed, ideal die cutting machine for constant, long-term work, even 24/7.

This type of machine can be used to:

die cutting,
confectioning on the specified number of labels or roll length,
slitting.

Our die cutting machines type RLS DIE are dedicated to work with printed and pure materials.

Thanks to long-term experience we can offer you a machine with the latest generation die cutting unit.

Optimum structure of die cutting unit (anvil supported by resistance shaft ) ensures stability of parameters for many years.
