Benefits

easier slit width changes due to easy

cassette exchange

significantly lower setup times than

with individual setting

exclusion of positioning errors

knife replacement during production

process

„ready for use“ replacement cassettes

cassette change by machine

operators

Module I


Benefits

optimum accuracy due to pre-adjusted

slit widths

optimised synchronism and smooth

running of knives for steady web tension

and reduction or elimination of web tear

application of crush cut knives, that have

already been used

suitable for installation in all customary

machines, also for upgrades

high user friendliness by allowing slit

widths from 4 mm

Module I


very easy slit width changes



low machine downtimes

Module II


Advantages

quick format changes


minimisation of setup time and costs

Module II-C



simultaneous top and bottom knife travel

low machine downtime

minimisation of setup time, costs and dust formation

Module II-K


Benefits

easier slit width changes due to easy

cassette exchange

significantly lower setup times than

with individual positioning

exclusion of positioning errors

knife replacement during production

time

purchase of „ready for use“

replacement cassettes

cassette change by machine

operating personnel

Module III


Benefits

optimum accuracy due to exactly pre-adjusted slit widths

optimised synchronism and smooth running of knives, i. e. steady web tension

and reduced or eliminated web tear

application of crush cut knives, that have already been used

suitable for installation in all customary machines, also for upgrades

high user convenience allowing

narrowest slit widths

“Quick Clamp“ system without tools

for fixing on a dovetail bar

Module III


reduction in machine setup times to a minimum

exclusion of manual errors

strict adherence to slitting parameters

optimum slitting quality

reduction of operating costs

Module III


specially designed for cutting multi-layer papers

suitable for slitting highest basis weights

considerably higher slitting edge quality

low dust formation

driven knives

Module IV „Twin Cut“


Benefits

fully-automatic slitting tools

utmost precision

long service life

reduction in rejects

low-dust operation

reduction in setup costs

Module IV-Q


Benefits

minimisation of setup times and costs

low downtimes


safe and easy handling

optimum slitting edge quality

minimum setup times

high positioning accuracy

control via touch screen

reduced number of rejects

higher yields

inline format corrections

Module V


Special Features

just one multi function module

almost no linear guide carriages and

linear rails are needed

reduced number of parts allowing for

easy maintenance and small

installation space

top and bottom knives are adjusted within

the blink of an eye (web must be removed

from the slitting unit)*

model „Module VI“ with simultaneous top and

bottom knife adjustment (web can remain in

the slitting unit)*

Module VI


Advantages

considerable cost reduction due to

modular design

slit widths from 25 mm possible

high positioning accuracy

easy operation

robust and approved technique

minimum positioning time

compact design, ideal for upgrading

* with model „Module VI”

web can remain in slitting unit

Module VI






Module VI


Advantages

automatic slitting tools

utmost precision

longer tool service life

reduction in rejects

low-dust operation


Module VII


constant minimum slit width of 18 mm

applications, for which no pneumatic shear cut knife

holders can be used, due to the required slit width

fully-automatic process cycle

very easy operation

highest positioning accuracy of +/- 0.15 mm per cut

quick amortisation

Module VII


long service life

reduction in merchandise loss

low-dust operation


available in manual, semi- and fully-automatic design

Module VIII
