Adjusting The Cutting-In Amount - Roland GR-640 User Manual

Adjusting the Cutting-in Amount

When you want to perform accurate adjustment of the cutting-in amount, such as
when cutting material with thin carrier paper, you can obtain good results by adjusting
the amount of blade extension.
Turn the cap portion of the blade holder to adjust the amount of blade extension.
General Guide for Amount of Blade Extension
Use the following formula as a rough guide for setting the amount of blade
extension.
Amount of blade extension = thickness of material + (thickness of
carrier paper/2)
An adjustment of 0.5 millimeters can be
made by rotating the cap one full turn.
1: Amount of blade extension
(which approximately equals
the cutting-in amount)
2: Material portion
3: Carrier paper portion
4: 1/2 of the carrier paper
