Blade cut


At blade cutting the web is slit with an industrial razor blade for further processing.



For blade cutting rigid films and paper is suitable up to a thickness of max. 0.2 to 0.3 mm and soft films up to max. 0.4 mm.

Cutting of the web can be done in the air, where the web is supported short before and behind the cutting point by idler rolls to prevent a movement of the web out of the cutting area of the blade. Or cutting is done within a grooved shaft which supports the web. At continuous running machines also double or multi-blade holders can be used to avoid a stop of the production for changing of worn blades.
