Maschine zum Schneiden von Materialbahnrollen.

摘要

A machine is disclosed for cutting a roll or log (L) of web material into a plurality of small rolls (R) which includes a unit (17) rotating about an axis (A-A) parallel to the axis of the log (L) to be cut. The unit carries a cutting blade (19) rotating about an axis (B-B) parallel to the axis (A-A) of the unit (17). Drive means (61, 63) are provided which move the cutting tool (19) into a reciprocating forward and backward motion parallel to the axis of the log (L) to be cut. At least at the time when the blade is cutting the log, the blade is moving parallel to the moving log at a translation speed substantially equal to the feeding speed of the log (L), so as to allow the cutting of small rolls (R) without stopping the log (L).
