A process for obtaining one or more strips of a web material and a cutting die for the implementation of the method

摘要

A method for obtaining one strip or a number of strips from a band material which extends in a longitudinal direction (Y) which comprises using a cutting die which has at least two cutting edges, there being at least two theoretic cutting start and end points on each one of the cutting edges which determine a predetermined cutting pattern therebetween, wherein said cutting edges are extended in at least one cutting line beyond the theoretic cutting start or theoretic cutting end points, or in both, which do not form part of the pattern, said cutting lines comprising a correcting section which extends in a direction that is not parallel to the cited longitudinal direction (Y), being intended to compensate for a lateral discrepancy between the theoretic cutting start and end points between two consecutive cutting operations.
