Method for obtaining one or a number of strips of a band material and a cutting die for putting the method into practice

摘要

A method for obtaining one or more strips from a band material extending in a longitudinal direction (Y), using a cutting die with 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. The cutting edges extend in a cutting line beyond the theoretic cutting start or theoretic cutting end points, or in both, which do not form part of the pattern. The cutting lines have a correcting section extending in a direction that is not parallel to the longitudinal direction (Y), to compensate for a lateral discrepancy between the theoretic cutting start and end points between two consecutive cutting operations.
