Abstract
A method of forming a rotatable cutting shaft member having a longitudinal axis and a plurality of axially spaced cutter elements for shredding substrates that are inserted in an opening in a housing of a shredder, in which the shaft member is a part of a shredder mechanism that is activated by a motor in the housing, is provided. The method includes turning opposing end portions of at least a longitudinal section of the rotatable cutting shaft member relative to one another in opposite directions about the longitudinal axis so as to twist at least the longitudinal section of the rotatable cutting shaft member to a predetermined helix angle; and mounting the plurality of axially spaced cutter elements on the rotatable cutting shaft member. The predetermined helix angle orients the plurality of axially spaced cutter elements on at least the longitudinal section in a helical arrangement.
