1. A method for aligned portions of a carrier blank while folding said carrier blank into a folded carrier comprising:

  • providing a relatively flat carrier blank having in a partially folded condition at least a first portion and a second portion joined together by a fold line with said first and second portions having oppositely facing generally planar surfaces when folded around said fold line so that said first and second portions are in superposed relationship;

    forming an abutment tab in said first portion of said carrier blank, said abutment tab comprising at least one linear cut line and at least one fold line;

    moving a portion of said abutment tab to a position projecting out of said generally planar surface of said first location to form a linear abutment edge from said linear cut line;

    folding said carrier blank so that said first portion of said folded carrier blank has a first linear edge;

    folding said carrier blank so said second portion of said folded carrier blank has a second linear edge adapted to be positioned in superposed and parallel relationship to said first linear edge;

    providing a linear abutment edge on said second portion, said linear abutment edge in said second portion being parallel to said linear cut line;

    said linear abutment edges in said first and second portions being parallel to said first and second linear edges;

    producing relative folding movement between said first and second portions so that said linear abutment edge on said second portion and said linear abutment edge of said abutment tab are moved into contacting relationship; and

    continuing said folding movement so that said linear abutment edges guide said first and second linear edges into a superposed and parallel relationship.
