Abstract

A core tube (1) for use as a reeling core of a paper roll, on which is formed at least one weakened line (2), by perforation, and extending substantially from end to end of said core tube. A method of making the core tube is also disclosed, in which the weakened line is formed by pressing a disc-like rotating perforation blade (11, Figure 3) through the core tube against a counter roller placed within the tube. <IMAGE>
