Abstract
The invention relates to a process for the fabrication of a drum made of kraft paper according to which a sheet of kraft paper is rolled on a mandril so as to constitute a rotating cylindrical tube. The end of the tube which forms the bottom is rolled with more than one turn and receives a disk which constitutes the bottom of the drum. The disk is then placed on the ridge (8) formed by the rolled edge, and a retaining collar (10) is placed around the tube. The collar is then tightened to clamp the disk (3A) onto the tube.
