Abstract
The building drum includes a support (20), a central shaft (30) and an outer circumferential surface coaxial with the axis of rotation of the drum. The building drum also has a principal cylindrical surface (100) axially bounded by a shoulder (101) extended by a lateral protuberance (102) for receiving the products which have to be assembled. Several segments together define the principal cylindrical surface, and those segments are being divided into first and second groups of adjacent segments (103a, 103b) mounted so as to move between a first position in which they are circumferentially juxtaposed and a second position in which the adjacent segments are radially offset. Several adjacent elbow levers (140) form the shoulder (101) and the protuberance (102) in the expanded position of the drum and each elbow lever (140) is mounted with articulation on the segment (103a, 103b) and on the support (20).
