DRUM FOR TIRE ASSEMBLY Russian patent published in 2018 - IPC B29D30/24 

FIELD: machine building.

SUBSTANCE: invention relates to a drum for assembling tires. Technical result is achieved by drum (1) for tire assembly, comprising a drum shaft and a peripheral surface for receiving a bus component. In this case, the peripheral surface is formed by segments (4), which are arranged to move radially between a tapered position in which the peripheral surface has a first radius, and an expanded position in which the peripheral surface has a second, larger radius. Drum (1) for assembling the tires comprises closing plates (62). Each segment (4) is provided with first portion (41) having a first support surface for supporting the tire component and with second part (42) with a second support surface for supporting cover plate (62). Each second part (42) is movable relative to the first part from the recessed position, in which the second abutment surface is recessed relative to the first radius, to an extended position in which the second support surface is elevated towards the second radius.

EFFECT: technical result is an increase in the uniformity of the peripheral surface.
