METHOD AND DEVICE FOR ADJUSTING AXIAL SIZE OF CENTRAL DRUM ASSEMBLY AND DRUM FOR TIRE BUILDING Russian patent published in 2024 - IPC B29D30/24 B29D30/26 

FIELD: control and measuring equipment.

SUBSTANCE: group of inventions relates to an adjustment method and a device for adjusting the axial size of a central drum assembly and a tire assembly drum. Method is carried out using a device for adjusting the axial size of the central drum unit, which comprises first central drum unit (10), second central drum unit (20) and an intermediate central drum unit (30) located between the first central drum unit (10) and the second central drum unit (20). Method includes: moving at least one of the first central drum unit (10) and the second central drum unit (20) towards each other, wherein the first central drum unit (10), the second central drum unit (20) and the intermediate central drum unit (30) intersect and retract relative to each other so as to reduce the length of the central drum assembly, movement of at least one of the first central drum unit (10) and the second central drum unit (20) in the direction from each other, wherein first central drum unit (10), second central drum unit (20) and intermediate central drum unit (30) intersect and extend relative to each other so as to increase the length of the central drum assembly.

EFFECT: achieving expansion and contraction of the central drum unit three times so that the range of the adjustable axial size of the central drum structure will be greater, range of coverage of central drum unit will be expanded, and maximum size of central drum unit will be increased, which thereby reduces the number of replacements of gear units and significantly increases efficiency of production.
