METHOD AND DEVICE FOR ADJUSTMENT OF TIRE BUILDING DRUM CHARACTERISTICS Russian patent published in 2024 - IPC B29D30/24 B29D30/26 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a method and a device for controlling characteristics of a tire building drum The method is carried out using a device for adjusting the characteristics of a tire building drum, which comprises drive unit (41), transmission unit (42) and a variable diameter element (43), which are connected in series, drive unit (41) comprises drive element (411) and output element (412). Method includes steps of actuating output element (412) in axial direction by means of drive element (411) in accordance with the size of the tire to be processed, with displacement to retracted position or intermediate position and providing possibility of arrangement of element (43) with variable diameter at minimum diameter or intermediate diameter. After gluing the material or installing the steel ring, output element (412) is actuated for movement into the expansion position by means of drive element (411) and changing diameter of variable diameter element (43) by maximum diameter. Then, after processing is completed, output element (412) is actuated by means of drive element (411) to move into retracted position, diameter of variable-diameter element (43) is reduced and treated tire is removed.

EFFECT: change of inch classes of mechanical drums for tire assembly without expenditures of time and labor, processing of tires of multiple inch classes, provision of time and labor saving, as well as increased efficiency of processing and reduced production costs.
