Method for turning-up tire structure part on tire structure drum for manufacturing green tire, involves driving turn-up rollers along curve on carcass, so that tire structure parts are rolled-up on carcass to complete green tire production

摘要

#CMT# #/CMT# The method involves positioning a tire carcass (11) on a tire structure drum (16), where the tire carcass is held by core clamping segments (9). Tire structure parts (8) laterally projecting into the core clamping segments are turned-up in radial direction (17) over expanding movement of roller levers (4). Multiple turn-up rollers (3) are driven along a predetermined turnover curve on the tire carcass, so that the tire structure parts are rolled-up on the tire carcass to complete a green tire production according to an existing manufacturing process. #CMT#USE : #/CMT# Method for turning-up a tire structure part on a tire structure drum for manufacturing a green tire. #CMT#ADVANTAGE : #/CMT# The turn-up rollers are driven along the predetermined turnover curve on the tire carcass, so that the tire structure parts are rolled-up on the tire carcass to complete the green tire production according to the existing manufacturing process, thus turning-up the tire structure part in a simple manner. The method enables ensuring a precise positioning of the roller levers below the protruding tire components by the movement of the roller levers in guide grooves. The method enables utilizing a very small space on the tire structure drum by a high impact mechanism, so that space on the tire structure drum can be minimized. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a radial sectional view of a tire structure drum in an initial stage of a tire structure part turning-up process. 3 : Turn-up rollers 4 : Roller levers 8 : Tire structure parts 9 : Core clamping segments 11 : Tire carcass 16 : Tire structure drum 17 : Radial direction.
