Turn-up method and turn-up mechanism

Abstract

The present disclosure provides a turn-up method and a turn-up mechanism. The turn-up method uses a pressure roller assembly to roll a sidewall along a radial direction of a tire, and the turn-up method includes: step S1: applying, by a limiting device, a pressure within a first preset range to the pressure roller assembly, so that when the pressure roller assembly moves outward along the radial direction of the tire, the pressure roller assembly abuts against the sidewall and attaches the sidewall to the side of the tire carcass; and step S2: applying, by the limiting device, a pressure within a second preset range to the pressure roller assembly, so that the pressure roller assembly moves inward along the radial direction of the tire; where a value of the pressure within the first preset range is smaller than that of the pressure within the second preset range.
