Abstract

The invention discloses a cutting method which is used for cutting a tire sidewall and inside liner composite piece in the tire production process. The cutting method comprises the steps of fixing the sidewall and inside liner composite piece, and conducting cutting by forming an angle with tire body cord threads. According to the cutting method, the cutting direction of a cutter is arranged to form the angle with the tire body cord threads, so that the occurrence probability of the condition of 'sparse thread' of the tire body cord threads is lowered.

Description

technical field [0001] The present application relates to a tire production method and device, in particular to a cutting method and device for tire sidewall and inner liner composite parts. Background technique [0002] In the process of tire production and use, "thin thread" is a relatively common symptom, which is directly related to the economic interests of the manufacturer and the life safety of customers. Extensive anatomical analysis of "thin-thread" tires revealed that poor joint quality of the sidewall and inner liner during tire building was the main cause of the above-mentioned defects. Therefore, controlling the joint quality of sidewalls and inner liners has become a common goal in the field of tire manufacturing. [0003] The direction of the sipes of the existing cutting device is perpendicular to the guiding direction of the composite parts of the sidewall and the inner liner. Therefore, after cutting, the joint line between the sidewall and the inner line...
