Description

Technical Field

[0001] The utility model relates to the technical field of piercing devices, in particular to an adaptive curtain fabric piercing device. Background Art

[0002] In the production of semi-steel radial tires, the carcass cord is punctured by a licker-in roller to exhaust air. The licker-in roller is installed after the 90° cutting process lead-out station and before cutting. The roller circumference of the licker-in roller is covered with needles arranged with the same density. During the backward cutting process, the cord passes through the licker-in roller and is punctured with holes of the same density by the needles to exhaust air.

[0003] Since the thickness of the carcass joint overlap position increases and bubbles are more likely to be generated at the crown position of the finished tire, these two positions require a stronger exhaust effect. However, the density of the needles on the licker-in roller of the prior art is the same and large, which cannot meet the exhaust effect of the cord joint position and the crown carcass, resulting in frequent bubbles at the cord joint position and the crown carcass position of the tire, affecting the performance and quality of the finished tire, causing production waste and increasing the cost of tire manufacturing.
