AI Technical Summary

Technical Problem

In the current technology for manufacturing motor vehicle roller shutter belts, the shrinkage of plastic materials causes wrinkling, which affects product quality.

Method used

The material is tensioned in the extrusion trajectory direction using a tensioning device, and the tension is released before and after the application of the plastic material. Combined with a modular coating table and tensioning frame, this ensures that the material remains flat during cooling and curing.

Benefits of technology

It effectively reduces the risk of material wrinkling caused by plastic shrinkage, ensuring that the roller blind belt remains flat during the manufacturing process and adapts to production needs of different sizes.
