Roller blind bottom hem pocket welding refers to the process of using heat to fuse or weld the bottom hem pocket of a roller blind together. The bottom hem pocket is the fabric sleeve or pocket located at the bottom of the roller blind that holds the weighting bar.
During the welding process, a hot air gun is used to heat the material of the bottom hem pocket, causing it to melt and fuse together, creating a durable seal. This process can be used with various types of materials, including PVC, polyester, and other synthetic fabrics.
Welding the bottom hem pocket can help to prevent the weighting bar from slipping out of the pocket, providing a secure and stable base for the roller blind. It can also help to improve the overall appearance of the blind by creating a neat, clean finish at the bottom.
