[0002] Automotive weatherstripping is an important component of automobiles. It fills gaps between body components, providing shock absorption, waterproofing, dustproofing, sound insulation, and decorative effects. High-quality weatherstripping enhances driving comfort and protects the vehicle body. Automotive weatherstripping typically has an adhesive backing for easy attachment to automotive parts. Currently, most domestic OEMs use pressure-sensitive adhesive tape as the adhesive backing for automotive weatherstripping. The pressure-sensitive adhesive tape is hot-air bonded to the weatherstripping, and then output to the bonding rollers by an adhesive backing traction structure. Existing adhesive backing traction structures include a frame and its attached tape roll, release paper winding roller, conveyor rollers, first tension wheel set, and multiple tape traction rollers, as described in the following patent:

[0003] For example, patent application number CN201621476147.9 discloses an automatic thermal adhesive bonding machine for automotive rubber sealing strips, including a frame. A rubber strip positioning and conveying device is mounted on the frame. The rubber strip positioning and conveying device has a tracked circulating conveyor chain, on which a rubber strip guiding and positioning clamp is mounted. Above the rubber strip positioning and conveying device is an automatic thermal adhesive tape bonding pressure roller, which has a thermal adhesive tape bonding guiding and pressing groove. The automatic thermal adhesive tape bonding pressure roller has a cooling chamber connected to a cooling water circulation device. The automatic bonding roller for thermal tape is mounted on a bonding adjustment mechanism that can adjust the bonding position. The input side of the automatic bonding roller for thermal tape is connected to a thermal tape leveling and feeding mechanism.
