Tape tension control system
摘要:
A method and system for tensioning and applying a foam core tape having pressure sensitive adhesive faces to a body side molding. The method is effected to obtain the necessary stretch in the foam core tape to coordinate with any dimensional changes which may occur in the body side moldings to which it is bonded. The system includes a tensioning roll disposed between a supply roll and the point of application of the tape to the body side molding. The peripheral surface of the tensioning roll frictionally engages the foam tape and the rotation of the tensioning roll is controlled by suitable braking mechanism to effect a desired stretch in the tape prior to its application to the body molding.
