ABSTRACT:
A system is provided for trimming excess vinyl film from a hoop assembly. The hoop assembly may be used to manufacture semiconductor workpieces. The system uses a pressure applying member applied to the excess film with a bearing surface sufficient to receive such pressure on the opposite side of the excess film. The system may be rotated such that the film is trimmed around the entire hoop assembly at the position of the pressure applying member. The bearing surface may be part of the support for the system or incorporated into the hoops.
