PURPOSE: To ensure connecting work by disposing a fastener between surfaces of synthetic resin films of two connecting belts processing a sheet of paper and the synthetic resin film by laminating, and constructing a grasping section at both sides of the connecting belts. CONSTITUTION: Surfaces of synthetic resin films 19 of connecting belts 16, 17 which stick the synthetic resin film 19 to a sheet of paper 18 to process by laminating are contacted inwardly. A screw 3 as a fastener, projecting its head 3b and screw section 3a, is put therebetween at regular intervals. A heat seal 20 is given to the both side sections of the connecting belts 16, 17 of the screw 3 to construct a cylindrical grasping section 21 where the screw 3 is grasped. Dotted lines 22 for easily cut the connecting belts 16, 17 are provided to facilitate use of an automatic driving machine. Thereby the fastener is firmly put therebetween, cut pieces are not remained on the screw sections 3a, and connecting work can be ensured.
