摘要	PURPOSE: To prevent a collapse of an overall shape of a formed net by providing notches of the same number in a structure that coincides with the notches of a fixed die at a mold attaching unit for forming the net. CONSTITUTION: A plurality of peripheral notches 4 each having a substantially rectangular section for forming the net are formed at fixed die elements 1. A layer G of the net, at the time of being formed between the elements 1, is passed over a die attaching unit 5. A plurality of notches 7 coincident in number, shape and dispositions to those of the notches 4 of the elements 1 are formed on a surface 6 of the unit 5 for passing the layer G. The notches 7 have a function of supporting and guiding the state coincident in the shape to longitudinal strands of the net to prevent deformation and collapse of the net. The net having a large width and thickness can be formed. COPYRIGHT: (C)1990,JPO
