Manufacturing method null of metal make gossamer Hari framework body for silk photoengraving

摘要

PROBLEM TO BE SOLVED: To mitigate labor involved in the manufacturing of a framework with a gauze stretched across and stretch the gauze precisely and in an adequately tense state. ;SOLUTION: This metal framework is made up of a metal skeletal framework 1, of a closed chain ring shape, on the upper face of which synthetic resin powder 2a of a polyethylene counterpart is laminated at spots on the entire periphery. Further, these skeletal framework 1 and synthetic resin powder 2a are heated to form a synthetic resin layer 2 of an appropriate thickness bonded to the upper surface of the skeletal framework 1, then a gauze of polyester fiber is placed to cover the synthetic resin layer 2, and these materials are heated to embed the peripheral edge of the gauze into the synthetic resin layer 2. Finally the materials are cooled and fixed together.;COPYRIGHT: (C)1998,JPO
