摘要

PROBLEM TO BE SOLVED: To make variable the length of the molded face width of a straight- line section of an inner frame and make one inner frame deal with various kinds of PC products. ;SOLUTION: An inner frame 12 of a PC product forming frame 10 is divided into corner sections and a straight-line section so that the frame is constituted of corner section frames 16 and the straight-line frames 18. Overlapping sections of the corner sections frames 16 and the straight-line section frames 18 are formed into the thin plate shape, and thin plate sections thus formed are brought into contact with slidably one another and overlapped. Varying mechanisms 19 such as turn buckles 20 or the like for varying the overlapping amount which are holdable on the varying positions are provided, and the varying mechanisms 19 are adjusted so as to vary the length of respective sides of the inner frame 12.;COPYRIGHT: (C)2000,JPO
