Abstract
Abstract A method relates to a method of making a laminated i body having a bended part which consists of an upper layer I member (10) and a synthetic resin 13 and being in good accordance with the each center point of the upper layer member 10 and the synthetic resinous body which comprises the steps of: arranging the upper layer member 10 between an upper layer member-fixing frame 4 and the female mold 3; holding the periphery 12 of the member 10 ; giving form to the member 10 and at the same time cutting the member 10 between the outer side face 8 edge 8a of the male mold 2 and the inner side face 9 edge 9a of the female mold 3 within measure by mold-tightening the female and male molds together; supplying a required molten resin 11 prior to the completion of the above-mentioned cutting ; and molding the laminated body 14 aimed-at. And an apparatus 1 which comprises at the very least a male mold 2, a female mold 3, an upper layer member-fixing frame 4, an expanding and contracting means 5, and both the outer side edge 8a of the male mold 2 and the inner side edge 9a of the female mold 3 consist of the cutter of the upper layer member 10.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
271 words
A method of making a laminated body with a bended part consisting of an upper layer member, and a synthetic resin, which comprises at least holding an upper layer member between an upper layer Member-fixing frame and the female mold, giving form to the upper layer member supplying a required molten resin and molding the molten resin which is characterized in that ; arranging the upper layer member between an upper layer member-fixing frame which is attached shiftably either on the side of a male mold or on the side of a female mold of a molding apparatus provided with the male mold and the female mold both sliding on the each face of the whole circumference and which has a sliding opening where the outer side face of the male mold slides over the whole circumference and the convex parts of the male mold inserts through, and the female mold ; holding the periphery of the upper layer member between the upper layer member-fixing frame and the female mold; giving form to the upper layer member and at the same time cutting the upper layer member off between the outer side face edge of the male mold and the inner side face edge of the female mold within measure by mold-tightening the female and male molds together; continuing to place the upper layer member thus given form while leaning as it stands; supplying a required molten resin from a molten resin passage between the upper layer member and the male mold prior to the completion of the above-mentioned cutting; and molding the molten resin to obtain the laminated body aimed-at.
Claim 2
Independent Claim
271 words
A method of making a laminated body with a bended part consisting of an upper layer member, and a synthetic resin, which comprises at least holding an upper layer member between an upper layer Member-fixing frame and the female mold, giving form to the upper layer member supplying a required molten resin and molding the molten resin which is characterized in that ; arranging the upper layer member between an upper layer member-fixing frame which is attached shiftably either on the side of a male mold or on the side of a female mold of a molding apparatus provided with the male mold and the female mold both sliding on the each face of the whole circumference and which has a sliding opening where the outer side face of the male mold slides over the whole circumference and the convex parts of the male mold inserts through, and the female mold ; holding the periphery of the upper layer member between the upper layer member-fixing frame and the female mold; giving form to the upper layer member and at the same time cutting the upper layer member off between the outer side face edge of the male mold and the inner side face edge of the female mold within measure by mold-tightening the female and male molds together; continuing to place the upper layer member thus given form while leaning as it stands; supplying a required molten resin from a molten resin passage between the upper layer member and the male mold prior to the completion of the above-mentioned cutting; and molding the molten resin to obtain the laminated body aimed-at.
Claim 3
Dependent Claim
