초록 ▼

This specification discloses strip sheet metal panels formed with transverse indentations and longitudinal formations formed therein, with end portions at each end of said panels being free of said transverse indentations; AND A METHOD OF COLD ROLLING STRIP SHEET METAL TO FORM BOTH TRANSVERSE AND LONGITUDINAL INDENTATIONS AND FORMATIONS THEREIN, AND DISCONTINUING FORMATION OF SAID TRANSVERSE INDENTATIONS AT PREDETERMINED SPACED INTERVALS ALONG SUCH SHEET METAL, AND SHEARING THE SHEET METAL IN MEASURED RELATION TO SUCH SPACED INTERVALS; AND FURTHER DICLOSES APPARATUS FOR EMBOSSING SHEET METAL, IN A SHEET METAL FORMING LINE ADAPTED TO FORM BOTH TRANSVERSE AND LONGITUDINAL INDENTATIONS IN SAID SHEET METAL, AND IN WHICH SAID FORMING LINE INCLUDES SHEET METAL DELIVERY MEANS, AND A PLURALITY OF SHEET METAL ROLLER STANDS FOR FORMING SAID LONGITUDINAL INDENTATIONS AND IN WHICH SAID EMBOSSING APPARATUS INCORPORATES TENSION ROLL MEANS LOCATED AND ADAPTED TO RECEIVE SAID SHEET METAL FROM SAID SHEET METAL DELIVERY MEANS, EMBOSSING ROLL MEANS LOCATED TO RECEIVE SAID STRIP FROM SAID TENSION ROLL MEANS AND MOVING DIE MEANS COOPERATING WITH SAID EMBOSSING ROLL MEANS THEREBY TO DRAW SAID SHEET METAL INTO FORMATIONS ON SAID EMBOSSING ROLL MEANS AND THEREBY FORM SAID TRANSVERSE INDENTATIONS IN AN INTERMEDIATE CENTRAL REGION THEREOF, AND, HOLDING ROLL MEANS ADAPTED TO ENGAGE SAID EMBOSSED INDENTATIONS AND HOLD SAID SHEET METAL IN SAID FORMATIONS, SAID SHEET METAL THEREAFTER PASSING THROUGH SAID ROLLER STANDS FOR FORMATION OF SAID LONGITUDINAL INDENTATIONS IN MARGINAL AREAS OF SAID STRIP UNAFFECTED BY SAID EMBOSSING ROLL MEANS AND MEANS FOR INTERMITTENTLY DISENGAGING SAID MOVING DIE MEANS FROM SAID EMBOSSING ROLL MEANS TO PERMIT PORTIONS OF SAID SHEET METAL TO PASS THEREAROUND WITHOUT FORMATION OF SAID INDENTATIONS.

대표청구항 ▼

The method of cold forming a continuously moving strip of sheet metal to form successive transverse indentations in a central portion thereof and longitudinal formations down the two side portions thereof said method comprising; forming a series of transverse indentations in a central portion of said strip by the closing action of continuously moving die means at a forming station while said strip sheet metal is moving along a predetermined path, and while simultaneously holding said strip in tension between two spaced points on opposite sides of said forming station whereby to prevent distortion of said strip during formation of said transverse indentations; subsequently roll forming continuous longitudinal formations in said side portions of said sheet metal strip which remain free of said transverse indentations, said longitudinal formations extending continuously along both said side portions of said strip, and, intermittently discontinuing said formation of said transverse indentations at predetermined spaced intervals along said sheet metal strip, whereby to leave lengths of said central portion between said continuous longitudinal formations which are flat and planar and free of said transverse indentations at spaced intervals therealong.
