Edge rolling mechanism
Abstract
Abstract A TWO-STAGE STRIP MATERIAL EDGE ROLLING APPARATUS COMPRISES TWO PAIRS OF GROOVED ROLLERS MOUNTED ON UPPER AND LOWER FRAME MEMBERS THAT ARE PIVOTALLY CONNECTED TO A RIGID FRAME SYSTEM OF SIDE FRAME MEMBERS, SPACER MEANS AND A MOUNTING ROD. A SPRING BIASED MOUNTING MEANS ALLOWS THE APPARATUS TO BE COUNTERBALANCED IN "FREE-FLOATING" POSITION TO ACCEPT CHANGES IN THE ANGLE OF FEED OF MATERIAL. A WIDE RANGE OF MATERIAL WIDTHS MAY BE ACCEPTED BY THE FLEXIBLE WIDTH ADJUSTMENTS AND LATERAL CURVATURES OR DEVIATIONS OF THE MATERIAL ARE READILY ACCOMMODATED BY THE PIVOTALLY MOUNTED ROLLERS. GROOVE CONFIGURATION ON THE FIRST PAIR OF ROLLERS IS V-SHAPED WHILE THE LAST PAIR OF ROLLERS HAS A U-SHAPED CONFIGURATION SO THE FINAL MATERIAL EDGE IS SMOOTHED.
