Flower Pattern And Roll Positioning Design For The Cage
Feb 01 2019 The above researches on roll pass or flower design are mainly for conventional roll forming processes. In conventional roll-forming processes a metal strip is gradually bent into desired shape by using contoured vertical and horizontal rolls mounted on roll stands as shown in Fig. 1 Gmbh Schuler 1996.The formed strip at each stand is shaped definitely by the contours of rolls i.e. there .
