The present invention discloses a dual-band-material conveying device which comprises a material distributing device (4), a feeding device (5) and a conveying line (6). The material distributing device (4) comprises an adjusting plate (44), two limiting pillars (41) and a material distributing pillar (43). The adjusting plate (44) is mounted on the conveying line (6) through a mounting pillar (45), the adjusting plate (44) is provided with an adjusting groove (42) in which the two limiting pillars (41) and the material distributing pillar (43) are mounted. The conveying line (6) is provided with a pit, and the feeding device (5) is mounted in the pit. The feeding device (5) comprises a movable feeding device body (51), a fixed feeding device body (53) and two guide frames (54). The movable feeding device body (51) and the fixed feeding device body (53) are mounted between the two guide frames (54).

A breaker roll apparatus assembly for minimizing coil breaks in strips has a frame, a center roll extending from a rail mounted to the frame and actuated by a hydraulic cylinder, and a plurality of side rolls positioned on opposite sides of the center roll. The plurality of rolls extend from rails mounted to the frame and are also actuated by hydraulic cylinders. A coil mounting member uncoils a coil of strip through the assembly into contact with the center roll and at least one of the side rolls. Each of the rolls can be raised and lowered to accommodate various diameters and widths of coil.
