Installed between shear & end welder and forming mill, horizontal spiral accumulator store a large amount of strip in a reasonable footprint space to give enough time for shear & end welder to cut and join the ends of two successive coils with non-stop tube mill. The principle of operation is simple. The strip is fed into the accumulator by a set of pinch rolls, before that, the strip is twisted 90 degree for entering the pinch rolls. As the strip enters the accumulator, it’s supported and conveyed by a rotary table or sets of rollers, which is sophisticatedly designed to minimize the resistance for reduced chance of strip cobbling, marking, tension etc. The inside wrap of the accumulated coil is pulled out thru center arbor to the forming mill. The drive has three modes: stopped, line synchronized, and high-speed feeding. The accumulator is designed for strip to outside feeding and center output. The number of strip wrap can be fixed or variable, depending on the thickness and width of material.
