Abstract: A magnetic strip material supporting looper system including one or more traversing looper cars with looper rolls thereon, operable in a moving magnetic material strip processing line to accumulate and store, and refeed, strip material for continuous strip movement and processing, while accommodating strip stoppage at entry and/or delivery stations and the like, the strip being accumulated in horizontal loops, each constituting upper and lower runs of strip material upon operational traversing of the looper cars, the lower run strands being supported from below the strip on a series of spaced rolls arranged to support the strip without interfering with travel of the looper cars, the upper run strands of material being magnetically supported from above and separated from the lower run strands thereof by a combined arrangement of horizontal, nonmagnetic, material contacting rotatable rolls and elongate magnetic means interposed therebetween, the upper run strands being supported and maintained in rolling contac
