Abstract
A feed-in mechanism for feeding strip material in helical fashion into an accumulator while preventing any bending or bowing of the incoming strip material by maintaining the strip material in the helix under tension. The feed-in mechanism includes a plurality of circumferentially spaced, helically arranged strip guides which define a helical path for the incoming strip, and a traction feed and tensioning device respectively located at the entry and exit ends of the helical path. The traction feed pushes the strip material along the helical path while the tensioning device exerts a pulling force on the strip material to maintain the strip material in the helix under tension. The traction feed includes a stationary idler roller and a powered traction roller journaled in a pivoting frame. The pivoting frame is urged towards and away from the stationary idler roller under controlled squeeze pressure to obtain positive traction between the strip material and traction roller, while the overspeed or overdrive of the traction roller is controlled so as not to overtension and consequently permanently deform the strip material being pulled thereby.
