ABSTRACT:
An apparatus is described for separating a plurality of immediately adjacent strands of metallic sheet severed from a continuous moving flexible metallic sheet, e.g. aluminum sheet. The apparatus includes a rotatable roll over which the adjacent strands pass, this roll having a resilient outer periphery. A plurality of radial slots are formed in the resilient periphery, forming annular resilient rings therebetween. These slots are laterally spaced and are inclined inwardly toward the axis of the roll and toward the transverse central plane of the roll. The slots are of progressively increasing depths from the transverse central plane of the roll to the outer ends thereof. The annular resilient rings so formed are adapted to provide separations between adjacent strands when the strands are maintained at a constant wrap angle on the separating roll.
