Abstract
A method for making sectionally deformed band plate feeds by cold-rolling metal band plate feeds between work rolls wherein at least one of the work rolls has a barrel provided with a circumferential groove, a plurality of metal band plate feeds with substantially equal resistance to deformation, while overlaid one upon another, are rolled together between the work rolls to a reduction ratio of 30% or lower at one feeding operation, and the resulting metal band plate feeds are separated from each other.
Claims5
A method for making sectionally deformed band plate feeds by cold-rolling plane metal band plate feeds (1) between a set of work rolls (3), wherein at least one of said work rolls (3) has a barrel provided with a circumferential groove (3a), a plurality of metal band plate feeds (1) with substantially equal resistance to deformation, while overlaid one upon another, are rolled together between said work rolls (3) at a reduction of 30% or lower at one feeding operation and the resulting metal band plate feeds (1) are separated from each other.
