ABSTRACT:
There is disclosed apparatus for reforming a work material into a flat configuration. A pair of first and second sprockets are mounted respectively on a drive shaft and a driven shaft disposed parallel relation to each other, the pair of sprockets being rotatable at the same speed. A first endless belt includes a plurality of first reforming rolls rotatably supported at their opposite ends by opposed first endless chains. A second endless belt includes a plurality of second reforming rolls rotatably supported at their opposite ends by opposed second endless chains. The first and second sprockets are engaged respectively with the first and second reforming rolls to move the first and second endless belts, respectively, and the first and second reforming rolls are brought into frictional rolling engagement respectively with opposed first and second support plates provided respectively in the first and second endless belts. The work material introduced into a housing through an inlet is passed between the opposed first and second reforming rolls, thereby reforming the work material into a flat configuration. With this construction, the reforming apparatus achieves a high flatness precision, and can be of a compact size, and is not expensive.
