Abstract (en)

This invention concerns a machine with three operating rolls, two of which are lower (12, 13) and placed side-by-side on axes with a fixed height, and an upper central one (14) on a movable axis that can be varied in height. The upper central roll (14) is commanded by a chain transmission (19), derived from the geared transmission that drives the lower rolls. The chain transmission is set more or less vertically and to one side of the axis of the upper central roll, which it engages tangentially. <IMAGE>

The bending machine comprises rolls set in motion by an electric motor (16') using series of gears (17) commanding lower roll via idler gear (18). The upper roll is commanded by a chain transmission (19). The chain passes over a first toothed wheel (20) and over second toothed wheel (21). A branch (19') of the chain is practically vertical, acting upon a third toothed wheel kept in permanent contact with latter via a plate (23).
