ABSTRACT:
The machine according to the invention is intended for making cone shells by coiling up sheet blanks in the form of a circular sector. The machine comprises adjustable clamps for clamping the radial edges of the blank, said adjustable clamps being located on the base with a provision for turning towards each other with relation to their fixing point and for turning around their own longitudinal geometrical axis for which purpose the ends of the adjustable clamps are provided with hinges. Each adjustable clamp has also a device intended to prevent its turning around its own longitudinal geometrical axis. As a result, the machine can be used successfully for making cone shells with practically any coning angle.
