ABSTRACT:
Motorized expander comprising on a single driven shaft at least two cylinders rigid with the shaft at its ends, a central cylinder idly mounted between the cylinders and separated from them by free spaces, and at least one clutch member for transmitting rotary motion to the central cylinder situated in one of the free spaces. The central cylinder is provided on its surface with a pair of opposite handed spirals, and each of the two cylinders comprises a spiral opposite handed to that of the adjacent spiral of the central cylinder. The spirals are arranged together to define a stretching device for one or more fabrics of normal width when the central cylinder rotates rigidly with the shaft, or a stretching device for a fabric of double or multiple width when the central cylinder is provided with motion relative to the shaft.
