Claim Text:
1. A double-cylinder circular machine for producing tubular knitted manufactures comprising: a supporting structure, which is provided with a footing for resting on the ground which supports, so that said supporting structure rotates about said supporting structure's own vertically-oriented axis; said supporting structure further comprising at least one column which is extended substantially vertically, protrudes upward from said footing, and supports, so that said supporting structure rotates about said supporting structure's own axis; a lower needle cylinder; an upper needle cylinder, which is arranged above said lower needle cylinder; a main motor actuating said lower cylinder and said upper needle cylinder with a rotary motion about their axes; said main motor being connected kinematically to said lower needle cylinder and to said upper needle cylinder by a main shaft, which is arranged within said column and is oriented so that the main shaft's axis is vertical; wherein said upper needle cylinder is supported so that said upper needle cylinder rotates about its own axis by an arm, which in turn is supported by said column so that said upper needle cylinder rotates about the axis of said main shaft; said arm rotating about the axis of said main shaft with respect to said column for the transition of said upper needle cylinder from an active position, in which said upper needle cylinder is arranged coaxially to said lower needle cylinder, to an inactive position, in which said upper needle cylinder is spaced with its axis laterally to the axis of said lower needle cylinder, and vice versa, said rotation means being affected by said motor.
