Abstract
The single-cylinder circular machine comprises a substantially vertical needle cylinder which is rotatable about an axis and supports a plurality of needles which are arranged in axial grooves of the outer skirt of the needle cylinder and can move individually along directions which are parallel to the needle cylinder axis. A platen is arranged coaxially above the needle cylinder and is supported, so as to be rotatable about the needle cylinder axis, by the supporting structure of the machine. The machine comprises first connecting members which can be controllably activated or deactivated in order to rigidly associate the platen, in its rotation about the axis, with the needle cylinder, and second connecting members arranged on a wing of the platen which extends inside the needle cylinder and on a portion of the inner surface of the needle cylinder which faces the wing. The second connecting members interact magnetically with one another, thereby transmitting rotary motion of the needle cylinder to the platen.
