The invention relates to a drum intermediate storage of yarn for a textile machine having a driven rotary drum with a working surface and a movable radial rotary arm. The driven rotary drum is coupled with a first drive and the arm is coupled with a second drive, whereby both drives are composed of motors and both motors are connected to a control system of the textile machine. The radial rotary arm is provided with a yarn guide, whose working portion upholds the yarn radially relative to the axis of rotation of the drum.

A yarn winding assembly installed on a support includes a motorized spool and an oblique spacer pin, between which a yarn is wound. The spacer pin is supported rotatably by a rotating supporting component so that it is entrained in two directions by the yarn wound between the spool and the spacer pin. The rotation of the spacer pin is delimited by an element of arrest at least in a direction of unwinding the yarn.

A compact device for controlling the supply of a textile or metal thread to a processing machine, such as a textile machine or a spooling or winding machine, includes a body, at least one rotary member with which the thread cooperates, the member associated with a rotation velocity detector for detecting the rotation velocity thereof, the detector connected to a control unit, a tension detector provided for detecting the thread tension connected to such control unit. The rotary member is idle and is placed in rotation by the thread which is moved thereon, in proximity to such member the tension detector being placed. Also disclosed is a method for controlling the supply of thread actuated by such device.
