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.

A canister-yarn tensioning assembly is adapted for controlling tension in a running yarn drawn from a yarn supply package located within an open-top canister. The canister-yarn tensioning assembly includes a cylindrical adapter configured to reside at a mouth of the open-top canister. The adapter defines an unobstructed package transfer space sufficient to allow the yarn supply package to be manually lowered through the adapter and into the canister. A pivoted support arm is carried by the adapter, and configured to pivot at a connection point located on a peripheral flange of the adapter. One or more yarn tensioners are carried by the pivoted support arm, and are movable between an operative position within the package transfer space and an inoperative package-replacement position outside of the package transfer space.

A device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

A yarn tensioner is adapted for adjusting tension in a running yarn. The yarn tensioner has a base, an adjustable pin rack, a fixed pin rack, and a fastener assembly. The adjustable pin rack is carried by the base and incorporates a first plurality of spaced apart parallel friction pins. The fixed pin rack is carried by the base and incorporates a second plurality of spaced apart parallel friction pins residing alternately between the friction pins of the adjustable pin rack. The running yarn travels across the yarn tensioner by snaking over and under adjacent parallel friction pins of the adjustable pin rack and the fixed pin rack. The fastener assembly attaches the adjustable pin rack to the base, such that the adjustable pin rack is movable relative to the fixed pin rack, thereby controlling frictional drag on the running yarn.
