Abstract
A device for feeding yarn with a constant adjustable tension, for use in weaving looms and in other weaving machines, comprises a brake acting on an end cap of the winding drum--held stationary--of the device. The brake is a plurality of elastically yielding metal elements, positioned radially in a support designed to envelope the cap and mounted with possibility of self-centering in respect of the cap, these elements engaging the outcoming yarn about a circumferential area of the cap having a slightly smaller diameter than that of the winding drum of the feeding device.
