Abstract
Abstract A thread feeder for textile machines having a winding body or storage spool between a thread supply and a textile machine. Means are provided for winding a plurality of coils of thread onto the winding body to form a store of coils of thread, such means comprising generally a rotating winding eye or frame. The winding in all cases proceeds by virtue of an axial shifting of the coils of said store axially along the winding body from the location where they are laid down to the point where they are removed. The winding body is stationary and various means are provided to effect the axial shifting. The thread passes through the axial center of the winding body, either during the process of laying the coils down in the store or in the process of removing the coils from the store. The speed or activity of the means which wind the coils is controlled by the number of coils in the store which is disposed on the winding body at any time, simple switch means operated by the presence or absence of a certain number of such coils being the medium through which such control is effected.
