Abstract: A warp beam particularly adapted for warping, section warping or winding of threads, yarns, textile material or synthetic melt-spun polymeric plastic material which is defined by a metallic tube having axially opposite ends in which is inserted and fixed thereto an annular reinforcing/compensating member at each tube end, a flange member having a collar at each end with the collar being inserted in the annular reinforcing/compensating member, and each annular reinforcing/compensating member having a machined surface effectively compensating for out-of-roundness of the tube which results from manufacturing tolerances thus assuring when the elements of the warp beam are welded to each other a strong, unstressed, uniform, concentric and balanced structure.

Abstract: The thread reeling apparatus includes a rotary cam drum with a traversing thread guide assembly used to guide a thread from a delivery mechanism to a bobbin or thread package. A roller having a smooth, peripheral surface is interposed at a location downstream of the rotary cam drum along which the traversing thread guide assembly moves back and forth. A further traversing thread guide assembly located downstream of the smooth roller receives the thread from the smooth roller and transfers the same on to a bobbin or thread package driven by a friction roller. The disposition of the smooth roller and further traversing thread guide assembly controls the tension of the thread along the thread path.

Abstract: The assembly for winding yarn on a thread package comprises electrically operated friction drive means and electrically operated axial drive means. The mandrel tube which carries the bobbin tube and the thread package is frictionally driven. The mandrel itself is axially driven by the electrically operated axial drive means. The friction drive and the axial drive are effective to operate in tandem. The friction drive comprises a synchronous motor. The axial drive includes a three-phase a.c. motor, a reluctance motor, or a d.c. motor.
