ABSTRACT:
Apparatus for wrapping web material about an elongated object, particularly one which is asymmetrical to a rotational axis thereof, includes a frame, a cylindrical support member mounted in the frame and an annular resilient sleeve loosely surrounding the support member longitudinally thereof. The object is mounted so that it creates a nip with the sleeve and the web material is fed into the nip. The object is rotated on its rotation axis to draw the web material through the nip and to wrap the material on the object. As the object rotates the sleeve will also rotate on the support member and it will deform radially to conform to the object as material is wrapped thereon. The deformation and almost instant changes in angular velocity of the sleeve reduces tension variations in the web material and result in a uniform covering of the object as it is wrapped.
