ABSTRACT OF THE DISCLOSURE The present invention provides an apparatus for manu- facturing a paint roller comprising an elongate support for a thermoplastic tubular core; means for winding a fabric strip over the tubular core in a helical path, said winding means including means for guiding the fabric strip to the tubular core at an angle to the axis of the core; and means for heat softening the surface of the core in the zone of the winding of the fabric strip around the core to fuse the fabric to the core; and means for causing relative movement between the winding means and the core in timed relation to the rotation of the elongate support, whereby the fabric strip is wound around the core in a tight helix, with consecutive windings of said strip being adjacent to one another to form an integral cover over said core. The pre- sent invention also provides a method for manufacture of a paint roller, comprising heat-softening the surface of a tubular core composed of thermoplastic material and applying a fabric cover to the heat-softened core while rotating said tubular core so as to cause said fabric to be fused to the core without an intermediate adhesive.
