A system and method for producing a spool having a continuous fabric strip is disclosed which produces an extended length fabric strip made from a plurality of seamed standard lengths of the fabric, the extended length fabric strip being substantially spirally wound upon a hollow core with consecutive windings of the extended length fabric strip being located close adjacent each other, and with consecutive rows of the extended length fabric strip overlaying each other on the hollow core. In a first embodiment, the standard length fabric strips are joined together at their respective contiguous ends using a small strip of heat-activated seaming tape. In a second embodiment, the standard length fabric strips are stitched together at their respective contiguous ends using thread. The winding operation simultaneously controls both the lateral position at which the extended length fabric strip is wound onto the core and the rotation of the core to achieve the tight and highly compact winding operation, with the speed of the winding operation being controlled according to the amount of the extended length fabric strip which is available at any given time. The extended length fabric strip is suitable for use in the manufacture of paint roller covers.
