1 more element
A method of making a paint roller comprising the steps of:
- applying an adhesive to a core tube having first and second opposite axial ends;
- and wrapping at least one tuftstring spirally around the core tube, thereby bonding the at least one tuftstring to the core tube, wherein the at least one tuftstring has a support strand and a plurality of discrete U-shaped bundles of yarn connected to the support strand.
A method of making a paint roller comprising the steps of:
- forming a tufted tape by attaching a plurality of tuftstrings to a backing tape, each of said tuftstrings having a support strand and a plurality of discrete U-shaped bundles of yarn connected to the support strand;
- applying an adhesive to a core tube having first and second opposite axial ends;
- and wrapping the tufted tape around the core tube, thereby bonding the backing tape to the core tube.
