摘要

Paint roller tube is made from a thermofusible plastic material that melts at a lower temperature than the components of the pile fabric applied to its outer surface, while the inner surface of the fabric has projecting fibres or loops that engage with the melted surface of the tube when heated. The paint roller tube (5) is made from a thermofusible plastic material that melts at a lower temperature than the components of the pile fabric (1) applied to its outer surface, while the inner surface (2a) of the fabric has projecting fibres or loops (4) that engage with the melted surface of the tube when heated. The pile fabric is applied with pressure to the tube after its inner surface has been scratched or roughened to produce projecting loops or fibres, with the tube heated and subjected to a simultaneous lengthwise and rotary motion to melt or soften its surface.
