METHODS FOR MANUFACTURING A PAINT ROLLER WITH GROOVED SUBSTRATE |
摘要 |
A method for improving strength of the finished product in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method utilizes a substrate such as a polypropylene strip with grooves on its surface. The grooved substrate is fed onto a mandrel to form a tube. Adhesive is applied upon the grooved surface of the grooved substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The hardened adhesive in the grooves may operate to reduce the hoop-force which would otherwise tend to unwind the wound substrate. The method in certain embodiments provides a reduction in cost and weight of the finished product.
