Abstract:
A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/−0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.
