摘要： 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.

摘要： A system and method are provided for conditioning paint roller cover fabric inline in a continuous paint roller manufacturing process. The system and method provide an inline fabric conditioning unit upstream of the point in the process that the paint roller fabric cover strip is wrapped about the outer side of the outer strip, the fabric conditioning unit including a fabric conditioning device that conditions the paint roller fabric cover strip as it is being fed towards the outer side of the outer strip. The fabric conditioning unit may be used to perforate the fabric, to remove loose fibers from the fabric side of the paint roller fabric cover, to buff the paint roller fabric, and to orient the paint roller cover fibers. The continuous paint roller manufacturing process includes steps of feeding an inner strip and an outer strip towards a mandrel, wrapping the inner strip and the outer strip about the mandrel in offset relation, applying a strip adhesive to at least a portion of an outer side of the inner strip and at least a portion of an outer side of the outer strip, feeding a paint roller fabric cover strip having a fabric side and a backing side towards the outer side of the outer strip, the fabric side comprising loose fibers and attached fibers, forming a paint roller tube by wrapping the paint roller fabric cover strip about the outer strip at a point in the process after the strip adhesive has been applied to the outer side of the outer strip such that the backing side contacts the strip adhesive, applying compression to the paint roller tube, and cutting the paint roller tubes into like lengths.
