Abstract
A paint roller manufacturing system includes a cover dispenser for continuously dispensing a windable width of paint roller cover fabric, a fabric supporting and advancing device for supporting the fabric and maintaining a width-wise dimension of the paint roller cover fabric as the fabric advances, a fabric coating applicator for applying a coating to the back side of the paint roller cover fabric while the fabric supporting and advancing device maintains the fabric in a width-wise dimension, and a compressing roller positioned downstream of the fabric coating applicator and configured to apply a compressive force on the coating after it has been applied to the back side of the paint roller cover fabric and while the fabric is supported by the fabric supporting and advancing device. In two-strip embodiments, first and second strip dispensers continuously dispense a first and second windable width of strip material. A guide system guides the first and second strip coming from the first and second strip dispensers to be wound about a mandrel and guides the coated paint roller cover fabric from the fabric supporting device to be wound about the first and second strips. An adhesive ap…
