On or two strips of material are helically advanced about a mandrel, a layer of adhesive is placed on the strip(s), and a cover material having the trapezoidal cross section is helically wound about the adhesive. Prior to permitting the layer of adhesive to set, the cover material having the trapezoidal cross section is helically wrapped around the outer strip, and an inward compressive force is applied upon the cover material urging the cover material and the strip(s) toward the mandrel, forming the paint roller having a foam cover. The materials can be assembled in a continuous manufacturing process and the foam base has the shape of a trapezoid with one or more angles sufficient to eliminate gaps between the outer surface of successive helical winds on a finished paint roller. | 03-22-2012 |
20120277081 | ROLLING APPARATUS - A roller apparatus that may be used for efficiently dispensing the contents of a flexible tube may include a housing, a shaft and a cap. The shaft may be positioned in the housing and mounted to thereto by rotation in a first direction. The shaft may then be enclosed in the housing by placement a cap on the housing that also may function to engage an end of the shaft. Following insertion of the sealed end of a flexible tube though openings in the housing and the shaft, the tube may be taken up into the housing by further rotation of the cap, and thus the shaft, in the first direction. To remove the tube, the cap may be rotated in the opposite direction to release the shaft (and the tube now wrapped around the shaft) from the housing. | 11-01-2012 |
