Abstract: A method and apparatus for making a paint roller having a natural skin cover are provided. The natural skin cover being bonded to the paint roller using a thermoplastic material, preferably polypropylene, and the natural skin cover being formed from a strip of natural skin, such as lambskin, provided in a width sufficient to accommodate shrinkage in the manufacturing process. The resulting product providing a superior natural skin covered paint roller that is substantially integral and that will remain integral when exposed to paint solvents.

Abstract: An apparatus and method for the production of a thermoplastic tubular structure is disclosed. The apparatus comprises a stationary mandrel, a first and second feeder for feeding a first and a second strip to a mandrel at a first location and second location respectively, and a third feeder for feeding a cover strip to the mandrel at a third location, the third location being downstream of the second location. A transport system adapted to wind and advance the strips as they are being fed to the mandrel is used to helically wind the fed strips around the mandrel. A head for dispensing a width of a liquefied thermoplastic material is also disclosed. The head is oriented to dispense the width of the liquefied thermoplastic material on at least part of a winding of the first strip and part of a winding of the second strip. A cutter is used for cutting the thermoplastic tubular structure into predetermined sizes.

Abstract: A method and apparatus for making reusable paint rollers comprised of a core formed of thermoplastic material. The core is formed by helically winding one or more strips of thermoplastic material about a stationary mandril. A layer of adhesive is then applied to the outer surface of the core whereupon a cover, applied as a strip of material or as blown on fibers, is bonded thereto. The core may also be formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril. The paint roller may also be made by bonding, in a single step, the fabric cover to the wound strip wrapped about the mandril. The cover is then pressed onto the core to form a tight and secure bond therebetween.

Abstract: The present invention relates to a paint roller having an open end which can be inserted into an applicator handle and a surface area adapted for use in painting. The core of the roller is made from a core material and the core has an inner surface and an outer surface. A major portion of the core has a substantially uniform thickness. A cover is affixed to substantially all of an outer surface of the core and a processed region at one end of the core has a reduced thickness which is less than the substantially uniform thickness of the major portion of the core. The processed region of the core is folded inward such that the one of the core and the reduced portion of the core material are not exposed at the end of the paint roller.

Abstract: The present disclosure provides a method for the identification of nucleotide sequences which encode selenoproteins. Nucleotide sequences are translated in all potential reading frames, those with a relatively large number of UGA or TGA codons are noted, and frameshift-dependent open reading frames and SECIS elements are identified as associated with selenoprotein coding sequences, especially those within or overlapping known open reading frames. Further provided are selenoprotein coding sequences which are associated with certain viruses (e.g., HIV and Ebola), cancer-related genes and coding sequences related to normal functioning of the immune system.

Abstract: A reusable multi-strip laminate paint roller and method for manufacturing the same. The method comprising steps of: advancing a first strip of polypropylene material about a mandrel; advancing a second strip of polypropylene about a mandrel in offset relation to the first strip; advancing a cover about the second strip of polypropylene; providing a first adhesive layer (preferably a liquefied polypropylene) between the first and second strips of polypropylene; providing a second adhesive layer between the second strip of polypropylene and the cover; and applying a compressing force upon the cover urging the cover toward the second strip and simultaneously urging the second strip toward the first strip, thereby creating the continuous laminated paint roller. After forming of the continuously paint roller it is moved towards a cutter by a helical drive belt system.

Abstract: A method and apparatus for making reusable paint rollers comprised of a core formed from a strip of thermoplastic material. The thermoplastic material is formed into a core by helically winding about a stationary mandril. A layer of adhesive is then applied to the outer surface of the core whereupon a cover is bonded thereto. In a first embodiment the core is formed by winding a plurality of thermoplastic strips about the mandril. In a second embodiment the core is formed by applying liquefied thermoplastic material to a driven belt which transfers the thermoplastic material to the mandril. In yet another embodiment, the paint roller is made by bonding, in a single step, a fabric cover strip to a wound strip wrapped about the mandril.
