    Abstract: A linoleum roll heater assembly for heating a roll of linoleum while in storage or at a job site located at a cold weather environment. The heater assembly includes a heater tube to be received through the roll of linoleum to be heated. The heater tube is supported for rotation between a pair of side support blocks to facilitate unrolling and dispensing the heated linoleum. An insulating and heating cover or blanket is removably wrapped around the linoleum roll to prevent the escape of heat. The linoleum roll is uniformly heated by respective heating elements of the heater tube and the heating blanket, whereby linoleum may be continuously disposed from its roll with the expenditure of a minimal pulling force.

    Abstract: A method for applying a blown polyurethane coating to carpeting or other sheet material. The method includes the step of adding a filler to the polyurethane components to assure that the liquid does not unduly penetrate porous goods. The mixed polyurethane components are then placed in a puddle on the sheet material and leveled to a uniform coating. Steam is passed through the sheet material and the coating to initiate the reaction of the components. The steam also adds water to the coating, so the formulation is such that additional water is needed, and the needed water is added by the steaming. After the polyurethane has completed blowing, and before the polyurethane has cured beyond its plastic state, the foam may be compressed to decrease the thickness. A second sheet of material can be placed over the polyurethane to prevent the polyurethane from adhering to the compressing roller.
