摘要： A web (10) of material has a plurality of stems (12) extending from at least one side of the web. The web includes a first layer (14) of material having a first side and a second side and a second layer (16) of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the plurality of stems extend. The first and second layers of material are joined together while they are both molten, before either layer has cooled. The first and second layers of material can be formed of thermoplastic material or melt processable polymeric material. A method of making a web of material includes selecting a first material for a first layer of material and selecting a second material for a second layer of material. The first and second layers of material are melt formed. Then, the first and second layers of material are joined while the layers are in the molten state to form a multiple layer sheet. Next, a plurality of stems are formed on at least the second layer of material. Melt forming can include simultaneously melt forming the first and second layers of material such as by coextrusion.

摘要： A textile pull roll cover (20) is disclosed which has a plurality of surface stems (28) projecting outwardly from one side thereof. The surface stems are uniformly shaped and disposed on the pull roll cover, and the surface stems collectively define an operative contact surface for a textile web. A plurality of hooking stems (55) project from an opposite side of the pull roll cover. The hooking stems are adapted to releasably affix the pull roll cover to a cylindrical pull roll having loop structure material (45) adhered thereto. A method for making a textile pull roll is disclosed, as well as a method for changing the outer textile engaging surface of a textile pull roll using the hook-and-loop opposed fastening arrangement, with the loop material being disposed on the outer cylindrical surface of the pull roll. Also disclosed is a textile pull roll cover which has an exterior side (251) with desired frictional characteristics for engagement with an advancing textile web. On its opposite side, the pull roll cover is affixed to a cylindrical outer surface of a textile pull roll by a repositionable pressure sensitive adhesive disposed therebetween. A method for making a textile pull roll is disclosed, as well as a method for changing a pull roll cover using repositionable pressure sensitive adhesive.

摘要： A longitudinally extending web of lofty nonwoven abrasive surface treatment material is provided in a coreless roll form to the end user. Successive wraps of the nonwoven abrasive material have interengaging surfaces sufficient to maintain the material in a spirally wrapped configuration yet being readily separable. A plurality of longitudinally spaced and laterally disposed perforations through the web permit the user to successively separate the web into a plurality of sheets of abrasive surface treatment material. In a preferred embodiment, the roll is encased in a protective shrink wrap sheath, and each sheet is separated from the roll by separating said sheet from an innermost wrap of the roll. In another preferred embodiment, the abrasive surface treatment material includes abrasive particles of 1000 grade of finer.

摘要： The present invention embodies covers, especially those used in the textile industry. Some covers are made of a polypropylene comprising less than 90 percent isotactic linkages and a thermoplastic block copolymer comprising hard segments of polystyrene combined with soft segments. Other covers are made of metallocene-catalyzed polyolefins and thermoplastic block copolymers. The durable-abrasion resistant covers typically have a high static coefficient of friction.

摘要： A method is provided that includes a starting material of a first sheet (152) having first and second major sides, with the first side of the first sheet being adapted for adherence to a substrate sheet, and providing a second porous sheet (154) having first and second major sides. The first side of the second porous sheet is aligned against the second side of the first sheet. A molten thermoplastic material (156) is introduced onto the second side of the second porous sheet. The method includes the step of simultaneously urging the molten thermoplastic material against the second porous sheet to force portions of the thermoplastic material to flow through the second porous sheet and into adhering contact with the second side of the first sheet, and molding a desired surface pattern on an exposed surface (158) of the molten thermoplastic material. The molten thermoplastic material is cooled to bind the material to the first (152) and second (154) sheets and define a laminated assembly.

摘要： Compositions have been created comprising a blend of a polypropylene having less than 90 percent isotactic linkages and thermoplastic block copolymers. Specifically, the thermoplastic block copolymers comprise hard segments of polystyrene combined with soft segments comprising 2 to 8 carbon atoms. Some of the physical characteristics of materials made by these compositions are more desirable than the same physical characteristics of materials made of the polypropylene having less than 90 percent isotactic linkages used to make the composition and of the same physical characteristics of materials made of the thermoplastic block copolymer used to make the composition.
