Abstract:
Described are methods of making a paint roller using an adhesive made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using preformed strips or core material made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using a composite cover material made from a compound of polypropylene and calcium carbonate having between 5% and 50% calcium carbonate by weight. One or various compounds may be used to form portions of one or multiple components that make up the paint roller, including, for example, the thermoplastic strips, adhesives and/or the backing of a composite cover material. The materials can be assembled in a continuous manufacturing process.
Abstract:
A method of manufacturing paint roller covers is disclosed in which the paint roller covers are manufactured from a seamless, tubular fabric sleeve knitted in a pile side-in manner and including at least one of a backing material and a pile made, at least in part, from a low melt fiber or yarn component. The seamless, tubular fabric sleeve is inverted to a pile side-out configuration, placed onto a cylindrical member, and heat is applied to cause the low melt fiber or yarn in the backing and/or looped ends of the pile to be activated and to closely conform to the size of the cylindrical member, thereby causing the melted and fused together, re-hardened low melt component of the seamless, tubular fabric sleeve to remain in a cylindrical configuration, forming an integrally formed core member.

The activated tubular knitted pile fabric may be finished into paint roller covers by combing and shearing the pile fabric to a desired length, beveling the edges of the paint roller covers, and vacuuming stray fibers from the paint roller covers.
Abstract:
A method of manufacturing paint rollers includes the steps of extruding a cylindrical plastic core through a rotating extruder head, and securing an absorbent sheet material onto an outer surface of the core in a continuous process.
Abstract:
An applicator includes a cylindrical core having an interior surface and an exterior surface. A backing layer is attached to at least a portion of the exterior surface of the cylindrical core. A fabric material is attached to at least a portion of the backing layer. The fabric material is formed of polytetrafluoroethylene (PTFE).

Abstract:
Se refiere a un procedimiento para obtener un molde (12) en cuyas paredes interiores se incluyen unos rehundidos (2) correspondientes a diferentes motivos decorativos, para poder fabricar rodillos (10) que están constituidos a partir de un rodillo esponjoso (4) que queda recubierto de una capa de poliuretano (9) en cuya superficie se incluyen los motivos decorativos en relieve (2a), para permitir realizar incisiones sobre una superficie enlucida y aún húmeda, con los motivos decorativos impresos. Tiene la gran ventaja de que se puede realizar cualquier motivo decorativo para grabarlo sobre una superficie enlucida mediante un rodillo (10) .
Abstract:
The invention relates to a method and a device for the manufacture of paint rollers by winding a textile fabric (3) onto a plastic tube (2) along a spiral-shaped line. According to the invention, a number of tube elements (6), having a length suitable for a paint roller, are slipped onto a revolving mandrel (1). The tube elements are clamped together so as to engage one another and so as to allow them to be rotated together with the mandrel (1). The mandrel is rotated at the same time as the fabric is wound on and attached to the tube elements, after which the fabric is cut at the joints (8) between the tube elements. Due to the invention, the cutting can be performed in the same machine without the risk of damaging the mandrel. As the cutting is made through the fabric only, this entails much less knife wear and is less energy-consuming. Preferably, the tube elements have a toothing at their axial ends for mechanical interconnection at the joints between the tube elements and with the mandrel (1).
Abstract:
A paint roller wrapping device comprises a rotatable holding means for a paint roller core tube (2) and a first heating block (1) arranged on said device to provide a first surface that is directly contactable with the surface of a rotating paint roller core tube (2), which in use, is held by said holding means and heats the surface of a paint roller core to a molten state that is suitable for adhering a wrapped fabric (20).
Abstract:
A method for reducing cost and weight in paint roller manufacturing processes and other continuous processes for producing tubular goods from polymers. The method may utilize a perforated substrate such as a perforated polypropylene strip or may include a perforating step which removes overage from an unperforated substrate. An unperforated substrate, which may be of a thinner gauge than the perforated substrate, is fed onto a mandrel. The perforated substrate is fed onto the unperforated substrate to form a tube. Adhesive is applied upon the outer surface of the perforated substrate. A cover may be applied about the tube, and the resulting product is then cut into finished-size paint rollers. The removal of the overage results in a reduction in the weight of the paint roller. In certain embodiments the overage from a perforation step is collected, and may be reused in a subsequent implementation of the method or resold.
