Described is an industrial brush (1) comprising a brush body (2) obtained by the solidification of a metal in which the metal wires are locked in a rigid fashion for a first portion (3) thereby having a rigid body. The second portion of metal wires (4) is, on the other hand, free to perform brushing when the brush body (2) is rotated about a relative axis (5). The brush body (2) incorporates the metal wires with a structural coupling (with zero tolerance) which keeps unaltered the relative characteristics over time, with heat variations and at high speeds of rotation. It is also possible to construct the elements of traditional brushes with the same metal and a process is described for constructing new geometrical shapes for producing brushes with synthetic and natural wires with the traditional systems. Also described is a process for making a brush (1) comprising the steps of feeding in a mold (8) a metal in the molten state (melting temperature less than 2000 C.), in such a way that the first portion of the metal wires (3) is immersed in the metal which, when solidifying, forms a brush body with a rigid structure with a high mechanical strength such as to render perfectly stable the operation of the brush at high speeds and at high temperatures. During solidification of the molten metal there is also a heat treatment on the metal wires which improves their mechanical characteristics. Flanges, outer cups and inner cups with innovative embodiments can also be made with the same molding process, improving the characteristics of the traditional brushes.

The invention provides a brush bristle and a brush roll that exhibit a suitable abrasive force and that can reduce or eliminate the abrasion of a mill roll as much as possible. The brush bristle is for use in a brush roll B configured to scour a mill roll for rolling a metal sheet S, and includes one or more monofilaments 2 made of a thermoplastic resin containing abrasive particles. The abrasive particles have a hardness lower than the hardness of the mill roll, and higher than the hardness of the metal sheet S.

A twisted wire brush comprises a twisted wire core, and first and second lengths of spring coil. The twisted wire core comprises a first core wire intertwined with a second core wire. The first and second lengths of spring coil extend about the first core wire, and the second length of spring coil extends about the first length of spring coil. The first and second lengths of spring coil are pressed between the first core wire and the second core wire. In another embodiment, a method of making a twisted wire brush comprises providing a first and a second core wire, positioning a first length of spring coil to extend inside a second length of spring coil, and the first and second lengths of spring coil to extend about the first core wire, and twisting the first core wire and the second core wire about a core axis.

A power-brush apparatus has a housing and a brush rotatable on the housing about a brush axis and having bristles extending generally radially of the axis and having tips defining on rotation of the brush a circular orbit centered on the axis. The tips are engageable at a location with a workpiece surface. In accordance with the invention a blocking element is positioned radially inside the orbit immediately upstream from the location in a normal rotation direction of the brush. A drive rotates the brush in a working direction about the axis relative to the housing at a predetermined angular speed in the direction and thereby orbits the tips of the bristles about the axis such that the bristles engage the blocking element, are slowed thereby, and when released thereby snap back to accelerate forward and strike the workpiece at an augmented speed.

A shower brush system that includes an elongated body and an angularly adjustable showerhead with a combination cleaning surface and water dispersal system. The showerhead can be adjusted to clean the body or the bathing facility. Embodiments of the showerhead may include a removable insert that allows the user to choose from various brush heads or cleaning surfaces designed for different applications. These inserts can be removed, replaced, or disposed of when necessary. The shower brush systems of the present invention provide versatile and customizable cleaning solutions for users of and in a tub or shower.

The invention pertains to a novel scraper assembly having a plurality of interchangeable scraper heads and handles and corresponding method for use. The scraper assembly further comprises a plurality of abrasive mechanisms, namely spring bristles, coiled springs, chainmail abraders and wire cloth abraders capable of effectively cleaning a surface without scoring or otherwise damaging the surface. The invention may be particularly useful for cleaning grills and ovens. Additionally, the invention may also be useful for shaping, adding texture to, stripping materials from or otherwise preparing a surface, including wood, metal or ceramic surfaces.

The invention relates to a coated abrasive tool including a carrier which has a carrier material and including an abrasive surface coating on a surface region of the carrier. The abrasive surface coating has abrasive functional particles and a thermoplastic binder for an adhesive connection between at least some of the abrasive functional particles and the carrier material. At least some of the abrasive functional particles on the surface region of the carrier are partly integrated into the carrier material and are connected to the carrier material, and at least some of the abrasive functional particles on the surface region of the carrier are additionally partly integrated into the thermoplastic binder, the thermoplastic binder being connected to the abrasive functional particles and the carrier material.

A grill-cleaning tool includes a cleaning head and a cleaning implement connected to an underside of the cleaning head. The cleaning implement includes a first end and a second end opposite the first end relative to a length dimension of the cleaning head, and a first side and a second side opposite the first side relative to a width dimension of the cleaning head. The cleaning implement includes a compressible member and a scrubbing member covering the compressible member. The scrubbing member is fabricated from a metallic-mesh material and defines a working outer surface of the cleaning implement. At least one clamp is connected to one of the underside of the cleaning head and the cleaning implement. The at least one clamp is configured to secure the scrubbing member in place on the compressible member.

A tool for machining surfaces, edge regions, and contours comprising at least one disk-shaped base body rotatable around a tool axis and a plurality of flexible machining means, which are arranged on a circumference of the base body, wherein the machining means are formed rod-shaped and are arranged spaced apart from one another and extend substantially radially outward from the circumference of the base body, wherein at least two disks, between which the machining means are arranged, are arranged in the direction of the tool axis.

A brush assembly has a brush holder rotatable about a rotation axis, a ring brush carried on the holder and having an annular array of radially outwardly projecting bristles, and a stop element fixed adjacent the ring brush, of noncircular section. This stop element extends along and is rotatable about a longitudinal axis generally parallel to the rotation axis and projects into the array of bristles.
