A method and device for attaching and detaching material to a c-channel groove without requiring tools and without needing to access an end of the c-channel. The device comprises a coil-shaped element that is resiliently compressible and connected to a desired material. Through biasing or twisting the coil-shaped element, it is insertable at any point along a c-channel groove. The coil-shaped element is secured within the c-channel groove against separation therefrom through friction. A portion of the coil-shaped element can be extended outside of the c-channel groove for easy removal.

A building cleaning system for cleaning a side of a building can include an elongate brush structure that is rotated by an electric motor, a frame for supporting the brush structure that can be oriented to face toward the side of the building, and a plurality of air moving devices mounted to the frame for generating counterforce to force the frame toward the building. The air moving devices can including fans or blowers. The air moving devices can be being spaced apart from one another in an orientation that extends along the length of the frame. A lift arrangement can be provided for moving the frame along the side of the building.

Embodiments include a vehicle side washer assembly, a shaft assembly, and horizontal cloth brush panels. The side washer assembly includes a retractable angled primary arm, a retractable secondary arm, a shaft assembly having an upright shaft, and horizontal cloth brush panels. The upright shaft is disposed through a shaft attachment region of each of the horizontal cloth brush panels. The shaft assembly includes an upright shaft including notches and protrusions, and retrofit discs each including a shaft opening that matches contours of the upright shaft. Each of the retrofit discs includes rotary notches. The horizontal cloth brush panels each include flat fingers, a contiguous central region, and a brush shaft opening cut to match contours of the upright shaft. The horizontal cloth brush panels rotate in a reverse rotation with a direction of travel of a vehicle, and can be mixed and matches with various sizes and shapes.

A rotating brush for a vehicle washing system, comprising: i) a shaft (2) rotatable about a rotation axis (20) thereof; ii) a first annular support means (31) surrounding a first section (21) of said shaft (2) and comprising a first group (310) of longitudinal seats; said first support means (31) extending along the rotation axis (20) between a first and a second base (316, 317); let a first direction (318) of travel of the first group (310) of longitudinal seats be defined by the first towards the second base (316, 317), each of the longitudinal seats of the first group (310) comprising a first and a second end (312, 313); iii) a first set (41) of cleaning elements engageable in the first group (310) of longitudinal seats.

A surface of a workpiece is treated by rotating about an axis a brush having a multiplicity of radially projecting bristles with tips engaging a surface of a workpiece to be treated while positioning a stop nonrotatable with the brush in engagement with the bristles radially inward of the stop so as to rearwardly deflect the bristles prior to contact with the workpiece and thereby store kinetic energy in the bristles so that as the bristles pass the stop the kinetic energy is released and the bristles spring elastically forward and percussively strike the workpiece surface. A roughness of the workpiece surface is determined and the stop is positioned radially relative to the axis or the brush is positioned relative to the workpiece at a spacing in accordance with the determined roughness.

A brush roll configured to support a material web, in particular a web of corrugated board, comprises a roll core and arcuate shells, which are each arranged on the roll core and comprise bristles arranged on the outside. The brush roll further has fastening assemblies configured to fasten the arcuate shells to the roll core. Each of the fastening assemblies has a fastening body, which is locally fastened to the roll core, which locally fastens at least one of the arcuate shells to the roll core, which has a foot part, connected to the roll core, with a bottom, and a head part, connected to the foot part, with a lower side facing the roll core, said lower side forming at least one lower wedge face for engagement with at least one of the arcuate shells.

The invention relates to a brush device for brushing, combing, grooming, massaging or detangling, in particular for the coat and skin care of domestic animals, comprising a cassette holder for receiving a brush cassette having a drivable brush belt. The cassette holder and the brush cassette are designed in such a way that the brush cassette can be inserted into, and removed again from, the cassette holder.

A component for a vehicle wash system includes a frame and a hub portion rotatably secured to the frame. The hub portion includes an axis of rotation and an outer surface. A plurality of media elements are secured to the hub portion. The media elements include a flexible, self-supporting material such that the plurality of media elements can retain substantially the same shape when the hub portion is rotating at both high and low RPMs. The plurality of media elements are secured to the hub portion in a plurality of spaced apart rows that extend in a direction of the axis of rotation. Each of the plurality of spaced apart rows extending in a generally arcuate path along at least a portion of the hub portion.

A vehicle wash system includes a vehicle treatment area and an overhead frame portion supporting a pair of side brushes. The side brushes are configured to treat the lateral sides of the vehicle and may also treat the front and back of the vehicle. The side brushes are configured to pivot between a vertical position and an outwardly angled position, in which the side brushes are generally aligned with the side glass of the vehicle windows. The side brushes may travel along the side of the vehicle in both the vertical and pivoted orientations. The side brushes may make multiple passes along the side of the vehicle, and the side brushes may change orientation during or between passes to treat different segments of the vehicle. The side brushes may be pivoted at a side mirror location of the vehicle.
