Claims11
A vehicle wash brush made of closed cell foam, comprising:
- a plurality of brush fingers or strips extending from a rigid core, for washing a vehicle, wherein the brush fingers or strips are made of closed cell foam, and wherein the brush fingers or strips are embossed, creating a series of ridges and adjacent grooves onat least an upper or opposing lower surface of the brush fingers or strips, and wherein the series of ridges and adjacent grooves are oriented in a direction generally perpendicular to the longitudinal orientation of the brush fingers or strips as they contact surfaces of the vehicle using viscous friction to clean the vehicle surfaces in the presence of water and surfactants during washing.
A method for manufacturing a vehicle wash brush made of closed cell foam, comprising the steps of:
- presenting a sheet of closed cell foam to an embossing machine, and thereby heating the sheet of foam;
- feeding the heated sheet of foam between two rollers of the embossing machine, and thereby embossing at least one surface of the sheet of foam with a series of ridges and adjacent grooves;
- cutting the embossed sheet of foam to provide a brush with a plurality of embossed fingers or strips;
- locating the brush in an automatic vehicle wash machine, with the brush fingers or strips oriented so that the series of embossed ridges and adjacent grooves are generally perpendicular to the longitudinal orientation of the brush fingers or strips as the fingers or strips contact surfaces of the vehicle using viscous friction to clean the vehicle surfaces in the presence of water and surfactants during washing.
