Abstract

A car wash brush is constructed using elements of pleated synthetic material. In one form, radially-pleated fabric discs are stacked on a shaft. In another form, a single length of material is laterally pleated and punched to form a continuous pattern of holes along one edge, and assembled onto a spring or flexible cable which can be wrapped around a rotatable drive shaft.

Claims

1. A rotary carwashing brush comprising:

an elongate, rotatable support structure defining an axis of rotation;

brush means mounted on such structure for rotation therewith about said axis and having an outer perimeter;

said brush means comprising multiple axially spaced-apart, circumferentially continuous revolutions of a non-woven, water-carrying, synthetic material into which shallow regularly alternating pleats of approximately two inches in width have been preformed and permanently set by heat and pressure;

the pre-pleated construction of said revolutions being such that the pleats extend radially of said axis substantially fully from said axis to said outer perimeter and provide sufficient body to said brush means to remain substantially radially extended when stationary; and

means for rotating said support structure and brush means against the wet surface of a vehicle being washed.

2. The rotary carwashing brush defined in claim 1 wherein the radially outermost, circumferential edges of the revolutions are pre-frayed.

3. The rotary carwashing brush defined in claim 1 wherein the synthetic material is needle-punched synthetic felt.
