Abstract
A rotary cloth roll assembly for treating the surfaces of the tires on one side of an automobile as it proceeds along a predetermined path of travel comprises a rotary shaft having a longitudinal axis parallel to the path of travel, a positive stop abutment secured to the shaft and a plurality of aligned replaceable cartridges mounted upon the shaft for rotation therewith and bearing against the abutment. Each cartridge includes a series of engaging spacers, with each spacer having at its center an opening generally conforming to the shaft for rotation therewith and for preventing rotation of the spacers relative to the shaft. Each spacer has first and second sides, the first side being generally flat and having an annular groove therein and the second side having thereon a generally rectangular locating shoulder and an annular locating rim. A series of flexible non-woven cloth discs of synthetic fibers are disclosed, each disc having at its center a non-circular opening conforming to the generally rectangular shoulder of the spacers for assembly upon each of the spacer shoulders respectively and rotation therewith and for preventing rotation of the discs relative to the spacers. A removable fastener on the shaft secures the spacers to the shaft with the locating rim on each spacer interlocked with an annular groove of an adjacent spacer and for securing the flexible discs between the spacers. The invention further includes the method of making a cloth roll cartridge.
