Abstract: A rotary finishing tool, such as a buffing pad, utilizes a connector assembly for demountable attachment to a powered rotary backing plate. The finishing tool is attached to the front face of a backing disc and the rear face of the backing disc includes a first piece of the connector assembly, the second piece of which is carried by the backing plate. The first and second connector pieces include complementary driving surfaces and complementary locking surfaces which respectively interengage in response to linear movement bringing the two connector pieces together and relative radial movement between the locking surfaces which are preferably resiliently biased.

Abstract: A back-up plate is provided for a reversible double-sided rotary buffing pad. The back-up plate is attached directly to the output shaft of the power buffer and the buffing pad is attached to the back-up plate and, when attached, circumferentially spaced fingers on the outer edge of the back-up plate bear on the unused buffing face and prevent excess flexing and premature fracture and failure of the backing disk on the interior of the pad that supports the oppositely disposed buffing faces.

Abstract: A rotary foam buffing pad is provided with a concave working face which allows the operator to provide true graduated surface contact in applying polish, buffing or glazing compounds, while containing the polishing compound against centrifugal force which would otherwise result in splattering of the compound. The manner in which the concave working face is formed and in which the edge face is formed and dressed results in dynamic balancing of the pad and reducing vibration and operator fatigue. The working surface forming and pad finishing operations further provide a velvetized texture to the pad working surfaces which further enhances the polishing or finishing process.

Abstract: A rotary surface finishing tool includes a generally circular body of a finishing material, such as polymeric foam, the peripheral edge of which is wrapped around the outer edge of a circular cup-shaped backing plate. The plate is subsequently crimped over the edge of a locking ring to capture the edge of the foam material therebetween. Other types of finishing material, such as tufted wool, including a backing with a flexible peripheral edge can also be mounted to a backing plate using the crimping techniques described herein.

Abstract: A polymeric foam finishing pad is made by attaching an array of foam fingers to a suitable support substrate. The foam fingers are attached to the substrate in a continuous strip of interconnected fingers or may be individually inserted into a support substrate and attached to the substrate by an adhesive layer. Each of the foam members is preferably formed in and cut from an advancing foam strip and folded and inserted into a preformed opening contained in the support substrate, such that each foam member forms a pair of fingers that extend from the front face of the support substrate. The outer tip of each foam finger may include a pair of slits extending into the foam member from the outer tip to divide each outer tip into a plurality of contact tips, thereby increasing the amount of surface contact between the finishing pad and the surface being finished. The tips of the fingers may also be provided with abrasive particles to provide a more aggressive pad finishing surface.

Abstract: A polymeric foam finishing pad is made by attaching a dense array of individual foam members to a suitable support substrate. The foam members are individually inserted into a support substrate and attached to the substrate by an adhesive layer. When making the foam pad, each of the foam members is preferably folded and inserted into a preformed opening contained in the support substrate, such that each foam member forms a pair of fingers that extend from the front face of the support substrate. The outer tip of each foam finger may include a pair of slits extending into the foam member from the outer tip.

Abstract: A polymeric foam finishing pad is made by attaching a dense array of individual foam fingers to a suitable backing substrate. The fingers may be individually attached to the substrate or attached to the substrate by an intermediate foam strip to which the fingers are integrally joined. When making a circular rotary buffing pad, the foam strip is preferably attached to the substrate in a spiral pattern.

Abstract: An apparatus for cleaning a buffing pad mounted on a rotary powered buffing machine is adapted to be adjustably mounted by a plurality of support legs within an open container containing a liquid cleaning solution. The buffing pad is placed in an upper enclosure that can be adjusted in size to correspond to buffing pads of varying thickness. The bottom of the enclosure includes a water wheel mounted for engagement by the buffing pad and rotatable between the enclosure and a point below the level of cleaning solution in the container, such that powered operation of the buffing machine and rotation of the pad drives the water wheel to deliver cleaning solution to the pad enclosure to clean accumulated wax, dirt and other materials from the pad. The device makes use of a series of rotatable cleaning wheels of the type used in prior devices which are also driven by the buffing pad and assist in loosening and removing accumulated materials from the buffing pad.
