Abstract: A system for applying adhesive to the peripheral edge of a window glass includes a brush which is held stationary while the window glass is moved with respect to the brush to apply the adhesive. The brush includes a plastic sleeve which exposes only a specified portion of the bristles of the brush. After the bristles have worn, the brush is moved to a cutting station where a portion of the sleeve is removed to expose another portion of the bristles. This operation continues until there is no material left on the sleeve to trim. At this point, the brush is discarded and replaced with a new brush automatically. Rather than have the window glass move with respect to the brush, the brush can be moved with respect to the window glass if desired.

Abstract: An improved dispensing apparatus is disclosed which is specifically adapted to provide a supply of wiping material for use in conjunction with the application of coatings to motor vehicle window glass. The dispensing apparatus of the present invention incorporates a spool carrying a substantial supply of the required wiping material and associated support apparatus for supporting the spool in close proximity to its area of use. The support apparatus enables quick and easy replacement of the spools as well as providing a controlled resistance to rotational movement of the spool during operation of the apparatus.

Abstract: There is disclosed an automatic fastener driving system suitable for robotic applications utilizing a modified fastener driver having a unique detection mechanism in the head of the driver working in combination with a pneumatically operated advance and retract mechanism, and control circuitry, to detect when a fastener is present in the driver, to advance and drive the fastener into the workpiece, and to then automatically retract therefrom.
