Abstract: A glass workpiece processing apparatus, such as a glass washer, includes a frame, a pair of rails attached to and extending along the frame, a plurality of workpiece supporting rollers positioned along the pair of rails, and a pair of bearing stands rotatably supporting each roller. Each bearing stand includes a base removably attached to one rail, a bearing attached to said base which rotatably supports the roller, and a releasable bearing retaining member attaching the bearing to the base. The bearing retaining member may be a snap-on clip including locking projections engaging corresponding locking notches in the base. Alternatively, the retaining member may include a stop screw threaded through a portion of the base.

Abstract: An air flotation assembly table utilized in the application of sealant strip material to the perimeter edges of sheet material, the assembly table having a flat work surface upon which the flat sheet material, such as a glass sheet, is placed for applying the sealant strip material to successive perimeter edges thereof. The flat work surface has a plurality of spaced-apart air holes through which air is emitted to float the sheet material slightly thereabove. In combination with the assembly table there is included a vacuum cup assembly for linearly positioning the sheet material so that an edge of the sheet material is presented to the workman, the vacuum cup assembly further including a vacuum cup for adhering to the sheet material, and a lift shaft for raising and lowering the vacuum cup. The vacuum cup assembly is mounted to a carriage which is selectively actuated for linear movement by a band cylinder.

Abstract: An oven unit for heat treating sealant strip material applied to the perimeter edges of a window unit includes an oven box having a pair of spaced-apart sidewalls and an upstream end for receiving the window unit and a downstream end for egress of the window unit after heat treating. The window unit is conveyed through the oven box by a plurality of rollers extending between each sidewall and arranged from the entrance end to the exit end. Interspersed among the rollers and located immediately adjacent and below the window unit are a plurality of lower emitters for generating and directing radiant heat energy upon the sealant strip material. An upper row of spaced-apart emitters also directs radiant heat energy upon the sealant material.
