Abstract
Apparatus for supporting a window being moved parallel to a pair of opposite edges thereof, particularly a double-pane window having fresh sealant coated along its leading and trailing edges, comprises two sets of rollers spaced apart laterally beneath the window with the rollers of each set longitudinally spaced in the path of travel of the window. Detectors responsive to the leading and trailing edges of the window selectively actuate the rollers to their respective upper positions after passage of a leading edge of the window thereby, and to respective lower positions prior to passage of a trailing edge thereby. This avoids soiling the rollers by the fresh sealant, with consequent soiling of subsequent windows. The windows may be supported midway of its side edges by a moving carriage, and guides for the side edges may be provided. Upstream and downstream detectors for each roller are described, particularly pneumatic detectors with an AND cell for controlling actuation of a roller.
