Abstract
Abstract A gasket installing device comprises a hollow frame and a guide roller rotatably mounted at a leading end of the hollow frame for rolling movement over a panel edge along which a gasket is to be installed. A presser wheel is rotatably disposed in the hollow frame and has means on its circumference for engaging and pressing the gasket against the panel edge at a position adjacent to an open side of the hollow frame. A gasket guide disposed in the hollow frame adjacent to the leading end has a passage for the gasket to pass therethrough, the passage extending at an angle to the open side. The passage has a discharge opening spaced from the above-mentioned position and from the open side. The hollow frame supports a correction roller assembly on its trailing end for correcting the installed gasket into proper disposition over the panel edge. A cutter arm is disposed in and pivoted to the hollow frame, the cutter arm having a cutter thereon and being pivotable to move the cutter blade into and out of a slot in the gasket guide across the gasket passage in response to the movement of a lever pivotally mounted on the hollow frame.
