Abstract
Abstract Apparatus is provided for applying gasket-forming material to workpieces. The apparatus includes a supply of the gasket-forming material under pressure with a nozzle communicating with the material for directing the material to mateable surfaces of workpieces which are to be joined to mateable surfaces of other workpieces. Means are provided to move the nozzle over the mateable surfaces and to supply beads of the gasket-forming material thereto. The means include a track positioned in a predetermined location relative to the mateable surface, with means connected to the nozzle and the material supply and movable along the track to move the nozzle in the desired direction. When the connecting means makes one trip around the track, a complete bead of the gasket-forming material is applied to the mateable surface of the associated workpiece from the nozzle. Another workpiece is then moved into position and the bead-applying process is repeated. The nozzle can be moved in the same direction around the mateable surface each time, or the direction can be reversed for the mateable surface of the next workpiece.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
Apparatus for applying a bead of gasket-forming material along a mateable surface of a workpiece, said apparatus comprising a track located in a predetermined position relative to the mateable surface of the workpiece, said track having a shape generally the same as the shape desired for the bead to be applied to the mateable surface of the workpiece, a gasket-forming material nozzle carried by said track and directed toward the mateable surface of the workpiece, means for supplying gasket-forming material to said nozzle, and means for moving said nozzle along the track and along a determined path relative to the workpiece.
Claim 2
Dependent Claim
101 words
Apparatus for applying a bead of gasket-forming material along a mateable surface of a workpiece, said apparatus comprising a track located in a predetermined position relative to the mateable surface of the workpiece, said track having a shape generally the same as the shape desired for the bead to be applied to the mateable surface of the workpiece, a gasket-forming material nozzle carried by said track and directed toward the mateable surface of the workpiece, means for supplying gasket-forming material to said nozzle, and means for moving said nozzle along the track and along a determined path relative to the workpiece.
Claim 3
Dependent Claim
