ABSTRACT:
This invention is concerned with apparatus for manufacturing spirally wound gaskets. The apparatus includes a pair of co-planar radially movable forming discs and independently mounted and axially adjustable guide members. The apparatus may be used either for winding gasket forming material tightly around one forming disc, or adapted for centerless winding where gasket forming material is wound in a loop around one forming disc. Where thin, wide-flanged gaskets are to be wound, the forming disc which abuts the outer periphery of the gasket is shaped so as not substantially to curve gasket forming material in the direction away from the gasket periphery and thus produce stress in the gasket. Where the apparatus is designed for centerless winding, a template adapted to be disposed between the forming discs to move in conjunction with gasket forming material may be provided, particularly for forming non-circular gaskets.
