Abstract of the Disclosure METHOD AND APPARATUS FOR MAKING RUBBER ARTICLES Indefinite length tubular and sheeting products can be fabricated using either a continuous or step-wise method which uses a two-stage curing sequence. In the first curing stage, the center portion of a thermosetting web is fully cured leaving the lateral edges of the web in an uncured state. The uncured lateral edges are then spliced, either directly to one another, or spliced with a similar web having uncured edges to form either a flat sheet or a tubular preform having longitudinal uncured spliced seams. In the second curing stage, these uncured longitudinal splices are fully cured to form either tubular articles or flat sheeting having completely uniform physical properties throughout.
