In one pass through the apparatus (10), a sealed seam in a protective barrier fabric joint (14), using a curable adhesive sealant (84), is provided along a predetermined and specified length of the joint (14). The preferred adhesive (84) is a silicone, most preferably a two-part, thermosetting silicone elastomeric adhesive. Also provided are mixing dies (26) for use, inter alia, in the process which are especially suited for applying the two-part adhesive sealant (84). In addition, variable-residence-time curing apparatus, which effects variable, controlled, desired cures of the adhesive, all in a one-pass operation, is provided, together with precise metering pumps, especially suited for supplying the seam sealing adhesive (84) in the process of the invention.</p> |
