Abstract: Apparatus and a method for sealing of protective barrier fabric seams in otherwise impermeable articles such as garments, footwear, surgical gowns and the like, are provided, the sealed seams maintaining the imperviousness of the article, including seamed joints, to water, body fluids, pathogens and chemicals. In one pass through the apparatus, a sealed seam in a protective barrier fabric joint, using a curable adhesive sealant, is provided along a predetermined and specified length of the joint. The preferred adhesive is a silicone, most preferably a two-part, thermosetting silicone elastomeric adhesive. Also provided are mixing dies for use, inter alia, in the process which are especially suited for applying the two-part adhesive sealant.

Abstract: A nozzle assembly adapted for repeatably positioning the nozzle in a precise relationship to an article and method for using it in a seam-sealing operation, the nozzle assembly comprising a nozzle, an alignment plate, and an arm forming a unitary nozzle assembly, and an air conduit for connecting the nozzle to a source of pressurized air. The nozzle assembly may further comprise a base for mounting the integral nozzle unit alignment plate, and a linear actuator connected to the base for moving the base along a linear path from a first, operating position to a second, standby position. The nozzle may be oriented to avoid visually obstructing the article receiving air flow.
