Abstract:
1. A contact nozzle for coating at least one elastic strand with an adhesive, a first strand having a periphery with an upper surface and moving in a machine direction, the contact nozzle comprising: a nozzle body including a front side, a rear side, and a first V shaped notch for receiving the first strand and extending between said front and rear sides; a first adhesive passage formed in said nozzle body and terminating at a first adhesive orifice communicating with said first V-shaped notch and adapted to be directed at the upper surface of the first strand to deliver the adhesive into contact with the upper surface of the first strand; a first expansion chamber formed in said nozzle body and communicating with said first adhesive orifice, said first expansion chamber sized to enable die swell of the adhesive exiting said first adhesive orifice; and a first air passage positioned proximate to said first adhesive passage and terminating at a first air orifice positioned downstream from said first adhesive orifice in the machine direction, said first air orifice being positioned above said first adhesive orifice in said nozzle body, and said first air orifice adapted to be directed toward the upper surface of the first strand and adapted to discharge air at the adhesive in contact with the first strand to cause the adhesive to spread around the periphery of the first strand.
