System, nozzle and method for coating elastic strands

Abstract:

A contact nozzle for simultaneously coating a plurality of elastic strands moving in a machine direction with an adhesive is described. The contact nozzle includes a single fluid inlet for receiving the adhesive from a fluid module, a first inverted V-shaped notch, a second inverted V-shaped notch, a third inverted V-shaped notch, and a mounting surface configured to abut the fluid module when the contact nozzle is coupled to the fluid module. Each inverted V-shaped notch extends along the contact nozzle in the machine direction, has an open bottom end, a circular closed top end. Each inverted V-shaped notch includes an adhesive orifice in fluid communication with the single fluid inlet for receiving the adhesive for directing the adhesive into contact with an upper surface of an elastic strand.
