Abstract
A method of dispensing an adhesive on a substrate includes flowing an extrudate of the adhesive through a flow control valve and an application nozzle, and introducing a non-adhesive fluid into the extrudate within the flow control valve upstream from a distal end of the application nozzle such that the non-adhesive fluid interrupts a boundary layer of the extrudate and a non-contact cut of the extrudate is provided. The non-adhesive fluid can be air that forms a bubble in the extrudate of the adhesive flowing through the application nozzle and adhesive dispensed onto the substrate is free of a string and/or a teardrop.
