Beschreibung
Zusammenfassung:	Provided are dispensing devices and methods for a filament adhesive. The dispensing devices use a barrel including one or more heating elements, and a rotatable screw received in the barrel, the rotatable screw optionally including at least one mixing element. An inlet extends through a side of the barrel for receiving the filament adhesive, the inlet including a beveled nip point to prevent breakage of the filament adhesive as it is drawn into the barrel. An outlet at a distal end of the barrel for dispensing the filament adhesive in molten form. Using the provided dispensing devices, and optionally with the assistance of a computer, adhesives can be precisely applied to pre-determined locations on a substrate.
