摘要

process of applying a thermofluid adhesive to a substrate and apparatus for applying a thermofluid adhesive to a series of substrates an extrusion process and apparatus for depositing precise, usually small amounts of extrudate (4) for adhesion to a substrate (1) comprising an extruder (2) positioned next to the substrate (1) and a hot gas jet (6) directed at the extruder (4) between the extruder (2) and the substrate (1) in order to retain the properties adhesion between the extrudate (4) and the substrate (1).
