Abstract
A hot melt adhesive dispensing system includes an adhesive cut-off module, which introduces a non-adhesive liquid medium to cut-off a hot melt adhesive stream without forming an angel hair. The adhesive cut-off module includes a spool valve assembly which is configured to move from an adhesive dispensing position to a liquid dispensing position to cut-off the hot melt adhesive stream.
