This machine is designed to coat the top surface of a part as opposed to the other machines in the line, which coat the bottom surface. This allows the coating of parts fed to the machine by conveyers, and also allows the dry side of the part to be handled as it exits the machine. This simplifies the handling of parts, and also allows the gluing process to be automated. Top feed rate is approximately 100 FPM (variable speed)

The VSF sheet feeder is an accessory device that can be used with either a Schaefer cementer of any other major brand (Potdevin, Gluefast) of gluing machine. The VSF-1 feeds paper sheets into the gluing station automatically, and eliminates the need for an operator to stand in front of the machine to load sheets. The machine holds approximately 300 sheets of paper, and can feed either on a signal from the operator, or on an automatic timed cycle. The machine picks up the sheets by means of suction cups, lifts them, then indexes forward and down to insert the sheet into the gluer.

This machine is used for coating of hotmelt adhesives on leather, fabric, sheet goods, foam, plastics, and many other parts. It is able to handle the majority of hotmelt adhesives (except PUR hotmelts), and can apply either pressure sensitive types (remain tacky after cooling) or types which are dry to the touch and are re-activated by heat. Parts can be handled immediately as they exit the machine, since the glue layer cools almost instantly after coating.
