ABSTRACT:
A hand held, trigger operated, adhesive hot melt gun slidably mounts a base plate parallel with the gun axis with the plate spring biased forwardly in the direction of a hot melt adhesive discharge nozzle at the end of the gun remote from the trigger. An L-shaped extrusion tip carried by said nozzle includes a series of small diameter holes forming a vertical array within an upright leg which leg contacts an edge of a panel during sweep of the extrusion tip across the edge to deposit linear beads of melted adhesive thereon. The band, which may be mounted within a magazine on the base plate, feeds across the back edge of the extrusion tip to contact the adhesive coated panel edge downstream of the adhesive application point at a point where it is tacky. A spring biased pressure roller mounted to the base plate or otherwise presses the band against the tacky adhesive at this point during relative sweep of the apparatus along the edge of the panel. The apparatus may be removably mounted to a table and maintained fixed while the panel edge is run across the table top with its edge pressed against the extrusion tip and one or more pressure rollers.
