Abstract
A heat and sealant delivery nozzle is constructed for sealing seams between adjacent sheets of flooring. The nozzle of the invention is formed from separate, mating sealant feeding and hot air conducting members that fit to and are secured together. The two part construction of the nozzle produces first and second enclosed plenum chambers therebetween with a series of ducts and passages that preheat both the groove in the flooring that is to receive molten sealant, and the sealant itself. Furthermore, although the pattern of ducts, passages, and cavities within the finished nozzle is quite intricate, the ducts, passageways, and ports are formed without great difficulty due to the two part construction of the nozzle. Moreover, the nozzle is constructed so that the hot air does not mix with the sealant within an internal melting chamber, but rather makes contact with the molten sealant only when the sealant leaves the nozzle.
