Patent ID: 10035302

Abstract:
A hand-held, portable floor seam sealing device is provided that has universal application to many commercially available floor sheet materials, including vinyl, linoleum, rubber, sport floors as well as other flooring sheet materials. The device employs a seam sealing welding gun and a nozzle of unique configuration defining a cavity bounded by a front end with two rows of at least eight air jet apertures directed toward a gap formed between forwardly projecting glue stick receiving flanges. The nozzle also through has a downwardly directed fin that terminates in a multiplicity of downwardly directed air jet discharge apertures. As the device is moved along the length of a seam between adjacent sheets of flooring, hot air from the apertures in the downwardly directed air jet discharge ridge preheats the portion of the seam into which sealant is about to be dispensed while hot air from the air jet apertures in the front end of the nozzle melts the sealant.
