Description

Technical Field

[0001] The utility model relates to a pipe making device, more specifically, a fire hose bonding device. Background Art

[0002] Typically, the fire hose blank is bonded to the hose using steam heating from within the hose. The steam's heat melts the adhesive on the hose's exterior, and the steam's pressure forces the adhesive to adhere tightly to the blank, forming the bond. This forming method, however, does not allow for continuous production, limiting hose lengths to 40 meters. This method also results in low production efficiency and significant process losses. It also requires the installation of a specialized steam boiler and specialized boiler operators, increasing safety risks. Utility Model Content
