A manufacturing device of a fire hose is provided to bond a tube layer to a woven layer of the fire hose without cutting the fire hose into a certain length, and to preclude the use of hot steams to bond the layers. A manufacturing device of a fire hose includes a fixed rolling feeder(110) which prevents the air injected into a woven fire hose(10) to form a pressurized expansion portion from escaping towards an outer coat weaving device(210), and an moving rolling feeder(120) which prevents the air injected into the woven fire hose from escaping towards the discharging direction. A pressurizing unit(140) pressurizes the moving rolling feeder against the outer coat weaving device to maintain a constant internal pressure within the pressurized expansion portion of the fire hose. A heating chamber(150) surrounds the pressurized expansion portion of the fire hose to heat a tube layer of the fire hose. A heat unit(161) supplies a heating medium to the heating chamber. A controller(170) controls the operation of each rolling feeder and the heating chamber.
