摘要： A method for continuously manufacturing a reinforced flexible hose (100), in particular a garden hose, comprising the steps of providing a semifinished hose (125) including at least one inner layer (110) and at least one textile reinforcing layer (120) wound on the outer surface thereof and extruding a thermoplastic polymer material onto the semifinished hose (125) to form a cover layer (130). The extruding step is accomplished by an extruding die (31) having a central bore (34) defining a forwarding axis (X) for housing the semifinished hose (125) and a peripheral channel (35) including a slanted tubular portion (42') and a substantially horizontal tubular portion (42") in correspondence of the outlet (37) thereof. The extruding step is accomplished by putting the central bore (34) under vacuum to draw the cover layer (130) in close contact with the semifinished hose (125). The thickness (T) of the extruded tubular film (130) is of 0,05 mm to 0,35 mm. The absolute pressure in the central bore (34) is no lower than 250 mmHg. The invention also relates to a production line and an extruding station to perform the method, as well as to a hose obtainable thereby.
