- A method of forming a heated hose (1200, 1600) comprising: extruding a continuous web of plastics material of uniform width and of thin cross section from a first extruder of a hose making apparatus; helically winding the extruded web about a mandrel or at least one rotating rod of the hose making apparatus to form a wall (1270, 1670) of the heated hose about a central axis of the heated hose (1200, 1600); feeding a first heating wire (1290, 1690) into a second extruder of the hose making apparatus; extruding a first continuous bead of plastics material (1280, 1680) around the first heating wire (1290, 1690) from the second extruder of the hose making apparatus such that the first extruded bead (1280, 1680) comprises the first heating wire (1290, 1690) at a first location within a cross-section of the first extruded bead (1280, 1680); helically winding the first extruded bead (1280, 1680) onto and about an external surface of the wall (1270, 1670) of the hose (1200, 1600) formed from the helical winding of the extruded web to provide the wall (1270, 1670) a first support helix (1280, 1680) that incorporates the first heating wire (1290, 1690); and exerting tension on the first heating wire (1290, 1690) as the first heating wire (1290, 1690) is fed into the second extruder to draw down the first heating wire (1290, 1690) toward the central axis of the hose (1200, 1600) such that the first heating wire (1290, 1690) migrates radially inward within the first extruded bead (1280, 1680) from the first location within the cross-section of the first extruded bead (1280, 1680) to a second location within the cross-section that is closer to the wall (1270, 1670) of the hose (1200, 1600) and closer to the central axis than the first location. extruding a continuous web of plastics material of uniform width and of thin cross section from a first extruder of a hose making apparatus; helically winding the extruded web about a mandrel or at least one rotating rod of the hose making apparatus to form a wall (1270, 1670) of the heated hose about a central axis of the heated hose (1200, 1600); feeding a first heating wire (1290, 1690) into a second extruder of the hose making apparatus; extruding a first continuous bead of plastics material (1280, 1680) around the first heating wire (1290, 1690) from the second extruder of the hose making apparatus such that the first extruded bead (1280, 1680) comprises the first heating wire (1290, 1690) at a first location within a cross-section of the first extruded bead (1280, 1680); helically winding the first extruded bead (1280, 1680) onto and about an external surface of the wall (1270, 1670) of the hose (1200, 1600) formed from the helical winding of the extruded web to provide the wall (1270, 1670) a first support helix (1280, 1680) that incorporates the first heating wire (1290, 1690); and exerting tension on the first heating wire (1290, 1690) as the first heating wire (1290, 1690) is fed into the second extruder to draw down the first heating wire (1290, 1690) toward the central axis of the hose (1200, 1600) such that the first heating wire (1290, 1690) migrates radially inward within the first extruded bead (1280, 1680) from the first location within the cross-section of the first extruded bead (1280, 1680) to a second location within the cross-section that is closer to the wall (1270, 1670) of the hose (1200, 1600) and closer to the central axis than the first location.
