Exemplary methods for manufacturing a wire and resultant wires are disclosed herein. The method includes extruding a receptor cross-linkable polymer that is substantially free of curing agent about a conductive core and extruding a donor polymer in association with a curing agent. The method includes disposing the donor polymer about the receptor polymer and conductive core to create a multi-layer wire pre-product. The method also includes heat curing a multi-layer wire pre-product to form a wire.

Damage of the outer surface of a rubber hose due to friction can be prevented while the sealing performance and the productivity are ensured. The following components are provided: a pipe 11 whose one end is connected to a vulcanization pipe and in which pressed liquid is pumped from an inlet 11a disposed at the side face of the other end side; an annular member 12 which is attached to the pipe 11 so as to close an opening of the other end side of the pipe 11, and includes a hole 12a whose diameter is larger than the outer diameter of a rubber hose and in which the rubber hose passes through; and a pump which pumps more liquid than the liquid discharged outside the pipe 11 through the gap between the hole 12a and the rubber hose into an inlet 11a.

[Problem] To provide a manufacturing method with which a cured resin film can be manufactured at high yield, and which effectively prevents the occurrence of defects such as wrinkles in the cured resin film.

[Solution] Provided is a cured resin film manufacturing method comprising: a first step in which an undried resin film is formed on a support, the undried resin film comprising a heat curable resin composition containing a curable resin and a solvent; a second step in which a curable resin film having a loss of 0.5-7 wt % on heating is formed by drying the undried resin film which has been formed on the support by using a float method to convey the undried resin, which is in the state of having been formed on the support, in a drying device; a third step in which a cured resin film is formed by heat curing the curable resin film; and a fourth step in which the support is detached from the cured resin film.
