Title:
METHOD FOR MANUFACTURING ELONGATED BODY
Document Type and Number:
WIPO Patent Application WO/2020/054778
Kind Code:
A1
Abstract:
This method for manufacturing an elongated body is characterized by having been invented in order to manufacture an elongated body having good slipperiness, bendability, and flexibility, with little contamination of the surroundings, the elongated body being constituted from a plurality of electric wires and/or tubes, a coating layer comprising at least an intermediate layer and an outermost layer, a resin film having a density ρ1 of 0.2 g/cm3 to 1.8 g/cm3, and a value PV1, which is a surface PV value, of 5 µm or more, being used in the intermediate layer, and a resin film having a density ρ2 of 1.2 g/cm3 to 2.5 g/cm3 being used in the outermost layer, the method including at least a step for coating the elongated body with the coating layer, and a step for securing the position of the plurality of electric wires and/or tubes, a value PV2, which is the PV value of the surface of the outermost layer, satisfying formulae (1) and (3) when being equal to or less than 5 µm, and satisfying formula (2) and (3) when PV2 is greater than 5 µm. PV1 – PV2 ≥ 2 µm (1)
PV2 – PV1 ≥ 0 µm (2)
ρ2 – ρ1 ≥ 0.1 g/cm3 (3)
