摘要：
A method for manufacturing a kink- resistant tube having drainage holes is provided. A wire (2) is coated with plastic material (4) and wound around a mandrel (6) forming a plurality of windings. The wound coated wire is heated until the plastic coating material melts and bonds the wire windings to form a wire - reinforced sheath having wire- containing sections and non-wire containing sections. Alternatively, a coated or non- coated wire is wound around a mandrel together with separate polymer filament material and then heated. A filament having an elongated cross - section may be employed with the major axis of the elongated cross - section substantially parallel to the longitudinal axis of the sheath. At least one non-wire containing section is identified by passing light through at least one wall of the wire - reinforced sheath. Image capture and analysis via an optical system and microprocessor automatically identify regions to target a drill for forming holes in the non-wire containing sections.
