ABSTRACT:
Insulated sheathing, such as a covering for a bundle of flexible tubes which deliver chilled beverages to a dispensing head, may be covered on their outer side by a seamless flexible sheath and similarly on the inner side of the insulation which surrounds the bundle of tubes. Flexible sheathing for the inner sheath is loaded bunched together on the outer surface of a hollow core near its downstream end. Similar larger diameter sheathing is bunched together on the upstream end of an outer concentric sleeve, whose downstream end is mounted on a slide. The downstream end of a bundle of tubes is inserted through the core, and connected to the downstream end of the inner sheathing and to the upstream end of the outer sheathing. The outer sheathing is then inverted by moving the sleeve upstream over the connected ends which are then drawn downstream together. Foam is then inserted between the two sheathings, to expand and press the outer sheathing outward, sliding against the inner surface of the sleeve as the inner sheathing presses inward and slides against the outer surface of the core. On emerging from the downstream ends of the core and sleeve, the inner sheathing is pressed against the bundle of tubes being fed through the core and the outer sheathing expands to its full diameter. The tooling and process has simpler applications, such as forming sheathed foamed coatings on pipes and forming hollow foam articles sheathed inside and out.
