Portable manufacturing method for manufacturing flexible insulated duct

摘要

A method of manufacturing flexible insulated duct includes wrapping a substantially flexible tubular core with a layer of insulation. A substantially flexible outer layer is wrapped about the layer of insulation such that longitudinal edges of the outer layer circumferentially overlap to define a longitudinally extending seam. The overlapping longitudinal edges of longitudinally extending seam in the outer layer are bonded together, thereby forming the flexible insulated duct. The flexible insulated duct is then cut to a discrete length and installed at a job site.

1. A method of manufacturing flexible insulated duct within a truck, the method comprising:
providing a substantially flexible tubular core traveling in a longitudinal direction within the truck; providing a layer of insulation traveling in the same direction within the truck as the substantially flexible tubular core; passing the substantially flexible tubular core and the layer of insulation concurrently through a first collar within the truck, wherein the layer of insulation exits the first collar in a U-shape around the substantially flexible tubular core; passing the substantially flexible tubular core and the layer of insulation concurrently through a second collar within the truck, wherein each of two longitudinal edges of the layer of insulation overlap to form a seam within the second collar, the layer of insulation exits the second collar in a cylindrical-shape around the substantially flexible tubular core to form an insulated core, wherein the second collar is downstream from the first collar; passing the insulated core downstream from the second collar; passing the insulated core and a substantially flexible outer layer concurrently through a third collar within the truck, wherein each of two longitudinal edges of the outer layer overlap under a heat source to form a seam within the third collar, the substantially flexible outer layer exits the third collar in a cylindrical-shape around the insulated core, wherein the third collar is downstream from the second collar, thereby forming the flexible insulated duct within a truck; and cutting the flexible insulated duct within the truck to a discrete length.
