摘要:
Magnet wire is insulated with a paper insulation sheet which is longitudinally wrapped onto the wire. The paper sheet is precoated on one side with a layer of resinous adhesive dielectric material such as a thermoplastic polyester. The outside surface of the paper sheet has the resinous coating applied thereto and solidified prior to the time that the paper is wrapped onto the wire. Just prior to applying the paper to the wire, an edge of the resin coating is heated sufficiently to locally remelt the resin. The remelted edge is then overlapped by the opposite edge as the coated paper is wrapped onto the wire, whereby the edges of the insulation sheet are adhered together. The wrapped wire is then passed through one or more heated dies in order to remelt the entire resin coating, which remelted coating is then drawn back over the exterior of the paper layer. The wrapped wire is then passed through a water quench bath. The paper wrap is thus recoated in situ with the resin, thereby forming a continuous and uninterrupted resinous jacket on the paper and wire.
摘要:
Wrapping an article such as cable or optical fibre in wrapping material by a progressive operation in which the wrapping material is pressed along a narrow width portion to the article and then succeeding width portions are also turned around the article and pressed against it. The procedure is intermittent with each width portion turned completely against the article before turning of the next portion. This method eliminates wrinkles in the wrapping material. The process is convenient when using contact adhesive on a surface of the wrapping material.

A METHOD AND MEANS FOR REFURBISHING, CUSTOMIZING AND CONVERTING SERVICE CORD ASSEMBLIES AND THE LIKE SIMPLY, ECONOMICALLY AND WITHOUT NEED FOR TOOLS, SKILLED SERVICES OR INTERRUPTION OF SERVICE. WORN, DAMAGED, DISCOLORED OR NON-HARMONIZING CORD SHEATHS ARE QUICKLY REFURBISHED OR REPLACED WITH A NEW SHEATH OF SELECTED COLOR HARMONIZING WITH THE OLD OR SOME NEW DECORATIVE DECOR EXPENDITIOUSLY AND IN A HIGHLY PROFESSONAL MANNER. THE INVENTION TECHNIQUE AND ADVANTAGES ARE TYPIFIED BY AN APPLICANCE SUCH AS A TELEPHONE SET AND SERVICE CORD
ASSEMBLY WHEREIN A STANDARD PHONE CHASSIS AND SERVICE CORD CAN BE EMPLOYED SELECTIVELY WITH ANY OF A WIDE RANGE OF MATCHING COLORED COVER SHELLS AND SERVICE CORD SHEATHS.
