US Patent:

50386638, Aug 13, 1991

Filed:

Sep 16, 1983

Appl. No.:

6/532708

Inventors:

Walter A. Plummer - Sherman Oaks CA

International Classification:

D04C 112

US Classification:

87 6

Abstract:

This invention relates to protective and appearance sleeving, and more particularly to improved expandable-contractible braided sleeving having a pull cord extending lengthwise of its interior one end of which is attachable to an object to be enshrouded while the sleeving is being assembled thereover. The pull cord may comprise a strip of high strength material imprintable with indicia.

Appl. No.:

7/072216

Laurence R. Klein - Torrance CA
Walter A. Plummer - Santa Ana CA

Assignee:

The Zippertubing Co. - Los Angeles CA

International Classification:

H01B 734

US Classification:

174 36

Abstract:

An electrically conductive removable jacket is provided for wire bundles or the like. The jacket comprises a flattened knitted metal wire tube with a strip of hook and loop fastener stitched along each longitudinal edge so that a tubular jacket is formed by overlapping the edges and securing the fasteners. Plural strips of hook and loop fastener assure that the jacket can be kept electrically "closed" regardless of the size of bundle encompassed. A resilient gasket is provided along one edge of the conductive jacket for making electrical contact with the opposite edge. The conductive jacket may be secured along one edge to one edge of a flexible electrically insulating jacket having fastening means along each edge for forming a tubular insulating jacket. The insulating jacket is inside of the conductive jacket.

Appl. No.:

6/817868

Inventors:

Walter A. Plummer - Sherman Oaks CA

International Classification:

D03D 302

US Classification:

29446

Abstract:

Disclosed is a method of making pre-expanded braided sleeving from flexible strands of either conductive or nonconductive filaments, or a combination thereof, along with entrapped warp filaments of heat shrinkable material. The warp filament material is commonly known as heat reactive material and, when briefly subjected to heat below its fusion temperature, shrinks in the order of 30% to 50% of its length and very substantially expands the sleeving thereby greatly expediting the assembly thereof over an elongated object. Thereafter the sleeving is readily contracted into a snug fit with the object upon being tensioned between its opposite ends.
