Claims19
A multi-layered flexible taping material, comprising:
- a rubber layer, wherein the rubber layer comprises a plurality of at least three polychloroprene polymer sheets, each sheet having a first end, a second end, and a length therebetween;
- a heat sensitive adhesive layer comprising polyurethane polymer;
- and
- a layer of release paper, wherein the adhesive layer covers substantially an entire lower surface of the rubber layer and is disposed substantially between the rubber layer and the release paper, wherein each sheet has its first end or its second end spliced together with the first end or the second end of an adjacent sheet such that the length of the rubber layer is substantially equal to or greater than the total lengths of the at least three sheets.

A method of manufacturing a multi-layered taping material, comprising:
- providing a first sheet of polychloroprene rubber, a second sheet of polychloroprene rubber, a third sheet of polychloroprene rubber, a sheet or film of heat-sensitive polyurethane adhesive, and a sheet of release paper, wherein each of the first sheet, the second sheet, and the third-sheet of polychloroprene rubber comprises a first end, a second end, an upper surface and a lower surface, and the sheet or film of heat-sensitive polyurethane adhesive comprises an upper surface and a lower surface;
- placing the second end of the first sheet of polychloroprene rubber adjacent to the first end of the second sheet of polychloroprene rubber;
- splicing together the second end of the first sheet of polychloroprene rubber and the first end of the second sheet of polychloroprene rubber;
- placing the first end of the third sheet of polychloroprene rubber adjacent to the second end of the second sheet of polychloroprene rubber;
- splicing together the first end of the third sheet of polychloroprene rubber and the second end of the second sheet of polychloroprene rubber;
- laminating the upper surface of the sheet or film of heat-sensitive polyurethane adhesive to the lower surfaces of the first, second, and third sheets of polychloroprene rubber;
- and
- attaching the sheet of release paper to the lower surface of the heat-sensitive polyurethane adhesive.
