Abstract
The present invention is related to an apparatus and method for a carrier rope for use in the transport of paper webs in paper threading machine systems. The carrier rope constructed in accordance with the invention comprises a multi filament yarn assembly (A) having an initial twist, a composite yarn assembly (B) comprising mono filament yarn imparted around the multi filament yarn assembly via a second twist, wherein the multi filament yarn assembly (A) is not further twisted, a braided plait assembly (C) comprising a braid of composite yarn assemblies, and a carrier rope (D) comprising a braid of braided plait assemblies.
Claims31
A method of manufacturing a carrier rope, comprising the steps of:
- imparting a twist to a plurality of multi filament yarns forming a multi filament yarn assembly;
- imparting a second twist to monofilament yarn around the multi filament yarn assembly forming a composite yarn assembly, wherein the multi filament yarn assembly is not further twisted;
- braiding a plurality of the composite yarn assemblies forming a braided plait assembly;
- and
- braiding a plurality of the braided plait assemblies forming a carrier rope.
A method of manufacturing a carrier rope comprising the steps of:
- imparting a twist to four ends of 700 dtex multi filament nylon 6.6 in equal Z and S twist yarns forming a multi filament yarn assembly;
- imparting a second twist to a single monofilament nylon 6 yarn around the multi filament yarn assembly forming a composite yarn assembly, wherein the multi filament yarn assembly is not further twisted;
- braiding eight Z twist ends and eight S twist ends of the composite yarn assembly forming a braided plait assembly;
- braiding eight ends of the braided plait assemblies forming a carrier rope;
- applying a protective coating to the carrier rope;
- and
- heat setting the carrier rope.
