Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
In stranding apparatus of the type for SZ stranding of stranding elements in which an elongate pipe store is mounted and driven for rotation through a fixed input apertured guide disc which feeds stranding elements onto the pipe store and with a mutually rotating output apertured stranding disc which feeds the stranding elements in common to an aperture of a stranding nipple, the improvement wherein: said pipe store comprises fiber material and cured, hard resin bonding the fiber material.
Claim 2
Dependent Claim
