  • Straight ply and angle ply comprising metallic monofilaments
    Patent number: 11607912
    Abstract: A ply (16, 18) comprises metallic monofilaments (46?, 46?). Each monofilament (46?) of a first group has a positive torsional elastic deformation in a first direction about its main axis (G). Each monofilament (46?) of a second group has a negative torsional elastic deformation in a second direction about its main axis (G). The absolute value of the torsional elastic deformation C of each monofilament (46?, 46?) is such that |C|?6 turns per ten metres. The mean S of the torsional elastic deformations of the monofilaments (46?, 46?) of the ply (16, 18) is such that ?0.25 turn per ten metres?S?+0.25 turn per ten metres. The monofilaments (46?, 46?) are arranged next to one another so as to alternate one or more monofilaments (46?) of the first group with one or more monofilaments (46?) of the second group.
