Abstract:
The invention concerns a line, in particular a fishing line, consisting of a core (10) and a sheath (20) surrounding the core (10). Both the core (10) and sheath (20) are made up of high-strength filaments (11, 12, 21, 22). The filaments (21, 22) forming the sheath are wound round the core (10). The bundle of filaments (11, 12, 21, 22) is bonded together preferably by a fusion-adhesive yarn (19) laid essentially parallel to the filaments (11, 12) forming the core (10). This enables a fishing line to be produced which meets the most demanding requirements and yet is inexpensive. Forming the sheath (20) by winding filaments round the core (10) and then bonding offers considerable cost savings over the prior art method of braiding the sheath over the core.
Abstract:
Provided are an annular concentrically-twisted bead cord, which is reduced in weight while retaining satisfactory manufacturing and handling properties, and a vehicular tire employing the bead cord. The annular concentrically-twisted bead cord (2) has a sheath layer (13) formed by winding side wires (12) helically around a metallic annular core (11). The side wires (12) are constituted by wrapping a pair of steel wires (22) around a side wire body (21) made of aramid fibers.
