Abstract: An animal halter is integrally formed from a single length of line, having all segments of the halter defined by a preordained sequence of nonslip knots to join lengths of the line into the particular configuration of the halter. Nonslip knots eliminate the need for stitching or external hardware to join the various segments of line together to achieve the desired configuration for the halter, reducing the wear occurring at such junction points when the halter is under stress. Nose band and neck band segments have double lengths of line to give the halter additional strength. A double looped segment is formed together with the chin piece to provide for the attachment of a lead to enable the halter to be used as a hackamore.

Abstract: The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material.

Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle.
