Heard

A looped cord, shaped wire, or flat steel stripe with an eye in the centre through which a warp yam is threaded so that its movement may be controlled during weaving.cord mail heald A heald consisting of textile cords in which the central eye is a heald mail (see heald mail 1).doup healdSee leno weaving.flat steel healdA heald made from flat steel strips in which the central and guide eyes are punched or stamped out. There are two main types, single and double (duplex).knitted cord heald; noosed healdA heald consisting entirely of knitted textile cords, in which the central eye (or noose) is formed by looping.wire healdA heald formed from shaped wire. There are two main types:
(i) twin-wire healds, in which the central eye is formed by the separation (for the length of the eye) of the twin wires forming the heald;
(ii) inset-wire healds, in which a wire heald mail (known as an inset eye) is soldered in position between the separated twin wires to form the central eye.
Note.. Both types of wire heald have wire loops at each end so that they may be attached to the heald frame.heard frameA rectangular frame, which is used to hold wire healds or healds (see heald) made of flat metal strips in position. Loops or holes at each end of the healds enable them to be placed upon the bars across the frame and to slide on these bars.heald mail1. An oval metal stamping (usually of steel or brass) containing a central eye and two holes for fixing cords.
2. A wire heald mail (known as an inset eye). This is an oval metal stamping containing a central eye. The mail is fixed (i.e., inset) by solder in a formed loop in the centre of the wire heald.
