The Heddles are for lifting the threads of the warp so that the shuttle may be passed through.
In the case of small patterns the movement of the heddles is controlled by "cams" which move up the heddles by means of a frame called a harness; in larger patterns the heddles are controlled by harness cords attached to a Jacquard machine.
The warp threads are separated by the heddles into two or more groups, each controlled and automatically drawn up and down by the motion of the heddles.
But to work an upright warp-weighted loom with heddles is attended with great practical inconvenience, and this difficulty has, no doubt, been one of the chief causes of the complete discardance of this class of loom.
Porter has sent me photograph of another sort of loom in which weights are used as counter balances to keep the heddles raised.
Such a quantity of heddles with its complicated harness as Mr. Lee considers necessary is quite out of the question with a loom so undeveloped as not to be provided with a reed.
The supports on which the heddles rest when the "pick" is made [i.
But theheddles are all extremely primitive, and in my experience do not exceed four in number where there is no reed.
In brocaded, figured or tapestry weaving, leashes or loops called heddles were hung from above and lifted whatever part of the warp they were attached to.
For example, three threads out of ten in the warp could be lifted by one group of heddles with one motion of the treadle, the heddles being grouped or "harnessed" to make this possible.
When these threads are closed by the operation of the heddles to form the inner texture, the first tendency will be to move in the direction 1 b, 2 b, &c.
In the Lyons imitation of this style, the leaves of the heddles lift the yarns of the warp, the needles embroider as in lappett weaving, and the flower is united to the warp by the weft thrown across the piece.
The heddles are connected and work with the treddles B B, by means of cords, as shown in the figure.

These plans are horizontal sections of a loom, the heddles being represented across the paper at a, and the treddles under them, and crossing them at right angles, at b.
Plain Venetian carpets, as used for stairs and passages, are woven in simple looms, provided merely with the common heddles and reed.
In all the plans shown by these figures, excepting one which shall be noticed, a connexion must be formed, by cording, between every leaf of heddles and every treddle; for all the leaves must either rise or sink.
In both these the warp is inserted into the heddles the same way.
In the simple low warp hand-loom, the warp being in two sets, the alternate threads are lifted by the heddles alternately.
These heddles are connected with treadles worked by the feet of the weaver, who, with his hand, passes his shuttle with the woof backwards and forwards through the interstices thus left, and weaves the plain cloth.
This done, the position of the heddles is reversed, so that A is now lowered and B raised, thus binding the warp thread in place and forming another shed for the next warp thread; and thus the process continues.
The intervening loops and threads are attached to another frame or "heddle," and the two heddles by being worked, one up and the other down, separate the warp threads to form the shed.
The drawing of warp threads into the eyes of the heddles and through the reed of a loom requires great skill, and prior to 1880 was performed by hand at great expense.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "heddles" in a variety of sentences. We hope that you will now be able to make sentences using this word.
