Présentation de l'éditeur
The process of weaving-, either on the hand loom or power loom, depends upon the same principles, with practically the same operations. The principal parts of the loom, such as the lay, which is used to beat up the filling-; thereed, by means of which the warp threads are kept in their proper position ;the heddles, used for the separation of the warp threads; the harnesses, by which the weaving of the design is controlled ;the leese rods, used to keep the warp threads parallel to each other, all vary but little in either loom. The shuttles are similar, and the warp and cloth beams serve the same purpose. The quality of work differs but little, although the production of the power loom exceeds that of the hand loom. This is due to the fact that the driving of a loom by power allows more picks to be introduced into a fabric in a given time than is possible by the hand and foot power of a hand loom. Weavingwas practiced by the Egyptians, although little is known of their looms or the manner in which they prepared yarn for the loom. The discovery of a few wall paintings at Thebes, among which were representations of the Egyptian methods of weaving and spinning, gives us our first knowledge of ancient looms. One method was to weave the fabric in a horizontal position, in fact, on the ground, the weaver sitting on the woven fabric. Vertical looms were also used, the weaver throwing the filling through the shed by means of a rod. On the end of this rod was a hook, to which the filling was attached. Two weavers were frequently employed, sitting at either side of the loom, passing the rod back and forth through the shed. The Greeks and Romans used vertical looms similar to the Egyptian. The cloth was woven upwards, the warp being suspended from the top beam of the loom, and the lower ends tied in separate portions and weighted to keep the threads in tension. The fill
