The warp threads that form the braid are wound around weighted bobbins called tama (lit. ' egg '). [1] Tama were once made of clay [when?], but now are most commonly wood filled with lead. The weight of the tama maintains even tension on the warp threads, and is balanced by a bag of counterweights called omori [1] that is attached to the base ...
Lucet may unravel if cut, but is easily fixed with a small knot. Unlike other braiding techniques such as kumihimo, finger-loop braiding or plaiting, where the threads are of a finite length, lucetted (or knitted) [a] braids can be created without pre-measuring threads and so it is a technique suited for very long cords.
This shield is usually covered by an outermost layer of the cable. Common types of cable shielding can most broadly be categorized as foil type (often utilizing a metallised film), contraspiralling wire strands (braided or unbraided) or both. [2] A longitudinal wire may be necessary with dielectric spiral foils to short out each turn. [1]
When the pattern is to be removed from the sand mold, there is a possibility that any leading edges may break off, or get damaged in the process. To avoid this, a taper is provided on the pattern, so as to facilitate easy removal of the pattern from the mold, and hence reduce damage to edges. The taper angle provided is called the Draft angle ...
1925 braiding machine in action The smallest braiding machine consists of two horn gears and three bobbins. This produces a flat, 3-strand braid. A braiding machine is a device that interlaces three or more strands of yarn or wire to create a variety of materials, including rope, reinforced hose, covered power cords, and some types of lace.
Bobbin lace may be made with coarse or fine threads. Traditionally it was made with linen, silk, wool, or, later, cotton threads, or with precious metals. Bess of Hardwick bought red silk, gold, and silver thread for making "bone lace" in 1549, the earliest English reference to this kind of work. [13]
The patterns are designed to look good, but also to distribute light and wind in a calming and beautiful way. [ 5 ] Traditionally it is made with hand-tools only, but in the western society they have made new techniques to make these kinds of patterns, it involves a table saw, a sharp chisel, and some guides made by yourself, some can be made ...
Another kind of scoubidou thread is supple, round, and hollow plasticized PVC tubes usually about 80 centimetres in length. They are sold in various colors, sizes, and types, and are used to make items by binding them together with knots. On account of their elasticity and hollow cross-section—which enables them to collapse and deform when ...
