The Golden State: Where & How to Live, Secure, Visit, Enjoy and Thrive in California
Carpets And Rugs
The mechanism which selects the proper color is known as a "Jacquard attachment". Tts operation is controlled by a perforated record which resembles very much the record that is used for player pianos.
The carpet salesman employs a limited number of technical terms which can be easily explained by reference to the Brussels loom shown in Figure 24, Plate 1. For instance, a Brussels or a Wilton carpel is said to have B certain number of frames. By frames is meant the number of worsted pile threads which pass through each dent of the reed. In this case a three-frame set-up is shown. Ordinarily, a carpel has as many frames as colors but not always.
Sometimes a pattern is worked out in such a way that the color set-up can be changed in certain portions by substituting one color for another. For instance, in Figure 33, Plate II, a sample is shown where bright green has been substituted for blue at regular intervals across the carpet. This substitution of color is called "planting". Tt can be detected by following a color lengthwise of the rug and counting the number of colors that appear in that line.
Referring to Figure 24, Plate I, which is a three frame set-up, if for every sixth dent green is substituted for red, we would have a carpet with lour colors in it and yet the number of frames would still be three. The number of frames is a measure of the amount of worsted in the carpet.
Wires and Pitch
The loops of Brussels carpet are formed over wires and the number of wires per inch is a measure of the number of loops. Therefore, a ninewire carpet is one that has nine loops per inch of length.
