Cartridge paper
Cartridge paper is the basis for drawing machine-compatible textile patterns when weaving . It contains a printed grid, similar to graph paper. The spacings between the lines, however, are larger, so that the textile pattern artist ( Dessinateur ) easy access to the respective yarn paths ( bonds can) in the box draw.
The finished pattern is called pattern cartridge or binding cartridge (hence the name cartridge paper ) in textile terminology : the longitudinal spaces correspond to the warp threads , the transverse spaces correspond to the weft threads . The punch cards or strips used to control the weaving machines were previously made using the sample cartridge.
For some years now, new weaving machines have been supplied with electronic shaft controls, the cartridges are drawn directly on the computer. Therefore cartridge paper has lost a lot of its importance today. However, there are still many old machines around, especially in the Third World, whose cartridges are still hand-drawn.
