摘要： According to the present invention there is also provided an apparatus for estimating the fibre fineness of a known mass of fibres, the apparatus including: an image capturing device for capturing either i) all of the fibres selected for testing or ii) a fraction thereof, in one or more images; a computer capable of automatically determining the total length of fibre or fibres in the or each image; and a means for estimating the fibre fineness of the fibres using the total fibre length in the image(s).
摘要翻译： 根据本发明，还提供了一种用于估计已知质量纤维的纤维细度的设备，该设备包括：图像捕获设备，用于捕获i）选择用于测试的所有纤维或ii）其一部分， 在一个或多个图像中; 能够自动确定该图像或每幅图像中的纤维或纤维的总长度的计算机; 以及使用图像中的总纤维长度来估计纤维的纤维细度的装置。

摘要： A yarn (8) is spun by dividing (20) a travelling fibre assembly into a plurality of fibre sub-assemblies (9a, 9b), causing the sub-assemblies to traverse different paths and then recombining them (30), wherein the paths are sufficiently proximate for fibres to continuously transfer from one or more of the sub-assemblies and be drawn onto or into another or other sub-assemblies. Also disclosed is a method for forming a yarn comprising twisting a plurality of fibre sub-assemblies together at a convergence point (30) to form a fibre assembly being a yarn (9), and further including cyclically altering the relative twist propagation in and/or into the sub-assemblies upstream of the convergence point (30). Still further disclosed are alternative methods involving cyclic variation of paths traversed by the sub-assemblies, and cyclic alteration of the relative positions of the sub-assemblies. Apparatus is described for carrying out each method.
