Abstract
A method of and an apparatus for producing a blended yarn from cotton fibers and man-made or synthetic fibers. According to conventional methods the blending of cotton fibers and man-made fibers has been hitherto effected subsequent to a cotton combing process. In order to obtain an appropriate yarn quality, it is necessary to comb out the cotton and thereby separate the short fibers thereof. With the prior art method of bringing together or combining the blend constituents subsequent to the cotton combing process, there have been problems with regard to a homogeneous blending of cotton and man-made fibers. A great number of machines is thereby required and the corresponding constructional expenditure is high. Therefore, a method and an apparatus are suggested and according to which the two blend constituents, namely cotton fibers and man-made fibers, are already brought together or combined prior to the combing process. In this manner, there is obtained a homogeneous blend and a substantial reduction of the number of required machines is achieved.
