Abstract
The invention relates to a method for feeding yarns of different colors to a conventional knitting machine for producing striped fabrics (circle-striped fabrics). The first step of the method according to the invention consists in selecting and presenting a predetermined length of a yarn of a desired color in accordance with the striped pattern to be produced. The so selected and presented yarn lengths are subsequently joined to form a continuous yarn. In a third step, the continuous yarn formed of said joined yarn lengths is intermittently formed into an intermediate store, from which the yarn is positively fed to the knitting machine at a constant speed in synchronism with the operating speed of the knitting machine. In this fourth step of the method, the continuous yarn is fed to the associated knitting system of the machine. Joining of the individual yarn lengths to form the continuous yarn is carried out in synchronism with the operating cycles of the knitting machine, so that the intermediate yarn store is formed at a rate corresponding to the yarn consumption of the knitting machine for each revolution thereof. This permits the splices between the individual yarn lengths to …
