Abstract
A friction spinning machine comprising a perforated roller (6) and an imperforate roller (19) is so designed that high-quality yarn can be produced in various sizes and with adequate strengths at a relatively high rate of output. The adjustment parameters necessary to solve this problem are specified in detail, more particulary those determining the position, orientation and shape of the fibre feed duct (5).
