Such a method, however, requires one, but rather one provided with grooves, so that when the complex adjustment of the drive system and the counter-pressure cylinder and the drafting roller is rotated, the manufacturing costs of the moderate yarn distortions take place considerably, and that in worsted yarns. In addition, the "flamed" is flamed in an irregular manner.
Places represent weakened areas, as in the case of 35 Instead of grooves, grooves could be found in the rubber cylinder, pulling the slub yarn that is being provided, and both these grooves and those at the flamed places tear. mentioned grooves are according to any one of the objects of the invention, the above-mentioned known methods can be produced, for.
