Abstract: The striper of the system is provided with yarnguide rods which are pivotable to a position conducive to delivery of yarn to the needle. The rod to be pivoted is selected by a selector which imposes a small movement on a slide member and this small movement causes the slide member to be moved by a first radial cam such that its movement causes pivoting of the rod. Independently of said pivoting, a closing lever and an opening lever respectively adapted to retain and cut the yarn or release it are always moved. The movement of said levers, is only effective when at least one yarnguide rod has pivoted. There is a striper for each cam section and all of them are controlled by a single selection box containing the selectors.
