A cotton type machine usually requires for the forma

withdrawn from the yarn spool Y. During this time
period the following operations take place in the described

It was found through actual practice that it is advisable
to operate one cam at a time, so that the cams will be
actuated consecutively. This eliminates excessive tension

knitting elements of the machine. Through the use of a
