the beginning of the stranding job of about 68 m per minute for the given lay length of 250 mm corresponding to the continuous decrease of material to be stranded on the spool and the resulting reduction in spool mass the number of cage revolutions can now be increased continuously as indicated schematically in fig2 so that the maximum number of revolutions of about 380 rpm permitted for the machine is reached after about 50 minutes this maximum number of revolutions is then used to remove the remainder of the material to be stranded from the spools so that stranding cage 1 can be operated at the maximum number of revolutions for about 15 minutes of the total operating period of about 80 minutes as a whole there thus results an average removal rate for the finish stranded material of about 82 m min for stranding cage 2 a lower number of cage revolutions results which corresponds to the greater length of the lay while with the described regulation stranding cage 1 is subjected to a centrifugal force of 60 000n it would have to absorb a maximum centrifugal force stress of 88 000 n for the same production output without the proposed regulation i e with operation at a constant number of cage revolutions this comparison of numbers itself already indicates that it is.
