2.3.5 Rotary speed of the tube
The rate of tube turns is mostly determined by the cycle time. See previous chapter „Cycle time
and duration of weld seam detection".
However, it may happen that a very short cycle time requires a very high tube rotation speed N.
This can lead to system-related limitations. To check use the formula below:
750
A
however > 5 rpm and < 300 rpm
There are no restrictions if the rate of tube turns N is within the limits.
2.3.6 Speed
At friction roller drive the speed of the surface / of the periphery is specified.
Whether system related limitations are observed can be checked using the following formula:
There are no restrictions if the velocity V is within the limits.
