Definitions
- US Patent 5,830,516 One of the methods and arrangements used in the manufacture of such slotted-core cables is disclosed in US Patent 5,830,516.
- the described solution is based on the use of a calibration device, which causes problems with regard to line speed, for example.
- a further problem in this solution is that it can only be used for manufacturing helical grooved elements, SZ grooved elements cannot be manufactured using the solution of US Patent 5,830,516.
- Figure 2 is a schematic view of the arrangement of the invention
- Figure 3 is a longitudinal view of the elongated grooved element manufactured using the arrangement of the invention.
