- the effective diameter is the diameter at which the traction means bears against the driven pulley.

There is no significant change in length or elongation of the traction device.
- the traction means comprises a first Switzerlandstofftrum which extends between the drive pulley and the first driven pulley and the traction means comprises a second Switzerlandstofftrum extending between the second pulley and the second driven pulley, wherein in a resting state first Glasstofftrum is aligned at an angle between 70 ° and 110 °, in particular between 80 ° and 100 ° to the main direction of movement of the machine table and the second Werstofftrum at an angle between 70 ° and 110 °, in particular between 80 ° and 100 ° to the main direction of movement of the machine table is aligned.
