STRETCHING UNIT

摘要

The invention relates to an improved stretching unit characterised, amongst other things by the following: the clip-chain unit (KK) is designed such that the forces which are exerted are decoupled and applied in a tilting-free and torque-free manner to the clip-chain unit (KK) in order to prevent an increase of the surface pressure between the clip-chain unit (KK) and the supporting rail (17).
