摘要

The bushing comprises of upper chambers that are connected with one another and adjust themselves to system equilibrium, even if a guide jaw is far distant from the center, such that the radial strength is ascertained with the pressure in the upper chamber. The material guide bushing is movable individually and independently in radial direction, such that each jaw is individually attached to a material bar.
