Principle of frictionless load and other features
The crucial feature of the HP family is frictionless direct loading of the top rollers using plate springs and the fact that the spring is supported in the guide rail without play. The plate spring both serves as the guiding element and prevents lateral forces from acting on the top roller position.
The surface of the HP Top Weighting Arm is particularly resistant to aggressive substances and can withstand even the most demanding requirements of industrial applications. A corrosion test performed by an independent laboratory showed that the surface has three times more resistance than had previously been achieved.
