HEIMBACH 17
A typical Heimbach press felt
the term ‘money triangle’ almost completely from their vocabulary. And this is no exaggeration.
PPL: Can you explain this in more detail? FK: The best way I can explain is to go back more to than 2,200 years
ago, when Archimedes established the principle that was named after him. The fundamental understanding that he left to posterity tells us that when we get into a bathtub filled with water, the amount of water that we displace is equal to our body volume. Transferring this physical law to the operation of a press felt we could quickly establish that the felt has to be completely saturated – as quickly as possible!
PPL: Fastest possible water absorption equals the best possible dewatering? FK: Exactly. We have developed a module that consists of a specially- developed high-tech material. From now on ‘ff’ is the abbreviation that everybody who insists on ‘turbo start-ups’ needs to know.
PPL: And how do you assess the degree of saturation achieved? FK: Very positively. In tests we achieved complete saturation within an extremely short time. And of course, the felt still remains open- pored and does not become dense. The combination of these two characteristics ensures best performance over the entire life of the felt.
Heimbach’s ‘fast forward’ concept eliminates the ‘money triangle’
PPL: Is ‘fast forward’ suitable for any machine configuration? FK: Our special component can be used on almost all machine types. Moreover, all Heimbach base fabrics are compatible: This means that paper makers can achieve the best start-ups – no matter which base material is their first choice for the relevant machine or position. And we should certainly not forget this: Conventional felt designs without special start-up support need two to five days before they can
