Instructions for safe removal of calender stack rolls and drives

Machine calender rolls are typically removed using a house crane and slings. This article presents typical stack roll removal instructions and safety. Always refer to original equipment supplier documentation and mill procedures for the actual procedures.

Two front splicing methods and safety precautions with each

Two efficient winder front splicing methods are presented. Front splicing is more dangerous than rear splicing, i.e. nip hazards. One person should supervise.

Safety when lifting, operating and servicing felt rolls

Off-machine coater splicing is affected by several parameters

Splicing efficiency on coaters averages about 98%. Variables that affect the splicing process include primary roll speed match, paster roll speed match, paster roll gap, paster roll pressure, paper caliper/hardness profiles, splice tape pattern and tail length.

Understanding coater blade angle vs. loading tube pressure

For a given blade tip bevel, when load tube pressure is increased, the blade angle will decrease, resulting in the blade running on its heel for a while. This, along with the additional bending pressure at the blade tip, will reduce coat weight. It is important to understand the interaction between blade angle, blade tip angle and loading tube pressure.

Common fluids valves explained: Pressure reducing valve

Pressure reducing valves are used to create and hold a pressure setpoint in a downstream hydraulic branch. Valmet uses sandwich style valves because they are easy to fit in a stacked hydraulic valve block circuit.
