Reading fluids circuit diagrams - hydraulic & pneumatic symbols

Reading hydraulic and pneumatic circuit diagrams and being able to make sense out of them is a valuable skill for mill personnel. The first article in this series presents fluid control elements.

Reading fluids circuit diagrams - pneumatic circuit examples

The previous articles in this series introduced fluids circuit elements and presented example hydraulic schematics. This article describes two example pneumatic schematic diagrams: winder lowering cradle safety pins and winder belted threader operation.

Calender safety - Handling calender rolls and parent rolls

Due to the weight and overall size of calender rolls, reel spools, and paper rolls, handling accidents can cause serious injury or death to personnel, and costly repairs to the roll, spool, or other equipment. However, handling accidents can be avoided if basic safety rules are followed.

Suction roll bearing failure - monitoring and lubrication tips

One of the most sensitive components of the roll, the internal bearing is difficult to maintain and unforgiving when it fails. Accelerometers are an effective means of monitoring and predicting suction roll bearing failure.

SymRoll troubleshooting - leakage, cover wear and vibration

For troublefree function of SymRolls, the following are troubleshooting and maintenance tips and procedures regarding oil leakage, hydraulic and pneumatic systems, roll cover wear, roll vibration and other roll change factors.

Measuring wound-in tension - WIT-WOT and gap test methods

Among the most important factors determining the quality of a finished paper roll is consistent roll structure. Wound-in tension is the most important component of roll structure. The WIT-WOT and Gap Test are methods of measuring wound-in tension.

Balancing rolls - balance and imbalance, isolating the problem

Unbalanced rolls hammer at the framework of the papermachine, leading to worn journals, bearings and covers. Balancing rolls lengthens component lifetimes.

Avoiding roll defects at the winder - causes and solutions

Most roll structural defects are caused by poor nip or tension. These tips will help operators avoid starring, soft starts, corrugations and crepe wrinkles.

Calender case study - CD caliper control & sheet breaks

A southern USA mill requested Valmet expert assistance, specifically a process and condition audit of their online single nip calender.
