Bulk generation is on the mind of every tissue maker. Light Dry Crepe (LDC) is in the constant pursuit of improved bulk in the finished sheet.

"Dryer bars", also called "Spoiler bars" consist of a number of equally-spaced rows of steel bars that are held against the inside surface of the dryer shell.

Infrared (IR) thermography has become an essential tool in many Predictive Maintenance (PdM) Programs.

Mobile maintenance, 3D modelling, robotic lifts, machine vision, digital twins and what else.

British master papermaker, James Cropper, based near Kendal in the English Lake District, has invested in the web-hosted Machine Sentry® system to monitor and provide 'watchkeeping' data and fault diagnosis to support the on-site engineering team in planning an effective programme of equipment maintenance and replacement.

A direct steam injection heater uses 100% of its steam energy to heat water-based fluids.

The easiest way to dispose of condensate is to dump it down the drain. This is also the worst way to dispose of condensate.

In 2017, we set forth a vision to establish our pulp business as a growth driver for the company.

Vibration and wear in a multi-roll steel calender stack can lead to a phenomenon known as calender barring.

Continuing to enhance our Royale tissue product with new technology.

Yes, there is a difference and the difference can be quite significant. OEM (original equipment manufacturer) parts are designed specifically for that equipment.

Determining the correct doctor blade for an application requires answering a number of questions to ensure the right blade is chosen to produce the needed outcomes of the application.

In Part 1, two major sources of chatter causing vibration were highlighted: chemistry and doctors. In this post, we examine the impact excessive moisture can have on Yankee chatter.

Chatter on a Yankee is a result of multiple process and mechanical issues in the manufacturing of tissue that cause the doctor blade to skip or flex, and eventually bounce on the dryer surface digging into the metal and leaving chatter marks.

Challenge
A high-volume, high-speed single facer at a corrugated packaging plant located in California (USA) was having issues with poorly bonded board after starting up from a stoppage of any duration. The poor bond between the corrugated medium and liner was resulting in excess waste and lost production.

Creping blade suppliers should be able to provide tissue makers with a number of essential services and products.

PT rotary joint with integral protective shield keeps debris out of the sealing area and enhances safety around the rotary joint.

With energy consumption being of prime importance in keeping operating costs optimized there are a number of design considerations at the PM Dryer Hood which can have a significant impact on energy savings.

If you have water or fluid in your process system, it's likely you have solids build-up. These solids can cause difficulty in the production process.

For the process industries, one of the most critical and often overlooked assets is the automated control valve.
