Tissue Makers Jazz Up New Orleans

Last week tissue makers and converters from around the globe visited Tissue World in New Orleans, Louisiana. The exhibition and conference, themed Beyond Sustainability – Leading a Culture of Innovation & Responsible Production, offered a variety of opportunities for learning. Speakers covered ways to improve Yankee efficiency and runnability, and technological innovation and energy efficiency in tissue production.

Causes of Yankee Chatter (Part 1 of 2)

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. Chatter issues have plagued tissue makers for decades, causing substantial losses in production and profitability. When chatter becomes an operational problem and there is need to grind the Yankee to eliminate the defect, expect up to a week of downtime. Surface refinishing is an activity that is costly in labor, lost production, and the grinding service.

Are You A Nonwovens Manufacturer?

While many trade associations continue to revise their formal definition of nonwoven materials and fabrics, one thing is for sure: the definitions exclude papermaking. But why? Sure there is market pressure surrounding papermaking that seems to have no effect on the nonwovens industry. But if nonwovens producers distance themselves too far, they risk missing out on the process improving efficiencies developed for and perfected in the pulp and paper industry.

Steam Hammer in Continuous Casting of Steel

Continuous casting of steel is the process where molten steel is solidified into a semi-finished billet, bloom, or slab for subsequent rolling in the finishing mills. Effective water cooling of continuous casting rolls is critical. Any drop in water pressure, even from a leaking hose, can result in reduced water flow causing water to remain in the rolls longer than recommended.
