Boosting Efficiency in Corrugated Packaging: How the LJX™ Rotary Joint and Rigid Syphon System Enhance Runnability   Preheater and preconditioner rolls play a critical role in this industry, as they ensure precise heating of the linerboard and medium used to make corrugated board. Without consistent, even heating, quality issues and inefficiencies quickly arise. This is where the LJX™ Rotary Joint and Rigid Syphon System from Kadant comes in. Designed specifically for corrugators, this innovative system—distributed in Italy by Johnson-Fluiten—ensures optimal heat transfer, increases equipment durability, and minimizes downtime. Here’s a closer look at how the LJX system works and why it’s a top choice for corrugated packaging manufacturers looking to improve runnability.
