Prepress In Feed Line

Prepress In Feed Line

A large plywood operation was experiencing production bottlenecks on their “Prepress In Feed Line”.

Belt elongation, edge curl and buildup of wood fiber on the pulley side contributed to on going tracking issues. The customer was using a commodity 120 PVC style belt which had a limited life span. This presented additional maintenance and operational costs. Belterra personnel recommended a strong 3 ply polyurethane (TPU) belt that offered almost zero elongation after the initial run in. The TPU cover contributed to better wear and abrasion resistance, and the 3 ply carcass construction offered a stronger finger splice, and superior dimensional stability eliminating premature cupping. The TPU impregnated polyester fabric on the reverse side also gave the belt better wear and reduced the build up from mill debris that previously contributed to tracking issues. The lower coefficient of friction contributed to energy savings as it now cost less to drive the belt. Belterra’s recommendations provided better reliability and predictability in daily production allowing maintenance staff to focus on other issues.
