Unique internally-fed design
Unist’s roller systems feature a unique internally-fed roller design and provide an environmentally-friendly solution for applying lubricants to coil or sheet stock.
The Unist product line is built around the concept of applying lubricant in a precise manner, which results in fluid usage reduction, the elimination of fluid mess, and increased production rates.
The design of the internally supplied rollers is the key to applying fluid. Inside each of the rollers there is a dispenser tube with several small holes spaced along its length. Every time fluid is injected into the
dispenser tubes from the fluid controller, it is dispensed evenly across the inside of the rollers through these holes. The lubricant is then transferred to the stock through a durable polyester felt roller cover that applies the lubricant smoothly and evenly across both the top and bottom of the stock. As the system continues to cycle, additional lubricant is injected to replenish the lubricant applied to the stock.
The Apex™ cupping press coil lubrication system
Designed specifically for coil lubrication in the can making industry, the Apex™ cupping press coil lubrication system gives can makers precise control over the application of their cupping lubricants. The unique internally-fed roller design of the Uni-Roller®, combined with the Apex™ controller has proven itself capable of applying lubricants in quantities as low as 15-20 mg/ft2 [161-215 mg/m2]. This level of control, combined with high reliability, provides years of exceptional performance with minimal maintenance.
Always accurate
The Apex™ controller takes coil stock lubrication to new levels of precision and convenience with features not available in any other lubrication system. The Apex™ is an upgrade to Unist’s proven SPR-2000™ technology and utilizes an electronically-controlled, positive-displacement pump to provide precise and repeatable volumes of lubricant to the coil. The positive-displacement pump is not impacted by changes in fluid viscosity, which allows consistent application of lubricant regardless of the ambient temperature. PLC-based controls allow for easy setup, troubleshooting, and monitoring of the lubrication system both at the press and remotely using Ethernet connectivity.
