Large I.D. Convolute Cores

A convolute core is a paper core made from a single web of fiber wound around and onto itself until the desired thickness is achieved. This method of manufacturing allows for 100% glue coverage unlike the spiral method which has seams with no fiber bonding. This method combined with a premium fiber and a high solids glue makes for a significantly stronger core. We have the latest technology available using this manufacturing method. Hundreds of flat crush tests have proven that a traditional spiral wound core can be replaced with a thinner convolute core while providing equivalent or higher strength. Reducing resources consumed, lowering costs, and providing a lighter weight core for the operators to lift are just a few of the benefits of this technology.

The primary market for large i.d. cores is the metal/steel industry.
