Web Accumulators are available in either vertical or horizontal configuration. They can be free standing or assembled on a mounting plate for installation on another machine. They are available in capacities from 10 to 400 feet of web storage.

Large capacity Accumulators are designed with banks of moving carriages with each carriage fitted with two to five rollers, depending on Accumulator size. Accumulator rollers (fixed position rollers and carriage rollers) are normally aluminum with a hard anodized finish. The rollers can be straight, concave or convex, depending on the web and how it tracks through the Accumulator.

The carriages which carry the moveable rollers ride on low friction linear ball bushing shafting. Whether the Accumulator has one bank of moveable rollers (one carriage) or multiple banks (multiple carriages), tension on each carriage and the web in that bank is adjusted by means of a pressure regulator which controls one or more air cylinders acting on that carriage.
