Model 729 Duplex Center/Surface Slitter Rewinder

The versatile 729 slitter is used extensively for a broad variety of pressure sensitives and other narrow-width slitting applications. This easy-to-operate, ergonomically-friendly machine provides a short web path from slit to rewind, simplifying cut-off and strand alignment at the core. The 729 offers center, center surface, and center minimum gap winding. Auto knife placement and other state-of-the-art technologies enable significant gains in productivity and finished roll quality.
