With Tidland’s Equalizer Model D3 Differential Air Shaft, operators can run a variety of different roll widths with adjustable pressure all along the length at the same time. The Equalizer D3 is guaranteed to provide core positioning with adjustable air pressure without spacers or core stop setup. It’s designed for duplex center or surface winders for multiple roll tension equalization. When not covered by the core, tension elements mechanically lock in place to secure core position through the entire run. The D3 requires no tools for core stops, no core stop positioning. Use these air shafts and say “No” to tools, spacers, core shifts and waiting for core position setup.
