D2 Differential Air Shaft

D2 Differential Air Shaft
For optimum control over roll quality and setup time
Tidland’s Model D2 Differential Air Shaft is designed for duplex center or surface winders, whether variable speed control or not. It is simple
to set up, easy on the cores and reacts well to multiple roll tension equalization. Quick-to-position tooless locked core stops provide optimum
control over roll quality and setup time.
Bottom line is, operators can increase productivity by running varying roll sizes at one time with the help of Tidland’s most affordable
differential air shaft.
Key Features
Quick and easy setup – Lock cores laterally with inflation tool
Versatile - Slit widths down to 25.4 mm (1 inch) wide
Reduced dust – Core friendly tension elements and core stops reduce wear on the core
Operator-positioned toolless core stops lock independently to prevent axial slip of cores and reduce setup time on repeated roll sets
2.3 mm (3/32 inch) wide tension segments provide pneumatic, frictional torque control against core ID for equalized tenion roll to roll
Pressure control valve provides regulation of machine air pressure
Automatic inflation/deflation and core stop activation allow remote operation
