Registration Control Systems using Amadeus® Automatic Register Controllers
Amadeus Automatic Register Controllers, new from Andantex, combined with Differential Phase-Shifters to provide a complete electromechanical register control system.  These system are designed for use on printing and converting machines requiring precise registration between the tool and product.

• Automatically corrects the registration error resulting from product transfer for sheets
• Automatically corrects for slipping or varying product lengths for continuous products (web)

Differential Phase-Shifters
This complete line of Differential Phase Shifters allow precise adjustment of the angular position of the output shaft, relative to the input shaft, while the machine is at rest or in motion. They are available in 6 sizes and 5 model types, with ratios from 1:1 to 3:1. The model types are in-line DLO & DLO.D, right-angle DR, and right-angle clutching or reversing DRD & DRI.  These Differential Phase Shifters are especially effective in phase shifting and register control applications where space is limited and versatility in design is essential. Typical applications include: In-line Web Finishing Equipment, Printing Presses, Labeling Machines, Plastic or Film Web Machinery, Packaging Machines, Textile Machinery, Paper Converting Machinery, Timing or Cutoff Knives.

• Register Control Between Print Units

• Register Control of Die-Cutting Station

• Speed & Position Control for Finishing a Pre-Printed Web

• Phase Plate Cylinder Independent of Impression Cylinder

• Speed, Position and Tension Control of Web on Infeed and Outfeed Cylinders

Narrow-Band Draw Control Differentials
The DLA line of differential transmissions provide a narrow band of variable output speed (+/- 0.50 to 10% of input speed) while at the same time insuring that any speed set within this band will hold nearly as well as fixed gearing (i.e. less than +/- 0.005% deviation).  Therefore, the DLA provides the accurate speed setting and precise speed holding required to insure web or strip tension control.

•  Precise Speed Control of Draw-Roll

Cycloidal Differentials
The differential series 2SRD and DLS consist of a nearly zero-backlash cycloidal gear train.  They provide dynamic motion profiles including rapid acceleration rates, high speed and precise repeatability.  Therefore 2SRD and DLS differential drive systems combine the reliability of mechanics with the precision of servo-electronics.  The differentials can be used for cyclic synchronization of two speeds, creation of a relative speed while running, and dynamic register control.  Applications are typically found in the Converting, Printing and Packaging industries.

• Cyclic Synchronization of Impression Cylinder

• Dynamic Register Control of Cylinder

Z-Series Spiral-Bevel Gearboxes
The new Z-Series Precision Spiral-Bevel Gearbox range was streamlined from the R-Series to increase the number of common parts, while lowering costs and reducing lead times.  Available in 7 sizes & 6 model types, they feature high-quality, case-hardened & lapped alloy steel spiral-bevel gears, cut by the Klingelnberg method.  This high quality level insures low noise, backlash, and transmission error. These versatile units can be used as both reducers and increasers. Two shaft, three shaft, forward, neutral, and reverse models are available with horsepower ratings from 2 hp to 540 hp. Solid through-shafts and hollow bores are also available.

• Electronic Line Shafting

• High-Speed Continuous Duty Drivetrain

Planetary Epicyclic Differentials
The Type SA planetary epicyclic drive is the latest generation of Rotomission® technology. This compact, versatile differential consists of three elements which are mechanically connected by the sun and planet gears.  Combining the motion of the three elements solves many electro-mechanical drive problems.  Applications include reducer/increaser, two or more speeds, phase-shifting, precise speed adjustment, creation of relative speed while running, cyclic synchronization of two speeds, timing movements, and balance speed & torque.

• Phase-Shifting of Two Connected Driven Elements

• Register Control on Preprinted Web

• Register Control of Two Color Flexographic Printing Press

• Web Tension Control of Infeed Station of Printing Press

BD Series Single-Position Jaw Clutches
These clutches are used wherever different sections of a machine need to be first disengaged from the drive train and then re-engaged while maintaining the same phase or angular relationship which existed prior to disengagement. They are often used in a line-shaft, between printing units on an offset-printing press, and to disconnect certain units on a finishing line.

• Engage/Disengage Print Units or Machine Sections

AnglGear Right-Angle Drives
This line of Coniflex straight-bevel gearboxes has proven its performance for over 40 years. Developed to provide manual or power transmission of rotary motion in a compact, standardized right-angle unit. Each AnglGear is manufactured at our factory in Wanamassa, NJ, and all components are manufactured in the USA. The units are available in 5 sizes (in both inch & metric dimensions), with ratios 1:1 and 2:1, and powers up to 20 hp.

• Manual adjustment of cylinders
