New LRH automatic transfer rewind from Martin Automatic

Martin Automatic has introduced the LRH automatic transfer rewind — a nonstop roll changer ideal for mid-web printing, laminating and converting processes. The LRH provides continuous, roll-to-roll productivity for a wide range of applications and materials, from film to paper and paperboard.

‘The LRH delivers maximum productivity with minimum effort. Operators need only to load the cores and the LRH winds, automatically changes and unloads full rolls,’ said the company in a statement.

The cantilevered spindle design of the LRH eliminates the need to handle heavy coreshafts. A rigid outboard support system negates spindle deflection. Unlike conventional turret winders, the LRH rewind spindles traverse horizontally — minimizing roll travel and eliminating tension upsets and web shifting associated with turret rotation.

‘The LRH builds on the enormous success of two of our winding machines-the LRD and the RMAP and provides additional benefits. The LRH can handle a larger roll diameter than the LRD. Since roll change is on a horizontal plane, the operator doesn’t have to move heavy shafts. The LRH unloads and de-shafts itself,’ reported David Wright, vice president sales/marketing. The first LRH has already been sold and will be running paper and light board weight stock.

The LRH is offered in standard widths to 32 inches (813 mm) and standard diameters to 72 inches (1830 mm). Wider widths and specially-engineered features are available.
