Overview:

The Martin LRH Automatic Transfer Rewind is 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 winds, automatically changes and automatically unloads full rolls. The only operator task is to load cores.

The cantilevered spindle design of the LRH eliminates the need to handle heavy coreshafts, and a rigid outboard support system negates spindle deflection. Unlike conventional turret winders, the rewind spindles of the LRH traverse horizontally. This linear design minimizes roll travel as well as the tension upsets and web shifting typically associated with turret rotation.

When the specified footage has been rewound, or upon a signal from the process or the operator, the web is transferred from the full roll to the empty core — without stopping or slowing the process. The spindle is deflated and retracted from the finished roll, which is lowered to floor level for delivery. The running roll traverses to the winding position, and the empty spindle returns to the transfer position for core loading.

The LRH is enclosed for safety, while enabling the operator to view all functions of the rewind.

Engineered for versatility, the Martin LRH will accommodate design features to meet specific material and process requirements. Available options include integrated slitting and web guiding systems.
