Leaf Shafts
Eliminates thin wall core deformation for superior roll quality and reduced vibration
360 degree radial and full length expansion for winding single or multiple rolls, with or without cores, improving product quality
Fixed leaf design provides improved roll centering and clearance for loading
Leaf Shafts Overview
Designed for a wide range of converting applications, these shafts are best for the elimination of thin wall core deformation. The 360º radial expanding grip along the entire leaf face delivers more winding surface and allows for the winding of single or multiple rolls, with or without cores.
With smooth, polished external leaves, these shafts are particularly suited for delicate materials. Leaf Shafts are built tough, with bodies constructed of standard steel, alloy steel or aluminum and internal tubes made of durable, hard-wearing rubber. Simple modular construction and standardized components mean quick off-the-shelf spares service and easy in-plant maintenance when necessary.
