LBZ rewinders are designed to ensure high winding quality, process control, and maximum versatility in the processing of technical papers and laminated materials.
The machine shown has been developed for processing a wide range of products, from traditional kraft papers to complex materials laminated with polymers, aluminum, raffia, and other substrates intended for the industrial, food, and technical packaging sectors.
Thanks to fully customized design, each system is configured according to the customer’s specific production requirements, ensuring high performance, operational reliability, and consistent quality of the finished product.
The heart of the machine consists of an advanced active tension control system, managed through load cells and automatic adjustment systems that continuously monitor winding conditions.
A reel relief unit compensates in real time for variations caused by the increasing weight of the roll, allowing constant contact pressure to be maintained and producing compact, uniform reels that are easy to use in subsequent processing stages.
This solution is particularly effective in handling large diameters and materials with different mechanical behaviors.
The rewinder can be equipped with automatic motorized knife cutting systems, allowing automatic positioning of the cutting units and fast format change management.
The high positioning accuracy ensures process repeatability, reduced downtime, and greater production efficiency.
Particular attention has been paid to operator ergonomics and safety.
The assisted paper threading system facilitates winding operations and reduces the time required for production changes, while the reverse function allows any defects to be corrected directly on the machine, avoiding unnecessary waste and improving process continuity.
The supervision interface allows constant monitoring of all operating parameters and intuitive management of production recipes.
Main features
Every LBZ rewinder is born from a project developed together with the customer, with the aim of achieving the best balance between productivity, product quality, and ease of use.
From traditional applications to more complex processes, we manufacture customized systems designed to meet the specific needs of every converting process.
LBZ rewinder with supporting rollers are designed for processing technical papers, kraft papers, coated papers, special papers, and cardboard, ensuring high winding quality even at maximum production speeds.
Thanks to the winding principle on supporting rollers, the weight of the reel is supported directly by the machine, allowing the production of large-diameter finished reels with excellent compactness, perfect edge formation, and uniform tension distribution across the entire material width.
Each system is developed according to the customer’s specific production requirements, with customized configurations for working width, reel diameter, cutting systems, and automation levels.
The machine architecture allows stable winding conditions to be maintained throughout the entire production cycle.
The load and pressure control systems on the supporting rollers, integrated with dedicated measuring cells, make it possible to optimize reel density according to the type of paper, grammage, and the characteristics required by the subsequent process.
The result is a compact, stable reel, ready for further processing or shipment.
LBZ rewinders can be equipped with fully customized cutting units, fitted with high-precision motorized knives.
Automatic knife positioning drastically reduces format changeover times and ensures repeatability and precision, even in production processes with frequent dimensional variations.
The configuration can be adapted to the number of reels required and to the specific production needs of the paper mill.
Automation and productivity
To maximize plant efficiency, the machines can integrate:
The high level of automation reduces downtime and increases operational safety.
LBZ rewinders are built with highly rigid welded steel structures and selected industrial components to ensure reliability in continuous operation.
The structure is designed to absorb the stresses generated by large-size reels and operating speeds of up to 2,000 m/min, maintaining precision and stability over time.
