PAPER MACHINE

Tavole Piane DJM De Iuliis 1
The forming section of the paper machine directly influences the physical and mechanical properties and the quality of the paper. Based on its experience, De Iuliis carefully determines the ideal configuration based on the type of paper produced, ensuring a perfect formation process. From single-layer to four-layer machines, De Iuliis is capable of designing and manufacturing any type of forming section. All the structures are designed in cantilever, ensuring fast and easy cloth changes, and are made of stainless steel. Particular attention is given to preventing vibrations to reach maximum speed without any structural issues.
DJM is capable of developing and manufacturing solutions perfectly integrated into the paper mill’s needs, ranging from improvements and extensions of the forming section to the design of completely new and customized “turnkey” solutions.

Specifications

The main components that make up the forming section designed and built by DJM include:
• Cantilever frames
• Drive and breast roll cylinders with lowering systems
• Stainless steel suction rolls
• Guide rolls
• Low and high vacuum boxes
• Stainless steel doctors
• Automatic regulators
• Mechanical and pneumatic wire stretchers
• High and low-pressure oscillating showers
• Dandy rolls

DJM Former

De Iuliis Top Former is positioned on the forming wire. It is an additional dewatering unit on the top of the paper used to guarantee an homogeneous drainage of the sheet. The main advantage of De Iuliis Top former installation (even on existing wire table) consists of increasing paper drainage from the top and therefore reducing the length of the forming table. From slow speed machine for cardboard or graphic paper production to high speed ones for packaging paper, the Top Former can guarantee enormous benefits for the paper formation process, symmetrizing the drainage between the two paper faces, improving its final characteristics and increasing the dryness after the formation area.

Mould Cylinders and Mini Forming Fabrics

In addition to Fourdrinier-based production systems, DJM is capable of supplying forming systems with formers/mould roll (with or without a vacuum box) or mini forming fabrics for the production of heavy boards and specialty papers.
The modular mini-forming fabrics are ideal for the production of multi-layer boards up to 1200 g/m², and allows the reduction mould rolls required while increasing machine speed.


Main advantages include:
• Low operating costs
• Low vacuum requirements
• High productivity (30-190 g/m² per fabric and up to 1.2 t/h/m² per fabric)
• Increased productivity and speed (up to 450 m/min)
• Excellent layer adhesion
• Reduced installed power
