The ContiRoll continuous press has long stood as one of the Siempelkamp’s most groundbreaking innovations. Their R&D team has continually reimagined and enhanced this concept with visionary expertise. Through ongoing research and development, they ensure that their customers receive exactly the products their markets demand — from furniture panels and interior fitting boards to flooring laminates, ultra-thin boards, lightweight solutions, and boards crafted from fast-growing raw materials.
The ContiRoll represents nearly 40 years of continuous innovation in Siempelkamp press technology. With over 360 presses sold and operating worldwide, the ContiRoll is now in its ninth generation. Key advancements over previous models include an extended flexible press infeed, an innovative heating system, upgraded hydraulics, and higher press speeds, delivering unmatched performance and flexibility.
Hydraulics concept: Dimensionally consistent, high-quality products
The hydraulics of the ContiRoll Generation 9 are configured precisely for the production spectrum of the plant operators. For example, the hydraulics can be configured to the special requirements of thin board/ultra-thin board or lightweight board production, as needed.
Thickness control in conjunction with the hydraulic system plays a special role. Even if deviating product quality has been detected, under some circumstances, several square meters of scrap board will still be produced, since a faulty product thickness must only be compensated via the thickness feedback.
According the Siempelkamp professionals, “Consequently, we have perfected the thickness measuring process of the ContiRoll Generation 9 to ensure at all times the certainty of a high-quality product, even at the highest production capacity.”
“It was possible to implement this solution approach for a thickness measuring process, which is independent of all influence factors of the machine, through a separate construction. A statically stable, autonomous measurement frame serves as a solid reference dimension reference point – uncoupled from all thermal and static influence factors.”
ContiRoll Ecodrive for more energy-efficiency
The Ecodrive, as well, has already proven itself for the 9th generation of the ContiRoll. This is a synchronous motor technology that offers improved stability of rotational speed, works with significantly greater energy-efficiency than earlier concepts and it is extremely maintenance-friendly. The ContiRoll-Ecodrive system offers potential energy-savings of at least 7% in full-load operation and up to 14% in partial-load operation – and it does so with optimum efficiency. Constant high torque over the entire production speed range, up to 2,500 mm/s, is an important system characteristic.
ContiRoll® Generation 9 NEO – A new era begins!
The latest version of the continuous press ContiRoll, under the name ContiRoll Generation 9i, introduces optimizations for plant operators in three essential aspects: reliability, performance, and the accessibility of the press. At LIGNA 2023 they will present the latest version of Generation 9 under the name ContiRoll Generation 9i: “i” standing for “intelligent” and “innovative”. The proven and mature design of our press has received updates that redefine the triad of reliability, performance, and accessibility to the press – central to plant operators.
Reliability
A redesigned lubrication system for the roller rods provides the plant operator with even more reliable and precise lubrication of the roller rods across the entire width of the plant. This ensures that the correct amount of lubrication is applied. The new lubrication system can also be retrofitted. Further optimizations are focused on the steel belt control: The proven design of the ContiRoll ensures optimum steel belt tracking, resulting in a small necessary adjusting range of the steel belt control. This leads to less stress and prevents deformation on the steel belt. In general, the optimization aims at a long service life of the steel belts, as well as excellent control of the steel belt by the operating personnel.
Performance
In the “Performance” area, a symmetrical hotplaten joint comes into play, which ensures uniform rollover behavior and thus enables consistently high production output. Optimizations have also been made to the second heating platen. These are aimed at high production output, faster heating of the press, and precise control of the hotplaten temperature via the heating circuits of the ContiRoll® Generation 9i. The ever-longer presses will also be able to perform reliably and efficiently in the future thanks to targeted adjustments to the chain tensioner.
A central innovation targeting the performance of the press comes into play with the adaptive forming system developed by Siempelkamp. It ensures a closed control loop for best and permanent forming accuracy without human intervention. Here, the EcoScan NEO measuring system provides support by opening up a high-resolution analysis of the basis weight distribution and a reliable foreign body detection directly after the pre-press.
