Slitting & Rewinding


Scheduling and slitting optimisation S


iam Kraſt Industry (SKIC) has appointed Greycon to update its scheduling and slitting optimisation


in its three mills in Thailand. SKIC is the biggest manufacturer in Southeast Asia with a production of 2.3 million tons of packaging paper annually. Greycon first got involved with SKIC in 2006 when it was contracted to provide scheduling and slitting optimisation in it mills in Thailand. Because of the benefits SKIC has achieved in improved trim, scheduling and machine utilisation, visibility, delivery time of orders and supply chain optimisation, SKIC included two new sites to the original project scope. The system is integrated fully with SAP. Jakkrit Supawatanakul, CEO of Greycon’s


Partner in Thailand, Forward Consulting says: “We have enjoyed a long and successful relationship with Greycon. In


order to be the leading manufacturer in Southeast Asia, as well as continue to contribute to sustainable progress, SKIC needs to ensure its mills are equipped with the latest technology providing innovative solutions enabling them to maximise


efficiencies wherever possible. Due to results and benefits Greycon’s solutions have provided over the years, it is important they remain up-to-date.” During the upgrade, Greycon installed its new version of X-Trim rewritten in .Net and its new generation of scheduling software, opt-Studio, substituting the old S-Plan installation. The new version of the software provides


better and faster slitter optimisation with X- Trim state of the art algorithms; and faster and more user-friendly scheduling functionality which comes with opt-Studio. Andres Bonelli, project manager at


Greycon says: “Having been part of the original project back in 2006, it was exciting to roll out the upgrades and experience first-hand how SKIC’s business has grown and evolved over the years.” siamkraſt.com


manufacturers of paper and board, film, tobacco paper, alufoil and aseptic packaging, has developed the a new slitter rewinder INTERSLIT BSF. The machine is specifically designed to


process hyper sensitive materials such as battery separator film also based on wet- process BOPE. To ensure the best results, the slitter rewinder offers several state-of-the-art features and options. The especially compact station rewinder concept with a short web path from unwind to rewind keeps the web on track and allows lowest web tension ranges. Thanks to the ergonomic design, the machine is functionally accessible all-around and thereby ensures highest productivity during unloading and set-up.


Handling sensitive material with ease G


OEBEL IMS, a manufacturer of slitting and winding solutions for both producers and


To guarantee best results, the


developing engineers focused on achieving the maximum of precision and efficiency. Therefore, high end components such as all carbon fiber and individually driven rollers, as well as an absolute precise and sensitive web tension control system, are integrated in the INTERSLIT BSF to ensure the proper handling of such valuable and delicate substrate like BOPE based battery separator film. To achieve the targeted finished roll quality, the contact force is individually adjustable from gap winding up to sensitive contact winding. All finished rolls are carefully rewound on individual rewind stations which are positioned fully automatic and are all arranged on one common side of the slitter rewinder. These stations open automatically and release the finished rolls


into a rest position, where the operator or optionally an automatic handling system will clear the rolls from the unloading position. Thus, an easy and fast unloading and inspection of the finished rolls is guaranteed. The INTERSLIT BSF is tailor- made for every customer. It provides a maximum web width of up to 6,000mm while unwind and rewind diameter as well as speed are adjusted upon customers’ needs. The top solution for most precise and dust reduced cutting are individual driven shear top knifes which are embedded in a carbon fiber body bottom cutter shaft that also can be driven independently. Additionally, knife de- dusting systems and double side web-cleaning devices downstream the unwinding unit are available. goebel-ims.com
