GOEBEL Supplies Widest Slitter Rewinder to China

Friday, September 14, 2012

Press release from the issuing company

The widest slitter rewinder in the world will soon be shipped to China and 95 Goebel employees are celebrating. The customer, China Soft Packaging Group, ordered three 11 m wide machines of the model monoslit giant from GOEBEL Schneid- und Wickelsysteme GmbH. They are intended for processing plastic films.

"The company has set a benchmark in the processing of films With this new design. accomplishment underlines GOEBEL leading technical expertise in the construction of slitter rewinders", says Dr. Ralf Enderle, Managing Director of GOEBEL Schneid- und Wickelsysteme GmbH." Engineering and Assembly, and the use of the latest technologies and materials are decisive components in the realization of such a project. A product of such high quality can only be created with teamwork between experts involved and with the inclusion of our partners on the supplier-side. This means that GOEBEL is very well prepared for the challenges of the future".

The machine is currently being packed in Darmstadt for transport to China. A total of 15 large wooden cases will be required for this; the three largest cases are up to 17 m long each and weigh up to 34 t. They contain the winding section of the machine, the slitting unit and the web infeed frame of the machine. In the next few days, the machine will reach the Port of Hamburg via heavy-goods transport. There, it will be loaded onto large container ships. It will take five weeks until the boxes reach the province of Fujian Fuzhou, P.R. China. Commissioning is planned after reassembly at the works together with the customer. During this time, a team of experienced GOEBEL employees will monitor the assembly and will be at the customers disposal for some further days for on-site training.

The 11 m wide GOEBEL monoslit giant sets new standards. Within three months, several thousand parts were assembled and more than 3,000 m of electric cable were laid. A particularly impressive component is the grooved roller. It has a length of 11,370 mm. The shaft has 5,450 grooves of approximately 1 mm width, distributed over the entire roller width. This means that it is possible to slit finished rolls, which are between 300 and 3,300 mm wide, in 2 mm graduations. Slitting is carried out using razor blades which engage precisely into these grooves.

The slitter rewinder accommodates stock rolls with a diameter of max. 1,500 mm and processes them into finished rolls with a max. diameter of 1,200 mm. The unwind width can be selected by the customer himself; it is between 9,400 mm and 10,400 mm. In future, 18 winding stations will be available for 24 h production.processes films with a thickness of 10 to 80 μm.  The test run in Darmstadt was more than satisfactory."Over the entire speed range of 0 to 1,500 m/min., the machine runs extremely smoothly", Dr. Hans-Peter Bauer, Head of Design Engineering at GOEBEL, is pleased to say. "That is unique for a slitter rewinder with these dimensions". In addition, the noise level was considerably lower than the required noise emission value.

In addition to the machine design, the peripherals and the internal power supply, for example, were redesigned too. The set-up of the machine takes place at ground level; costly foundation works and cable ducts are a thing of the past.

China Soft Packaging Group produces 350,000 tons of plastic films a year, and wants to increase its production by 50%. Convinced of the quality and the technical solutions, the customer commissioned GOEBEL with the construction of three 11 m wide machines. For years, there has been close mutual trust between the customer from China and GOEBEL. "It is a pleasure to be able to offer our customers solutions and develop these for them, enabling production efficiency and production performance to be increased" Dr. Ralf Enderle says.
