STRIEBIG CONTROL - impressive dimensions, high performance
46 square metres of composite material panels cut to size on an area of just 100 square metres. Kögel PurFerro GmbH & Co. KG realises this at its work in Duingen. This is possible with the vertical Striebig sawing technology.
Vertical sawing technology ensures high productivity
Kögel PurFerro saws composite panels for refrigerated bodies or trailers. The company uses a specially designed CONTROL 16301. The cutting area: 15,300 mm x 3,010 mm with a cutting depth of up to 103 mm. From the production of the large-format sandwich elements to the customised cutting and delivery of the finished elements for the superstructures - PurFerro produces the panels next to the cutting hall. Short distances and optimum utilisation of space ensure high productivity.
Challenging project for the partners involved
The CONTROL is one of the largest Striebig saws ever installed (cutting range: 15,300 mm length / 3,010 mm width). The panels to be sawn required specifically designed saw components. Support rollers were made of steel instead of aluminium. Components were supplemented or reinforced in order to optimise the full performance of four-sided edging with the 4SB function. A minimum quantity oil spraying device supports the clean cutting of the steel cover layers. The dust extraction system realised with Höcker Polytechnik GmbH uses special filter technology.
Solution fulfils high requirements
"From the basic idea to the first saw cut with the new Control, we worked with Striebig on the project for just under 1 ½ years. The hot phase took around 6 months for assembly and familiarisation. We have come to appreciate the employees involved from Lucerne as phenomenal partners", Tobias Flessel, plant manager in Duingen, is highly satisfied with the process and result.

CONTROL - impressive dimensions, very high performance
The career of the panels to be sawn (sandwich elements) begins horizontally. The elements consist of a polyurethane insulation core (100% CFC-free), which is blown in, and an inner and outer cover layer. A 0.6 mm thick steel sheet is used for each of the cover layers. On the inside of the refrigerated body, the sheet has a smooth and food-safe rigid PVC film coating that is easy to clean. The outer sheet is end-coated. ‘We have continuously expanded the expertise for our vertical saws in over 60 years of company history. Originally used for cutting wood-based panels or solid wood panels, our vertical technology is now being used more and more for other materials,’ explains Andreas Müller, Striebig's Area Sales Manager for Germany. In addition to wood, the reference list also includes non-ferrous metal panels for aircraft construction, a variety of plastic panels and panels made from a wide range of composite materials. They can be cut to an accuracy of 1/10 mm using vertical cutting technology. The decision to use a vertical saw for panel cutting at PurFerro is based on the production process. The horizontal production of sandwich elements requires space. This ‘disadvantage’ must be compensated for when cutting to size. After the insulation layer has hardened, the sandwich panels are stored horizontally in the cutting hall. Using a vacuum lifting system attached to the ceiling, a single employee can easily place and align them on the vertical saw. The upper and lower trimming cuts are fully automatic. This is ensured by the ‘4SB’ option, which enables automatic four-sided edging, in combination with the standard electronic positioning system for automatic adjustment of the height dimensions (EPS-Y) and the automatic upper edging cut (ABO). The vertical cutting dimensions are stored in the Control software, are automatically approached by the saw and the cut is executed automatically. A single operator monitors the work of the saw and finally removes the cut panels from the saw using the vacuum lifters. The one-person operation propagated by Striebig also works with oversized and heavy panels.
