If you need two Coil Reels to hold one coil, you need a Heavy-Duty Coil Feed Line above all. One that is designed extremely robust and knows to subdue even materials of highest bounce and largest cross-sections.To ensure this, we have taken no heed to cost savings but went by the maximum principle: 2 Coil Reels with high-performance arbors retain the coils from left and right. 2 x 2 hydraulic arms secure them from top and bottom – each with eight tons pressure force, each with hydraulically driven snubber roll. The loading is done with one central lifting gear built into a super-duty running frame for the V-nest. Hydraulic manipulators with pivoting and bending function support the threading of the material. On the receiving end, a Pre-Straightener with 200mm work rolls takes over, after hydraulic edge guides have ensured central entry. Now, if someone asks us our definition of “heavy-duty”: We find 36.000 kilogram coil weight and 2.

A perfect combination of space savings and dynamics: the GSW Compact Feed Lines Our Compact Feed Lines are an ideal answer to the challenge of a constraint floor and necessity to process thick materials. Marrying the processes of leveling and indexing into one Feeder-Straightener machine allows for a complete Feed Line with only two individual machines and thus greatly reduces the necessary length. Additionally, the decoupling of the coil mass from the indexing process – achieved through a short loop between Coil Reel and Feeder-Straightener – enables dynamic feeding despite the compact footprint. And, if cross-sections are especially big, the loop can be spared completely, creating yet more space. One more advantage, virtually a by-product out of their very nature, is the quicker set-up of our Compact Feed Lines. This elevates them to not only space- but also time-savers!

With Conventional Feed Lines, the focus lies on speed and material surface. That’s why Conventional Feed Lines are equipped with a Coil Reel for pull-off, a Straightener with variable frequency drive a coil loop and a Servo Roll Feed: the loop uncouples the more inert straightening process from the highly dynamic indexing process and thus allows for high line speeds and preservation of the material surface. Since productivity and capacity demands can vary significantly, we have created different control concepts: while small Feed Lines work with a simple pneumatic drag brake at the Coil Reel and an ultrasonic sensor to control the Straightener speed, the large Feed Lines get fully synchronized controls with motor-limited Coil Reels and a smart loop, creating a steady average speed of the whole line. This allows smooth pull-off of high coil weights while the loop remains very calm – in addition, the Servo Roll Feed can work with full dynamics, even at long indexing progressions.

Most Winding Lines process one single coil (single-layer winding). There are however also applications where multiple layers are wound: With this process, the rewinding Coil Reel (Rewinder for short) reverses horizontally and orderly puts one layer beside the other, creating one long coil. This will make sense when narrow slit coil materials of small weight and – depending on their thickness – usually short running lengths would require frequent changeovers. Here, a layer-wound coil provides much longer productive time. The “elongation” by the way is done by butt-welding the coil strip ends. We offer this complete technology – including our own end-joining equipment and an adapted servo layering axis for the Rewinder. For thick strips we build vertical straighteners to correct the frequently occurring camber defect.

When you deal with industrial surface treatment and your expertise is the cleaning, brushing, polishing or coating of strip steel, you most likely do not want to spend any worries about the run of the material. That’s where our Winding Lines keep your worries away – because they take care of a safe run! They work with high tension and special monitoring and deflectors to do this, with the result of a clean wound beginning to end. The machine design thus calls for especially high drive power and precision expansion systems; even something so simple as the machine base is designed special to cope with the forces… To control the precision of one layer to the next, we utilize external edge controls and servo-drive the Reels for adjustment. This way we meet the typical low tolerances in this industry – after all, the coil is the product!

Upenders are designed to safely tilt big and heavy coils – either from horizontal into vertical or reversed. This fast and easy coil handling solution gets rid of “adventurous” tilting methods that often will endanger the operator. Chains and other lifting aids which damage the coil rims become obsolete. Upenders allow 90 degrees tilting of coils; Combination machines will also rotate 180 degrees. Both can handle up to 25 tons.

GSW Shears find their place in CutToLength Lines or as Scrap Choppers. They are used to perform lasting and costefficient, no matter the roughness of the environment. Our pneumatic and hydraulic Shears are designed efficient in any way – and from 60 to 1500mm width The pneumatic machines run with up to 500 SPM while their heavy types are robust enough to lastingly process up to 3mm thick materials. Since they do not need hydraulic power or electric controls, they are extremely costefficient. If a combination of high SPM and thicker materials is necessary, our TSHL „light“ hydraulic Shears offer the solution. The TSHS series machines are built very heavy and stiff which allows them to cut up to 12mm thick materials. If yet larger widths than 1500mm are to be processed, we work together with most reliable German partners who supply us with highquality Shears in hydraulic, electric or servoelectric design. This way we can offer the very best suitable solution for any application.

Coil Cradles are made to help unwind coils in rough production environments. Mostly combined with a straightening unit, they work with narrow and thick materials. Built to last, Coil Cradles offer quite a few advantages Simple handling of even hightensile materials with strong clockspring, short setup times, an elaborate coil handling concept which gives a chance to rewind of unfinished coils. By using serial straightening units, type RMA and RMZ, everything is well fitting. To achieve short mounting times and easy accessibility, the complete machine body features a one piece tiebar design machined with most modern CNC equipment. Coil Cradles, CradleStraighteners and CradleFeederStraighteners thus are very efficient too. Consequently, their compactness, efficiency, safety and operator friendliness melt into a coil handling solution which underlines GSW’s lead in technology.

GSW FeederStraighteners, series VRMA are just as simply operated as our Straighteners of the RMA series. With servo drive and length measuring system they offer the additional functionality of material feeding (positioning) over just straightening. Their most common application is cuttolength and spacesaving coil feeding. The already revolutionary alligatorhead can be extended with hydraulic opening for full piloting when feeding into stamping presses with progressive dies. For especially heavygauge materials or high demands in flatness, our VRMZ series FeederStraighteners are the correct answer. They process crosssections as large as 2000 x 5,0 mm. up to 2000 mm material width and 16 mm thickness max crosssection approx.. 2000 x 5 mm or 650 x 10 mm max net output approx. 50 – 150 m/min max cycles with piloting approx.. 40 – 100 SPM

When straightening becomes core competence and strip or parts need to be completely removed of their tension, GSW Precision Straighteners are the answer of choice. They handle up to 2000mm wide and up to 6mm thick materials in strip or plate. Highest stiffness, closest centerdistances and the active driving of all rolls allow for perfect flatness results. Our newest development – the HighPerformance Straighteners, series RMB – answer questions raised thru current material development leading to increasing material strength, lessening thicknesses or the use of sandwich materials Their enormous stiffness, large pinch rolls and closest center distances evenly deliver highest straightening forces. If material surface quality must be fully preserved, the 6high design option is the right choice. Here, intermittent rolls prevent marking caused by the backup rolls and allow for a perfectly clean strip or plate.

High quality, extremely simple operation, unreached price/performance ratio For decades, the GSW Straighteners are valued all over the world. The Straightener with clamshell head (the GSW “AlligatorHead”) came out in 1968 – the RMA series – and today is being built in up to 2000mm width. This machine levels coil set and equals out tension with up to 12mm thick materials. It has given GSW a pioneer’s position in the industry. The RMZ series Straighteners convince where high straightening and pull forces are needed. Its frametype head design provides a high stiffness and elevates this technology to work with high demands in straightening quality – even with highertensile materials.

Special Reels are a longtime part of the GSW lineup Our Horizontal Reels (also called “Pallet Decoilers”) for instance, are helping to unwind lying coiled materials. They are best suited for thin strip which often is loaded together with the carrier pallet. GSW Tilting Reels make sense where normal coil loading is difficult or the materials don’t allow that process. Instead, the coil is loaded horizontally and uncoiled vertically afterwards. Paper Winders help to safely process paper interleaf or film coatings innovative expansion and clamping units help for quick and simple handling. Performance Data up to 3t coil weight and max approx. 2mm thickness max crosssection 300 x 2mm max winding or payoff speeds approx. 20 – 100m/min
