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!
