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 Roll Feeds Precise and fast positioning with lasting performance. Built with the attributes of parallel adjustment of the top roll, highprecision roll guiding and mechanical stroke limitation for fastest cycles. In combination with most modern motion control systems our Roll Feeds feature a highly reliable production support with dynamic feeding performance of max 30 m/s² acceleration. For smaller crosssections we offer the HSseries Roll Feed model This dynamic and costeffective solution makes the upgrade from gripper feeds to the much more flexible roll feed technology affordable. from coil up to 2000 mm material width and up to 8 mm thickness max crosssection approx. 2000 x 5 mm Vmax approx. 80 200 m/min max cycles with pilot release approx. 100 220 SPM from plate or bar up to 20 mm material thickness

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.
