series 2000 horizontal sliding winders for cast film lines In all technical applications, the connection from continuous to discontinuous processes is a challenge, be it the takeoff and landing of a plane or the landing of a ship. In film extrusion, this interface is found in the winder, where every so often the finished roll has to be taken out and the new core needs to be started up – without interrupting the extrusion process. Turret winders are the standard solution to this problem, but they comprise some immanent disadvantages: for example, the uncontrolled winding during the turret movement which results in „indexing scrap“. Rather than fighting all intrinsic problems of turrets, the series 2000 winders eliminate indexing in the first place: series 2000 winders operate individually moveable winding stations, thus having no free web length at roll change. Due to their suitability for a broad range of applications such as paper, plastic film, and plastic sheet, these winders are used in cast film lines, sheet extrusion lines, and extrusion coating and lamination lines. Various cutting units are available for different applications and a wide range of thicknesses. Series 2000 winders are known for their solid and versatile design. Depending on the field of use, they are operated at speeds from a few meters to 600 m/min. For such high line speeds, the winders also include a built-in anti-vibration system. Any vibrations that do arise are deflected to the side walls by means of steel anchoring rods, where they are dampened down into polymer concrete. Sensitive web tension control is guaranteed by an ultra-light carbon-fiber dancer roller system.

A satellite system optimizes the angle between the wound bobbin and the incoming web, which in return minimizes the trapping of air. The center driven winder can produce rolls in both contact and gap modes to optimize the roll quality of the different films. Series 2000 winders have large 15” TFT color operating screens. The PLC offers individually adjustable winding taper curves for various products. The error diagnostics tools and a modem connection ensure easy servicing and troubleshooting by engineers of customers and SML service technicians.
