WINDING TECHNOLOGY SERIES W3000 CAST SML winders – technology that sets new standards SML winder series W3000 is designed for both a maximum roll diameters of 400mm required for 3-inch jumbo rolls and the production of 2-inch hand stretch rolls. Moreover, the W3000 incorporates a unique SML innovation, as the individual winding cores are each supported by a pair of arms. Therefore, no winding shafts are needed and critical shaft speed has ceased to be an issue. This latest generation of SML’s most innovative winder is now available and offers a fundamental design improvement, as the number of winding stations has been doubled from two to four. This means that turret the indexing angle during roll changes has been cut from 180 degree to 90 degree and the cycle time has been slashed from 30 to a mere 17 seconds. The mechanical design of the winder makes it extremely straightforward to operate and easy to service. All the electric drives and electrically operated solenoid valves have been moved from the indexing turret to the winder´s basic unit, thus removing the need for a rotary commutator joint. All that remain are pneumatic control conduits for the opening and closing of the winding arms, a design renement that greatly simplies adjustments for different roll widths. The new design also offers benets in the following areas: • Increased efciency 4-station design enables the production at full speed of extremely short rolls in lengths of less than 200m. As the rewinding of small rolls from a mother roll is no longer required, this provides a genuine boost to production efciency. Improved roll quality Good winding quality is maintained during indexing by means of a special, auxiliary contact roller and the shorter 90 degree indexing angle derived from design 4-station. An optional solution for coreless winding is available. Thin core technology A number of improvements have facilitated a reduction of the minimum core wall thickness to 3.5mm. This results in massive cost savings, especially in the case of short rolls. SML winder series W3000 is available in standard 4-up, 5-up, 6-up and 8-up widths and as reected by the sales gures, their design sets new standards with regard to functionality and winding quality.
