Uhing-AVS at Goodyear

As staff needed to spend time monitoring the winding processes other, more productive, tasks were neglected. This made the plant management search for other traversing Joachim Uhing KG GmbH & Co. Aiming to provide the tyre manufacturer with a smooth winding pattern in the reversing area of the traversing system known to be particularly critical, Uhing developed the automatic winding width control AVS. solutions. Goodyear Dunlop approached

Warped metal spools require frequent adjustment of the traversing width if they are to be reused. This negatively affects the cost efficiency of the pro- duction process and staff productivity. An automatic winding width control developed by Joachim Uhing KG GmbH & Co prevents the formation of bulges and dents of wires wound in the flange area of spools and relieves staff from monitoring tasks. A project the company is running in the Luxembourg plant of tyre manufacturer Goodyear Dunlop is demonstrating the efficient operation of the AVS. Metal spools, on which Goodyear Dunlop winds the 1mm to 2mm thick steel tyre cord, are used in several locations of the Colmar-Berg plant. During their service life, some of the spools change their initial geometry considerably, bent flanges being the central issue. As a consequence, many of the traversing systems, even those equipped with sensors, failed to correct the winding width and required manual intervention from operators. InnoVites BV has announced that Austech Wire and Cables (Austech) has selected InnoVites for Cable © as its ERP solution. InnoVites for Cable is the ERP software for the wire and cable industry using Microsoft Dynamics AX © . InnoVites will deliver a complete industry solution including an integration to Cimteq Ltd’s CableBuilder © software. Andrew Richmond, operations manager at Austech, commented: “At Austech Austech’s solution

Two sensors monitor the material’s line speed and the spool speed. When a dent forms at the end of a stroke, the spool speed slightly increases in relation to the constant material speed. A third sensor identifies the position of the traversing system and reports the faulty stroke end to the controller that accordingly increases the material supply in the dent area by widening the traversing width at this stroke end until the flaw has been corrected. In case of a bulge, the spool speed will decrease along with the traversing width and consequently the material supply. This results in an optimum pattern on the spool and ensures smooth unwinding later on. Since it lacks optical sensors the Uhing AVS is extremely unsusceptible to soiling, and can be integrated into existing traversing systems as a complete system or in parts. Joachim Uhing KG GmbH & Co – Germany Website : www.uhing.com we were looking for a business solution that addressed the special requirements that are typical to our industry, such as length and tolerance management, copper management and integration to our cable design software. We found InnoVites to deliver exactly this!” InnoVites will work with local partner Eclipse Consulting to implement the solution for Austech.
