ITW Dynatec’s Vector Advanced Metering Platform solves the problem of a time delay created by the pressurization of these hose networks causing a reduction in pressure during startup and a reduction of adhesive on the product until run-time pressures are achieved. A Vector metering station with patented radial drive precision pumps is mounted in close proximity of the application point. This allows for short hose runs between the metering device and the applicator; thereby reducing the time required for full pressurization. Additionally, the pump base of the metering station can be fitted with a variety of application devices for the direct application of adhesives to various substrates, eliminating the hose runs completely. Also, unlike conventional remote metering stations, the patented Vector platform allows up to six individual hose outputs per drive to meter individual flows to each application device. Conventional metering stations on the market today only allow one individual or one dual meter per drive thus requiring additional equipment and increasing cost of ownership.
The Vector platform’s flexibility facilitates a variety of pump configurations to meet strict production requirements. The metered pumps are mounted on twenty-five millimeter centers, all of which are driven by a common motor, and ensure cross-web accuracies of up to ±0.5%. The adhesive supply to the metering device is isolated from the application point and eliminates the requirement of exact metering from the adhesive supply unit. ITW Dynatec has created a high volume adhesive supply unit, the Vector Melter, equipped with a piston pump sized to deliver a large volume of adhesive over a great distance. A patented hot melt pressure regulator conditions this bulk adhesive feed into a consistent feed with little or no pressure variation to one or more metering devices. The Vector distribution and metering system eliminates the problems associated with long hose runs while increasing the accuracy and versatility of metering systems.
