Abstract
A method and system are provided for cutting and placing individual nose wires in a facemask production line. A continuous wire is supplied from a source to a cutting station in the production line. At the cutting station, the wire is engaged with a set of driven feed rollers that advance the wire at a first speed to a cutting roller, wherein the wire is cut into individual nose wires. The individual nose wires from the cutting roller are then engaged by a set of delivery rollers to deposit the individual nose wires onto a running carrier web. The delivery rollers are independently driven relative to the feed rollers and cutting roller such that the nose wires from the cutting roller are initially accelerated and transported away from the cutting roller at a second speed that is greater than the first speed and then decelerated and moved onto the carrier web at a third speed that is less than the first speed.
