  • Patent number: 5762254
    Abstract: A mechanism is provided for receiving a web with intermittent motion and converting it to uniform motion, particularly for severed carton items. A reciprocating carriage has first and second adjacent idler rollers and a third idler roller spaced away from the first two. A driven roller has a fixed axis and is located with respect to the third idler roller such that the web when strung between the first and second rollers and thence around the third roller and thence around the driven roller, assumes a quasi-boustrophedonic configuration such that the portion of the web between the third idler roller and the driven roller decreases when the carriage moves in the direction which decreases the distance between them. Upper an lower endless belts pass partially around the first and second rollers, thence around the third idler roller, thence around the driven roller, thence along different respective return paths.
