Research notes

The servo scroll: each set of yarn-feed rolls on a scroll attachment gets its own independently controlled servo motor, plus a computerised design system to handle 'the large numbers of individually controllable design parameters'. This removed the old chain-drive limit of two or three stitch heights per pattern. Family members: US6283053 ('independent single end servo motor driven scroll-type pattern attachment', filed 20 Dec 1999); US6439141 ('Independent single end servo scroll pattern attachment… and computerized design system', a divisional); US6516734; US6877449 and US7089874 (servo-motor-driven scroll attachments). The EP counterpart is EP1132514, which names Tuftco Corporation, Chattanooga, as proprietor. Later patents call these 'the single end servo scroll of Morgante' and set them beside Frost's double-end servo scroll (US6550407, filed Aug 2002).
