Abstract
1354653 Looms WEEFAUTOMATEN PICANOL NV 25 Feb 1972 [26 Feb 1971] 8828/72 Heading D1E Warp let-off is controlled by measuring the pick density, the warp tension and beam diameter and converting these measurements into electrical signals which are fed to a transistorised circuit controlling the electrical motor letting off the warp. The pick density is measured by magnetically or optically monitoring the teeth on a gear wheel 22 on the takeup motion, the warp tension is measured by a straw gauge 33 and the beam diameter by a potentiometer 30. Provision is made for reverse driving and the gear train on the takeup motion is variable to control pick density. The electrical circuitry compensates for shedding tensions.
