DEVICE FOR COORDINATION OF FABRIC POSITION Russian patent published in 1998 - IPC

FIELD: mechanical engineering; device can be used in other industries for coordination of articles made of textile-like materials. SUBSTANCE: positioning of fabric selvages is effected with the use of feed, outlet and operational conveyers or other similar units. Used as retainers are either contactless sensors or stops. Disadvantage of these devices lies in that the change of direction of the textile-like articles is complicated and alternating. The proposed device allows the alternating change of direction of the article movement to be used for improving positioning accuracy. For this purpose use is made of operational conveyer 3, in which bearing surfaces are formed by threads stretched on independently controlled cylinders 7 combined into a drum with the use of bearing 9 and pin 10. EFFECT: accurate positioning of textile and textile-like materials in processing machines. 1 cl, 2 dwg
