DEVICE FOR WINDING FILTERING ELEMENTS Russian patent published in 1998 - IPC

FIELD: filtering elements produced by winding threads onto perforated sleeve. SUBSTANCE: winding of endless thread onto a sleeve rotating round its axis is accompanied by simultaneous displacement of the thread along the sleeve axis with specified constant relation between the angular speed of the sleeve rotation and the speed of the thread reciprocation along the sleeve axis. When diameter of winding reaches a definite specified value, relation between the thread winding speed and speed of its reciprocation along the sleeve axis is changed and then is maintained until the winding process is finished. The winding device has housing accommodating bobbin carrier and thread carrier both of them being mounted to rotate on supports, and drive switch operating, when the winding reaches specified diameter. Seated on the shafts of the bobbin carrier and thread carrier are disks associated kinematically with each other and with the drive. The device is provided also with selector switch intended to change direction of the drive rotation, two freewheeling clutches and a pair of additional disks. One of the freewheeling clutches is mounted on the shaft of the bobbin carrier and the other on the shaft of the thread carrier. The disk of the bobbin carrier shaft is disposed on the outer holder of the freewheeling clutch. One additional disk is installed on the bobbin carrier shaft and the other on the freewheeling clutch of the thread carrier. Both the disks are linked with each other. The additional disks are made in the form of toothed wheels. EFFECT: improved efficiency. 2 cl, 1 dwg
