Abstract
A spinning machine having several spinning points is disclosed having at least one drafting unit assigned to each spinning point. Each drafting unit has several top rollers and several drivable bottom rollers. At least the bottom rollers which are assigned to the feeding side for the fiber material are driven by a common drive shaft extending in longitudinal direction of the machine by means of transmission devices which contain a coupling. It is provided that at least the bottom rollers assigned to the feeding side are arranged adjustably for the adjusting of the distance with respect to the respective rollers which follow while maintaining a driving connection between the common drive shaft and the respective ones of said bottom rollers.
Claims18
A drafting arrangement for a spinning machine having several spinning points, at least one drafting unit being assigned to each of these spinning points and each drafting unit containing several top rollers and several drivable bottom rollers, and at least the bottom rollers assigned to a feeding side for fiber material being driven by a common drive shaft extending in a longitudinal direction of the machine by means of transmission devices containing a shiftable coupling for selectively engaging and disengaging a driving connection between the common drive shaft and respective ones of said bottom rollers, wherein at least the bottom rollers assigned to the feeding side are arranged adjustably for accommodating the adjusting of their position with respect to the respective rollers which follow while maintaining a driving connection between the common drive shaft and the respective ones of said bottom rollers.
A drafting arrangement for a spinning machine having several spinning points, at least one drafting unit being assigned to each of these spinning points and each drafting unit containing several top rollers and several drivable bottom rollers, and at least the bottom rollers assigned to a feeding side for fiber material being driven by a common drive shaft extending in a longitudinal direction of the machine by means of transmission devices containing a shiftable coupling, wherein at least one bottom rollers assigned to the feeding side are arranged adjustably for accommodating the adjusting of their position with respect to the respective rollers which follow,
- wherein toothed wheels are provided as the transmission devices,
- wherein an intermediate wheel is arranged between the toothed wheel of the drive shaft and the toothed wheel of the bottom roller, and
- wherein the intermediate wheel, by means of an adjusting device, can be disengaged from one of the toothed wheel of the bottom roller and the toothed wheel of the drive shaft.
A drafting arrangement for a spinning machine having several spinning points, at least one drafting unit being assigned to each of these spinning points and each drafting unit containing several top rollers and several drivable bottom rollers, and at least the bottom rollers assigned to a feeding side for fiber material being driven by a common drive shaft extending in longitudinal direction of the machine by means of transmission devices containing a shiftable coupling, wherein at least the bottom rollers assigned to the feeding side are arranged adjustably for accommodating the adjusting of their position with respect to the respective rollers which follow,
- wherein one toothed belt drive respectively is provided as the transmission device between the drive respectively is provided as the transmission device between the drive shaft and the bottom rollers, and
- wherein the toothed belt drive is equipped with devices for detaching a toothed belt from a toothed wheel connected with one of the drive shaft and the bottom roller.
