Abstract
The invention relates to a spinning machine, the drafting arrangement of which comprises a drafting arrangement unit (35, 65, 95) with a first pair of rollers consisting of a first bottom roller (22) and a first top roller (21, 41, 71). The drafting arrangement unit (35, 65 95) is configured as an assembly which is detachably fastened to the spinning machine by means of a fastening device (11, 59). The drafting arrangement unit (35, 65, 95) is designed for one spinning station or as a twin drafting arrangement unit for two adjacent spinning stations. The unit can also include further rollers which, together with the first pair of rollers, form a drafting zone of the drafting arrangement.

A drafting arrangement unit for configuration with one or more spinning units of a spinning machine, comprising:
- a first top roller;
- a first bottom roller rotatably mounted on a base carrier, the base carrier attachable to a drafting arrangement carrier on the spinning machine;
- the first top roller and first bottom roller defining a first pair of rollers having a clamping region;
- the first top roller fastened to the base carrier via a pivotable guide arm of a load device;
- a fastening device configured to detachably mount the drafting arrangement unit to the spinning machine adjacent the one or more spinning units;
- the base carrier further comprising a first guiding device that interacts with a second guiding device on the drafting arrangement carrier on the spinning machine to position and align the drafting arrangement unit on the spinning machine;
- a tensioning device configured to load the guide arm relative to the spinning machine, the tensioning device comprising a first tensioning component that interacts with a second tensioning component on the spinning machine;
- and
- the tensioning device also configured as a component of the fastening device, wherein locking the drafting arrangement unit on the spinning machine and loading the guide arm are carrier out at least in part via the tensioning device.
A spinning machine, comprising:
- a plurality of spinning adjacently disposed spinning stations;
- a drive shaft extending along the spinning stations;
- a detachable drafting arrangement unit configured with at least one of the spinning stations, the drafting arrangement unit further comprising:
- a first top roller;
- a first bottom roller rotatably mounted on a base carrier, the base carrier attached to a drafting arrangement carrier on the spinning machine;
- coupling means for coupling the first bottom roller with the drive shaft to transmit rotational torque to the first bottom roller;
- the first top roller and first bottom roller defining a first pair of rollers having a clamping region;
- the first top roller fastened to the base carrier via a pivotable guide arm of a load device;
- a fastening device configured to detachably mount the drafting arrangement unit to the spinning machine adjacent one or more of the spinning stations;
- the base carrier further comprising a first guiding device that interacts with a second guiding device on the drafting arrangement carrier to position and align the drafting arrangement unit on the spinning machine;
- a tensioning device configured to load the guide arm relative to the spinning machine, the tensioning device comprising a first tensioning component that interacts with a second tensioning component on the spinning machine;
- and
- the tensioning device also configured as a component of the fastening device, wherein locking the drafting arrangement unit on the spinning machine and loading the guide arm are carrier out at least in part via the tensioning device.
