Claim 0:
1. A drafting system (1) for a textile machine for drawing a strand-shaped fibre band fed to the drafting system, comprising:
a plurality of roller pairs arranged in succession in a running direction (A) of the fibre band, each roller pair of the plurality of roller pairs comprising:
a top roller (3);
a bottom roller (4); and
an individually adjustable weighting device (40) configured to apply a load to the top roller (3) of the plurality of roller pairs
wherein:
the bottom roller (4) is mounted and held in a housing (2) of the drafting system (1), and
the top roller (3) is mounted and held in the housing (2) of the drafting system (1) via a top roller carrier (30) configured to be pivoted about a rotary axis; and

a swiveling weighting arm (20) configured to be brought into an open position and a closed position,
wherein:
the weighting arm (20) comprises the individually adjustable weighting device (40) for each roller pair of the plurality of roller pairs, configured to apply a load to the pivotable top roller carrier (30) in a weighting position when the weighting arm (20) is closed,
the weighting device (40) comprises a convex load head (42), and
the load head (42) is capable of being moved and attached to the top roller carrier (30) in various positions along the running direction (A) of the fibre band, such that a point of application of the load by the weighting device is capable of being brought into a desired position relative to the top roller carrier (30) and fixed in place.
