In corresponding reversed supporting element 9.Bearing support is unilateral herein, that is, each corresponding rotary shaft 7 is in corresponding sieve
It draws and extends (certainly, between only one and corresponding supporting element 12 and/or reversed supporting element 9 in two front ends 10 of main body 6
Between each roller 3 or every group of roller 3 can be supported in individual supporting element 12 so as to adjust roller 3 between each other
Every；According to the reversed supporting element 9 of reversed roller and they, same arrangement is also suitable).
Core of the invention is originated from the assembled view of Fig. 2 to Fig. 4.Firstly, Fig. 2 shows the situations of drafting system 1, wherein
Roller 3 is located in their neutral, i.e. the roller main body 6 of roller 3 and reversed roller 4 does not contact.Stop in drafting system 1
While roller 3 preferably take up this position so that roller 3 and/or reversed roller 4 do not driven and ribbon 5
It is removed from drafting system 1 and/or to be removed from drafting system 1.
Before drafting system 1 is mounted with or is already loaded with ribbon 5 along transporting direction T or in the near future, 3 quilt of roller
Be moved in their loading position shown in Fig. 3, wherein this can for example by make supporting element 12 around pivotal axis 13(only
Pivotal axis 13 is shown in FIG. 3) it pivots and occurs.
Using traditional drafting system 1, where there is the shortcomings that be that each roller main body 6 is pressed against mutual mutual squeeze
Pressure is not constant (extruding force is linear in Fig. 3) along their contact area 8, because each bearing 11 has one
Fixed clearance and rotary shaft 7 usually has at least the smallest sagging.Therefore the ribbon 5 passed through between roller main body 6 exists
Unevenly by load on its width extended perpendicular to transporting direction T, so that each section of the unevenness to ribbon 5 occurs
Even traction.
In order to eliminate the disadvantage, propose within the scope of the invention now, the rotary shaft of the roller 3 designed according to the present invention
7 should have the orientation in middle position as illustrated in figure 4, this causes the roller main body 6 of roller 3 to have shared contact
Region 8 and reversely roller 4 are with common contact area 8, when the axial direction of the rotary shaft 7 along roller 3 is seen, contact zone
Domain 8 is smaller than in loading position illustrated in Fig. 3.
In this regard, as apparent from Fig 4, the roller main body 6 of roller 3 and corresponding reversed roller 4 is in middle position
Preferably only have be essentially dot shape contact area 8, wherein this can through the fact that and be carried out: roller 3
And the rotary shaft 7 of reversed roller 4 in the foregoing between form angle α in position, the angle it is of different sizes in 0 ゜ (with reference to about advantageous
The size at angle is generally described).
If the roller 3 installed in this way is moved to their middle position and pivoting supporting element 12
It is outer and be moved in Fig. 3 in they illustrated loading position, then any clearance and/or each rotation in bearing 11
The available balance of the slight bending of shaft 7, so that entire contact zone of the extruding force between roller 3 and reversed roller 4
It is all constant (ideal situation) on domain 8.Existed at this time using the clamping between corresponding roller main body 6 come the ribbon 5 guided
It is equably loaded on its width, ribbon 5 is drawn in a manner of especially uniform.
Although Fig. 4 illustrates following method, in the method, the rotary shaft 7 of roller 3 is mounted obliquely within support
In part 12, and supporting element 12 can be pivoted around the pivotal axis 13 that the rotary shaft 7 for being parallel to reversed roller 4 extends, but Fig. 5 is shown
Alternative embodiment, the embodiment are characterized in that the rotary shaft 7 of roller 3 and the pivotal axis 13 of supporting element 12 are parallel fixed
Position.In this case, in the front view of drafting system 1, the rotary shaft 7 of the pivotal axis 13 of supporting element and roller 3 is both
Angle [alpha] (size in Fig. 5 with exaggeration shows the angle) is formed with the rotary shaft 7 of reversed roller 4, the size of the angle is not
It is same as 0 ゜, as seen in the middle position in Fig. 5.Therefore, in this variant, again ensure that, when roller 3
When in their middle position, it is essentially dot shape that the roller main body 6 of roller 3 and reversed roller 4, which each only has,
