The specific embodiment

Top cradle 1 shown in Fig. 1 to 3 is the part of only making the illustrated drafting system of part of a spinning machine, for example ring throstle.This drafting system in fact only illustrate one group of apron roller to 2,3 and one groups of delivery rollers in the back to 4,5.Staple fibre 22 for the treatment of drawing-off in the direction of arrows A be input to the apron roller to 2,3 and in the direction of arrows B leave delivery roller to 4,5. for the present invention, whether whether the apron roller is placed in other roller of drafting system to 2,3 is configured in other roller to upstream or delivery roller to 4,5 the downstream is all had no relations.Roller 2 and 4 is the bottom rolls that vertically are subjected to continuous transmission along machine, and roller 3 and 5 is pressurization rollers, and they lay respectively at apron 6 and upper leather ring 7 under each spinning spindle position a or the b. (only representing with dotted line among Fig. 3) and are disposed at apron roller 2 and 3 in a known way.

Following apron 6 has one as apron platen 8 under the what is called of steering mechanism, and by a tension element 9, such as a roller tensioning of bearing elastic load support.

Respectively for the common top cradle of two adjacent spinning spindle position a and b (see figure 3) configuration as two framves. this cradle is used for leading for two adjacent upper leather rings 7, wherein respectively between spinning spindle position a and the b, top cradle 1 supports on the position of the fixed axis 13 that arc 14 is bearing in apron pressure roller 3 by one.With spring element that loads for top cradle 1 of 15 marks.

Top cradle 1 has the matrix 10 of two spinning spindle position a of an extend past and b, and this matrix has support part 12. an aprons commutation guiding piece 11 that is used for each apron commutation guiding piece 11 respectively for each spinning spindle position a and b and clamp tight support part 12 of being attached troops to a unit as the background technology that the front has been described.

The different fibre lengths if stretch on same drafting system need mutually adjust the apron roller usually to 2,3 jaw line 23 and the delivery roller spacing to 4,5 jaw line 16. and this is normally being replaced by prerequisite for top cradle 1.

Now top cradle 1 so is matched with each spinning spindle position a, b... according to the present invention, make each top cradle 1 that a thick-and-thin matrix 10 be arranged, the apron that always is complementary commutation guiding piece 11 is supporting part 12 places to be arranged on this matrix by replacing. therefore each top cradle 1 has the different apron commutation guiding piece 11 of a cover.A kind of apron commutation guiding piece 11 ' of selectively design dots in Fig. 2 and Fig. 3. do not need to change whole top cradle 1 like this, and only change each apron commutation guiding piece 11, wherein even can design like this, when the fibre length difference is not very big, upper leather ring 7 can keep in case of necessity. under any circumstance, because removable apron commutation guiding piece 11 can guarantee to be matched with all the time for fiber the good guiding of fibrous material between the outlet side terminal of apron guided plate and delivery roller are to 4,5 jaw line 16.

Especially as can be seen from Figure 2, mutual removable apron commutation guiding piece 11 or 11 ' or other not shown commutation guiding piece can clamp bindiny mechanism by one and change mutually easily, wherein containing the matrix 10 of supporting part 12 keeps all the time. clamp preferably a kind of clamping bindiny mechanism of effect in the back of bindiny mechanism 17, this so realizes easily, be that apron commutation guiding piece 11 is made by a kind of elastoplast, this guided plate has one and goes up tong arm 18 and a following tong arm 19.Last tong arm 18 can be provided with the avris commutation leader 20. of guiding upper leather ring 7 in the known manner

Can see also that from Fig. 2 following tong arm 19 has one to attach troops to a unit in the following distance block 21 of apron 6, its position to the support part 12 of matrix 10 with all remain identical to apron platen 8 down for apron commutation guiding piece 11, all modification of 11 '.For this reason, distance block 21 has a plane at it on the side of following apron 6.

In modification according to Fig. 4 and Fig. 5, current as example until now, an apron commutation of configuration guiding piece 11a on identical support part 12, this apron commutation guiding piece shifts out beyond the draw zone plane upper leather ring 7 downward biases. and for this reason, this apron commutation guiding piece has settled a projection 21a. draw zone plane down by roller two jaw lines of 2,3 and 4,5 to be determined.In order to contrast, in Fig. 4, dot previous described apron commutation guiding piece 11.
