[26] the schematically illustrated expansion scheme of the present invention of Fig. 3 is in order to improve axially aligning of rubbing parts 13 and institute's feeding strip.Shown in it, draw pressure roller 9 and have the periphery sleeve 91 that is installed on the columniform axle 90.This columniform axle 90 always have two periphery sleeves 91 or 91 that belong to two adjacent drawing frames '.These periphery sleeves that have pressure roller now usually are made of the mount pad outer ring.They are made by hardened steel usually and can correspondingly be magnetized.Each periphery sleeve 91,91 ' all have elastic protective bellows 92,92 ', elastic protective bellows 92,92 ' accurately be symmetrical in periphery sleeve 91,91 ' axial length install.Have rubbing passage 14 rubbing parts 13 tights be supported on this lower roll, and be fixed in its position by magnetic force.For this reason, be provided with magnet 130, the material acting in conjunction of magnet 130 and lower roll in the both sides of rubbing passage 14.Because periphery sleeve 91 is made by magnetizable material, so rubbing parts 13 are aimed at periphery sleeve 91 with at least two magnets 130 with respect to the accurately symmetrical structure of rubbing passage 14.Fibre guide device 16 for example is located at the free end of periphery sleeve 91 and is located by guard shield 92 in the axial direction.Alternatively, for example a groove can be set in lower roll, this fibre guide device is directed axially in this groove and aims in this groove.
[27] make rubbing parts 13 accurately axially align this periphery sleeve 91 and not because of magnet 130 interaction with columniform axle 90 is interfered, this axle 90 is advantageously made by not magnetizable material.
[28] Fig. 4 illustrates this apron roller 5 and middle lower roll 6 from the visual angle of the strip of input.This apron roller 5 has periphery sleeve 51, and elasticity cover 52 is installed on the periphery sleeve 51.This periphery sleeve 51 is installed on the cylindrical shaft 50, and the another one periphery sleeve of adjacent drawing frame apron roller can be set at second end of cylindrical shaft 50.Fiber centralizer 18 with penetrating via 19 for example is installed on the side direction continuous part of periphery sleeve 51 of apron roller 5.The fiber centralizer of adjacent drawing frame can accumulate a structural unit, and the fiber centralizer is fixed by the parts of bearings that is supporting this centre lower roll in the axial direction.
[29] the present invention is that example is set forth with the drawing frame with rearmounted condenser district, this example has fibre guide device, fiber centralizer and the adjacent axle of being made by magnetisable material not of drawing pressure roller that is connected, to obtain as well as possible the axially aligning of strip and rubbing parts rubbing passage.Be appreciated that and only use the fibre guide device or with not magnetizable axle or with using the axle of making by magnetisable material not to be also included within this inventive concept set forth generally.Be correlated with therewith and point out equally, can use the fibre guide device also can fetch realization by linking to each other with the rubbing parts with other fiber centralizer in case of necessity, this fiber centralizer for example is secured in its axially aligned position by the spring force load by being different from the mode of magnetic medium.Equally, it has caused the axially aligned obvious improvement to rubbing passage and institute's feeding drawing-off strip.
