Description

FIG. 1 of the drawing shows in terms of a tpalny machine equipped with the proposed device; in fig. 2 is a side view of it; in fig. 3 shows it from the end and in FIG. 4 and 5 parts fixture.

M lka 1, of any design, delivers bundles of m flax to table 2, where they fall between two, one above another lying, endless clamping belts 3 and 4, which capture the beams close to the middle length of the latter and push them horizontally straight along the table 2, so that the longer, free ends of the bundles are guided between a pair of rotating drums 5 and 6, equipped with twelling blades. It is important that the bundles, in their horizontal position, are processed from the middle to the ends, since only in the horizontal position the individual fibers lie freely next to each other, and the stems lying inside the bundles are well cleaned. When the vertical (hanging than) the position of the fiber bundles.

the latter, during the scooping process, are pressed tightly against each other, and the fibers inside the fiber are not cleaned, so with such constructions it would be necessary to carefully lay flax stalks next to each other in order to achieve a suitable cleaning, would give the same relatively low productivity and greatly increase the cost of work.

Each reel drum consists of several, evenly distributed around parallel axes 7, 8, shoulders, which are provided with burrs 9, 10. The shafts 7, 8 rotate at the same angular velocity, but in different directions. The distance between the axles of the shafts is less than the double outer radius of the scutching knives, which in each of the drums are spaced apart from each other so much that, during their movement, they do not interfere with each other. The working branches of the clamping, transfer belts 3, 4 are parallel to the shafts 7, 8 and, in general, lie at equal distances from them. The dimensions are chosen so that the places of the beams, on which the knives 9, 10 first act, are somewhat further than the middle of the length of the beams.

After advancing the bundles clamped with transfer tapes 3, 4, the already cleaned half of the bundles are clamped between the other two transfer clamping tapes 11, 12, and carried out further, between a pair of scutching drums 13, 14, which in all respects is similar to a pair of breakers drums 5, 6 but it is located on the other side of the table 2 and rotates in the opposite direction than the scutching drums 5, b. The other halves of the bundles are cleaned with the indicated scutching devices as the first halves, using the scutching devices 5, 6. After exiting the clamping transfer tapes 11, 12, the cleaned fibers fall on the folding board 15. The device of the clamping transfer tapes 3, 4 is the same as the tapes 11.12. They are endless ribbons with longitudinal protrusions and hollows and are made of rubber, leather or the like. These tapes can also be made by attaching rubber ribbed linings 31, respectively 41 (Fig. 4), to a leather belt. The longitudinal ribs of one tape can enter with some slack into the grooves of the other tape, as shown in FIG. 4. The belt 3 passes through the guide roller 17 to the roller 20, and the belt 4, in contact with the first one, passes from the guide pulley 18 to the guide pulley 19. These two, moving at the same speed and in the same direction, are part of the belts They are working branches, between which tufts 32 can be clamped (Fig. 4). The working branch of the tape 4 is guided in this way by the groove 24 of the bed, and the working branch of the tape is 3-part of the bed 25 and pressed against the branch

the ribbons 4 by the rollers 26 mounted in the frame 27, which in the part of the frame 25, perpendicular to the belt 3, have some play but are prevented from moving with the belt. Every two rollers 26 are interconnected frame 27 (Fig. 5).

Part of the frame 25 encloses the sleeve 28 filled with compressed air, which rests on the upper pads of the frames 27 and by means of the latter presses the rollers 26, respectively, the tape 3 to the tape 4, with which it moves together, due to friction, which is regulated by changing the pressure in the air sleeve 28 The mentioned device should be preferred to the springs, since it achieves a more uniform and more accurate adjustment of the pressing of the working branches and, most importantly, it is possible to move the action closer. ny knives to tapes 3, 4 and, thus, to receive small length of perekidka.

As soon as the beams are between the roller 20 and the pulley 19, they must be slung, i.e. they must fall between the belts 11, 12. To do this, on the same axes on which roller 20 and pulley 19 are mounted, roller 23 and, respectively, pulley 22 are mounted. The latter rotate in the same direction and with the same peripheral speed that and roller 20, respectively. 19. Roller 23 and other guides, rollers 30 move clamping scotch tape 11, and on pulleys 22, 33-clamp scaffold tape 12 with which the device clamping the tape 11 to the tape 12 is identical with the above for tape 3 and 4. Therefore, as soon as the beams are between roller 20 and pulley 19, that part of the beams The torus has already been cleared by the scutching devices 5, b, it will now be automatically captured by ribbons 11, 12, and the beams will move further. Clamping support strips 11, 12 are offset
