i-cmm. (cue-s4) v The present invention'relates to the extraction of burrs from textile fibers on carding machines,
I and more particularly the extraction of burrs on cards for wool, especially. worsted.
5 h It is knownthat the-object of the burrlng operation is to eliminate vegetable waste, straw,"
burrs, etc. generally known as .burrs.
This operation is carried out on carding machines by an assembly of separating and clean- 10 mg members forming. the burrlng motion of the cards, and generally comprising a crushing roller and a burrlng roller;
With a view to increasing the refining action of the burring operation according to the nature' which comprise a number of successive burrlng devices operating on the 'materialimder treat- 'ment and driven at successively higher speeds. A more special arrangement has been evolved, 5 which is known as the "Morel burrlng motion,
placed in front-of the carding cylinder or cylinders and employed more particularly on worsted The-Morel burrlng motion is disclosed in Patent No. 254,583, of- March 10, 1896 so and the'addition' thereto of 1898; and alsodisclosed in British patent to Morel, No. 28,734, of 1897. These "Moi-e121 burrlng motions are formed essentlally by the combination of a bristle roller, a a crushing roller which receives .the material from the bristle roller, and a burrlng roller. This "More? burrlng device separates the work of burr removal into a distinct operation independent of the carding, and it comprises a bristle on roller which is made much,too flexible to exert ",3! action. It is placed between a licker incl 8. breastroller and the carding cylinder and exertsnocardlngaction.",
. In spite of the known advanta es of the a efllcrel burringmotion it still possesses certain disadvantages. .In particular it has to be'adiust ed to the quality or the origin fibers to be treated, 11: does not meme or heavy immn-lue sumciently when the 1 working speedfadopted is slow oritoo' fast, a certainquantity of good peers, varying tiigthe working speed, is carried away with the 'rheobie'ct'ofthe presentinventionistoremove It ofllorelburring motion, and it is based on the following observa When these devices are working athigh speed, the heavy impurities carry along with them a greater quantity of good fibers than when the extaction of 'burrs'is extracted at a slower speed. Moreover, the mechanicalimpact at high speed of the blades of the burrlng roller on the fragile and heavy impurities most frequently causes them to be broken up. into small fragments instead of being thrown out of the card, and these small fragments then remain in the material treated during the carding operation.
Moreover, it has also been observed that when a Morel motion is working at slow speed, it not separate out the light impurities;
Now the object of ,the'invention .is-to subdivide the work performed by aMorel burrlng motion. With "this object in view the invention consists'in an improved Morel burrlng motionwhichis characterized by the feature that it comprises two or 1 more bristle rollers, two or more crushing rollers and two or more burring rollers, these members being arranged intwo or more groups arranged in-sequence and each comprising a bristle roller, a crushing roller and a burrlng roller, 'while each successive group works at a suitable increasing speed, this speed being slow in the case of the first group, faster for the second, and so on. By means of these improvements the various types of impurities are extracted successively by the subdivided operation of the various groups.
.n These results are obtained by the fact that,
during the passage through the first group, the
heaviest impurities,(burrs, small nuts, fragments of skin, etc.) on account of their weight and/or 40 their size, are extracted without being broken up by the blades of the burrlng roller turning at slow speed, while during the passage of the second group, the lighter impurities (straw, splinters, etc.) which still remain are, on account of their small weight, extracted by the more rapid motion of themembersof the second group, and so on.
In order to make the invention clearly understood and by way of constructional example, one
embodiment is hereinafter described and is lllustrated in the accompanyin drawing, which shows .a side elevation of a carding machine having the improved burring motion fitted thereto.
In" the drawing, 1 is a breast roller and 2 the carding cylinder or main 5 Between these two members, and in place of theusual separating and cleaning members, or again in place of a Morel burring motion of known type, is mounted the improved Morel burring motion formed, according to the invention, by a bristle roller 3, a crushing roller 4 with its burring roller 5, a bristle roller 3, a crushing roller 4' and its burring roller 5. 6 is a transferring roller conveying the cleansed fibers to the cylinder 2, and i and i are the troughs receiving the impurities or burrs extracted by the burring rollers 5 and 5'.
The first three members 3, 4 and 5 are given a relatively slow speed so as to form a first group working at a slow speed.
The next following three members 3, 4' and -5' are given a relatively high speed so as to form a second group working at an increased speed, the driving pulleys of these members having suitable diameters for this purpose.
The two barring mechanisms, in series arrangement, are interposed between the breasting roller l and the carding cylinder 2. In the first mechanism, or group of associated burring elements, the bristle roller 3 operates to convey the material being treated from the breasting roller l to the crushing roller 4i, which coacts with the beating roller 5 to eliminate the extraneous matter. The beating roller 5 contacts with the associated crushing roller i between the bristle roller 3 and the bristle roller 3' of the second burring mechanism. In the second burring mechanism, the bristle roller 3 transfers the material from the crushing roller i to the crushing roller 4, which coacts with the beating roller 5' to eliminate the remaining extraneous matter. The beating roller 5' contacts with the associated crushing roller 5 between the bristle roller 3' and the transfer roller 6, which operates to convey the material, freed from the extraneous matter, to the carding cylinder 2 for further treatment.
Means, well known in the art, are provided for driving the first burring mechanism at a slower speed than the second or succeeding burring mechanism. By driving the first burring mechanism at a comparatively slow rate of speed, the coaction of the beating roller 5 with the crushing roller 4 tends to eject the coarser and heavier extraneous matter without breaking the latter into smaller and finer particles, which would remain in the fiber being treated. Also, owing to the comparative slower speed of rotation of the beating roller 5, there would be less danger of fracture of the roller blades striking the heavier and coarser material.
After the treatment of the materials by the first burring mechanism, it is conveyed by thetrans- ..fer roller 3 from the crushing roller 4 to the crushing roller 4 of the second burring mechanism tobe treated by the beating roller 5' coacting with the roller 4'. As the heavier and coarser extraneous matter has been removed, the
rollers 4' and 5' aredriven at a higher speed than the rollers l and 5. This speedier drive of the rollers 4' and i in the second burring mecha nism is more efl'ective in the elimination of the lighter and finer particles oi extraneous matter than is the slower drive of the rollers in the first purring mechanism. After the treatment by the rollers 4' and 5', the material is'conveyed by the transfer roller 6 to the carding cylinder 2 for Y er, a crushing roller for receiving the mater al from the bristle roller, and a beating roller meeting with the crushing roller for removing extrane= ous matter from the material carried by the crushing roller; said burring mechanisms being arranged between the breasting roller and the card--- ing cylinder so that the bristle roller 0! the first mechanism coacts with the breasting roller and with the crushing roller 0! said first mechanism to convey the material from the breasting roller to said crushing roller, and the bristle roller of the second mechanism coacts with the crushing rollers of both mechanisms to convey the material from the preceding crushing roller to the succeeding crushing roller; 8. transfer roller for transmitting the material from the crushing roller of the second barring mechanism to the carding cylinder; the beating roller of the first hurting mechanism being positioned to contact with the associated crushing roller betwe n the bristle rollers of the respective barring mechanisms, and the beating roller 0! the second burring mechanism being positioned to contact with its associated crushin roller between the bristle roller of said second mechanism and the transfer roller; and means for driving the respective burring mechanism so the speed of the first mechanism is comparatively less than the speed of the second mechanism, whereby the slowly driven beating roller of the first mechanism operates to eject the larger and heavier particles of extraneous matter and-the more speedily driven beating roller of the second mechanism operates to eject the lighter particles of extraneous matter.
