Primary Examiner-Donald E. Watkins Attorney-Michael S. Striker [57] ABSTRACT A method of removing impurities from staple fibres in ringless spinning and a device for performing said method. The impurities are ejected immediately after being contacted by the combing roller into a withdrawing space by the effect of the acceleration imparted thereto by said contact. Spinning units including a fibre separating mechanism and a rotary underpressure spinning chamber are employed. The inlet or the guiding walls for said impurities are directed in view of the separating roller tangentially. The withdrawing space can be connected to the central sucking device of the machine.
9 Claims, 4 Drawing Figures CENTRAL METHOD OF REMOVING IMPURITIES AND SIMILAR MATTER FROM STAPLE FIBRES IN RINGLESS SPINNING AND DEVICE FOR PERFORMING SAID METHOD The object of the present invention is a method of removing impurities and similar matter from staple fibres in ringless spinning in spinning units including a fibre separating mechanism and a rotary underpressure spinning chamber, and a device for performing said method.
In ringless spinning are various impurities, as e.g., fragments of capsules, kernels, and leaves of cotton, fibre conglomerates and peelings of synthetic fibres are the frequent reson for yarn breakage and have an unfavorable effect on the quality of the spun yarn also by causing a filling of the collecting surface of spinning chambers, thus causing a change of the values of the spun yarn, whereupon arises the necessity of removing periodically the said impurities.
The indirect influence of these impurities in the fibre material to be processed in the spindeless spinning machines is hitherto avoided by demanding a higher degree of cleanliness of the presented sliver this being connected directly with higher expenses for the preparation of the fibre sliver. Even thus it is impossible to attain a particularly favourable state.
The present invention has the purpose to remove the said disadvantages and to establish a method of and a device for enabling the spinning of fibrous materials to be processed even when lower requirements are put on the material as to the content of impurities.
The subject matter of the method according to the present invention consists in that the impurities are ejected immediately after being contacted by the combing roller into a withdrawing space by the effect of the acceleration imparted thereto by said contact.
The subject matter of the device for performing said method consists in that the inlet into the withdrawing space is made in the wall of the hollow of the body of the fibre separating mechanism which is situated oppositely to the operating part of the combing (fibre separation) roller, in the section between the separating zone and the passage of the hollow into the exit channel. It is advanatgeous according to the present invention when the inlet is directed at least approximately tangentially in view of the fibre separating roller.
According to the present invention, at least approximately tangentially directed guiding surfaces can be arranged at the inlet, or said inlet can be constituted by channels arranged behind each other.
An embodiment is advantageous, in which the width of the inlet is equal at least to the width of the operating part of the fibre separating roller.
From the viewpoint of attendance, an embodiment is favourable, in which the withdrawing space is connected to the central sucking device of the machine.
Embodiments in form of example according to the present invention are diagrammatically shown in the accompanying drawings, of which FIG. 1 represents a section through the fibre separating mechanism;
FIG. 2 an embodiment with an inlet including guiding walls; a
FIG. 3 an embodiment of the inlet including channels;
FIG. 4 a view through the inlet as shown in FIG. 1, on the fibre separating roller.
The staple material 1 is fed by the feeding roller 2, and passes through the resilient condensing plate 3 to the fibre separating roller 4 which rotates at a high speed, the cylindrical operative part of said roller being provided with fibre separating tips 41. At the point of the strongest action of the fibre: separating roller 4 upon the fibres of sliver 1, i.e., in the so called fibre separating zone 5, separation of fibres from the sliver 1 takes place. The said fibers combed out from the sliver l are brought into the exit channel 6 which debouches on the sliding wall of a not shown, known spinning chamber, in which said fibres are transformed into yarn, all this being generally known.
In the zone between the fibre separating zone 5 and the passage 711 of the hollow 71 of body 7, in which the separating roller 4 is arranged, an inlet 8 is provided in wall 712 into the withdrawing space 81, at a position opposite to the operative part of the fibre separating roller 4.
This inlet 8 has advantageously an at least approximate tangential course in view of the separating roller 4.
In the embodiment as shown in FIG. 2, tangentially arranged guiding walls 82 are mounted in the inlet 8.
In the embodiment as shown in FIG. 3, the inlet is constituted by channels 83 arranged mutually beside each other.
It is advantageously when the width of the inlet 8 is at least equal to the width of the operative part of the separating roller 4 as can be seen in FIG. 4.
The withdrawing space 81 can be emptied periodi' cally or can be advantageously connected to the diagrammatically illustrated central sucking device of the machine (see FIG. 1).
Immediately after being contacted by the separating roller 4, the impurities as given above, which have a heavier mass than the fibres to be spun, are ejected upon action of the centrifugal force exerted by the separating roller 4 into the inlet 8, through which they are brought into the withdrawing space 81, from which they are removed either periodically or continuously by the central sucking device. Together with the mentioned impurities, also too short fibres can be removed in such manner, which would be useless as a part of the yarn to be spun.
