(Cl. 57-5831) The present invention relates to a device for simultaneously dividing a fibrous material into fibres and conveying of the separated fibres to the spinning mechanism, particularly for spindleless spinning machines.
Various types of such spindleless spinning machines are known, for spinning the yarn directly from loose fibres, the spinning mechanism of such machines comprising for example a spinning basket provided with needles or a stripping member. These known types of spinning machines have one common disadvantage in that they have to be provided with a separate mechanism for tearing the fibres from the supplied material (band or roving) as well as with a further mechanism for conveying the separated fibres into the twisting mechanism. For these reasons the machine becomes intricate and diflicult to operate and the consumption of driving power is increased.
According to the present invention the entire mechanism is substantially simplified, as it unites both mechanisms into one, which serves on the one hand for tearing the fibres from the supplied fibrous fabric (roving, band) and on the other hand for conveying the separated fibres to the spinning mechanism, for example a spinning basket.
According to the main feature of the invention a rotary fan of the vane-type is provided between the supply of the fibrous material and the spinning device, the vanes of said fan being provided also with combs separating the supplied fibrous material into individual fibres, which are conveyed by the air stream from the fan to the spinning mechanism.
The combs of the fan can be of the toothor needletype.
The accompanying drawing shows:
Further features and advantages of the invention will be apparent from the ensuing description on hand of the accompanying drawing representing an exemplary embodiment of the invention.
FIG. 1 is a diagrammatic representation of the spinning device,
FIG. 2 shows a toothed comb of the fan vanes,
FIG. 3 a needle comb of the fan vanes.
The treated fibrous material 1 (roving, band or the like) is supplied by means of feed rollers or supply means 2, 3 to a blower which comprises a casing 4 and a fan 5 of the vane type in such a way that combs 6 secured to the ends of the fan vanes are adapted to strip the individual fibres 7 from the fringe 8, whereby the fibrous material is divided into fibres and the separated fibres are conveyed by a stream of air from the fan through a discharge conduit 9 to a known spindleless spinning device, such as a spinning basket 10 of the needle-type.
Similarly, the fibres retained by the combs 6 of the fan 5 are taken off the combs by the air fiowing under the influence of centrifugal force and are conveyed to 3,127,730 Patented Apr. 7, 1964 the discharge conduit 9. The separated fibres, supplied by the air current, are condensed and twisted into yarn or roving by the spindleless spinning device, such as the spinning basket 10 of the needle type.
The yarn or roving 11 is then wound in the conventional ways on a known bobbin 12.
The combs 6 provided on the vanes can be equipped with pointed projecting means spaced from each other in the direction of the axis of rotation of the rotary fan means 5. Either teeth 13 (FIG. 2) or needles 14 (FIG. 3) may be provided.
By the arrangement according to the invention the Whole working mechanism of the spindleless spinning device is greatly simplified and is extremely eflicient in operation.
