Definitions
- the invention relates to a fixed comb for a combing machine comprising at least one row of punched needles, which are arranged parallel to one another and are enclosed between two cover plates, with the free needle board being recessed, compressed air between the cover plates and two adjacent needles. Channels are formed.
- a fixed comb for a combing machine comprising at least one row of punched needles, which are arranged parallel to one another and are enclosed between two cover plates, with the free needle board being recessed, compressed air between the cover plates and two adjacent needles. Channels are formed.
- a fixed comb is known from EP 0 351 443 CI.
- the object of the invention is to further increase the effectiveness of the cleaning action in such a pneumatically cleaned fixed comb.
- the needles have impressions, so that the overlapping impressions of adjacent needles form an air channel, the impressions tapering in width towards the exit region.
- This tapering and thus a reduction in cross-section results in an increase in the flow velocity of the exiting air stream, so that it can be used even more effectively for cleaning.
- the air flow can be directed even more specifically to those parts of the free needle board where dirt is particularly deposited.
- At least one cover plate in the outlet area has a free board and is bent inwards to form an air guiding area. This supports the targeted guidance of the air flow.
- the impressions in the needles extend into the area of the free needle board. In this way, a certain guidance of the air flow is still achieved even after leaving the area covered by the cover plates.
- the cover plates advantageously protrude above the needles on their upper side, and an air supply duct and / or an air distributor duct is formed in this area by deep-drawing the cover plates.
- an air supply duct and / or an air distributor duct is formed in this area by deep-drawing the cover plates.
- an airflow divider is formed in the air duct. This creates two partial air streams, which can be directed in a targeted manner, for example, towards the front edge and the rear edge of the needle.
- Fig. 1 to 3 different embodiments for the configuration of the air channels on a fixed comb according to the invention.
- a fixed comb shown in FIG. 1 consists of a row of needles 1 arranged next to one another, which are covered by a front and rear cover plate 3 or 4 in relation to the direction of movement (arrow 2) of the sliver.
- the front cover plate 3 has on its upper side projecting beyond the needles 1 a bulge 5 which is produced by deep drawing and which, together with the projecting part 6 of the rear cover plate 4, forms an air distribution channel 7.
- the needles 1 are tapered and sharpened in the area of their free needle board 8 by embossing.
- An air guiding channel 9 is also formed by stamping, which is limited on the one hand by the front cover plate 3 and on the other hand by the non-stamped sections 10 of two adjacent needles 1.
- the air channel 9 tapers towards the outlet opening 11, as a result of which the air flow accelerated and directed towards the front edge 12 of the needle 1 as seen in the combing direction.
- FIG. 2 shows a needle 1 'in which the air duct 9' is delimited by two non-embossed areas 10 '.
- Fig. 3 shows a needle 1 ", in which the air duct 9" is delimited by two non-embossed areas 10 ", but there is also an air flow divider 13 formed by a non-embossed section through which the air flow in Air duct 9 "divided and two separate outlet openings 11" is supplied.
- cover plates are not shown in the exemplary embodiments according to FIGS. 2 and 3.
- the front cover plate 3 it can be provided that it has a free board 14, which can be bent inwards with respect to the illustration in FIG - Board 8 is directed.
