Definitions
- the invention relates to a combing machine according to the preamble of the main claim.
- the combers used in practice today usually have eight side by side arranged combing heads, which in each case a cotton roll is presented for combing out.
- the combed from the individual combing heads and discharged nonwoven fabric is summarized by means of known devices into a sliver and fed transversely to the material flow direction of the combing head on a guide table a subsequent drafting unit.
- the sliver formed at the drafting device is then placed in a loop in a can through a funnel wheel in a can.
- Such combing machines work today with Kammspiellibrary of up to 600 KS / min.
- combers have a gear unit, a longitudinal part with juxtaposed combing heads and a drafting unit with subsequent tape storage.
- the longitudinal part knows a machine frame, which consists of a solid bottom plate, on which massive side plates are attached. Between the side plates, which are also provided with bearings for the longitudinal shafts, the individual units of the combing heads are attached.
- the present invention seeks to propose a device for the extraction of the combed components (noils etc.) and for the application of a negative pressure to a web-forming device, which on the one hand takes into account different vacuum conditions required and on the other hand good accessibility Ensures combing units and suction devices.
- the respective intake pipes of the nonwoven fabric forming means of Kämmaggregate open into a common suction channel, which is in communication with the first vacuum source, wherein the suction channel and the collecting channel side by side and in the longitudinal direction of the longitudinal member and mounted below the combing units are.
- suction pipes made of plastic can be made by blow molding.
- Suction pipes can be produced with this known method, which have no inner seam, on which fibers could accumulate, which in turn can lead to blockages in the pipes.

- the term "combing unit” is to be understood as an apparatus for combing out a pulp with subsequent banding of the combed pulp.
- such a device consists of the following individual components, such as a nipper unit, combing cylinder (round comb), ridge comb, tear-off cylinder or a rip-off roller cooperating with the combing cylinder (Heilmann principle) with a subsequent soldering device (eg a screening drum) and a nonwoven assembly banding.
- a combing unit is shown, which works according to the Heilmann principle.
- the individual suction channels 17a are connected to a channel 21, in which a combing cylinder 11 and a brush roller 13 are rotatably mounted.
- the brush roller is provided for cleaning the combing segment of the combing cylinder.
- a tuft protruding from the closed pliers 10 is combed out, as shown in the enlarged view Figure 3 can be seen.
- the combed out components enter a channel 21 and are transferred under the action of a negative pressure in the suction channel 17a, the other end opens into the collecting channel 17, via the collecting channel 17, via the connecting channel 31 with a second negative pressure source P2 is in connection, the extracted components are supplied to a central disposal facility 30, for example.

These longitudinal shafts are driven by drive elements, which are located in the drive unit A.

- the frame 4 is pivotally mounted about not shown means to a mounted on the frame signs RS axis 6.
- the frame 4 may be pivotally mounted directly on the tong plate 2.
- the fiber tuft projecting beyond the clamping point is combed out by a combing segment of a combing cylinder 11.

- the individual fitting teeth can be made of stamped tooth sets. However, if a larger number of teeth Zahniturzähnen per cm is required, it is necessary to produce the individual fitting teeth with a very small thickness. It must be ensured that, despite the small tooth thickness, the exact contour of the external tooth form is ensured during manufacture. To produce such sets of teeth, the production of the individual fitting teeth is proposed by the photolithography method.

- Service work eg cleaning work
- the suction channels 17a can be arranged approximately in the vertical direction.
- the outflow in the channels 21 (noils, nits, dirt, etc.) can be transferred directly and without loss to the subsequent collection channel 17, from which it is transferred via the channel 31 to a central collection point 30 under the influence of the vacuum source P2 ,
- the negative pressure generated by the negative pressure source for example at the level of 900 Pa (Pascal)
- one or more compressed air sensors 40 are mounted within the suction channel 19, which are connected via lines 42 to a control unit ST in connection.
- the control unit ST is connected to a controller 44, which controls the vacuum source P1. If a predetermined negative pressure is exceeded or fallen below, this is measured by the sensors 40 and transmitted to the control unit ST. Via the control unit ST, a control command is transmitted to the controller 44 in accordance with the signal from the sensor 40, which controls the vacuum source P1 accordingly until the sensors 40 again signal a predetermined desired value.
- connection channel 46 is provided to a connecting channel 31 which is mounted between the collecting channel 17 and the second negative pressure source P2 (about 150 Pa).
- a one-way locking member 48 is provided in the connecting channel 46. This blocking member 48 allows in the channel 46 only an air flow in the direction of the vacuum source P2, as indicated by an arrow.
