Definitions
- the invention relates to a fixed comb for a comber comprising a Fixkammarme for fixing a Fixkammgarnitur, a holding section, and a stiffening.
- Fix combs are elements that hold the short fibers in the tongs Faserbart in the combing process. Conversely, the fixed comb prevents the short fibers from being caught by the tear-off rollers together with the longer fibers. To do this, the fix comb must be positioned between the clamping pliers and the tear-off rollers. But just this space, or better the distance between tear-off rollers and lower tongs, is technologically of great importance. He is also called Ecartment. With a shorter average length of the cotton fibers to be processed and the Ecartment is set small. The ridge should therefore, if possible, have a very small extent in the material flow direction in order not to restrict the technological setting values of the machine.
- the fix comb must be arranged as close to the tear-off rollers. Since a dynamic load additionally acts on the ridge comb, which causes a deflection transversely to the longitudinal direction of the ridge comb, a ridge with too low rigidity can collide with the rip-off rollers.
- a high rigidity often has the disadvantage of high inertia, which requires more power at more than 500 combs per minute.
- today's modern fixed combs are made from a simple sheet of rectangular extruded aluminum section, which are relatively inexpensive and offer a good balance between lower mass and high rigidity. These Fixed combs are fully suitable for comb games up to 450 per minute.
- a carrier for a fixed comb which has a stiffening element, which is integrally connected to the holding portion and the support plate.
- the stiffening element is designed as a hollow profile.
- the object of the present invention is to provide a very light and stiff fixed comb, which is inexpensive to produce and comprises only a few parts.
- the invention solves the problem set by the teaching of claim 1. Further advantageous design features of the invention are characterized by the subclaims.
- the fixed comb for a combing machine comprises a Fixkammarme for fixing a Fixkammgarnitur, a holding section, and a stiffening.
- the Fixkammgarnitur is permanently connected by means of a fastening with the stiffener.
- the stiffening acts directly on the Fixkammgarnitur, whereby a deflection of the Fixkammgarnitur is avoided.
- the distance to the tear-off rollers is thus smaller adjustable.
- the attachment connects the Fixkammgarnitur uninterrupted across its width with the stiffener.
- the compound for fixing the Fixkammgarnitur is formed on the stiffener as an adhesive bond or as a forming process.
- the fixed trim can be configured and connected to the stiffener.
- a further increase of the moment of resistance results when the holding portion is connected to the Fixkammexcellent, and the holding portion is supported on the stiffener.
- the Fixkammgarnitur between the stiffener and the Fixkammja is arranged and fastened.
- FIG. 1 shows a section through a Fixkamm according to the invention according to a first embodiment.
- 2 shows a section through a fix comb according to the invention according to a second embodiment;
- Fig. 3 shows a section through a Fixkamm according to the invention according to a third embodiment.
- Figure 1 shows a fixed comb 1 according to a first embodiment in a sectional view.
- the fixed comb 1 extends in its length at least over the width of a combing segment on a combing machine, not shown.
- Today's combing machines usually have 8 jobs, in each of which a lap roll with a width of about 300 mm is combed.
- the Fixkammlust 5 has a longitudinal extent, which goes beyond the width of the lap roll, whereas against the Fixkammgarnitur 2 has an approximately identical length or slightly greater length, which corresponds to the width of the lap roll.
- the fixed comb 1 comprises a Fixkammwhere 5, at the lower region of a Fixkammgarnitur 2 is arranged undetachably.
- the Fixkammparticularly 5 has a flat portion which is integrally connected in the upper region with a holding portion 8 to which the fixed comb 1 can be fastened within the comber.
- the holding portion 8 is at least partially formed in this embodiment as a circular ring portion which is fastened by means of elastic deformation of a rod-like attachment or by a spring element on the tong plate of the comber.
- a separate stiffener 7 is connected without connecting elements with the Fixkammexcellent 5.
- the Stiffener 7 comprises in this embodiment, a first planar vertical leg 7a, which is connected to the Fixkammango 5 by means of a permanent attachment 9, which is designed as an adhesive connection.
- a leg 7b connects in the horizontal extent, on which the holding portion 8 is supported, so that the connection of stiffener 7 and 5 Fixkamm uman gets to the holding portion 8 a high stability.
- the holding portion 8 may be connected to the leg 7b by means of permanent attachment 9.
- a second vertical leg 7e is arranged, which clamps the Fixkammgarnitur 2 together with the flat portion of the Fixkammismes 5.
- Both the Fixkammarme 5 as well as the second vertical leg 7e are connected by means of permanent attachment 9, which may be configured as an adhesive bond, with the Fixkammgarnitur 2.
- the stiffener 7 is thus connected directly or indirectly to the fixed comb carrier 5 and the holding section 8 at three points.
- the ribs 7c and 7d connect the leg 7b with the second vertical leg 7e, which results in a very light hollow profile of two parts with a very high stability by means of permanent connection, to which the Fixkammgarnitur 2 is permanently attached.
- the Fixkammgarnitur 2 may consist of juxtaposed needles, in particular the attachment by means of a double-sided thin adhesive tape to the Fixkammango 5 and the second vertical leg 7e is a very efficient and easy mounting, which makes the use of fasteners such as screws and clamp superfluous.
- the juxtaposed needles can be inserted directly into the fix comb 1 via the adhesive tape.
- the Fixkammgarnitur 2 can be fixed by means of liquid adhesive between the stiffener 7 and the Fixkammexcellent 5.
- the fixed comb carrier 5 with the holding section 8 and the stiffening 7 can be made of a high strength aluminum alloy or a fiber reinforced plastic.
- the stiffening 7 is arranged on the Fixkammango 5 in the material flow direction, wherein the stiffener 7 has the largest horizontal extent in the upper area near the holding portion 8 in order to realize the smallest possible distance between the Fixkammgarnitur 2 and the Abr contemplatwalzen not shown.
- the stiffening 7 shown in this embodiment extends substantially without interruption along the entire length of the fixed comb 1, but at least over the length of the Fixkammgarnitur 2. With the stiffener 7, both the bending stiffness of the Fixkamm umans 5 and the Fixkammgarnitur 2 is significantly increased since due to the dynamic movement of the fixed comb 1, in particular elastically deflects in the middle, whereby the distance of the Fixkammgarnitur 2 decreases to Abr alonewalze.
- the fixed comb carrier 5 with the holding portion 8 and the stiffening 7 is made in one piece as a hollow profile.
- the essential difference from the embodiment of Figure 1 lies in the attachment 9 of the Fixkammgarnitur 2, which is partially disposed within a receptacle 6 of the Fixkammmiks 5 and connected to the side walls of the receptacle 6 by means of forming process.
- the forming process may be a rolling process, in which at least the side walls of the receptacle 6 are plastically deformed and are thereby permanently connected to the Fixkammgarnitur 2.
- a burnishing can be made by a stamping, stamping or other forming a permanent permanent connection between the Fixkammango 5 and the Fixkammgarnitur 2, which preferably takes place without interruption over the entire length of the Fixkammgarnitur 2.
- this attachment 9 requires no further connecting elements, whereby the fixed comb 1 is very easy. Furthermore, there is no relative movement between the Fixkammango 5 and the Fixkammgarnitur 2.
- the attachment 9 by forming process can be used in all three embodiments.
- the bending stiffness receives the fixed comb 1 in the embodiment of Figure 2 also by the stiffener 7, which is connected as a substantially triangular arrangement of a leg 7b and a rib 7d with the holding section 8 and the Fixkammanii 5 and the increased moment of resistance directly to the Fixkammgarnitur second acts.
- the stiffener 7 which is connected as a substantially triangular arrangement of a leg 7b and a rib 7d with the holding section 8 and the Fixkammexcellent 5 and the increased moment of resistance directly to the Fixkammgarnitur second acts.
- a one-piece design is shown, wherein the two-part embodiment of Figure 1 is possible in which at least one leg 7a is permanently connected to the Fixkammexcellent 5 and the permanent connection between a second leg 7e, the Fixkammgarnitur second and the fixed comb carrier 5 can be produced by a forming process.
- the rib 7d ends in the area in which the Fixkammgarnitur 2 is arranged in the receptacle 6.
- the rib 7d is integrally in the region of the receptacle 6 in the Fixkammexcellent 5, whereby the bending stiffness of the Fixkammgarnitur 2 is increased.
- the stiffener 7 is similar to that formed in Figure 1. Instead of the Fixkammisme 5 but the stiffening 7 is fixed with a first vertical leg 7a to a plate 4 by means of adhesive bonding.
- a second vertical leg 7e is designed to at least partially clamp the fixed comb garnish 2 with a lower region of the plate 4.
- the attachment 9 between the second vertical leg 7e, the Fixkammgarnitur 2 and the lower portion of the plate 4 can be done by means of adhesive bonding or by a forming process. It is insoluble over the length of the Fixkammgarnitur and preferably uninterrupted, so that here, too, no relative movement between the components can arise.
