Definitions

• the invention is directed to a fixed comb and a fixed comb holder for a textile combing machine, the fixed comb having a fixed comb plate, on the base of which a pinstrip can be fastened, with a holding section being formed on the upper side of the basic body, over which the fixed comb is held by means of a holding clip the fixed comb holder can be fixed on this.
• a fixed comb of a textile combing machine carries out an approximately elliptical movement and is thereby and due to its engagement in the sliver to be combed exposed to constantly changing acceleration forces, which due to the dead weight of the fixed comb results in a high mechanical load of the same and the assembly laughing the fixed comb leads in the fixed comb holder.
• This problem is becoming more serious because the cycle times of modern Kämm machines are constantly increasing.
• the object of the invention is to design a fixed comb or a fixed comb holder of the type mentioned at the beginning in such a way that wear is drastically reduced while maintaining the possibility of simple and quick fixing of the fixed comb.
• This object is achieved according to the invention in that wear protection, in particular a plastic with good setting ability and good surface sliding properties, is provided in the contact area between the fixed comb and fixed comb holder.
• wear protection in particular a plastic with good setting ability and good surface sliding properties
• a metal with corresponding properties can also be used.
• the holding section of the fixed comb plate of the fixed comb consists entirely of a plastic.
• thermoplastic polyurethane can be used as the plastic, which is in the hardness range from approx. 80 to approx. 100 Shore A or 30 to 80 Shore D.
• Such a product has the advantage of possessing vibration, impact and shock-absorbing properties in addition to excellent wear values.
• the holding section of the fixed comb plate consists of plastic, this can be designed as a profile with a foot, so that it can be fastened to the fixed comb plate via a type of welt groove.
• the plastic can also be designed as a coating of the fixed comb and / or the fixed comb holder, in particular the holding clip.
• the fixed comb is provided with a plastic coating in the region of the holding section.
• the inside of the retaining clip can also be provided with a plastic coating.
• the base body of the fixed comb plate and / or the contact area on the fixed comb holder can also be provided with a plastic coating.
• the plastic is produced on the basis of a pure, ultra-high-molecular low-pressure polyethylene as a press-sintered plastic.
• a pure, ultra-high-molecular low-pressure polyethylene as a press-sintered plastic.
• Such a plastic is highly wear-resistant, has a low sliding friction coefficient, is noise-reducing and chemical-resistant.
• An additional or alternative way of reducing the wear described at the outset is to produce the fixed comb in a lightweight construction, in particular from composite materials and / or light materials such as magnesium.
• the invention also relates to a fixed comb holder for a textile combing machine with a holding area for a fixed comb plate and a pivotably mounted holding clip for gripping over the holding section of the fixed comb plate, it being provided according to the invention that the inside of the holding clip and / or the holding area with a plastic - Coating is provided.
• the plastics mentioned above are particularly suitable. The invention is explained in more detail below on the basis of a preferred exemplary embodiment in conjunction with the drawing. Show:
• FIG. 1 is a view of the mounting area of a conventional fixed comb according to the prior art
• FIG. 3 is an enlarged view of detail III in FIG. 2,
• FIG. 4 is a side view of a conventional fixed comb holder of a combing machine
• FIG. 5 and FIG. 6 a section through a first embodiment according to the invention with the holding clip open or closed
• FIG. 7 and FIG. 8 a section through a second embodiment according to the invention with the holding clip open or closed
• FIG. 11 shows a section through the fixed comb holder according to the many embodiments
• 12 shows a section through a fixed comb plate according to FIG. 10 inserted into a fixed comb holder according to FIG. 11,
• FIG. 14 shows a partially broken away representation of the embodiment according to FIG. 13 from a viewing angle offset by 90 °.
• FIG. 1 shows a fixed comb 1 according to the prior art, which comprises a fixed comb plate 2, on which a pinstripe 3 comprises a row of needles 5 bordered between two cover plates 4.
• a holding section 6 is formed with an approximately ⁇ -circular curved surface.
• this holding section 6 is overlapped by a holding clip 9 pivotably mounted about an axis 8, a bend 10 engaging at the end of the holding clip 9 over the inner edge 11 of the holding section 6. This is shown in more detail in detail III in FIGS. 2 and 3.
• thermoplastic polyurethane is provided according to the invention.
• the inside of the holding clip 9 is provided with a plastic coating 14.
• the plastic coating 14 is applied to the upper side of the holding section 6.
• the entire fixed comb plate 2, i.e. both the base body 18 and the holding section 6 are provided with a plastic coating 14.
• the holding section 6 is provided with a plastic coating 14, as is the holding area 15 of the pinstrip holder 7.
• the holding section 6 of the fixed comb plate 2 is not formed in one piece with the base body, but rather as a plastic block 14 which has a foot 16.
• thermoplastic urethane can be used as the plastic, or preferably a plastic based on a pure, ultra-high-molecular low-pressure polyethylene in the form of a press-sintered plastic.
• the fixed comb plate can also be made entirely of plastic. It can be realized with reinforcements as a composite part or without reinforcement with a load-optimized geometry.
