Definitions

  • the invention relates to the carding of textile fibers (but in particular not exclusively “short staple fibers", with a maximum fiber length of up to approx. 60 mm).
  • the modern card includes a so-called drum (also called “Tamour”) or two drums of larger dimensions.
  • This (each) drum works with a cover arrangement together to perform the actual carding.
  • the drum or the pair of drums
  • the feeding system usually processes fibers in the form of a Cotton wool.
  • the take-off system is usually designed to form a band.
  • Each "working element” drum, licker-in, pick-up, lid) is equipped with a so-called Provide a set that takes over the actual processing of the fibers.
  • the feeding system is for the most uniform feeding possible the drum with fibers to be processed over the entire working width of the working elements to shape, i.e. all over for processing fibers with trimmings provided width.
  • the acceptance system is for collecting as evenly as possible of processed fibers designed across this entire width.
  • the drum is the "heart" of the machine and exerts a significant influence on all functions.
  • the fiber flow is only at the drum dissolved up to individual fibers and cleaned thoroughly.
  • the cleaning is done by excretion of unwanted materials from the transport route through the working gap is defined on the circumference of the drum.
  • Include "unwanted” materials e.g. Dust, dirt particles, nonsoluble nits, and short fibers (non-spinnable Flight).
  • the "selectivity" of the elimination process is of crucial importance Significance - the "desired" material (the good fibers) must as far as possible for the time being forwarded in the working gap and then to form the band to the downstream one Work item are given.
  • Today's conventional card has a drum with a diameter of approx. 1000 up to approx. 1300 mm.
  • the working width is approx. 1000 mm.
  • a new type of card is in EP-A-446 796. According to the latter proposal, the Restrict the drum diameter (or its working surface) in such a way that it does not exceed 800 mm and preferably between 350 and 450 mm lies.
  • This drum should still work directly with the feed and take-off system, that is, the card contained only a single drum.
  • the card was preferably formed as a revolving card. All that affect the working gap Parts (e.g.
  • EP-A-446 796 made of a material with a high modulus of elasticity for reduction of deflections over the working width.
  • EP-A-446 796 are both steel and fiber reinforced plastic have been given as examples.
  • the card is now preferably driven at a relatively high speed to achieve a higher peripheral speed than previously used. It is thus possible to improve the selectivity of the separation process. Also is there is a constant requirement on the card designer, the precision of the elements, which form the working columns. Achieving higher precision causes additional costs already in the manufacture of the individual elements, e.g. for machining a cast part because of the required tolerances when casting cannot be met. The problem is also complicated by that the rotating parts are deformed due to centrifugal forces but also because of Are subject to thermal expansion. The deformation problem increases in one non-linear relationship to speed. Attention must also be paid to higher speeds that no vibrations of the working elements or their carriers are excited, that could significantly influence the gap width. Concentricity errors can occur in play a significant role in this context.
  • the drum of a conventional card is made of steel or cast iron. It is undoubtedly possible to meet the increasing demands with these materials too fulfill. Meeting the increasing demands with conventional materials leads to rapidly increasing manufacturing costs, especially for reworking (e.g. Grinding or even machining) after the production of a blank.
  • the present invention is a first invention.
  • the present invention is based on the knowledge that it is possible to use the use of fiber-reinforced plastic to create a body which can be used practically without reworking in the bore as a roller (eg drum or pick-up) of a card and which can nevertheless meet the highest requirements , If, however, it is considered that "fiber-reinforced plastic" is a composite of, for example, glass fiber and a resin, that the modulus of elasticity of, for example, glass silk is more than 70,000 N / mm 2 , whereas that of a polyester resin is only approx.
  • the reinforcing fibers can be in the form of "endless” filaments and / or staple fibers of different stack lengths and / or in the form of a "fabric” (eg a fabric), and that the most varied manufacturing processes (eg injection molding or injection molding of a staple fiber / Resin mixture) for the production of parts made of fiber-reinforced plastic, it becomes clear that the use of "fiber-reinforced plastic" does not easily lead to the goal.
  • the reinforcing fibers should therefore be arranged selectively in order to achieve a targeted To achieve the performance of the end product, especially to Meet predetermined minimum requirements for selected product properties. The selection of properties for which minimal requirements are made is therefore of great importance.
  • the reinforcing fibers can be in one Carding roller made of fiber-reinforced material in the shape of itself in the circumferential direction extending structure to be present.
  • the arrangement can be made that the carding roller within a predetermined speed range Diameter increase of less than 10, preferably less than 5 hundredths of a millimeter experiences.
  • the reinforcing fibers can be made from “continuous filaments” (e.g. from “glass silk roving”) exist, but could be used in the form of a mat or fabric.
  • Important to achieve the required resistance to deformation (Extension of the diameter) under the centrifugal forces is the orientation of the reinforcing fibers in the final product.
  • the product geometry (especially the wall thickness), and the type of fiber (the type of fiber) and the proportion of fiber (the amount or content reinforcing fibers) in the composite material also play a role here, as well the possible use of fillers and modifiers.
  • glass fibers preferably a glass content greater than 50% is selected.
  • the matrix material (Binder) must still be able to the composite to give the necessary cohesion, even under deformation or under Tension.
  • a glass content of approx. 50% to 70% should be given an acceptable wall thickness ensure a sufficient modulus of elasticity.
  • the matrix material must have a certain toughness, especially with regard to deformation cycles (repeated deformation followed each time by returning to the Initial state). It is particularly important to note that the deformations can also be caused by thermal expansion, with the resin the foreseeable temperature changes must not become soft or brittle. On Thermoset (e.g. a polyester or an epoxy resin) can be used Thermoplastic, however, is not.
  • the predetermined composite is preferred (or its components become) processed to give a substantially tubular body which can be assembled with other elements, but not essential Rework required for use as a carding roller.
  • This body can be axial Have a length between 800 mm and 1.2 m.
  • the outside diameter is preferably 900 to 1100 mm.
  • the wall thickness is preferably in the range 10 to 30 mm (e.g. 15 to 20 mm.) and it is preferably along the length of the body roughly constant.
  • Such a body can be formed by means of a winding process be what a very low unbalance or a very low concentricity error results without requiring the aforementioned rework.
  • the mass of a body according to this invention will be considerably lower than the mass of a corresponding body made of a conventional material, due to the relatively low density of the composite material compared to steel or cast iron.
  • the density of the composite material can be, for example, approximately 1.4 gm / cm 3 . This results in considerable advantages with regard to the moment of inertia (acceleration resistance), ramp-up and ramp-down times and the required drive power.
  • the tubular body preferably has a constant outside diameter the length, i.e. this body (unlike a pressure vessel) is not radially behind end sections running on the inside.
  • the end parts of the body are therefore preferably connected to supports (drum bases), each drum base having one Can have hub, spoke and a rim portion.
  • the rim part is with the Composite body joined, e.g. using an adhesive while the Hubs take up a carrier or drive shaft.
  • the end faces of the body could e.g. by cutting a (somewhat) longer body. In the preferred solution are the end faces of the body simultaneously with the Main part of the body is formed.
  • the outer cylindrical surface In order to form a ready-to-use carding roll, the outer cylindrical surface must be the body with a set, what in a conventional card by pulling a "wire".
  • the same procedure for attaching the The set can also be used for a carding roller (in particular a drum) according to the invention are used, preferably at a predetermined operating speed the pressure generated in the composite material by the mounting process and the largely compensate for the tensile stress generated by centrifugal force in the same material. This helps to achieve a condition in which those generated in the composite Stresses are always below the fatigue strength of the material.
  • the Rigidity of the roller bottoms is preferably the rigidity of the tubular body adjusted so that the roller is as even as possible under the influence of centrifugal forces over the entire length (and in any case over the working width) or around deformed the entire circumference.
  • the rigidity of a roller base for a roller fiber-reinforced plastic should therefore be compared to that of a drum base can be reduced for a cast or steel roller. It must be ensured that that the roller bottoms have no inherent (vibration) resonance within of the intended operating speed range could be excited.
  • FIG. 1 The arrangement according to FIG. 1 is only given as an example. The ones to be described Features can also be used in other card types and in cards even in the large machines used to manufacture nonwovens (Nonwovens) are suitable.
