Definitions

  • the invention relates to a roller according to the preamble of the claim 1 and a device equipped therewith according to the preamble de Claim 18.
  • Such a roller is known as a brush roller from the book "Internationales Lexicon textile finishing + border areas "by C.-H. Fischer-Obsien, A. Laumannsche Verlagbuchmaschine Dülmen (1975), page 263 known for straightening the fibers from the surface of the goods.
  • brush rollers have fibers that are relatively hard and resilient. This high hardness is not suitable for all cases of erection treatment.
  • the brush roller also forms a rather unyielding cylindrical one Body that easily becomes uneven across the width of the web Treatment effect results when the web is not evenly on the brush roller is present, e.g. B. is somewhat wavy.
  • US Pat. No. 3,102,320 describes a device for straightening fibers fibrous textile fabric known, in which the roller body with brush-like densely packed tufts of equally long stiff nylon bristles that attack the fibers of the tissue surface and this stand up when the roller body rotates. To improve the effect have the tufts in a force-free state in one to the roller axis vertical plane a slight bend in the direction of rotation.
  • the invention is based on the object of a generic roller or to create a device equipped with it, which has an effective, gentle and as even as possible across the width of the web Bring about treatment effect.
  • the material of the elements according to the invention should have a certain softness, because of the enlarged cross-section nevertheless a sustainable attack on the Enable web surface. This succeeds because not individual unconnected and not to transfer shear forces to neighboring areas capable bristles or threads are present, but the entire Material of an element compact, i.e. is available in one piece.
  • One for this Aiming suitable material is through a polymeric material with a hardness from about 55 to 75 Shore A.
  • the bending stiffness of the elements is such that the in Axle height of the roller body existing elements when not rotating Roller, if they are only under the influence of the gravitational pull a substantially horizontal diameter of six to eight millimeters Maintain alignment, so do not drop limply.
  • the Operating speed of the roller body also has a centrifugal force.
  • the length of the flexible elements should be about 3 to 12 mm, preferably 7 to 9 mm (claim 3). So it's about for the elements around rather thinner fingers that are not quite as thick as usual human fingers.
  • the cross-sectional dimension should serve as an extension be understood in the axial direction of the roller; at in cross section circular elements this is the diameter of the elements, for rectangular ones Elements the width, seen in the axial direction of the roller.
  • Elements that are adjacent to one another in the longitudinal direction of the roller point in the latter Direction a small distance from each other, which is about 1 to 10 mm should be of the same order of magnitude as the extension of the flexible elements in the axial direction or rather less.
  • the distance should not to be too large, so that there is no interruption of the effect the flexible elements are given; on the other hand, they need one certain lateral clearance so that they can attack the web and the associated bending when the roller rotates not hinder each other.
  • the length of the elements can be about 30 to 150 mm (claim 4), preferably 60 to 80 mm (claim 5). To the optimal properties To achieve the flexible elements, a vote must be taken in individual cases between cross section and length.
  • the edge runs perpendicular to the web this and scrapes or squeegees the pole of a pile with increasing at first and then decreasing force high, giving a range of attack, which exceeds the range of individual pile threads, so that only a small one Interaction with the rotation of the individual pile threads occurs.
  • the elements on their front when rotating Side be flat, so that when you slip over the web surface act like a tongue and its alignment effect for the Pole with broad and emphatic frictional attack given by the tongue is.
  • the design according to claim 8 also serves to form the flexible Elements with a working edge running in the longitudinal direction of the roll, which in Moment of attack on the surface of the web acts like a squeegee edge.
  • the elements can in particular be rectangular or square Have cross-section with an axially parallel side (claim 9). Especially in in the latter case, the elements act like a kind on the web surface especially flexible squeegees.
  • the elements in several over the scope distributed axially parallel or helical rows.
  • the spaces between the elements in Circumferential direction of adjacent rows in the axial direction of the roller against each other be offset in order to be uniform over the width of the web To achieve attack on the same.
  • the offset can also be achieved, for example, according to claim 12.
  • roller body should not be continuous over the entire circumference be filled with elements, so that the result is a dense with elements occupied roller with a cylindrical envelope surface would result, but it are supposed to be separate groups of elements, each with a squeegee effect be present, each in the embodiment according to claim 14 act independently of the neighboring elements.
  • the roller according to the invention is in the embodiment described so far, where the elements extend in planes perpendicular to the roll axis, primarily for straightening and leveling the pole a pile and intended for lint removal.
  • the area of application however, it is not limited to this.
  • the roller can also be used for flat fabrics are used, in particular in the embodiment according to claim 15. Such a roller has a pronounced spreading effect, who either alone or together with other effects of Roller can be aimed.
  • the elements should not be limp, but also not wire-like.
  • the One can compromise between these alternatives provide that the bending stiffness of the elements is such that the Elements in a state free from external forces just maintained essentially. That means the elements be self-supporting to a certain extent and with the horizontal orientation of the the part adjacent to the roller body should not hang limply. However, the bending stiffness should also not be significantly above that for maintaining the necessary horizontal alignment. It should also be allowed that the centrifugal force on the horizontal alignment of a corresponding element. If so, the bending stiffness is that the finger-like elements just "hang" a little bit, so this is permissible if at the operating speeds in question the roller is essentially horizontal by centrifugal force appropriately oriented elements.
  • Claim 18 characterizes the device by the roller in its attack on the web.
  • This attack can vary depending on its purpose and the properties of the web require different settings. This means that the roller can get closer to the web be moved so that the attack of the elements during the rotation of the roller becomes more or less firm. You can also change the speed and direction of rotation The roller can be changed to get the optimum effect to let work.
  • the attack of the roller on one in the back on the Attack not supported web.
  • the web will kept taut in the area of the attack and is below its longitudinal tension on the rotating roller. This will ensure the uniformity of the treatment effect conveyed across the width of the web, as with a fixed Backing up sometimes avoided unavoidable pressure peaks become.
  • An embodiment of the device according to claim 21 is characterized in that that to straighten the pole of a web, the roller in Synchronization with the web against the orientation of the lying pole attacks.
  • Lint removal in particular before dyeing or printing (claim 22).
  • Lint that is stored prevents the dye from entering or Printing paste to the web surface, so that at the location of a fluff bright spot or such a point remains.
  • Lint removal can affect the quality of the goods produced in this Terms to be improved.
