Definitions

  • the invention relates to a roller with a rigid body and an elastic coating applied thereto.
  • the invention relates to a spreader roll for spreading continuous flexible web material.
  • a spreader roll for spreading of running flexible web material comprising a terminal journal bearing rigid roller body.
  • a jacket-shaped coating of elastomeric material is applied on the roll body.
  • the elastomeric pad contains outgoing from its lateral surface, to the longitudinal axis of the roller body oblique incisions, which are inclined on both sides of the radial center plane of the roller respectively to the relevant end of the roller from the inside out.
  • the cuts are in the form of uniform helices and cause a spreading during operation.
  • the inner incisions are offset by 1 80 ° from each other.
  • the outer edges facing the radial center plane of the roll are rounded or folded.
  • An elastomeric coating wears off within a few years. A roller body is then freed from the remaining surface and applied a new coating. Spirals are then cut into this newly applied coating. Finally, edges are rounded off at the covering surface.
  • the preparation of the cuts in the covering contributes greatly to the recovery costs of such a roller.
  • the elastomeric pad is relatively thick to make suitable deep cuts can.
  • Commercially available spreader rolls of this type have at least 1 5 mm thick elastomeric coating on the rigid roll body. From the document US 2 594 846 a Breitstreckw ⁇ lze is known which consists of two roll body sections with u. a. conically tapering lateral surfaces consists. This also has angled incisions whose inclination changes to the ends of the roller, resulting in high manufacturing costs.

  • the roughened surface may be spiraled.
  • a rough metallic surface is unsuitable for thin webs that can easily be damaged.
  • US Pat. No. 6,12,807 discloses a roller with a diamond powder coating.
  • the coating is relatively expensive and at least less suitable for sensitive webs.
  • an elastically deformable layer is applied to a rigid, preferably cylindrical base body.
  • the basic body does not necessarily have to be a straight cylinder.
  • a concave shape or a banana shape of the main body is also possible.
  • the elastically deformable layer may consist of a rubber or of an elastomer.
  • the surface of this elastic layer is processed so that a roughened or textured surface is preferably formed in the form of two oppositely extending helices.
  • the cylindrical basic body may be a conventional, for example from the document WO 2005/1 1 8446 known, in particular consisting of a metal roll body.
  • the cylindrical base body may also be merely a sleeve, which preferably consists of a plastic, particularly preferably of a fiber-reinforced plastic.
  • the cylindrical base body is preferably in one piece, but may also consist of several parts, so for example be composed of two parts.
  • That the elastic coating is roughened on its surface means that the roughness is formed by the elastic coating and not by foreign material such as diamond powder or sticking a roughened layer.
  • the roughness is thus achieved by a large number of small depressions in the elastic coating.
  • the depressions are typically 0, 1 to 1 mm deep.
  • the mean distance between two wells and the mean diameter of the wells are also typically between 0.1 to 1 mm.
  • the creased or textured surface is relatively slip resistant compared to non-roughened areas. The roller can therefore even be used as a guide roller, guide roller or web guide roller in particular without its own drive, if it depends on particularly non-slip surfaces.
  • the entire surface of the elastic covering may be roughened.
  • circumferential, for example annular depressions of, for example, 0.1 to 1 mm depth on the surface in order to be able to reliably guide out a fluid which is located between an adjacent material web and the roll surface.
  • the roller is rotated due to the good adhesion by the adjacent web of material when the web is transported in the usual way.
  • the roller thus basically has no own drive, so that the roller could rotate independently of the movement of the material web. Costs for a separate drive are therefore not required.
  • the diameter of the is then not vote on their own drive, which is an additional advantage.
  • the roller is then expediently stored very smoothly, so that only slight frictional forces have to be overcome for turning.
  • the two helixes thus produced have a comparatively non-slip surface Widening of M ⁇ teri ⁇ lb ⁇ hnen. Since no relatively deep cuts must be made, as this z. B. be provided according to DE 295 22 01 1 U l, the flexible layer can be very thin. It can be compared to the prior art, are provided in the relatively deep cuts, material and thus cost savings. Also, the production of a helically roughened or textured surface is relatively inexpensive compared to the case where helices are provided by cuts. A helical roughening can be achieved inexpensively by grinding. Since no relatively deep cuts z. B.
  • the invention is based on the idea of providing low-cost, oppositely helically extending surfaces starting from a central region, which are non-slip, ie grippable, in comparison to adjacent surface regions. If the elastic covering is already very anti-slip from the very beginning, it may suffice that only the surfaces adjacent to the oppositely helically running surfaces are slightly shaped, for example not more than 1 mm, preferably not more than 0.5 mm, more preferably not more than 0 2 mm deepen to achieve the desired goals. In general, however, it will be necessary to roughen the helical surface areas in order to achieve the required slip resistance of these surface areas.
  • the elastically deformable coating may be thin. It suffices a lining thickness of a few millimeters. For a single use even a lining thickness of a few tenths of a millimeter is sufficient.
  • An example, 1 0 mm thick, elastic layer to apply, is advantageous if the coating after wear according to the invention in the manner described to be restored. Also for manufacturing reasons, it is advantageous to first apply a several millimeters thick elastic layer.
  • An elastic covering applied on a rigid body for the first time will therefore be at least a few millimeters, and in particular at least 3 mm, preferably at least 5 mm, in principle.
  • lower layer thicknesses of less than 3 mm are only present if the covering has been abraded several times as a result of wear and provided with the helically running rough or structured surfaces and as a result of the elastic covering has become progressively thinner. Only in this way are layer thicknesses of the elastic layer of 0.2 to 3 mm achieved in practice.
  • the elastic layer When provided with incisions spreader rolls, which are obtained for example according to DE 295 22 01 1 U l, the elastic layer is at least 1 5 mm thick. In contrast to such a prior art in the present invention, a thickness of the elastic covering of up to 1 2 mm, preferably of up to 1 0 mm is sufficient.
  • areas which are adjacent to the helical roughenings or depressions are recessed.
  • improved spreading effect is achieved.
  • the transport of a web to the outside (spreading) takes place by webs with roughened surface.
  • the depressions are not incisions of several millimeters.
  • a depression is instead only a few tenths of a millimeter, for example, only 1/1 0 millimeters.
  • the wells are only intended to be a direct contact between a wide web of material to be stretched and the areas which are not generally roughened during spreading is avoided. A material web should thus rest firmly on the roughened areas due to the depressions during a spreading, but not on the areas that lie in between.
  • the depth of a depression is therefore advantageously chosen so that on the one hand this goal is achieved and on the other hand a depression as small as possible fails. If a depression is very small, then a material web can not get into a depression in such a way that damage to the material web is to be feared thereby. Basically, therefore, a depth of 1 mm is not exceeded. In general, the depth is well below this value and is less than 0.5 mm.
  • Helical depressions between the helically roughened surfaces not only support a spreading effect, but can also advantageously ensure that a fluid, in particular a liquid, can be diverted therefrom so as to improve the adhesion between a material web and the roll.
  • the helical depressions can be made cheaply and quickly by grinding.
  • the intended helical surface area is patterned by means of a laser. Although it can be roughened by grinding the desired surface cheaper.
  • a surface roughened by grinding becomes unstable or brittle. This leads to a relatively fast abrasion and a relatively short service life of a manufactured spreader roll. Particles that detach from the surface of the roll can get into a web and thereby contaminate or even damage it.
  • the surface treatment by means of laser is to be preferred in order to arrive at a structured, grippier surface. Damage to the surface resulting in increased abrasion is thus avoided.
  • the spreader roll surfaces be made reproducible. A spreader roll type can thus be produced as often as desired identical to an identical surface. Thus, if a specific embodiment of a surface has proved to be particularly suitable or practical, the same three-dimensional surface structure can always be restored.
  • a mask can be used. Through openings in the mask, laser light reaches the surface to be roughened. Components of the surface are thus removed without damaging adjacent areas.
  • the laser is preferably computer-controlled and moved so that the desired rough surface is formed. After processing, there is a surface that is no longer smooth but, for example, has small recesses distributed over the surface.
  • the recesses are preferably very small. The dimensions of the recesses are in particular in the range of a few tenths of a millimeter or even in the range of a few hundredths of a millimeter.
  • the maximum diameter of a recess is preferably less than 1 mm, more preferably less than 0.5 mm.
  • the minimum diameter of a recess is preferably more than 0.01 mm, more preferably more than 0.05 mm.
  • the maximum depth of a recess is preferably up to 1 mm, more preferably up to 0.5 mm.

  • a herringbone pattern could be created in the surface to increase the grip properly.
  • a rough, helical surface is produced by means of a laser
  • the areas are likewise removed by means of the laser, which adjoin the helical, rough surface. This creates the desired helical depressions, on which a material web should not rest during the spreading.
  • the desired surface of a spreader roller in a single operation can be produced.

  • the rough area has a plurality of recesses with a depth of 0.5 mm
  • the helical recesses are also 0.5 mm deep.
  • This embodiment makes it possible to produce helical depressions and recesses in one operation with the aid of a laser.
