Definitions

  • This disclosm relates to a device f passing u H through rolls to remove or squeeze from the l Field of Search 29/1 13 AD, 1 16 webs.
  • the rolls are made with a covering ofa thin layer 29/132 of a synthetic material.
  • a roll having a 1 to 5 mm layer of polyurethane is useful for squeezing References Clted and dewatering textile webs.
  • a narrow pressure zone may be obtained, for purely geometric reasons, when the roll diameter is small.
  • deflection-free rolls particularly the so-called swimming rolls, makes an equal application of high pressure over the entire length of the roll possible at small roll diameters.
  • the limit of the squeezing effect achieved when using smooth rolls which have compact surfaces is improved by fiber rolls wherein the roll body consists of thin discs layered upon each other and compressed which consist of a latex-saturated nonwoven fabric. This is due to the penetration caused by the specia structure of the roll surface of the roll into the fiber space of the web, particularly into woven or knitted textiles.
  • An object of this invention is to produce improved squeezing effects without the use of a pressure which would damage the treated web.
  • the stress of the thin roll coat in the roll nip is extraordinary large. While rubber coatings were destroyed after a few roll rotations, tests have shown that polyurethane is a working material which brings particularly useful life times. While it depends on the material to be squeezed when using solid plastic rolls whether a harder or a softer roll brings the better results, the thin coats according to this invention showed that the best results can be obtained by the use of a relatively soft coat.
  • a preferred embodiment is provided with a polyurethane coat of l to 3 mm thickness having a hardness of about to shore A.
  • Rolls of relatively small diameter are preferred, such as about to 300 mm in diameter. Such rolls deflect unless special provisions are undertaken under the high working pressures used over the width of the web which leads to a lower pressure in the middle of the web.
  • the inner roll is preferably constructed as a deflection-free roll, particthe plastic materialthe roll is finished in the usualway.
  • FIG. 1 shows a side view of a roll pair one of which is a roll according to invention, partially in longitudinal cross section;
  • FIG. 2 shows a cross section according to line 11- in FIG. 1.
  • the preferred embodiment shows a roll pair 1, 2 of which at least the upper one roll 1 is constructed as a swimming roll. Both rolls may be of the same construction.
  • the swimming roll 1 comprises a rotating roll body 3 which is supported on a stationaryinside beam 4. Sealings Sand 6 are provided which separate the inner space between the inner beam 4 and the roll body 3 into two longitudinal chambers 7 and 8. Longitudinal chamber 8 facing the counter roll 2 can be loaded by pressure means through a feed 9.
  • the force applied by the pressure means is equally transmitted ontothe roll body whereby the inner beam 4 absorbs the force and can deflect somewhat without impairing the equality of the pressure of roll body 3.
  • a thin polyurethane coat of about one to five millimeters is applied which comprises the working roll periphery.
  • the coating in the drawing is not to scale; the coating was drawn thicker so it is clearer. The best results are obtained at a relatively low level of hardness of the coating of about 75 to 85 shore A.
  • the table at pages 8 11 shows the improvement obtainable with the roll of this invention.
  • the table indicates the residual moisture content after squeezing based upon the air-dry weight of the material. Except where indicated otherwise the tests were made with a working pressure of 50 kg/cm at a working speed of 30 m/min, with rolls of equal diameter of 240 mm.
  • the perlon fiber roll consisted of latex-saturated perlon fiber non-woven fabric discs which are arranged on the roll body and are pressed together to a compact roll.
  • PU is polyurethane
  • the figure below the material indication states the hardness of the roll in shore A.
  • the thickness of the coatings on the rolls are indicated in the headings of the columns, and were from 1 to 15 mm.
  • the coatings for the rolls of columns 2 6 were 15 mm.
  • the gram-figures stated for the different materials are the figures for the weight per unit area of the corresponding material.
  • the table shows that an improved squeezing effect was obtained for the rolls having a thin coat compared to the usual rolls having a thick plastic coat.
  • An increase of the working pressure did not lead to considerable improvement, but resulted in an increased stress on the material.
  • the improvement made with the invention is relatively small when treating especially heavy materials. This is understandable because the thickness of the material is already comparable with the coat thickness of the roll.
  • the coat of the roll if it is supposed to conform to the material and penetrate the unevenness of the surface, is subject to relative considerable stretch.
  • the result obtained is clearly superior to the perlon fiber roll. Again, exceptions are the especially heavy materials.
  • the roll according to the invention and the perlon fiber roll show about the same achievements when treating wool.
  • the roll having the 1 mm coating shows a clearly superior effect when treating synthetic knitted material and light cotton material compared to the roll having a 3 mm coat.
  • the invention is not limited to this area of application.
  • the roll according to this invention is also suitable, for example, for paper production and similar fields.
  • a polyurethane shell having a Shore A hardness of about to 85, and a thickness of about 1 to 5 mm, affixed to and around said hollow shell.
