Definitions

  • the invention relates to a pressure roller for the Pressing a first running web onto one second running web according to the generic term of claims 1, 2 and 13.
  • the US 43 27 467 A describes a pressure roller, wherein several gas-filled between support tube and pressure jacket Cells are provided.
  • the pressure in the cells is not above the axial one Partially adjustable direction.
  • DE 19 40 175 A describes a roller Pressure treatment of flat materials. Between one Roll core and roll shell are arranged inflatable bodies, which are subjected to different pressures can.
  • the US 37 06 119 A shows a pressure roller Treatment of webs. There are a number of gas-filled cells arranged individually with air are acted upon.
  • the invention has for its object a good an uneven surface of a rotating supply roll adaptable pressure roller of light design for the connection a running web with an adhesive provided the beginning of the supply role.
  • the invention in particular the following Advantages achieved: due to the arrangement of one or several gas-filled cells between the support tube and the elastic pressure jacket has made it possible a good on an uneven surface of a new one Supply roll of adjustable pressure roller for pressing to create two running paper webs. It points the pressure roller according to the invention has a low mass on what a quick employability of the Pressure roller is advantageous. Furthermore, it is at least in one embodiment of the pressure roller possible the compressibility of the pressure roller both generally as well as partially over the axial length adjustable. The latter is special advantageous if over the paper web width Section or different sections with another Hardship must be applied, e.g. B. when pressed of so-called adhesive labels.
  • the Cells 14 can each have a cylindrical shape, consist of foil and area next to - and in a row (Fig. 3) on a flexible Backing material 16, e.g. B. film, placed airtight be.
  • This with cells 14 filled with gas or air equipped carrier material 16 can have a width, that of the usable axial length of the pressure roller 1 corresponds.
  • the material 14, 16 can be multilayer and spiral to the axis of rotation 17 of the pressure roller 1 be wound on the support tube 2 so that the Side edges of the carrier material 16 on the inside annular covers 7 abut. So that's the room 13 filled with compressible material 14, 16.
  • Such material 14, 16 can be commercially available Bubble wrap exist. Parts 2, 3, 4, 6, 7, 8 are duplicated, but only shown one.
  • the cells 14 are in an unspecified one Variety available. Peripheral cells 14 form one Shell surface 28, which is the running surface of the pressure roller 1 can serve. However, this is expedient peripheral lateral surface 28 of the cells 14 from one elastic pressure jacket 9 surround so that this Tread forms. However, it is also possible for everyone To connect cells 14 to each other, e.g. B. means tubular connections, so that between the cells 14 a defined air balance can take place.
  • a second embodiment one is shown with the pressure roller 21, whose Support tube 2 at each of its two ends 6 Receives ring flange 22. Both ring flanges 22 instruct each of the flanks 23 facing one another circular groove 24, in each of which the end 8th an elastic pressure jacket 9 is attached so that between the outer surface 11 of the support tube 2 and the inner lateral surface 12 of the elastic Pressure jacket 9, delimited by the ring flanges 22 hollow cylindrical space or cell 13 results in which by means of a in the pressure jacket 9 arranged Valve 26, which is designed as a check valve compressed air can be introduced. So is the cell 13 also with compressible material equipped, the air pressure in the cell 13th refillable by means of a known compressed air source and is therefore also adjustable (Fig. 4).
  • the ends 8 of the elastic Pressure jacket 9 also on the outer circumference 27 of the Ring flange 27 be shrunk.
  • knobs 33 are only open the inside 31 of the elastic pressure jacket 29 and 6, the knobs 34 on the outside 32 of the elastic pressure jacket 36 shown. You can the knobs 33; 34 conical or cylindrical be trained.
  • elastic pressure sleeves 29; 36 can these on the inside 31 or outside 36 spaced from each other at a distance, in peripheral Circumferential rings 37; 38 have (in FIGS. 5 and 6 as a second reference symbol, separated by semicolon, designated).
  • a height h the Knobs 33, 34 or the rings 37, 38 corresponds at least one thickness d of the elastic pressure jacket 29; 36.
  • the rings 37 (Fig. 5) can at their upper and lower edges rounded, so that these in Cross section an approximately conical to frustoconical Take shape.
  • the rings 38 are sharp-edged shown.
  • the elastic pressure jacket 36 can be embodied as a variant on the outside instead of the knobs 33 in each other Distance of approx. 0.25 times a spaced "spines" elastic material, e.g. B. rubber, have a Height which is greater than the height h of the knobs 33, 34 or the rings 37, 38.
  • an elastic Pressure jacket 9 seen in longitudinal section, to form wavy lines.
  • That for the elastic Pressure coats 9; 29; 36 material used can e.g. B. are made of rubber.
  • That used for the support tube 2 Material can be made of metal, fiberglass or carbon fiber reinforced material.
  • Valves 47, 48, 49, 50 can be charged with gas separately is.
