Definitions

  • the invention relates to a deflection roller for an embossing machine, for deflecting a Stamping foil web and / or a substrate web to be stamped.
  • a deflection roller which is for use in a Textile machine, i.e. which is intended for deflecting a textile web, where on a machine-fixed roll mandrel a porous air-permeable mandrel sleeve with their axially distant end portions is fixed, being on the mandrel sleeve a roller sleeve is mounted, and wherein the roller mandrel for a compressed air channel Acting on the mandrel sleeve with compressed air, which forms a Air cushion is provided between the mandrel sleeve and the roller sleeve.
  • Textile Sheets usually have a relatively high mechanical strength, so that friction-related inadmissible stretching or stretching of the web material There is no need to fear this, especially during a start-up process. Be different the conditions for thin and narrow embossed foil webs.
  • DE 44 16 421 A1 discloses one for transporting and tempering sheet-like materials suitable heatable and coolable roll, which is characterized by a extremely low bearing friction.
  • a fluid is used that between the roll shell and the roll core mainly in the circumferential direction flows.
  • the fluid can also be used to temper the roll jacket become. Because the fluid used for temperature control is in the range of usable Roll width preferably flows in the circumferential direction, is an excellent Constant temperature achieved across the roll width.
  • the invention has for its object a deflection roller of the aforementioned To create type that has a comparatively small friction, so that thin and narrow film webs are not stretched inadmissibly, and with which performance of an embossing machine, i.e. an increase in Machine speed of the order of 50% can be achieved.
  • each Roller sleeve is mounted almost smoothly, so that an increase in performance, i.e. a Increasing the machine speed to the order of 300 m / min is possible.
  • Another advantage is that the permanent Acting on the at least one air-permeable mandrel sleeve and the at least one a roller sleeve mounted on the at least one mandrel sleeve also when starting off the embossing machine equipped with deflection rollers according to the invention So-called breakaway torque of the pulleys is minimal, so that during the The embossing machine starts a rapid increase in machine speed is possible.
  • FIG. 1 and 2 show a first embodiment of the for an embossing machine provided deflection roller 10, which on a frame 12 drawn in sections the embossing machine is stored.
  • the deflecting roller 10 has a roller mandrel 14 which is fixed to the frame 12 by means of a fastening screw 16.
  • the machine-fixed Roll mandrel 14 is formed with a compressed air channel 18.
  • the roll mandrel 14 has also two axially spaced apart bearing sections 20 and 22 on which a porous air-permeable mandrel sleeve 24 with their two axially from each other distal end portions 26 and 28 is set.
  • the machine-fixed roll mandrel 14 With a Center section 30 of reduced diameter formed so that between the An annular gap 32 in the middle section 30 and the porous mandrel sleeve 24 results.
  • the compressed air channel 18 opens out from the central section 30 and into the annular gap 32 a.
  • the compressed air channel 18 is used over the annular Gap space 32 for pressurizing the porous mandrel sleeve 24 with compressed air.
  • a roller sleeve 34 is axially immovable stored on the porous mandrel sleeve 24, a roller sleeve 34 is axially immovable stored.
  • the machine-fixed roll mandrel 14 to the Bearing section 20 formed adjacent to a circumferential collar 36 on the the air-permeable porous mandrel sleeve 24 rests with its one ring end face 38.
  • a Washer 42 fastened with the aid of a fastening screw 44.
  • the roller sleeve 34 rotatably mounted on the porous mandrel sleeve 24 stands with its an end portion 46 over the circumferential collar 36 and with it axially removed second end portion 48 graded over the disc 42.
  • compressed air channel 18 is pressurized with compressed air, this results in between the porous air permeable mandrel sleeve 24 and the roller sleeve 34 an air cushion 50 and thus, as it were, a friction-free mounting of the roller sleeve 34.
  • the compressed air then escapes between the circumferential collar 36 of the machine-fixed Roll mandrel 14 and the first end portion 46 of the roller sleeve 34 and between the Washer 42 and the second end portion 48 of the roller sleeve 34 so that it during the operation of the embossing machine is required, the compressed air channel 18 permanently with compressed air - or another suitable compressed gas.
  • a contact element in the vicinity of the deflection roller 10 denotes, with which an unwanted jumping off around the pulley 10th deflected (not shown) stamping foil web and / or the to be stamped Substrate web is prevented.
  • roller sleeve 34 For precise guidance of the embossing foil web and / or the one to be embossed Substrate web is the roller sleeve 34 at its two axially distant from each other End sections 46 and 48 each with a circumferential coil collar 54 educated.
  • FIG. 3 and 4 show a second embodiment of the deflection roller 10, with one Frame 12 of the embossing machine a number of deflection rollers spaced apart are provided side by side. Is between adjacent deflection rollers 10 one contact element 52 is provided in each case.
  • the deflection roller 10 are two porous air-permeable on the respective machine-fixed roller dome 14
  • Mandrel sleeves 24 are fixed adjacent to each other, on which a roller sleeve 34 axially immovable is rotatably mounted.
  • the machine-fixed roll mandrel 14 with bearing sections 20 and 22 and also with a middle bearing section 56 is formed.
  • the bearing sections 20 and 56 delimit a central section 30 of reduced diameter.
  • the bearing sections 22 and 56 define a second central portion 30 of reduced diameter.
  • the Central sections 30 of reduced diameter open channel branches 58 of the im machine-fixed roller mandrel 14 formed compressed air duct 18.
  • the compressed air duct 18 is only in the deflection roller 10 according to FIGS. 1 and 2 formed with a single channel branch 58.
  • the machine is fixed Roll mandrel 14 of the respective deflection roller 10 adjacent to the bearing section 20 formed with a circumferential collar 36 on which the associated one air-permeable mandrel sleeve 24 rests with its annular end face 38.
  • a washer 42 is fastened by means of a fastening screw 44.
  • Disc 42 With the help of Disc 42 is the associated air-permeable mandrel sleeve 24 together with the first Mandrel sleeve 24 between the disc 42 and the circumferential collar 36 axially fixed immobile.
  • the roller sleeve 34 is axially immobile on the two porous mandrel sleeves 24 rotatably mounted. If compressed air channel 18 is pressurized with compressed air, this results an air cushion 50 between the porous mandrel sleeves 24 and the roller sleeve 34, by means of which the roller sleeve 34 is mounted so that it can be rotated virtually without friction.
  • FIG. 5 and 6 illustrate a third embodiment of the deflection roller 10 Embossing machine for deflecting an embossed foil web (not shown) and / or a substrate web, not shown, to be embossed, with a long machine-fixed, horizontally arranged roll mandrel 14 a number of porous air-permeable mandrel sleeves 24 are fixed spaced apart.
  • the porous dome sleeve 24 are spaced apart on the machine-fixed roller mandrel 14
  • Spacer rings 59 arranged.
  • To fix the porous dome sleeves 24 on the long Machine-fixed roll mandrel 14 is formed with bearing sections 20, 56. Between adjacent bearing sections 20, 56 and between adjacent Bearing sections 56 is in each case a central section 30 of reduced diameter from which an associated duct branch 58 of a compressed air duct 18 of the mandrel 14 opens out.
  • a roller sleeve 34 is axially immovable stored on each porous mandrel sleeve 24, a roller sleeve 34 is axially immovable stored. If the compressed air duct 18 with compressed air or another suitable Pressurized gas is applied between the respective porous mandrel sleeve 24 and the associated roller sleeve 34 an air cushion 50 and thus a quasi frictionless storage of the respective roller sleeve 34.
  • the same details are in 5 and 6 with the same reference numerals as in Figs. 1 to 4, so that it is superfluous in connection with FIGS. 5 and 6 all these details to describe in detail once.
