Definitions

  • the invention relates to a device for applying an embossing foil impression on a flexible material web with a heated embossing roller and with at least one pressure roller, by means of which embossing foil and material web can be pressed against one another and against the surface of the embossing roller.
  • Such a device is known from DE 32 10 551 C2.
  • There a number of pinch rollers are provided in pairs on a roller basket.
  • the pressure rollers can be adjusted individually, whereby first one or two adjacent inner pressure rollers and then progressively outwards the other pressure rollers can be brought into contact with the embossing roller. Esp.
  • sensitive flexible material webs such as, for example, banknote paper
  • the invention is therefore based on the object of providing a device of the type mentioned at the outset, with which undesirable compression of the fibers of the flexible material web and thus an undesired change in the properties of the flexible material web is avoided even with sensitive flexible material webs to be imprinted with an embossing foil impression without affecting the operating speed of the device.
  • each pressure roller is provided with an adjusting device for the defined adjustment of the distance of the corresponding pressure roller relative to the embossing roller surface and thus for the defined adjustment of the pressure exerted by the pressure roller on the embossing film and the material web.
  • the device according to the invention it is consequently possible, by suitably adjusting the distance of the corresponding pressure roller relative to the embossing roller surface, as a function of the wall thickness of the flexible material web to be embossed and as a function of the wall thickness of the embossing film, to match the embossing pressure between the embossing roller and the at least one pressure roller adjust so that it is advantageous when embossing sensitive flexible material webs such as Banknote paper an undesired compression of the paper fibers of the material web and thus a change in the paper properties is avoided.
  • the design of the device according to the invention has the advantage that thermal expansions of the embossing roller are compensated for, i.e. thermal expansion of the embossing roller does not result in changes in the distance between the embossing roller and the / each pressure roller.
  • the adjusting device has a pair of spacer rings which are provided on the two end sections of an axle which are at a distance from one another and on which the corresponding pressure roller is mounted, the spacer rings being mounted eccentrically on the corresponding axle.
  • the two spacer rings of the setting device of a pressure roller are each mounted on an associated eccentric sleeve which is fastened to the axis of the corresponding pressure roller. It is possible here for a single pressure roller to be provided on a corresponding axis, or for a number of pressure rollers to be provided, preferably spaced apart from one another.
  • the device By designing the device with the at least one setting device, it is easy and straightforward to set the distance between the at least one pressure roller associated with an axis and the embossing roller surface by rotating the axis and consequently by rotating the eccentric sleeves fixed to the axis, the The spacer rings belonging to the two eccentric sleeves bear against the embossing roller in any rotational angle position of the corresponding axis.
  • Each setting device can have a manually operated setting element.
  • This setting element is, for example, a rotary knob with a scale that can interact with a marking provided on the device in a stationary manner.
  • the manually operated adjusting member is therefore preferably provided for changing the angle of rotation position of the axis of the corresponding pressure roller located in the pressure position with respect to the embossing roller.
  • a particularly advantageous embodiment of the device according to the invention, for which an independent patent protection is sought, is obtained if the axial width of the / each pressure roller is smaller than the axial width of the embossing roller.
  • the ratio of the axial width of the / each pressure roller to the axial width of the embossing roller can be, for example, between 0.8 and 0.05, or larger or smaller.
  • Such a design of the device has the advantage, in particular, with a small quotient that the embossing roller can be made relatively wide compared to the width of the flexible material web to be embossed, so that in the axial direction of the embossing roller there is a virtually constant temperature profile in the area of the pressure roller , which affects the embossing behavior between the embossing roller and the relatively narrow at least a pinch roller has a positive effect.
  • the pressure roller is arranged at a distance from at least one of the spacer rings and a support roller is provided in the space between the pressure roller and the corresponding spacer ring, which has a slightly smaller diameter than the pressure roller.
  • the flexible material web is prevented from twisting as a result of the comparatively narrow support on the at least one pressure roller, which is narrow in comparison to the embossing roller, so that the sensitive flexible material web is not impaired, that is to say without undesired compression and the resulting change in material properties enables a high working speed to be achieved.
  • the at least one support roller has an axial length which is adapted to the distance between the pressure roller and the associated spacer ring.
  • the figure shows the device 10 for applying an embossing foil impression on a flexible material web with an embossing roller 12 drawn in sections, which can be heated.
  • the device 10 has rockers 16 on a base part 14 indicated in sections, one of which is indicated.
  • a pressure roller 24 is rotatably mounted on the axis 20 and has only a small axial dimension in comparison to the embossing roller 12. It is of course also possible to rotatably mount more than one pressure roller 24 on each corresponding axis 20.
  • the pressure rollers 24 on the associated axis 20 are preferably arranged at a distance from one another.
  • the distance between the individual pressure rollers can also be adjustable.
  • the / each pressure roller 24 is rotatably mounted on the axis 20 by means of roller bearings 26 known per se.
  • plate elements 28 are used, through which the corresponding axis 20 extends, and which are connected to one another and fastened to the corresponding rocker 16 are.
  • the pressure roller 24 is precisely centered on the associated axis 20.
  • An eccentric sleeve 30 of an adjusting device 32 is attached to each of the two opposite end sections of the corresponding axis 20, with the aid of a pin element 34, each of the two eccentric sleeves 30 having an eccentric section 36 with a wall thickness that changes along the circumference, as is readily apparent from the drawing is.
  • a spacer ring 38 is rotatably mounted on the eccentric section 36 of each of the two eccentric sleeves 30, with each spacer ring 38 being supported on the corresponding eccentric section 36 by means of roller bearings 40.
  • the two eccentric sleeves 30 belonging to an axis 20 are designed conformally and are oriented identically in the circumferential direction of the corresponding axis 20, i.e. arranged overlapping in the direction of the longitudinal center line 22 of the axis 20.
  • the two spacer rings 38 rest with their outer surface 42 on the cylindrical surface 44 of the embossing roller 12, so that by rotating the corresponding axis 20 around its longitudinal center line 22, it is possible to determine the distance between the embossing roller 12 or its surface 44 and the outer surface 46 of the associated pressure roller 24 as desired, in order to be able to set the pressure in a defined manner, which is exerted on the (not shown) embossing foil and the (not shown) material web which are moved through between the embossing roller 12 and the pressure roller 24 at a suitable working speed.
  • Support rollers 48 are indicated by thin dashed lines and can be provided on the corresponding axis 20 between the spacer rings 38 and the pressure roller 24.
  • the adjusting device 32 is designed with a manually operated adjusting member 50, with which it is possible to adjust the corresponding axis 20 and with it the two eccentric sleeves 30 at a suitable angle about the associated longitudinal center line 22 in order to adjust the distance between the embossing roller 12 and the Pressure roller 24 to be set as desired and the pressure between stamping foil and to be suitable for an exact stamping defining material web.
  • Support rollers 48 are preferably each assigned only to the outermost pressure roller of two pressure roller groups if the device 10 is spaced apart from one another and has pressure rollers 24 arranged axially parallel to one another, which - as described, for example, in the aforementioned DE 32 10 551 C2 - are combined into pressure roller pairs mounted on rockers 16 and arranged in two groups symmetrically to the embossing roller 12.
