Definitions

  • the invention relates to a method for exposing a clamping slot on the forme cylinder side associated with the hooking claws of gravure winding plates, which is sealed radially inward by means of a sealing strip and provided with a filling made of hard material radially outside of the sealing strip.
  • Another inventive idea relates to an advantageous device for performing this method.
  • Another object of the present invention is to simultaneously provide a simple and reliable device for performing this method.
  • the solution according to the invention relating to the procedural part of the task consists in softening or melting from a plastic which at least softens or melts the action of heat when the tensioning slot is exposed by exposure to the tensioning slot side.
  • the slot-side heating of the filling material ensures easy removal of the filling.
  • Transferring the plastic forming the filling into a soft, doughy phase can weaken the mutual connection of the beaking edges laterally bounding the clamping slot or the hooking claws extending over the filling, so that the clamping device assigned to the beaking edges can be actuated in the relaxation direction, in many cases the filling is already torn and the connection of the beak edges thus caused is dissolved, or in any case such mobility is achieved that removal of the winding plates is possible.
  • the solution according to the invention relating to the device-related part of the task consists in that at least one heating line is provided in the area of the tensioning slot or the walls delimiting it, which heating energy can be applied to from one end of the cylinder.
  • a gravure forme cylinder equipped in this way permits simple slot-side heating of the slot material and can therefore greatly facilitate the handling of the filling which softens or melts when exposed to heat. There is generally good accessibility in the area of the cylinder end face, which can make the connection of the heating line to an appropriate energy supply very simple.
  • the heating line can have a loop with two branches which are laid in parallel and connected in series and are connected to one another in the area of a cylinder end face and at their end in the area each of the opposite ends of the cylinder end faces has connection elements for corresponding supply and disposal lines. This ensures in an advantageous manner that the heating line can be operated both on the supply side and on the disposal side from a cylinder end face, which can simplify and simplify the connection to a corresponding energy supply and at the same time advantageously results in a large heating line length.
  • the heating line can have a heating wire which can be acted upon by electric current.
  • a further advantageous measure can consist in that the heating line is received in an assigned channel, preferably closed on the slot side, which enables protected accommodation of the heating line, which can therefore be used again and again.
  • the channel receiving the heating line can be thermally insulated radially inwards by means of an asbestos strip or the like. This measure advantageously results in an increase in the heat flow to the tensioning slot and thus to the filling material.
  • the gravure printing cylinder on which FIG. 1 is based and which is suitable for accommodating winding plates 1 has at least one pit 2 which interrupts its circumference and is delimited by lateral beak plates 3 and 4, on which the hooking claws 5 of the winding plate or plates 1 can be suspended.
  • the hooking claws 5 are pressed against the respectively assigned beak edge 3 or 4 by means of continuous clamping strips 6, which can be actuated by means of an eccentric shaft or the like, not shown.
  • One of the beak edges 3 or 4 can be swiveled in and out in the radial direction in order to facilitate the hooking in of the hooking claws 5.
  • the beak edges 3 and 4 are moved towards one another.
  • one beak edge can be arranged stationary with respect to the cylinder axis and the other beak edge can be arranged rotatably with respect to the cylinder axis.
  • the beak edges 3 and 4 do not abut each other even in the tensioning state on which FIG. 1 is based, so that there is a clamping slot 7 which is laterally delimited from the beaking edges 3 and 4 or from the hooking claws 5 which cross over these, which is filled with a filling 8 to achieve a smooth cylinder surface.
  • the filling 8 consists of a plastic that becomes soft or dough under the influence of heat, e.g. B. from a heat or light-cured polymer, such as an acrylate resin.
  • the cylinder is provided with a heating device in order to bring about a possible heat effect on the filling material.
  • the heating device simply consists of a heating line 9 extending over the entire cylinder width, here simply in the form of a heating wire 11 provided with heat-resistant insulation 10, which can be supplied with electrical current to form an electrical resistance heater.
  • the heating wire 11 as can be seen in FIG. 2, is provided in the region of its ends with connection elements formed by plug sockets 12 for corresponding supply and disposal cables.
  • the heating line 9 has two branches 13 and 13a, which run parallel to one another and are connected in series in terms of the current flow, as FIG. 2 also shows.
  • the heating line 9 simply forms a loop with two parallel branches which are connected to one another by an arch 14 in the region of a cylinder end face.
  • the heating line 9 can simply be formed by a one-piece, approximately U-shaped shaped piece. If the two branches 13 or
  • the branches 13 and 13a of the heating line 9 are fixed on mutually movable cylinder parts, a removable bend 14 can be advantageous, so that with corresponding movements, for example in the case of the tensioning or relaxing process, no constraining forces can occur.
  • the branches 13 and 13a can be provided on the arch side with connecting elements formed here by plug sockets 15, onto which the arch 14 provided with corresponding counterparts can be attached.
  • a corresponding excess length would have to be provided in the region of the arch 14 in order to avoid constraining forces.
  • the heating wire forming the heating line 9 can simply be inserted into the tensioning slot 7 or glued to the radially outer end faces of the tensioning flaps 6. In this case, the heating wire is practically embedded in the material forming the filling 8, so that when the heating wire is activated, the filling 8 is heated quickly.
  • the heating line 9 can expediently be designed in the form of a film cable which has a heating conductor embedded in an adhesive film.
  • the tensioning flaps 6, as can best be seen from FIG. 1, are provided in the region of their radially outer ends with a channel 16 which extends over the entire length of the flap and into which a heating line 9, here in the form of an insulation jacket 10, is provided Heating wire 11, can be inserted.
  • Each channel 16 can be assigned a heating wire loop, which is provided at its ends with plugs 12 for connecting supply and disposal cables.
  • the two channels 16 of the two clamping flaps 6, which are arranged opposite one another at the same height, are each a branch 13 or 13a of the heating line forming a single loop 9 assigned, which results in a particularly compact channel cross section.
  • an asbestos strip 17 is placed in each of the channels 16, which shields the heating line 9 inwards.
  • the channels 16 are covered towards the clamping slot 7 by means of a cover plate 18.
  • the branches of the heating line 9 arranged in the closed channels 16 are reliably protected against damage or contamination, which means that a long service life can be expected.
  • a heating medium could also be used to form a heating line, e.g. B. with a hot gas, etc., can be acted upon pipeline provided the use of electric current should raise safety concerns.
  • cover hoods 19 are provided in the area of the cylinder end faces, which protect the sockets 12 and 15 and possibly exposed parts of the heating line 9, in the present case the bend 14.
  • the cover hoods 19 can simply be attached to the support rings 20 provided on the end face.
  • the winding plate 1 can only be removed from the cylinder when the hooking claws 5 are exposed.
  • the filling 8 of the clamping slot 7 must be removed or in any case weakened in such a way that the movable beak edge 4 can be displaced with respect to the stationary beak edge 3.
  • the heating line 9 installed on the cylinder side is activated. The heat given off by this gives way to the filling 8 that the movable beak edge 4 is movable. In the course of this movement, the softened filling 8 is pulled apart and sheared off as a result of the transverse forces which become effective here. If this should not yet be fully achieved by moving the beak edge 4, a corresponding shearing off results in any case when the corresponding suspension claw 5 is removed.
  • the filling 8 which can be softened or melted by means of the heating line 9 can have been introduced into the tensioning slot 7 by customary methods.
  • the radially inner boundary of the clamping slot 8 can simply form a sealing strip 23 inserted into a corresponding groove of the clamping strips 6 and arranged radially inside the heating line 9, so that there is a mold cavity which is closed radially inwards.
