Definitions

  • the invention relates to a strand manufacturing machine for the production of products of the tobacco processing industry according to the preamble of claim 1 and a format part for a strand manufacturing machine according to the preamble of claim 10, and a method for producing a format part according to claim 12.
  • an endless strand of non-form-fixed tobacco or filter material is generally placed on a longitudinally moved wrapping strip and molded into a solid strand during transport movement of the wrapping strip by flipping and gluing the side edges of the wrapping strip.
  • the wrapping strip rests on an endless, in the direction of the transport movement driven format strip.
  • the format tape in turn rests on a format base, which is formed from one or more format bases, and is provided with a groove having an increasing depth in the direction of transport movement with a decreasing radius of curvature. Due to the groove provided in the format reason with the decreasing radius of curvature is the fitting format tape with the overlying wrapping strip during the transport movement with the side edges of the side of the strand turned up and formed in the lower half to a semicircular cross-section.
  • side edges of the wrapping strip is understood to mean the lateral edge sections of the wrapping strip, which are wrapped around the strand for wrapping around the strand.
  • Such a strand-making machine with designated there as format garnish format parts is for example from the DE 36 24 098 A1 known.
  • the wrapping strip of the finished products which holds the strand together, should be as wrinkle-free and without markings as possible.
  • the side edges of the wrapping strip as clean as possible around the strand herum ⁇ around the strand and finally superimposed before they are glued together.
  • the invention has the object to provide a strand-making machine and a format part with which the production of products with a strands as possible wrinkle-free enveloping strip is possible.
  • the abutment surface is shaped in such a way that the intersection lines of at least one section of the abutment surface with cutting planes perpendicular to the direction of transport movement of the encasing strip have a parabola section.
  • the advantage of the solution according to the invention is the fact that the side edge of the wrapping strip is placed by the proposed shaping of the contact surface with the parabola section in a very gentle envelope movement around the strand, since the contact surface by the parabolic section, starting from the voltage applied to the format base Edge of the contact surface, has decreasing curvature.
  • the folding movement of the side edge can be determined in detail by the shaping of the parabolic section, e.g. by the choice of the order of the parabola or by the determination of the coefficients of the form of the parabola determining parabola equation, be further tuned to the individual strand.
  • a particularly gentle envelope movement of the wrapping strip can thereby be achieved if the contact surface is shaped such that the wrapping strip tangentially abuts the parabolic section of the cutting lines of the contact surface.
  • the contact point of the parabolic section of the cutting lines of the contact surface is preferably the starting point the side of the parabola section which has the greater curvature. Due to the tangential orientation of the parabola section in the contact point on the wrapping strip, the parabola section is tilted overall onto the strand, so that the side edge of the wrapping strip is already moved towards the strand in the area of the upper section before it reaches the final diameter of the product or the product Target diameter of the emerging from the forming section strand is wrapped around the strand.
  • the envelope movement of the side edge is thus not abrupt, but by gently bringing the side edge, whereby the risk of wrinkling can be further reduced.
  • the abutment surface is shaped such that the cutting lines of at least a portion of the abutment surface with sectional planes perpendicular to the direction of transport movement of the wrapping strip have a circular arc portion beginning from the edge of the abutment surface abutting the format base.
  • the circular arc portion shape of the contact surface of the strand can be fixed in the height of the already folded portion of the side edge of the wrapping strip in a diameter which corresponds to the diameter of the final product or at least the diameter of emerging from the forming section strand including the wrapping strip enveloping this ,
  • the abutment surface is shaped in such a way that the angles of the circular arc sections of the cutting lines succeeding one another in the direction of the transport movement of the wrapping strip increase at least in a section of the abutment surface.
  • a particularly clean and wrinkle-free formfixierter strand can be achieved in this case, when the contact surface is formed such that the cutting line is formed on the exit side of the strand from the limited by the format part forming channel of the forming section exclusively by a circular arc section.
  • the proposed shaping of the contact surface of the strand after completion of the folding movement of the side edge with the wrapping strip can be particularly well fixed in its shape to the final diameter of the product or the diameter corresponding to a desired diameter after exiting the shaping section, the side edges in particular in the section of the adhesive section defined by the adhesive section just curved according to the circular arc shape are formed.
  • the abutment surface is shaped in such a way that the parabolic sections of the cutting lines adjoin the circular arc sections.
  • the parabolic section adjoining the circular arc sections of the cutting lines following one another in the direction of the transport movement of the wrapping strip have a constant shaping and a changing orientation due to the increasing angle of the circular arc sections.
  • the parabola section of the cutting lines of the contact surface serves the purpose according to the invention of gently turning over the side edge.
  • the folding point also changes at the circumference of the strand at which the side edge of the wrapping strip is turned around the strand to the diameter of the circular arc section. The transfer point thereby moves during the movement of the strand in the direction of the transport movement around the circumference, until the folding movement is completed.
  • the parabolic section is a section of a second-order parabola.
  • a favorable for the Umschlag movement of the side edge curvature of the contact surface can be achieved, with a fine-tuning can of course be done by the choice of the coefficients of the parabola section defining parabola equation.
  • the abutment surface is shaped such that the parabolic sections of the successive in the direction of the transport movement of the wrapping strip Cut lines, starting from a straight line, go over Operaparabelabsacrificinge in a Endparabelabites.
  • the contact surface is thereby continuously formed in the direction of the transport movement in the cutting line to the actual Umzziehik causing Endparabelabites, whereby the Umschlagung wrinkling of the wrapping strip can be further improved by the side edge of the wrapping strip in this section to the Endparabelabrough already before the actual Turning already on the strand is moved.
  • the beginning of the parabolic section is arranged on the contact surface at a distance from the format base.
  • the parabolic section therefore does not necessarily have to start directly on the edge of the contact surface which bears against the format base; Instead, one, starting from the format reason, have linear section in the section line.
  • a method for producing a format part according to claim 11 is proposed to solve the problem, wherein the contact surface is made by a machining.
  • the parabolic section can be produced by the machining particularly precisely and also with the aid of a computer-controlled machining.
  • FIG. 1 is a section of a inventively designed strand-making machine with a shaping section 15 can be seen.
  • an endless strand 1 of tobacco or a filter material is fed by a device 16 onto a wrapping strip 12, which in turn rests on a strip 2 transporting the wrapping strip 12 and the strand 1 resting thereon in the direction C.
  • the forming portion 15 serves to wrap the wrapping strip 12 fed in a planar orientation around the strand 1 and fix it in its shape by adhering the side edges of the wrapping strip 12.
  • the strand manufacturing machine corresponds to the prior art and can be assumed to be known.
  • a generic Strangherstellmaschine is eg from the DE 36 24 098 A1 in which the shaping section 15 described here is designated as "format”.
  • format the shaping section 15 described here is designated as "format”.
  • the shaping portion 15 is along the cutting directions AA and BB in the FIGS. 2 and 3 enlarged to recognize.
  • the shaping section 15 is called by a Formatground 3, or also called Formatuntererteil, and two resting on the Formatgrin 3 format parts 6 and 7, also called format tops or cover parts formed.
  • the Formatground 3 has a channel 4 with a in the direction C of the transport movement of the strand 1 and the wrapping strip 12 is continuously decreasing radius. The channel 4 is thereby recessed in the direction C of the transport movement, starting from a surface of the format base 3 that is flat on the inlet side of the forming section 15, to a semicircular final shape on the outlet side of the forming section 15.
  • the depth of the channel 4 can increase or decrease continuously only steadily increase over a section of the format reason 3 and then remain constant.
  • the strand 1 is encompassed by the shape of the trough 4 at the lower half by the wrapping strip 12 with the side edges of the wrapping strip 12 being turned up the side of the strand.
  • One of the side edges of the wrapping strip 12 is provided with a glue trace prior to entry into the forming section 15 and preferably prior to loading onto the format strip 2 by means not shown.
  • the format parts 6 and 7 each have a contact surface 11 and 17 on which one of the side edges of the wrapping strip 12 laterally comes to rest during the transport movement.
  • the contact surfaces 11 and 17 are shaped such that the side edges of the wrapping strip 12 are successively wrapped around the strand 1 and so far superimposed be that they are glued together by means of the one side edge provided glue trace. For example, in the sectional view in FIG. 2 to recognize how the right in the direction C of the transport movement side edge of the wrapping strip 12 by the contact with the contact surface 17 of the format part 6 during the transport movement, due to the shape of the contact surface 17, has already been wrapped around the strand 1.
  • the contact surface 17 has a continuously changing in the direction C of the transport movement curvature and extent to the opposite format part 7, so that the beating around the strand 1 in the form of a gentle folding movement of the wrapping strip 12 takes place.
  • the contact surface 11 on the format part 7 is still provided in this cross section of the shaping section 15 as a straight line or with a very small pre-curvature, so that the adjoining side edge of the wrapping strip 12 is still in the raised orientation.
  • the contact surface 17 with respect to the format part 7 and the contact surface 11 so that the opposite, left side edge of the wrapping strip 12 by the contact with the contact surface 11 due to their shape on the folded, right
  • the page margin is changed, as in the in the FIG. 3 cross section shown is the case.
  • the format tape 2 causes only the movement of the wrapping strip 12 with the strand 1 arranged therein in the direction C of the transport movement, so that its side edges are not handled with and instead on the format parts 6 and 7 in or on corresponding guides in the U-shaped Be guided alignment.
  • the shape of the contact surface 11 will be described with reference to the section lines 20,21,22,23,24,25 and 26.
  • the cutting lines 20,21,22,23,24,25 and 26 result in each case by a section of the contact surface 11 with a to the direction C of the transport movement, which corresponds to the direction of movement of the wrapping strip 12 and the strand 1, vertical plane.
  • the line of intersection 20 on the entry side of the format part 7 is a straight line, so that the side edge of the wrapping strip 12 comes into contact with the contact surface 11 on entry into the shaping channel of the shaping section 15 delimited by the format part 6 in a plane vertical upright orientation.
  • the contact surface 11 is formed in a first portion 13 such that the cutting lines 21,22,23 are formed teilparabelförmig, wherein the curvature of the direction of C in the transport movement successive cutting lines 21,22,23 is greater until the contact surface 11 in the section line 24 finally has the shape of a final parabola section 10, which is identical in shape in the section lines 25 and 26 of the contact surface 11 along the further transport movement.
  • the final parabola section 10 can thereby be regarded as the parabolic section, which in the section 14 of the contact surface 11 is the final one Envelope movement causes.
  • the proposed shape of the contact surface 11 has been found to be advantageous for a particularly gentle envelope movement of the side edge of the wrapping strip 12.
  • the proportion of the circular arc section 9 at the cutting line 26 on the outlet side can be made larger or smaller from the shaping channel defined by the format part 7.
  • the cutting line 26 may also be formed exclusively by the circular arc section 9.
