Definitions

  • the invention relates to an arrangement of rollers in a folder Web rotary printing machine.
  • the invention relates to an arrangement of Rolls for feeding a plurality of printed webs or strands as one multilayered web to form a pair of draw rollers, which are located above a former in one Folder of a web-fed rotary printing press is located.
  • a variety of printed webs or web strands is usually over an appropriate number of merging rollers guided around the strands to be arranged one on top of the other before they form a pair of pulling rollers as a multilayered web are fed, which above a former for the longitudinal folding of the multilayer Path is arranged.
  • the pull rolls include a driven metal roll, usually a steel roller, and a non-driven rubber or urethane roller, which is pressed against the driven metal roller with an adjustable force to the Friction between the layered web and the driven metal roller increases change, thereby regulating the tension of the layered web before this passed the former.
  • the merging rollers and the pulling rollers which are located on top of the former, arranged so that the layered web at an angle to the nip of the Pull rollers is performed. Therefore, the layered web either wraps around both Pull rollers or it wraps around the circumference of one of the pull rollers while it is running other pull roller only touched peripherally.
  • European patent application EP 0 747 312 A1 discloses a folder which has one Arrangement of merging and take-off rollers for feeding at least two Covers webs as a multi-ply web to a feed roller that overlies a former is arranged for folding the layered web.
  • the stratified Web of the feed roller fed at an angle, the feed roller by a single guide roller is formed which is not in contact with any other roller and which therefore no regulation of the web tension possible.
  • US 5,398,604 discloses a pull roll assembly which is a driven, rotatable in one Frame-mounted transport roller and an associated pull roller with a removable Includes sleeve, which is made of elastic material.
  • the press roll is rotatable in pivoted arms mounted and can by means of a pneumatic actuator brought into contact with the conventionally designed driven transport roller become.
  • Another object of the present invention is to prevent the appearance of wrinkles and to eliminate other undesirable irregularities in the printed product, due to the radius effect when transporting a layered, multilayered web caused the nip of a pair of pull rollers that are above one Folding former for longitudinal folding of the layered web is located.
  • a Arrangement of rollers in a folder of a web-fed rotary printing press Variety of merging rollers to run along a variety of incoming strands to move a line that is substantially tangent to the plurality of Merging rollers runs, and thereby form a multi-layer web, and furthermore a first and a second pull roller, both with a coating provided with elastic material and arranged so that the multilayered web through a nip is guided, which is formed between the pull rollers and in is substantially tangent to each of the draw rolls.
  • An advantage of the arrangement of the rollers according to the invention is that they are one precise and safe transport of the layered, multilayered web to and via one subordinate former, which leads to a higher accuracy of Longitudinal fold leads, which is carried out on the layered web when this over the The former is guided.
  • the strands 2a, 2b, 2c, 2d are e.g. B. with different images in associated (not shown) printing units printed, the folder seen in the direction of the strands 2a, 2b, 2c, 2d are connected upstream.
  • the guide rollers 4a, 4b, 4c, 4d are preferably non-driven guide rollers, as they are known from conventional folders and used in them.
  • the merging rollers 4a, 4b, 4c, 4d can also be rollers of one or more electric motors (not shown) individually or in pairs are driven.
  • the merging rollers 4a, 4b, 4c, 4d preferably consist of an inelastic material, for example steel or aluminum, can also with a layer of elastic material, such as rubber or urethane, be covered.
  • the merging rollers 4a, 4b, 4c, 4d are like this arranged that each of the strands 2a, 2b, 2c, 2d is guided along a line 6 which in Fig. 1 is indicated by dashed lines and which is substantially tangential to the Merging rollers 4a, 4b, 4c, 4d runs.
  • they are Guide rollers 4a, 4b, 4c, 4d aligned so that the circumferential lines 8a, 8b, 8c, 8d, where the strands 2a, 2b, 2c, 2d each make contact with the associated one Lose guide roller 4a, 4b, 4c, 4d, essentially along line 6 are arranged which are substantially tangential to each of the merging rollers 4a, 4b, 4c, 4d extends so that the multilayer web 2 essentially along the Line of contact 6 runs.
  • the first pull roller 12 and the second pull roller 14 are like this arranged that the line of contact 6 is substantially in the middle of the gap 10th located and a line 16 through the centers of the first draw roller 12 and second pull roller 14 runs, is substantially perpendicular to the line of contact 6.
  • the pull rollers 12, 14 are arranged in such a way that the multi-layer Web 2 runs tangentially to the first and second pull rollers 12, 14 without to wrap around the circumference of one of the pull rollers 12, 14 when the web 2 passes through the Middle of the nip 12 is transported.
  • the first pull roller 12 is a driven roller with a core or body 18 which is connected to a covering 20 made of elastic material, such as rubber or urethane, is provided.
  • the coating or covering 20 is preferably made by an endless Formed sleeve with adhesive or by means of a schematically indicated Notch connection 22 can be connected to the core 18.
  • the second pull roller 14 is preferably of the same design as the first Pull roller 12 and has a core or body 24 of inelastic material, preferably Steel or aluminum, and a covering or coating 26 made of elastic Material bonded to the body 24 with adhesive or a notch 22 connected is.
  • the coating 26 of the second pull roller 14 also preferably consists of a continuous rubber or polyurethane sleeve.
  • the second draw roller 14 is one non-driven roller which is rotatably supported in pivotable arms 28.
  • the pivotable arms 28 may be by means of a known actuator, for example a pneumatic cylinder 32 to be rotated about an axis 30 to the second Pull roller 14 in and out of contact with the first pull roller 12.
  • a pneumatic cylinder 32 to be rotated about an axis 30 to the second Pull roller 14 in and out of contact with the first pull roller 12.
  • first and second pull rollers 12, 14 and the straight and symmetrical transport of the layered web 2 through the nip 10 are all superimposed strands 2a, 2b, 2c, 2d, which form the layered web 2, with transported through the nip 10 at substantially the same speed.
  • the symmetrical deformation of the elastic coatings 20 ensures and 26 of the first and second pull rolls 12, 14 for a substantially constant one Surface speed of the two coatings 20, 26 in total Contact area 34a, 34b, in which the coatings 20, 26 each in contact with the multilayer web 2 are.
  • the multilayer web 2 After the multilayer web 2 has passed the nip 10, it becomes one conventional former 36 and a further pair of pull rollers 40 out for longitudinally folding the web 2 under the former 36.
  • the first and second pull rollers 12, 14 are preferably on top of the Folder 36 arranged, the arrangement of the first and the second Pull roller 12, 14 is preferably placed over the former 36 so that the multilayer Web 2 the nip 10 tangent to the two pull rollers 12, 14 and in leaves essentially tangential to the upper plane 38 of the former 36.
  • the Merging rollers 4a, 4b, 4c, 4d, the first and second pull rollers 12, 14 and Upper level 38 of the former 36 are preferably arranged so that the multilayer Path 2 moves along the line of contact 6, certain angular deviations be acceptable from the line of contact. This depends on the specific application and the execution of the folder. For example, the angle at which the multilayer web 2 in the nip 10 between the first and the second Pull roller 12, 14 enters from the direction of the line of contact 6 e.g. deviate by ⁇ 3 °. In the same way, the angle between the web 2, which leaves the nip 10, and the line of contact 6 and / or between the line of contact 6 and the upper one The plane 38 of the former 36 also moves in a range of approximately ⁇ 3 °.
