Definitions

  • the invention relates to a device for producing folding products consisting of strand sections, an inner part and an outer part which differs in terms of material, color, etc., with a receiving cylinder which cooperates with the controlled grippers holding the strand sections placed thereon and with the folding jaws of a folding jaw cylinder Folding knives is provided and against which a band guide which feeds the strand sections forming the outer part and which wraps a front peripheral section arranged upstream of the folding jaw cylinder and a band guide which feeds the strand section forming the inner part and which wraps a rear peripheral section upstream of the front circumferential section bears.
  • a device of this type is known from DE-OS 33 02 036.
  • This known arrangement is used only to complete a multi-layer inner part with a single-layer envelope.
  • the front tape guide is accordingly loaded with the envelope-forming sheets, which are collected and collected and fed to the receiving cylinder already containing the inner parts and placed on the package forming the inner part.
  • products with a multilayer outer part are desired.
  • This can be e.g. B. are magazines, the inner sheet of which is designed as a single-colored inner part, for example in the form of a removable insert, such as a radio program etc., and all of the other parts of which form the outer part are of multi-colored design.
  • a collecting cylinder running synchronously with the take-up cylinder is arranged, which is partially wrapped by a belt section of the assigned belt guide and in its place the other belt section of the assigned belt guide is interrupted and is provided with the controlled grippers holding the strand sections fed to it and with the associated controlled lifting levers which can be activated for each number of revolutions of the collecting cylinder corresponding to the number of strand sections deposited on the collecting cylinder in the region of the belt section partially wrapping around them .
  • these measures enable the strand sections forming the outer part and / or the strand sections forming the inner part to be collected. Different types of products can therefore be produced without changing the number of material strands. It is only necessary to change over the gripper or lifting knife or folding knife control and the speed of the cross-sections and the pulling rollers assigned to them from collecting operation to non-collecting operation.
  • the receiving cylinder and the collecting cylinder as well as the two belt guides always run at the same speed, which results in a simple construction effort. Since both the take-up cylinder and the collecting cylinder work together with a tape guide, this advantageously results in a format-variable folder, so that any desired format can also be produced.
  • the receiving cylinder iginate both the receiving cylinder arises due to the distance from the opposite here offset collecting cylinder also a good train g and the collecting cylinder. Since these two cylinders do not interact directly with one another, but are connected to one another via a belt guide, critical crumple zones are advantageously avoided even when stopping.
  • the collecting cylinder which is arranged in the area of the front band guide and is partially wrapped around it, deflects the assigned band guide by approximately 90 °.
  • the respectively assigned strands of material can therefore be fed in parallel and the respectively assigned cutting units offset laterally at approximately the same height, which also has an advantageous effect on the structural effort required.
  • the receiving cylinder and the collecting cylinder can be connected to one another in terms of drive by means of a longitudinal shaft, which results in a particularly simple and reliable drive mechanism.
  • a further advantageous embodiment of the superordinate measures can be characterized in that in the region of the end of the interrupted belt section facing the collecting cylinder of the belt guide assigned to the collecting cylinder there is a stationary guide wedge which has a contact surface oriented approximately tangentially to the circumference of the collecting cylinder and that on the collecting cylinder can be activated when the guide wedge passes by.
  • a stationary guide wedge which has a contact surface oriented approximately tangentially to the circumference of the collecting cylinder and that on the collecting cylinder can be activated when the guide wedge passes by.
  • the band guide assigned to the collecting cylinder can have two successive sections, the collecting cylinder being arranged in the region of the upstream section.
  • the collecting cylinder can be assigned a pressing element which is arranged outside its area wrapped by the assigned band guide and is preferably designed as a pressing band. This ensures that the strand sections received on the collecting cylinder are reliably pressed against the collecting cylinder during collecting operation.
  • the booklet shown in FIG. 1 consists of an inner part 1 made of thin material and an outer part 2 made of comparatively thick material.
  • the inner part 1 and the outer part 2 each consist of two superimposed, arcuate strand sections, which in turn can be single-layer or multi-layer.
  • the arcuate strand sections forming the individual layers of the inner part are successively cut down from one and the same strand of material.
  • two have to be on top of each other the following strand sections are collected.
  • the individual sheet packs of the inner part 1 and the individual sheet packs of the outer part 2 are collected separately from one another, then placed on top of one another and then folded together.
  • the folder suitable for producing such a booklet according to FIG. 2 is provided with two mutually offset tape guides 3 and 4, the downstream ends of which loop around two successive circumferential sections 5 and 6 of a receiving cylinder 7.
  • the band guide 4 which wraps around the rear circumferential section 6 of the receiving cylinder 7 in the direction of rotation of the receiving cylinder 7, the strand sections 1a, 1b forming the inner part 1 are fed to the receiving cylinder 7.
  • the belt guide 3 wrapping around the front circumferential section 5 in the direction of rotation, a complete outer part 2 is fed to the receiving cylinder 7 for each complete inner part 1.
  • the strip guides 3 and 4 are acted upon by a respectively assigned cross cutter 8, each with upstream pull rollers 9, with the strand sections 1a, 1b and 2a, 2b required to form inner parts 1 and outer parts 2, respectively.
  • a strand of material 10 containing them in a sequential order is divided accordingly by means of the assigned cross cutter 8.
  • the strand sections 2a, 2b on the outer part side are cut off from a material strand 11 by means of the associated cross cutter 8.
  • the receiving cylinder 7 is provided with controlled grippers 12 for holding the strand sections placed on it and with controlled folding blades 13 arranged between the grippers for forming a transverse fold.

  • the diameter of the belts 17 of the belt guide 3 associated with the belts of the belt set 3a of the belt guide 3 is somewhat smaller than the diameter of the belts of the belts of the belt circumference 6 which surround the rear circumferential section 6 of the belt guide 4, causing collisions of the belt set 3a with it non-unwinding receiving cylinder 7 are reliably switched off.
  • sheet guides formed by stationary guide tongues are provided here. It would also be conceivable to press the sheet packs in the gusset area onto the receiving cylinder 7 by means of an air stream or the like.
  • the receiving cylinder 7 is designed as a collecting cylinder, ie the folding knives 13 can be controlled so that they are activated only every second pass by the folding jaw cylinder 15.

  • the grippers 20 are also designed as flat single grippers which are controlled to collect the strand sections 2a, 2b on the outer part in such a way that they make the first rotation during a first rotation of the collecting cylinder 19 Detect strand section 2a and, during the subsequent rotation of the collecting cylinder 19, grasp in the area wrapped by the belt set 3b of the belt guide 3, in which the stack sections 2a, 2b lying on top of each other are pressed onto the collecting cylinder 19.
