  • the use of a dedicated motor to drive the displaceable folding cylinder enables it to decouple its movement from vibrations caused in the folder by variably loaded other rotationally driven parts such as a cutting or puncturing roller.
  • Another advantage of using the dedicated engine is that, unlike a common drive of folding cylinder and jaw cylinder by tooth engagement, by suitable control of this motor, the phase angle of the folding cylinder relative to the cooperating with him jaw cylinder is easily changed.
  • a coupling of the rotation of the motor to the width of the jaw gap can be provided such that a folding blade of the folding cylinder engages centrally in each width of the jaw gap in this.
  • the folder is thereby very easy and quickly adaptable to the processing of signatures of different thicknesses.
  • Another advantage is that the assembly with a second transverse fold has no significant effect on the design of the basic unit of the folder d. h., That the usual bearing holes and necessary for the gear drive oil space omitted and do not require an increase in the racks of the folder.
  • the folder further comprises a stationarily mounted folding cylinder.

  • the coupling of the movement of the pivotable jaw 13 to the rotation of the jaw cylinder 9 takes place by means of a in the Fig. 1 not shown cam.
  • This opens the gap of the first jaw 11 shortly before it reaches the gap 8, so that a folding blade mounted on the first folding blade 7 during the passage through the gap of the first jaw 11, the signature carried by the first folding blade 7 signature in the gap of the first jaw 11 can push into it.
  • This creates a first, central transverse fold on the signature.

In the same manner as those of the holding devices and the folding blades are placed, according to the format length equidistant from the holding devices , The smaller the number of holding devices or Folding blade, the smaller the design of the second folding blade cylinder can be performed. In the least case, a holding device and 1 folding blade can be present.

Also, the distance between the first and second jaw 11 and 23 is adjustable.
  • the folding blade 22 pushes the signature 16 in the open gap of the jaw 23 and the signature 16 is clamped in the gap. At the same time, the gripper 21 releases the first transverse fold of the signature 16.

As in Fig. 3 can be seen, they serve to pivot the two legs of the now double-folded signature 16 against the surface of the jaw cylinder 9 and so to complete the folding process that is 26 after folding through the gap between the guide brushes 24 and the jaw cylinder 9 finished product in Fig. 2 to recognize

  • This maximum distance is expediently set to a value which, with slight play, corresponds to the expected thickness of the single transverse folded signature 16. If, in the case of a Textilstopfers the thickness of the signature 16 is greater, and the roller 41 is pressed over the predetermined by the threaded pin 43 degree up, thereby the entire assembly from the working position pivoted upward, and damage to the sensitive moving parts of Jaw cylinder 9 and second folding blade 19 is avoided.

Due to its rotatability, the roller 41 exerts a significantly lower friction on a continuous signature 16 than would be the case with a stationary guide plate such as the guide plate 14. Therefore, at the moment the transfer of the first transverse fold to the gripper 21 of the second folding blade cylinder 19 at most low braking frictional forces act on the signature 16, which simplifies the transfer and improves its accuracy

  • the design of the Fig. 9 thus, optionally, depending on the position of the second folding blade 19, the generation of a second transverse fold or a second longitudinal fold on the product 26th
  • a further development not shown in a separate figure comprises both the pivotable third guide plate 34 Fig. 4 and the tape guide system 91 Fig. 9 ,
  • the movement of the rollers 92; 93 coupled to both the pivoting movement of the folding blade 19 and the movement of the third guide plate 34.
  • This coupling causes when the second folding blade 19 is in its inactivity position, either the guide plate 34 can be folded against the jaw cylinder 9, as in Fig. 4 represented, or the tape guide system 91 engages in the intermediate space 95.
  • the production is thus possible either with a simple transverse fold, with a double transverse fold or with a simple transverse and second longitudinal fold.
