  • the product 1 can also only with a staple 10 or more than two Staples 10 are held together.
  • the staple 10 is a conventional clip according to Figure 4a, which is a substantially straight staple back 10b and two bent 180 degrees Staple leg 10a has.
  • the staple legs 10a form ends of the staples 10 and are as shown bent inwards so that they are on the inside 4 of the Printed product 1 abut.
  • the staples 10 can also be formed according to Figure 4b and have in this case approximately in the middle an eyelet 10c, on the back 3 and on the outside 5 of the printed product 1 protrudes upward.
  • the staple 10 also has inwardly bent staple legs 10a on. Basically, there are other forms of staples conceivable.
  • the saddle stitcher S has a frame-fixed saddle 8 with a saddle ridge 9.
  • a collection chain 6 is provided, which is an endless link chain is and at certain intervals wing-like carrier 7 has, which take the printed products 1.
  • the saddle stitcher S and the collector chain 6 are just examples for transport or collection devices for forming printed products 1, such as brochures.
  • the transport of Printed products 1 can thus also with other means of transport respectively.
  • a stapler 11 in particular a wire stitching device provided according to the Figures 1 and 2 is arranged so that the printed products. 1 stapled from above.
  • the stapling process is the Printed product 1 between a stapling head, not shown here and a Umbieger.
  • After the formation of the staple form becomes the pierced to stapled printed product 1.
  • the bending of the two staple legs done in a known manner with here not shown leg benders.

  • a threshold 30 is calculated, which below the silence signal is located.
  • a signal "staple detected” and to the threshold 30 a hysteresis value added. This prevents bouncing in the switching point.
  • the named Threshold 30 becomes adaptive to the actual analog signal tracked until a minimum is reached. Is one Minimum found, the threshold 30 is not changed.
  • the signal "staple detected” is reset and the new one Threshold 30 is calculated and tracked based on the sensor signal.
  • the threshold 30 will be the analog signal for so long tracked until the maximum value is reached. After that will the threshold 30 kept constant and to a new fall below or waiting for a new staple 10.
  • the degree of adaptation of threshold 30 may be via two parameters be set. One determines the strength of the adaptation in the off state and the other the adaptation in the on state of Signal "staple detected". Is the sensor signal in the idle state, a fixed offset is subtracted to the rest signal, to calculate the threshold 30.
  • each for each staple generates a digital signal D1 or D2.
