  • the products are transferred to a removal device such that each product at most partially overlaps the product previously transferred, with the leading edges of the products being spaced from each other.
  • the products are directly accessible for further processing. If a gripper of the gripper conveyor is not equipped with the correct number of products or incorrect products, this can lead to problems during further processing, for example by not supplying the correct number of products or incorrect products to a further processing station.

  • each of the staples In order to check whether each of the staples is loaded with a first product and a second product, the products held together by a staple are added to the staple Passing by at a control point subjected to an optical-electronic control.
  • a picture of the identification information of the two products is recorded with a stationary image pickup device, the recorded image is processed electronically and the result of the electronic processing is further processed into control signals.
  • the inventive method works without contact, the risk of damage to the products is avoided.
  • the optical-electronic control allows very high processing speeds. Furthermore, the cost of the control according to the inventive method is low, since the corresponding device does not have to have any moving parts. Furthermore, the method according to the invention makes it possible to check whether each of the clamps is fitted with two correct products, which enables reliable, correct further processing or alarming and discharge of incorrect products.

  • This mode is suitable both for the case in which a first printed product 20 and a second printed product 22 should be transported with the same identification information 30, 30 'held by a clamp 12, as well as in the case where the first printed product 20 and the second Printed product 22 different identification information 30, 30 'have.
  • the processing unit 40 responsive to trigger pulses T delayed, generates the capture commands for the imaging device 38.

If this receives a trigger signal T, it gives, as a function of the conveying speed v and the nominal distance B between the leading edges 24, 24 'of the first and second print products 20, 22 - a first time window and then a second time window, within which the comparison unit 46 compares the recorded images with the calibration image E.
