  • the products 14 can be prepared in this form in a drum-like inserting or packaging machine, as described in the publications mentioned above.
  • the products 14 are transported individually freely on the grippers 13 of the conveyor 10 hanging along a conveyor line 1 1, of which only a short section is shown.
  • the gripper 1 3 can either operate on carriage 12 in a (not shown) rail, or be attached to a along the conveying path 1 1 ⁇ be wegten chain.
  • Conveying devices of this type are known, for example, from EP-Al-168361 2, EP-Al-1042203 or EP-Al-557680.
  • the products 14 are held by the grippers 1 3 so that the open longitudinal side of the once folded cover sheet 21 is at the top and is held closed by the gripper 1 3 respectively.
  • the fold 24 of the cover sheet 21, which preferably runs along a center line of the usually rectangular cover sheet 21, is located at the bottom.
  • the size of the cover sheet 21 is chosen so that it protrudes beyond the inserted printed products 22, 23 on the three open sides and can be closed by pressing the projecting edges together (FIG. 3). Since the products 14 are held in the center by the grippers 13 ( Figure 2), the side portions of the products are freely accessible from the side. Accordingly, 1 1 closing devices 15 and 15 'are arranged on both sides of the conveyor line, which are mutually mirror-symmetrical.
  • the speed of the revolving support element 16 or 16 ' is synchronized with the transport speed of the conveying device 10 in such a way that the closing tools 19, 19' - as in FIG As they circulate, they come into engagement with the sides of the products 14 and eat them by a forceps movement, whereby the open closing tool 19, 19 'initially comprises the edge 21 a, 21 b of the product 14 at the beginning of the distance of the joint movement , then performs (in the middle of the distance) a pincer movement and reopens at the end of the distance to release the product 14 closed by the closure 20.
  • the closing tool 19, 19 ' has the configuration shown in FIG. 4:
  • Two clamping jaws 25, 26 are pivotable relative to each other about a common pivot axis 29 in the manner of a hinge.

  • At the clamping jaws 25, 26 are mutually opposite raised perforation elements 30, for example in the form of bent out of the jaw plane tabs, and corresponding openings 31 are arranged.
  • the closure 20 is attached only locally, i. limited to a short portion of the edge, because he should only prevent slipping or falling out of the printed products 22, 23 from the folded cover sheet 21. As a result, the clamping force required in the closing tool 19, 19 'is reduced.
  • a closure 20 can also be attached to the upper longitudinal side, so that the cover sheet 21 is then closed on all sides.
  • additional closing devices can be arranged above the conveying device 10, which correspond to the closing devices 15, 15 '.

  • a conveying device 32 is provided, which grips and holds the products 14 by means of grippers 13 and transports them along a conveying path 11.
  • the products 14 are in this case, however, on a support surface and form a scale flow of partially overlapping products 14. Due to the partial overlap in the scale flow the freely accessible side regions of the products 14 are greatly shortened, whereby the use of appropriate closing tools is difficult.
  • the conveyor line 1 1 as shown in FIG. 6 is curved at one point arcuate.

  • the clockwise pivoting takes place synchronously with the movement of the products 14 on the conveyor line 1 1.
  • the desired shutter 20 is produced in a purely mechanical manner (clamping, hooking). It then takes a quick swinging back counterclockwise to then participate in subsequent products again the synchronous pivoting movement.
  • a (stationary) closing device 37 can be used which has two counterrotating rotatable elements, namely one (lower) roller 38 and an (upper) closing tool 39 comprises.

  • the closing tool 39 is briefly lowered onto the lower roller 38 and thus generates a pressing pressure which, similar to the closing tool 19 of FIG. 4, can be used to form a purely mechanical shutter 20.
  • the type of closure (caulked or hooked) can be chosen freely.
  • FIG. 8 A further embodiment of the invention is shown in FIG. 8:
