Figs. 1 and 2 each show an inventive Device 10 with a plurality of consecutively arranged holding elements 12 with integrated Bending elements 18. These are in a circumferential direction U moved along a closed orbit and while a receiving station 60 and a happen Delivery point 58. FIGS. 3 and 4 show detailed views of the Area of delivery point 58, but in others Snapshots. In Figs. 1 and 3 are the Bending elements 18 on the leading side 12 a of Retaining elements 12, in Fig. 2 and 4 at the trailing Side 12b of the holding elements 12.

With the exception of the bending element 18 corresponds to the structure and the function of the holding elements 12 in the EP-A first 275 607 illustrated and explained holding elements. Of Further corresponds to the structure and function of Device 10 of the in EP-A 1 275 607 shown and explained device. The following are therefore construction and operation of the invention only explained so far, as is necessary for the understanding of the invention. in the Incidentally, reference is made to the content of EP-A 1 275 607. Also possible in EP-A 1 275 607 Modifications of the device can be used here become.

At the receiving point 60 are supplementary products 22 of a feeder 20 was added. At the Delivery point 58, these are printed products 36 delivered and pressed to this. The printed products 36 are from a conveyor 38, here in the form a gripper conveyor with grippers 40, hanging with in the essential constant distance d in a conveying direction F promoted. The holding elements 12 consist of a Base 14, on which a head part 16 pivotally and the Bending element 18 is arranged linearly displaceable. in the Area of the delivery point 58 protrude the head parts 16 two adjacent retaining elements 12 between the Printed products 36. Moving towards each other is a previously bent by means of the bending element 18 Supplementary product 22 around the edge 36c to be sealed, here the open lower edge (the so-called flower), the Printed product 36 placed and pressed there. This in Circulating direction leading holding element 12 and its Head part 16 acts as a support member 44th

The main body 14 of the holding member 12 has the shape of a essentially L-shaped angle lever which is connected to a Support plate 32 is articulated. The articulation axes 28 lie on a circular orbit 26, whose Center is the axis of rotation X of the support plate 32, and are at about the same distance D to each other. With the first leg 50 of the base body 14 is the Head part 16 pivotally connected about a pivot axis 34. The pivot axis 34 is perpendicular to the direction of rotation U or parallel to the axis of rotation X. The second leg 52nd is provided with a control roller 30, which on a Control cam 56 rolls off. By the control cam 56 is the angle changeable, the first leg 50 relative occupies the radial direction. By the curved Orbit 26 stands out in each case a holding element 12 between two adjacent printed products 36 a. It is located the bending element 18 on the one side 36a and the Headboard 16 on the other side 36b of Printed product 36.

The head part 16 has an approximately trapezoidal shape Cross-section and is with at least one suction member 24th equipped in a first surface 16a of the head part 16 is arranged. One of these opposite second Surface 16b has the function of the support member 44, such as will be explained in more detail below. In the variant according to Figs. 2 and 4 are the rollers of the first and second surfaces reversed. In the second area 16b may be another Suction organ 25 may be arranged. It comes in particular then used when the head parts 16 when recording the Supplementary products 22 are inclined in the direction of rotation U (see Fig. 2). Furthermore, the supplement products 22 takes place with the further suction member 25 in a flat state on the trailing side 36b also to the leading Page 36a of the printed product 36 are pressed, if the bending element 18 is deactivated (see EP-A 1 275 607).

The bending element 18 comprises a leaf-like tongue 18a, by means of a fastener 42 on the first Leg 50 slidable in the longitudinal direction is appropriate. In the embodiment according to FIGS. 1 and 3, the tongue 18a is substantially parallel to leading edge 50a of the leg 50 oriented. As in 2 and 4, the tongue 18a can also at the trailing edge 50 b of the first leg 50 is arranged be. In this case, a suction member 25 comes on the second surface 16 b of the head part 16 is used, wherein the Suction member 24 on the first surface 16a is dispensable. As shown in FIGS. 3 and 6, the fastener is 42 preferably with a drive element 46, here a timing belt, connected and is going through this of the main body 14 shifted. The drive element 46 also serves to transmit a driving force on the rotatable head part 16. In the present case, the bending element 18 and the header 16 therefore synchronously shifted or turned. It is also possible bending element 18 and headboard 16 to drive separately, with the movements then should be coordinated.

The relative to the base body 14 rotatable head portion 16 has the purpose at the receiving station 60 in flat condition added supplement 22 until it reaches the Delivery point 58 in a position to bring in the from the Suction member 24 held first end 22 a of the Supplementary product 22 approximately parallel to the printed product 36 runs. In the present case, the supplementary products 22 from the delivery device 20 tangential to Movement path 26 supplied. The delivery device 20 and the head parts 16 roll against each other, creating a fast and reliable delivery of supplementary products is achieved in flat condition. Previously, the Supplementary products such as one from here cut off supply roll shown and / or of detached a carrier material. Furthermore, one is Supply from a stack or Leporello possible. The Delivery device 20 rotates the severed sections preferably in one for further processing suitable location. In this are the sections of the Supplementary product provided with an adhesive are, preferably in the circumferential direction U in a row. It can provide one or more adhesive areas be. The supplement product consists for example of Paper or plastic, e.g. a transparent one Plastic film. It may be in the area of its crest 22c have a perforation, the subsequent separation facilitated.

At the receiving point 60, the head part 16 is in a position in which it is opposite by about 90 ° (Fig. 1) or in the direction of movement U (FIG. 2) from the main body 14 is bent. A through its first surface 16 a (Fig. 2: second surface 16b) or the corresponding suction member 24, 25 defined receiving plane E is tangent to Trajectory 26. Furthermore, this is the Bending element 18 in a radially inner Rest position, in which its leading edge 18b, from the Rotation axis x or seen from the Anlenkungsachse 28, lies in or in front of the recording plane E. Retaining element 12th or suction member 24 can thus well on the Suppliers 20 are approached to the Supplement product 22 in flat condition. While the headboard 16 on the way to the delivery point in or is rotated counter to the direction of rotation U, the Bending element 18 radially in a direction R to the outside pushed. Its leading edge 18b is located at the delivery point 58 finally beyond the reception level E. The first Surface 16 a of the head part 16 is made of a substantially tangent to the trajectory 26 extending direction in a direction substantially perpendicular thereto turned. Under the influence of the movements of the Bending element 18 and the head part 16 is the Supplementary product 22 V-shaped bent. At first, that supports Bend element 18, the free end 22 b of the supplementary product 22 only by its front edge 18b and then slides in its further radial movement along this end 22b.

In this case, the free end 22b comes flat on the bending element 18th to the plant. Due to the inherent rigidity of the Supplementary product and the flexibility of the tongue 18a becomes the tongue 18a is slightly pushed away from the first leg 50. The bending element 18 or its acting as a support surface S, on the supplementary product 22 adjoining inner surface closes with the plane E an acute angle. Thus arises between the head part 16 and the bending element 18 is a V-shaped Admission for the supplement 22.

In addition to the simple production has shown Construction has the advantage that the expansion of the Retaining element 12 in the direction of rotation U through the Bending element 18 is not significantly increased. Also for wider supplementary products 22 is the bending element 18 space-saving on one side of the holding element housed and is not in the rest position laterally or not significantly off.

As in the detailed drawing of the delivery area (FIG. 3 or 4) recognizable, the holding elements 12 from below to the suspended promotional printed products 36 introduced. The Distances and conveying speeds are the same chosen that the lower edge 36c at the delivery point 58th in the region of the apex 22c of the supplementary product 22 is positioned. At the delivery point 58 is the Control link 56 shaped so that the first leg 50th and the head parts 16 of two adjacent holding elements 12 be inclined towards each other. In this case, in the case of FIG. 1 and 3, the first surface 16 a of the trailing, still a Supplementary product 22 supporting holding element 12 in parallel and largely congruent to acting as a support member 44 second surface 16b of the leading retaining element 12th oriented. Due to the relative movement of the adjacent Retaining elements 12, the bending element 18, which is located in between, bent, so it too oriented parallel to the surfaces 16a, 16b. The Supplement 22 thus becomes with its original held by the suction head 24 end 22a at the trailing Page 36b and with his on the bending element 18 and indirectly Supported by the support member 44 free end 22 b at the leading side 36a of the printed product 36 pressed and attached there. In the case of Fig. 2 and 4 results the opposite situation, i. the trailing one Retaining element 12 acts as a support element 44.

The supplement product 22 can extend over the entire length extend the edge 36c or only a part thereof. It especially for sealing the open edge here 36c (so-called flower of the printed product) used. The printed products 36 can also be used in this way be that the folded edge 36d or a side edge with a supplement product 22, e.g. to Reinforcement of the folded edge 36 d, for attaching a Hanger, to hide the stitch, to close the open edges against falling out of deposits or as reading protection as an alternative to filming the whole Printed product. In the present case lies the supplementary product 22 full on the printed product 36, the apex 22c can but also spaced from the edge 36c.

The flexure 18 preferably has a rigidity of the supplement 22 adapted elasticity or Flexibility. Its mechanical properties are preferably chosen so that it, as shown by the supplement 22 from an originally parallel to the first leg 50 extending position of the leg 50th is spread, but light and easy during Andrückvorgang can be deformed without much effort. For the Processing of supplementary products of paper or Plastic is the bending element 18 and the tongue 18a preferably made of hardened spring steel and has for example, one from the fastener 42nd measured effective length of 80 mm, a width of 20 mm and a thickness of 0.1 mm. If the spring element 18a from another material, e.g. Plastic, leather, wood, Metal, preferably becomes a similar elasticity selected.

In principle, comes a little or not springy Bending element in question, preferably relative to Retaining member 12 movable, e.g. is pivotable. His Construction and mechanical properties should be like that be chosen that its area when pressing in the Discharge position already parallel to the printed product oriented or by the Andrückvorgang parallel to Printed product is aligned.

The devices shown in Figs. 1-4 go through simple upgrading with the inventive Bending elements 18 from that shown in EP-A 1 275 607 Device forth. The flexures 18 are constructive simple, inexpensive and easy to assemble. The Bending elements 18 may be in the same basic device according to EP-A 1 275 607 in or counter to the direction of rotation be mounted, resulting in different functions result. As drive is the already existing drive used the head part 16.

Fig. 5 shows a further variant of a inventive device, wherein only the range of Delivery point 58 is shown. The holding elements 12 be hanging along this easily in this area concave curved orbit 26 promoted. Your distance D is at the distance d in pockets 48 (see Fig. 6) or on saddles (not shown) standing in the im essentially the same conveying direction F linearly conveyed Printed products 36 adjusted. The construction of the Retaining elements 12 substantially corresponds to that of FIG. 1-4. In contrast to FIGS. 1-4, adjacent ones function Retaining elements 12 at the delivery point 58 are not mutually exclusive as a support element. Therefore, the second leg 52 and the corresponding control block for the relative movement of two adjacent retaining elements 12 not necessarily available. Instead, there is one here Support member 44 at the delivery point 58, the pressing a supplementary product 22 with the head part 16 interacts. The support member 44 is over a part the trajectory 26 moves with the holding elements 24. There may be a plurality of support elements 44. Of Further, the support member 44, as shown in Fig. 6, Be part of the retaining element 12.

As can be seen in the right-hand part of the picture, the head part 16 initially oriented approximately at right angles to the base body 14. The flexure 18 is in its rearward End position. The held supplement product 22 is thus approximately parallel to the direction of movement U of the holding elements 12 and to the conveying direction F of the printed products 36 aligned and is located at a small distance to be sealed Edge 36c of the printed product. By the simultaneous Pivoting movement of the head part 16 about the pivot axis 34 and the bending element 18 perpendicular thereto in the direction R prick headboard 16 and bending element 18 at one Page 36a, 36b of a printed product 36 between adjacent printed products 36. A curved one Orbit 26 as in Fig. 1-4 is therefore not necessary to the supplementary product 36 sufficient to the Approaching printed product 36. The supplement 22 is thus bent around the edge 36 c and on the Delivery point 58 pressed there. The bend is going through supports gravity.

Fig. 6 shows a variant of the apparatus of Fig. 5, at each support element is associated with a support member 44. Here, too, can thus on a relative movement of the Retaining elements 12 and a corresponding control link be waived. The support member 44 is over a Lever 62 connected to the support member 12. It's about that Anlenkachse 28 pivotally, but can also be a be parallel to this pivoting axis. The Support member 44 is preferably used together with the Head part 16 and the bending element 18 driven.

In the grippers 40, bags 46 or saddles the Conveyor 38 for the printed products 36 can instead of a printed product 36 each also several held by a common supplement 22 get connected.

The supplement product 22 is not necessary flat designed. It can also be a three-dimensional object to be attached to the printing product 36 with the Bending element 18 is bent.
