- the dispensing unit 21 and the pressing unit 51 are only indicated schematically and are explained in more detail with reference to the following figures.
- the spacer circulation unit 31 comprises a plurality of support units 45, with spacers 41, 42 in the form of spacer or support panels, which are moved circumferentially along a closed orbit U in the transport direction T.
- the support units 45 are each deflected around a first and a second deflection 75, 76.
- the application section A is arranged between the two deflections 75, 76.
- the support units 45 are moved along the application path A in the same direction as the printed products 1.
- the support units 45 are each connected to a conveying element 34 by means of which they are driven in a revolving manner.
- the support units 45 each include a front spacer 42 and a rear spacer 41 viewed along the application path A in the conveying direction F.
- the front spacer 42 forms the trailing spacer of the leading printed product 1
- the rear spacer 41 forms the leading spacer of the trailing printed product 1.
- the Spacers 41, 42 are pivoted laterally between the printed products 1 in front of the delivery unit 21 at the beginning of the application section A, ie viewed in the conveying direction F.
- the spacers 41, 42 are pivoted laterally from bottom to top between the printed products. That is, the spacers 41, 42 are pivoted with their long sides from a horizontal position into a vertical position between the printed products.
- a receiving gap 44 for a printed product 1 is formed between each of the support units 45.
- printed products 1 are conveyed into the application section A while hanging. Furthermore, support units 45 from a first deflector 75 are moved into the application path A in synchronism with the printed products 1. The support units 45 are each arranged laterally offset to the printed products 1 and are aligned with the spaces between the printed products 1.
- the spacers 41, 42 are pivoted from a passive position outside the conveying space of the printed products 1 into a functional position between the printed products 1, in such a way that a leading and trailing spacer 41, 42 is assigned to each of the printed products 1 along the application path A.
- the printed products 1 are guided along the application path A past an adhesive tape dispenser 21 for dispensing adhesive tape sections 10.
- the adhesive strip dispenser 21 comprises a dispenser head 22, of which the adhesive strip sections 10 are applied with a first connecting section 8.1 in the area of a free edge 4 opposite the held edge 3 to the leading outer side 2.1.
- the edge 4 held is the collar or the folded edge
- the opposite free edge 3 is the flower or the open edge.
- FIG. 7 shows an adhesive strip dispenser 21 with a pivotable dispenser head 22.
- the adhesive strip dispenser 21 separates from an adhesive strip tape 9, which is e.g. B. is unwound from a roll of adhesive tape, individual adhesive tape sections 10 and provides them for application to the printed products 1 on the dispenser head 22 ready.
- the adhesive tape section 10 with a first connecting section 8.1 protrude beyond the dispenser head 22 so that the first connecting section 8.1 can be brought into direct contact with the leading outside 2.1 of the printed product 1 conveyed past.
- the dispenser head 22 can be pivoted between an application position and a passive position.
- the dispenser head 22 protrudes into the conveying space of the printed products 1. So that the dispenser head 22 is not pushed away from the leading spacer 41 in the application position, the prior to running spacer 41 has a window-shaped recess 43.
- the dispenser head 22 is with the ready-to-dispense adhesive tape portion 10 during the
- the dispenser head 22 with the ready-to-dispense adhesive strip section 10 hits the leading outer side 2.1 of the printed product 1, whereby the adhesive strip section 10 with its first connecting section 8.1, its
- Adhesive surface to the printed product 1 is executed, is pressed against the leading outside 2.1 of the printed product 1.

- the dispenser head 22 is pivoted downward into an area outside the conveying space of the printed products 1 or the trailing spacers 42 into the passive position by the conveying pressure of the printed product 1 conveyed past and the trailing spacer 42.
- the dispenser head 22 interacts with a restoring element 23 in the form of a leg spring, which ensures that the dispenser head 22 automatically moves into its application position after it has passed the trailing spacer 42 swings back. Furthermore, a new adhesive strip section 10 is provided on the dispenser head 22, so that the adhesive strip dispenser 21 is ready again for the application of an adhesive strip section 10 to the subsequent printed product 1.
- the pressing unit 51 has two functions.
- a first function includes bending over the edge of the adhesive strip section 10 around the free edge 4 of the printed product 1.
- a second function includes pressing a second connecting section 8.2 of the bent adhesive strip section 10 onto the trailing second outside 2.2 of the printed product 1. Folding over and pressing the adhesive strip sections 10 on the second outer side 2.2 of the printed product 1 is shown in more detail with reference to FIGS. 9 and 10a to 10d.
- the width b of the receiving gap 44 is reduced along the application path A in the conveying direction F.
- the support units 45 move closer together along the application path.
- the printed products 1 initially moving in a fanned-out form into the application section A are compacted, in particular towards their open edge 4. This simplifies the application of the adhesive strip section 10 and the sealing of the printed products 1. Following the application of the adhesive strip section 10 and sealing of the printed product 1, the original distance between the support units 45 is restored. This means that the distance between the support units 45 and, accordingly, the width b is increased again.
- the support units 45 can be moved individually along the application path A.
- the change in the width b or the distance between the support units 45 can take place via link guides.

- the second connecting section 8.2. the adhesive strip sections 10 are directed downwards hanging freely.
- the pressing rotary 51 arranged below the printed products 1 conveyed past is driven about its axis of rotation D2, so that the pressing rollers 52 arranged on the holding arms 54 move around the rotary axis D2.
- the pressure rollers 52 move in synchronism with the printed products 1 and below them in the area of the application path A.
- the pressure rollers 52 have a movement component in the conveying direction F in the movement section in the area of the application path A.
- the pressure rollers 52 move in the area of the application path A at a variable speed in the conveying direction F.
- the pressure rollers 52 in the area of the application path A engage from below into the conveying space of the printed products 1.
- a printed product 1 moved to the pressing rotary run 51 now runs with its lower end section, which comprises the free edge 4, onto a pressing roller 52 assigned to this and engaging from below into the conveying space.
- the printed product 1 is conveyed onward via the pressure roller 52, which moves more slowly in the conveying direction F.
- the second one is freely hanging Connecting section 8.2 of the adhesive strip section 10 is captured by the pressure roller 52, ie it is carried along and bent around the open edge 4 across the edges and pressed against the trailing second outer side 2.2 of the printed product 1.
- the leading spacer 41 acts as a counter-holder, which prevents the printed product 1 from evading the contact pressure exerted by the pressure roller 52 on the trailing outer side 2.2 in the conveying direction F.
- the pressure roller 52 is passed below the free edge 4 and rolls upwards on the trailing second outer side 2.2.
- the trailing spacer 42 is swiveled out of the space between the printed products 1 again beforehand, so that the pressure roller 52 with the second connecting section 8.2. in contact with the trailing outside 2.2. can kick. This means that the leading and trailing spacers 41, 42 are pivoted out of the space between the printed products 1 again independently of one another.
- the above-described course of movement of the pressure rollers 52 for bending and pressing the adhesive strip section 10 is predetermined on the one hand by the circumferential movement of the pressure rollers 52 around the rotary axis D2 of the base body 55 and by a pivoting movement of the holding arms 54 about the pivot axis Dl superimposed on this.
- the rolling of the pressure rollers 52 on the trailing outer side 2.2. of the printed product 1 caused by a pivoting movement of the corresponding holding arm 54.
- the pivoting movement of the holding arms 54 takes place in particular via a link guide.
- the functional principle described above for folding over and pressing on the adhesive strip sections 10 is not limited to a specific design of a pressure roller or a rotatably mounted pressure brush. After passing the pressure unit 51, the printed products 1 are closed along their free edge 4.
- the leading spacers 41 are also moved out of the space between the printed products 1 into their passive position outside the conveying space of the
