The process or procedure is as follows:

From a broad roller or web 25 (Querfälzelmaterial), the material is retracted transversely to the direction of the book block, assembled and then glued and formed in the further transport in the direction of the book block on vorgeleimten spine. Here, the longitudinal folding principle already used in the molding process, which ensures an absolute parallelism to the book block, is used.

In the FIG. 1 shown Querfälzeleinheit 30 comes in a Buchrückenbeleimaschine used. The unit 30 is structurally designed so that you drive out the run on rails 15 unit 30 in its entirety and can swap with another optional unit. The entire unit can be adjusted in height on the height adjustment 11 to the book block back. This measure depends on the glue application and procedure.

This front position is used for presetting, setup and possible maintenance.

The web 25 is guided over a roller assembly past the marking device 2 and the side knife 10 to the cutting table 7. The feed of the web is ensured by a driven roller 20 with counter-pressure roller, which is, for example, gummed.

The surface of the driven roller 20 is designed to bring the web 25 at a precise feed rate for later cutting. This also applies to the holding process on the web. By the appropriate roller assembly even with the adjustable roll holder 1, the goods voltage is always guaranteed and there is no use of a dancer roller (compensation of lots) necessary.

The cutting unit 7 is adjustable with the cutting table via a rake, and is entered via the calibration of the spine width on the touch screen of Buchrückenbeleimaschine. The adjustment of the cutting unit 7 takes place automatically. About the adjustment 12, the correction factor is then set manually so that the Fälzelstreifen is present in the middle after the transfer to the Fälzeltransport 3. The setting of the web width is done manually and is assembled by the side knife 10 accordingly.

The transfer of the Fälzelstreifens done by the pivoting device 9 on the Fälzeltransport 3. In this case, the transfer takes place through the suction table 104 of the pivoting device 9, which provides the Fälzelstreifen by means of an example. Circular movement in parallel over the lower suction table 40. But there are certainly other directions of movement conceivable.

After the pivoting device 9 is above the advanced web 25 is this with the suction table 104 which is located on the pivoting device. 9 is fixed with vacuum. At the same time, the cutting process takes place on the cutting unit 7.

With the Fälzelstreifen fixed to the suction table 104 of the pivoting device 9 is offset by a semicircular pivoting movement of the Fälzelstreifen on the Fälzeltransport 3.

As soon as the upper suction table 104 of the pivoting device 9 is above the lower suction table 40 of the Fälzeltransports 3, the vacuum is switched and the Fälzelstreifen blown off. This process is automated. At the same time takes the lower suction table 40 by means of vacuum fixing the Fälzelstreifens.

The Fälzeltransport 3 is arranged with a suction table 40 and forcibly guided and circulating flat belt 42, which has two parallel rows of holes executed. These rows of flat belt 42 are congruent with the underlying suction table 40 openings.

These openings serve to fix and transport the ready-made Fälzelstreifens on the glued spine.

It is important to note that before production commences, a crimping strip must be provided in the crimping delivery chamber 60 at the exit opening 48 and a second crimping strip must be provided on the lower suction table 40 of the crimping transport 3.

In the Fälzelbereitstellung chamber 60 is another forcibly guided transport flat belt 44. Now sets the perforated flat belt 42 in motion is transported in the introduction of Fälzelbereitstellung chamber 60, the further transport of the Fälzelstreifens between the two flat belts 42, 44 of the Fälzeltransports 3 Fälzelstreifen to the outlet opening 48. In this case, the parallelism of the Fälzelstreifens is ensured by the exact guidance of the flat belt 42, 44 to the book block.

The Zususpung the Fälzelstreifens on the glued book block back is done, for example, via the photocell 46th

The feed rate of the Fälzeltransports 3 is, for example, synchronized to the machine speed.
