The invention relates to a method and a system for assembling multilayer wafers made of individual waffle sheets provided with layers of cream and one uncoated wafer sheet.

Usually such cream wafers are made in such a way that those made in a baking machine Wafer sheets stacked, optionally cooled and then fed to a spraying device will. In this, the sheets are placed next to one another by hand on a conveyor that carries them through the sprayer passes through, in which its upper surface is covered with a layer of cream or a other filling, such as caramel, chocolate or jam, is provided. The ones from the The sheets that come out of the device and provided with the layer are then manually cut into the desired Number superimposed and covered on top with an unlayered sheet. The blocks thus formed are then stacked, pressed together and, after cooling, a Cutting machine fed, in which they are longitudinally and transversely into small pieces of the desired dimensions be cut up.

This process requires a lot of manual labor. The invention has set itself the task of a method and an automatically operating system for the production of multi-layered cream wafers individually from the Baking machine to create wafer sheets, where during normal work up to When the wafers exit, no manipulation is required for packaging. You can also use the system connect another packaging machine so that this operation can also take place automatically.

A machine for the production of filled wafers is already known, in which on the wafer sheets a layer of cream as they pass a container containing a filling compound is applied. To avoid moving or breaking the thin wafer sheets through the underneath To prevent the filling compound from escaping from the container with strong pressure, the waffle containers are used when Application of the filling compound held by air pressure on its base. After applying the Filling compound, an uncoated wafer sheet is to be placed by hand on the coated wafer sheet.

Furthermore, a stacking device for wafers is known, which is located between the outlet end of a filling compound application device and a downstream cooling device is to be arranged. Behind the conveyor belt for the coated wafer sheets are two arresting rails attached to swivel arms are arranged through a circumferential Method and system for assembling multilayer wafers

Cam are controlled so that waffle blocks from one for entry into the cooling device adjustable number of coated wafer sheets can be put together. Placing an uncoated Wafer sheet on the wafer block then takes place outside of the stacking device, but also by hand.

After all, it was known to produce two coherent wafer sheets in a baking machine To apply a layer of cream to two such wafer sheets, the double wafer band between pressure rollers to pass through and then fed to a cutting device. Concerned differently in this regard the invention deals with the automatic production of cream wafers from individual wafer sheets Use of well-known baking machines that continuously produce individual wafer sheets of constant Supply certain size, it allows the plant according to the invention, filled as required Make waffles that have two, three, four or more wafer sheets with layers of cream in between contain.

c) The uniting device lays a number of filled waffles in which the wafer sheets from the baking layered wafer sheets on top of each other and automatically covers them one after the other with a filling compound with one of the. branched wafer sheets off. The so-called application device is fed and the blocks that are then produced are then conveyed further. The wafer blocks to be placed on top of one another can produce waffles with two, three, four or five wafer sheets from each other coming from the baking machine and correspondingly one, two, three or four wafer sheets in front of the filling compound applicator at equal intervals,
