Method for assembling a stack or a collection consisting of single or multilayered pre-products that lie freely one on top of the other, compositions of such pre-products, and applicator for producing such compositions

An applicator (46) for producing a composition in the form of a stack or a collection including single-layered or multi-layered pre-products (11-15;

• 11′, 15′;
• 11″, 15″), in a stack, that lie freely one on top of an other or a collection consisting of single-layered or multi-layered pre-products (11-15;
• 11′, 15′;
• 11″, 15″) that lie freely side by side of a same or a different size, the stack (10, 10′, 10″;
• 32) or the collection having two pre-products (11, 15;
• 11′, 15′;
• 11″, 15″) each lying on an outside, wherein the applicator (46) comprises:
• two parallel conveying belts defining a conveying path there between for the composition, each of the belts acting on one of opposing outside side faces of the composition;
• at least two pressing flanks (55) each acting on one of the outside side faces of the composition (10, 10′, 10″;
• 32) in a non-positive manner;
• and
• a free region between the pressing flanks (55);
• wherein the applicator (46) is adapted to apply at least one adhesive strip (17;
• 17a, 17b) as the composition is moved with a relative speed by the belts between the pressing flanks, the free region during the application corresponds at least approximately to a height of the composition (10, 10′, 10″;
• 32), and the pressing flanks include lateral pressing faces (55) or rolling faces to apply at least one connecting element (17;
• 17a, 17b;
• 17′;
• 17″;
• 19;
• 21;
• 49a, 49b) on the composition to achieve a cohesion of the pre-products to facilitate a subsequent handling, wherein the at least one connecting element (17;
• 17a, 17b;
• 17′;
• 17″;
• 19;
• 21;
• 49a, 49b) overlaps the outside two pre-products (11, 15;
• 11′, 15′;
• 11″, 15″) of the composition in an adhesive manner.
