Abstract

The invention relates to a method for assembling a stack ( 10 ) consisting of single or multilayered pre-products ( 1115 ) of equal or different sizes, said pre-products lying freely one on top of the other, wherein the stack ( 10 ) has two outer pre-products ( 11, 15 ). According to the method, the stack ( 10 ) is given a cohesion that facilitates later handling. The cohesion is achieved in a very simple and flexibly applicable manner by providing the slack ( 10 ) to be assembled in a first step, said stack consisting of pre-products ( 11 - 15 ) that lie freely one on top of the other, and by attaching at least one connecting element ( 17 ) to an edge ( 16 ) of the stack ( 10 ) in a second step such that said element overlaps the two outer pre-products ( 11, 15 ) of the stack ( 10 ) in a clamping manner.

First claim

The invention claimed is:

1. A method for assembling a stack ( 10 , 10 ′, 10 ″; 32 ) consisting of single-layered or multi-layered pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) that lie freely one on top of the 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 the same or a different size, which stack ( 10 , 10 ′, 10 ″; 32 ) or which collection has two pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) lying on the outside, during which method the stack ( 10 , 10 ′, 10 ″) or the collection is given a cohesion that facilitates the subsequent handling, comprising the steps of:
preparing in a first step the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) associated with the stack or with the collection, and
mounting in a second step at least one connecting element ( 17 ; 17 a , 17 b ; 17 ′; 17 ″; 19 ; 21 ; 49 a , 49 b ) in such a manner that it overlaps the two outside pre-products ( 11 , 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection in an adhesive manner, and
the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection each have at least one preferred edge, in that the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection are arranged and aligned in the stack ( 10 , 10 ′, 10 ″; 32 ) or in the collection in such a manner that the preferred edges of the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) together form at least one stack edge ( 16 ), and in that said stack edge ( 16 ) is used for mounting the at least one connecting element ( 17 ; 17 a , 17 b ; 17 ′; 17 ″; 19 ; 21 ; 49 a , 49 b ), and
wherein such edges at which the pre-products are folded and/or stitched and/or glued are taken as the preferred edges of the two pre-products laying on the outside ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″), and
wherein in the first step the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) associated with the stack or with the collection are prepared in the form of the stack ( 10 , 10 ′, 10 ″) or of the collection, and
wherein placing the pre-products ( 11 - 15 ; 11 ′, 15 ′; 11 ″, 15 ″) one on top of the other or side by side in a predetermined sequence one after the other in a collating apparatus ( 40 , 56 ), for preparing the stack ( 10 , 10 ′, 10 ″; 32 ) to be assembled or the collection to be assembled, and
wherein in the application apparatus ( 46 ) an adhesive tape ( 20 ) is unrolled from an adhesive tape roll ( 51 ), an adhesive strip ( 17 ) is cut off the unrolled adhesive tape ( 20 ) and the cut adhesive strip ( 17 ) is mounted on the stack ( 10 , 10 ′) guided past or on the collection guided past, and
wherein the stack ( 10 , 10 ′) or the collection is conveyed through the application apparatus ( 46 ) with the selected stack edge ( 16 ) in front, and in that the cut adhesive strip ( 17 ) is held in readiness at right angles with respect to the conveying direction of the stack ( 10 , 10 ′) or of the collection with one adhesive side oriented against the conveying direction of the stack ( 10 , 10 ′) or the collection in such a manner that the stack ( 10 , 10 ′) or the collection, during its conveying through the application apparatus ( 46 ), contacts the adhesive strip ( 17 ) held in readiness by way of the selected stack edge in the center and entrains it.

2. The method as claimed in claim 1 , wherein at least one connecting element ( 17 ; 17 a , 17 b ; 17 ′; 17 ″; 19 ; 21 ; 49 a , 49 b ) overlaps the two outside pre-products ( 11 , 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection in an adhesive manner in each case on the outside.

3. The method as claimed in claim 1 , wherein at least one connecting element ( 17 ; 17 a , 17 b ; 17 ′; 17 ″; 19 ; 21 ; 49 a , 49 b ) overlaps the two outside pre-products ( 11 , 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection in an adhesive manner in each case on the inside.

4. The method as claimed in claim 1 , wherein several connecting elements ( 17 ; 17 a , 17 b ; 49 a , 49 b ) are mounted longitudinally of the selected stack edge ( 16 ) on the stack ( 10 , 10 ′, 10 ″; 32 ) or on the collection overlapping the two outside pre-products ( 11 , 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′, 10 ″; 32 ) or of the collection.

5. The method as claimed in claim 1 , wherein several connecting elements are mounted on several selected stack edges on the stack or the collection overlapping the two outside pre-products of the stack or of the collection.

6. The method as claimed in claim 1 , wherein the adhesive strip ( 17 ; 17 a , 17 b ; 17 ′; 17 ″; 19 ; 49 a , 49 b ) is elongated.

7. The method as claimed in claim 1 , wherein the adhesive strip ( 17 ″) includes a perforation ( 23 ) in the center when viewed in the longitudinal direction.

8. The method as claimed in claim 1 , wherein to facilitate the separation of the adhesive strip from the adhesive tape ( 20 , 51 ), the adhesive tape ( 20 ) is provided with corresponding notches ( 25 ) or incisions ( 26 ) at the separating points.

9. The method as claimed in claim 1 , wherein the collating apparatus ( 40 , 56 ), the forming stack or the forming collection is guided past a plurality of supplying conveyors ( 43 ) arranged one behind the other, wherein the supplying conveyors ( 43 ) supply at least one pre-product in each case to the stack or the collection.

10. The method as claimed in claim 1 , wherein guide elements ( 55 ), which press the adhesive strip ( 17 ) picked up by the stack ( 10 , 10 ′) or the collection in an overlapping manner against the two outside pre-products ( 11 , 15 ; 11 ′, 15 ′; 11 ″, 15 ″) of the stack ( 10 , 10 ′) or of the collection, are provided in the application apparatus ( 46 ).

11.
