ABSTRACT:
The process makes it possible to gather together and detachably connect two or more partial products (2a, 2b). The resulting end product can be broken down again into partial products without destroying them. The connection between the partial products is of variable intensity. An apparatus for performing the process has a collecting mechanism (20), a supply (10) for an outer partial product (2a) and a supply for an inner partial product (2b), an opening station (21), a straightening station (23), a removal station and an adhering station (22), which is connected upstream of the supply point (11) at which the two partial products (2a, 2b) are brought together, as well as a pressing station (24). The adhering station (22) is connected to an adhesive supply and control unit (35), which makes it possible to adjust the adhesive quantity vary the surface areas and location where adhesive is applied.
