a supply unit having at least two passages for separately supplying an edge strip core and a material strip of a casing for the edge strip core, said material strip being provided with a decorative element; an adapter unit arranged downstream of the supply unit, and a processing unit arranged downstream of the adapter unit,

wherein the supply unit is designed to arrange the edge strip core on a surface side of the material strip, said surface side forming the inner side of the casing, and the adapter unit is designed to fold the material strip around the edge strip core,

wherein free ends of the casing protrude from the edge strip core and lie one above another,

wherein the processing unit connects the free ends lying one above another to one another,

wherein one of the passages is designed as a slot and is provided to guide the casing separately from the edge strip core into the adapter unit.

2. The device as claimed in claim 1 , wherein one of the passages is designed as an opening and is provided to guide the edge strip core separately from the casing into the adapter unit.

3. The device as claimed in claim 1 , wherein the adapter unit is connected to the supply unit in an integrally bonded, force-fitting and/or form-fitting manner.

4. The device as claimed in claim 1 , wherein the adapter unit is in the form of a folding unit and is designed to place the free ends of the casing one above another.

5. The device as claimed in claim 1 , wherein the adapter unit comprises at least one upper guide in the region of the passage of the supply unit.

6. The device as claimed in claim 1 , wherein the adapter unit comprises at least one lower guide in the region of the passage.

7. The device as claimed in claim 1 , wherein the processing unit is in the form of a sewing machine and is designed to sew the free ends of the casing to one another.
