Abstract

Dispensers, systems and methods dispense strips of a first adhesive tape which have adhesive on both sides and on one side is covered with a liner. A first storage unit from which the first adhesive tape is drawn off is provided, and a second storage unit from which a second adhesive tape is drawn off is provided. A connection installation by means of which the first adhesive tape and the second adhesive tape are interconnected so as to form a two-ply adhesive tape is provided, and an application installation by means of which the two-ply adhesive tape as a composite is capable of being applied to a substrate is provided.

First claim

The invention claimed is:

1. A dispenser configured for dispensing a strip of a first adhesive tape that is adhesive on both sides and on one side is covered with a liner, the dispenser comprising:
a first storage unit from which the first adhesive tape is drawn off;
a second storage unit from which a second adhesive tape is drawn off;
a connection installation by means of which the first adhesive tape and the second adhesive tape are interconnected to form a two-ply adhesive tape;
an application installation by means of which the two-ply adhesive tape as a composite is capable of being applied to a substrate; and
a storage roll that is capable of being driven by a drive installation that is synchronized with the drawing-off movement of the first adhesive tape, of the second adhesive tape, or the two-ply adhesive tape is provided, wherein
the liner which has been drawn off from the two-ply adhesive tape is wound onto said storage roll.

2. The dispenser according to claim 1 , further comprising:
a third storage unit from which a functional layer, which is capable of being incorporated between the first adhesive tape and the second adhesive tape.

3. The dispenser according to claim 1 , wherein
the drive installation has a drive wheel with a rotating motion which is driven by a drawing-off movement of the first adhesive tape, the second adhesive tape, or the two-ply adhesive tape, the rotating motion of said drive wheel being transmitted to the storage roll by means of a gear.

4. The dispenser according to claim 1 , further comprising:
a cutting installation in which the two-ply adhesive tape having the liner disposed thereon, prior to being applied to the substrate, is cut in a dual-stage cutting process wherein,
the two-ply adhesive tape including the liner disposed thereon is cut off in a first cutting step, and
only the two-ply adhesive tape is cut off in a second cutting step.

5. The dispenser according to claim 1 , further comprising:
an adhesive tape accumulator by way of which the first adhesive tape and the second adhesive tape are guided after having been connected to form the two-ply adhesive tape and prior to being applied to the substrate.

6. The dispenser according to claim 5 , wherein
the adhesive tape accumulator is formed by a chicane that intentionally increases a running length between the connection installation and the application installation or by a second storage roll.

7. The dispenser according to claim 1 , further comprising:
a timer which displays the time span between connecting the two adhesive tapes and applying the two-lay adhesive tape.
