Abstract
Abstract An apparatus for joining two single adhesive tapes, each provided with an adhesive layer on one side, to form a double sided adhesive tape with two supports each rotatably mounting a tape roll on a frame in mutually corresponding radial planes. The tapes pass around tape controls where they are joined together.

Claim 1
Independent Claim
221 words
A device for joining two adhesive tapes each having one adhesive side into a centrally overlapping double adhesive tape with the adhesive sides on either side of the overlapping area facing in opposite directions comprising: two supports for each rotatably mounting one supply roll of rolled-up single adhesive tape around a rotary core; a frame mounting and connecting the rotary cores with their axes displaced from one another in mutually corresponding radial planes and having a handle portion; and means located between said supports for joining said tape including first and second adhesive tape control cylindrical rolls, one of the single adhesive tapes being unrolled from one supply roll around one of said rolls, and then steered into position about the other of said rolls with its adhesive side in contact with the adhesive side of the other single adhesive tape in such a way that a double adhesive tape is formed which is partially adhesive on both sides, and drawn out with a glued together overlap area through an area bounded by stops on either side, the cylindrical surface of said other roll extending beyond a tangential contact line at which said tape is drawn from said other roll so that said tape can be pulled off said cylindrical surface in a direction which can be varied between said stops.

A device for joining two adhesive tapes each having one adhesive side into a centrally overlapping double adhesive tape with the adhesive sides on either side of the overlapping area facing in opposite directions comprising: two supports for each rotatably mounting one supply roll of rolled-up single adhesive tape around a rotary core; a frame mounting and connecting the rotary cores with their axes displaced from one another in mutually corresponding radial planes and having a handle portion; and means located between said supports for joining said tape including first and second adhesive tape control cylindrical rolls, one of the single adhesive tapes being unrolled from one supply roll around one of said rolls, and then steered into position about the other of said rolls with its adhesive side in contact with the adhesive side of the other single adhesive tape in such a way that a double adhesive tape is formed which is partially adhesive on both sides, and drawn out with a glued together overlap area through an area bounded by stops on either side, the cylindrical surface of said other roll extending beyond a tangential contact line at which said tape is drawn from said other roll so that said tape can be pulled off said cylindrical surface in a direction which can be varied between said stops.
Claim 3
Dependent Claim
33 words
A device as in claim 1, wherein the axis of the second adhesive tape control roll is substantially disposed in a vertical plane containing the axis of the first adhesive tape control roll.
Claim 4
Dependent Claim
21 words
A device as in claim 2, wherein said first and second adhesive tape controls are disposed centrally between the supply rolls.
Claim 5
Dependent Claim
31 words
A device as in claim 1, wherein the first and second adhesive tape control rolls each have at least one lateral stop surface for the guiding of the single adhesive tapes.
Claim 6
Dependent Claim
21 words
A device as in claim 4, wherein each lateral stop surface is also a lateral stop surface for a supply roll.
Claim 7
Dependent Claim
22 words
A device as in claim 4 or 5, wherein a second, lateral stop surface is provided on each adhesive tape control roll.
Claim 8
Dependent Claim
25 words
A device as in claim 6, wherein the second, lateral stop surface of the first and second adhesive tape control roll lie in one plane.
Claim 9
Dependent Claim
17 words
A device as in claim 7, wherein the second lateral stop surfaces are developed to be releasable.
Claim 10
Dependent Claim
18 words
A device as in claim 8, wherein the second, lateral stop surfaces for the supply rolls have recesses.
Claim 11
Dependent Claim
25 words
A device as in claim 9, wherein at least one support is developed as an at least partially closed supply container for the supply rolls.
Claim 12
Dependent Claim
24 words
A device as in claim 10, wherein the frame includes a handle disposed opposite to the point of exit of the double edged tape.
Claim 13
Dependent Claim
15 words
