Abstract

A dispenser dispenses a material that is adhesive on at least one side, wherein at least one adhesive side of the material is covered with a liner, which has at least one slit running in a longitudinal direction, with the material placed on the liner being wound into a roll in the form of an Archimedean spiral and at least one slit being located beneath the material covered with the liner. The dispenser comprises a (i) frame, one end of which has a receptacle for the material, so that the material roll is rotatably mounted, (ii) a first guiding device, by means of which the material is guided together with the liner to a first dispensing edge, at which at least a first liner strip is pulled off, with the liner being separated at the slit located under the material, while the material with the remaining second liner strip is guided to a second dispensing edge, and (iii) a second guiding device, by means of which the material, together with the remaining liner strips, is guided to a second dispensing edge, at which the remaining second liner strip can be pulled off.

First claim

The invention claimed is:

1. A dispenser adapted for dispensing a material that is adhesive on at least one side, wherein at least one adhesive side of the material is covered with a liner, the liner having at least one slit running in a longitudinal direction to provide a first liner strip and at least one second liner strip, with the material placed on the liner being wound into a material roll in the form of an Archimedean spiral and the at least one slit being located beneath the material covered with the liner, the dispenser comprising:
a frame, wherein one end of the frame has a receptacle for the material, so that the material roll is rotatably mounted;
a first guiding device, by means of which the material is guided together with the liner to a first dispensing edge, at which at least the first liner strip is pulled off, with the liner being separated at the slit located under the material, while the material with the at least one second liner strip remaining thereon is guided to a second dispensing edge;
an electrically or pneumatically driven roller configured to pull the first liner strip off the material over the first dispensing edge and then to wind the pulled-off first liner strip onto the electrically or pneumatically driven roller, and
a second guiding device comprising a removal plate that is a flat sheet or strip of plate material having a top surface, an opposite bottom surface and a total length defined between a first end and a second end, wherein the second end of the flat sheet or strip is adjacent to the first guiding device such that the second end of the flat sheet or strip is provided between the first guiding device and the first end of the flat sheet or strip, wherein the second guiding device is configured such that the material, together with the at least one second liner strip remaining thereon, is guided to the second dispensing edge, provided at the first end of the flat sheet or strip of the removal, at which the at least one second liner strip remaining thereon is removable therefrom the material.

2. The dispenser according to claim 1 , wherein the material is a series of at least single-sided adhesive blanks arranged successively.

3. The dispenser according to claim 1 , wherein the liner has only one slit.

4. The dispenser according to claim 3 , wherein the width ratio of the two liner strips being produced is between 20:80 and 30:70.

5. The dispenser according to claim 4 , wherein the width ratio of the two liner strips being produced is exactly 20:80.

6. The dispenser according to claim 3 , wherein a total width of the first liner strip is narrower than a total width of the second liner strip and a width ratio of the first liner strip to the second liner strip is between 10:90 and 30:70.

7. The dispenser according to claim 1 , wherein an uptake of the material roll is braked.

8. The dispenser according to claim 1 , wherein the at least one second liner strip is first pulled over the first or second dispensing edge, using an electrically or pneumatically driven roller.

9. The dispenser according to claim 1 , wherein the material is transferred further by pulling on both the first liner strip and the at least one second liner strip on a drive side.

10. The dispenser according to claim 1 , wherein the material has a width of 10 to 300 mm and a length of 10 to 320 mm, with the liner having a slit measuring 2 to 40 mm.

11. The dispenser according to claim 1 , wherein the material has a liner peeling strength of 2 to 50 cN/cm and a bending stiffness of less than 0.5 mNm.

12. A method for dispensing the material according to claim 1 , the method comprising:
dispensing material from the dispenser according to claim 1 to provide dispensed material;
manufacturing an industrial component comprising the dispensed material.

13. The method according to claim 12 , wherein the industrial component is an automotive component or a cable fastening component.
