Abstract

A manual device for applying a coating to a support by means of tape, in which a first angle formed between the median plane of the applicator tip and the half-line extending from the middle of the application edge of the applicator tip and passing through the point arranged at the intersection of the outer periphery of the first winding and the radius of the first winding perpendicular to the median plane, is between −1° and 10°, whereas a second angle formed between the median plane and the half-line extending from the middle of the application edge and passing through the point arranged at the intersection of the outer periphery of the second winding and the radius of the second winding perpendicular to the median plane, is between 1° and 10°.

First claim

The invention claimed is:

1. A manual device for applying a coating to a support by tape comprising a supply reel mounted on a first bearing and comprising a first tape winding, a take-up reel mounted on a second bearing and comprising a second tape winding, and an applicator tip to apply the coating carried by the tape onto a support, the applicator tip extending in a longitudinal direction and having an application edge, the application edge and the longitudinal direction defining an application plane while a plane perpendicular to the application plane and extending in the longitudinal direction and passing through a middle of the application edge forms a median plane of the applicator tip, in which an angle between axes of each of the first and second bearings and the application plane is greater than or equal to 30 degrees, wherein the first bearing and the second bearing are arranged on either side of the median plane of the applicator tip and, are considered projecting into the application plane, a first angle formed between the median plane and a half-line extending from the middle of the application edge and passing through a point arranged at an intersection of the outer periphery of the first winding and a radius of the first winding perpendicular to the median plane, is between −1 and 10 degrees whereas a second angle formed between the median plane and a half-line extending from the middle of the application edge and passing through a point arranged at the intersection of the outer periphery of the second winding and a radius of the second winding perpendicular to the median plane, is between 1 and 10 degrees, wherein the tape cooperates only with the supply reel, the take-up reel and the applicator tip.

2. A manual device for applying a coating to a support by tape according to claim 1 , wherein the applicator tip comprises a guide portion having a first twisted surface and a second twisted surface, the first twisted surface cooperating with the tape downstream of the supply reel and upstream of the application edge while the second twisted surface cooperates with the tape downstream of the application edge and upstream of the take-up reel, the tape being configured to travel from upstream to downstream within the manual device.

3. A manual device for applying a coating to a support by tape according to claim 1 , wherein the first bearing and the second bearing are offset in relation to one another in the longitudinal direction.

4. A manual device for applying a coating to a support by tape according to claim 3 , wherein, considered in the longitudinal direction, the second bearing is arranged between the applicator tip and the first bearing.

5. A manual device for applying a coating to a support by tape according to claim 1 , wherein the first winding and the second winding are offset in relation to one another in a direction perpendicular to the application plane.

6. A manual device for applying a coating to a support by tape according to claim 2 , wherein the first winding is offset in relation to the second winding on the side of the first twisted surface whereas the second winding is offset in relation to the first winding on the side of the second twisted surface.

7. A manual device for applying a coating to a support by tape comprising a supply reel mounted on a first bearing and comprising a first tape winding, a take-up reel mounted on a second bearing and comprising a second tape winding, and an applicator tip to apply the coating carried by the tape onto a support, the applicator tip extending in a longitudinal direction and having an application edge, the application edge and the longitudinal direction defining an application plane while a plane perpendicular to the application plane and extending in the longitudinal direction and passing through a middle of the application edge forms a median plane of the applicator tip, wherein the first bearing and the second bearing are arranged on either side of the median plane of the applicator tip and, are considered projecting into the application plane, a first angle formed between the median plane and a half-line extending from the middle of the application edge and passing through a point arranged at an intersection of the outer periphery of the first winding and a radius of the first winding perpendicular to the median plane, is between −1 and 10 degrees whereas a second angle formed between the median plane and a half-line extending from the middle of the application edge and passing through a point arranged at the intersection of the outer periphery of the second winding and a radius of the second winding perpendicular to the median plane, is between 1 and 10 degrees, wherein the tape cooperates only with the supply reel, the take-up reel and the applicator tip.

8. A manual device according to claim 7 , wherein the applicator tip comprises a guide portion having a first twisted surface and a second twisted surface, the first twisted surface cooperating with the tape downstream of the supply reel and upstream of the application edge while the second twisted surface cooperates with the tape downstream of the application edge and upstream of the take-up reel, the tape being configured to travel from upstream to downstream within the manual device.

9. A manual device according to claim 7 , wherein the first bearing and the second bearing are offset in relation to one another in the longitudinal direction.

10. A manual device according to claim 9 , wherein, considered in the longitudinal direction, the second bearing is arranged between the applicator tip and the first bearing.

11. A manual device according to claim 7 , wherein the first winding and the second winding are offset in relation to one another in a direction perpendicular to the application plane.

12. A manual device according to claim 8 , wherein the first winding is offset in relation to the second winding on the side of the first twisted surface whereas the second winding is offset in relation to the first winding on the side of the second twisted surface.

13. A device, comprising:
a first reel coupled to a first bearing and comprising a first tape winding;
a second reel coupled to a second bearing and comprising a second tape winding; and
an applicator tip configured to apply a coating carried by a tape onto a support, the applicator tip extends in a first direction and has an edge that each defines an application plane;
the applicator tip further includes a median plane that is perpendicular to the application plane, extends in the first direction, and passes through a middle portion of the edge;
wherein the first bearing and the second bearing are arranged on either side of the median plane and project into the application plane;
wherein a first angle formed between the median plane and a line that extends from the middle portion of the edge, and that passes through a point arranged at an intersection of a periphery of the first tape winding and a radius of the first tape winding perpendicular to the median plane, is between −1 and 10 degrees; and
wherein a second angle formed between the median plane and a line that extends from the middle portion of the edge, and that passes through a point arranged at an intersection of a periphery of the second tape winding and a radius of the second tape winding perpendicular to the median plane, is between 1 and 10 degrees, wherein the tape cooperates only with the first reel, the second reel and the applicator tip.
