Abstract

A method of manufacturing a razor head component that includes the steps of: providing a strip of material elongated along a first direction, the strip having first and second edges parallel with the first direction; having a first portion that includes a first edge, a second portion having a second edge, and an intermediate portion intermediate the first and second portions; bending the intermediate portion of a part of the strip about a bending axis parallel to the first direction; and fixing a razor blade onto the second portion of the part.

First claim

The invention claimed is:

1. A method of manufacturing a razor head component comprising:
a) providing a strip of blade support material elongated along a first direction, the strip having first and second edges parallel with the first direction, a first portion including the first edge, a second portion including the second edge, and an intermediate portion intermediate the first and second portions,
b) bending the intermediate portion of a part of the strip about a bending axis parallel to the first direction,
c) fixing a razor blade onto the second portion of the part, step c) being performed after step b), and
d) forming a groove in the strip at the intermediate portion, the groove extending along the first direction, step d) being performed prior to step b).

2. The method according to claim 1 , further comprising, prior to step b), the following step:
forming a notch in the strip in two locations separate from each other along the first direction, wherein the part is defined between the two locations.

3. The method according to claim 2 , wherein the locations extend from the second edge toward the first edge, both in the second portion and the intermediate portion.

4. The method according to claim 1 , further comprising the following step: e) separating an individual blade support from the strip.

5. The method according to claim 4 , further comprising, prior to step b), the following step:
forming a notch in the strip in two locations separate from each other along the first direction,
wherein the part is defined between the two locations,
wherein a separation portion extends from the notch to the first edge, and wherein step e) comprises breaking the separation portion.

6. The method according to claim 4 , wherein step e) is performed before step c), the part corresponding to the individual support.

7. The method according to claim 1 , wherein step c) comprises:
providing a razor blade comprising a handling portion and a head portion, the head portion comprising a fixation portion and a cutting edge,
placing the fixation portion in correspondence with the second portion of the part,
adhering the fixation portion to the second portion.

8. The method according to claim 7 , further comprising, after step c), the following step:
removing the handling portion.

9. The method according to claim 1 , comprising moving the strip along a process path, and repeating at least steps b) and c) for different parts of the strip.

10. The method according to claim 9 , further comprising the following step :
separating an individual blade support from the strip,
wherein the process path extends along the first direction at least from step b) to step c).

11. The method according to claim 9 , wherein moving the strip comprises:
g1) having a guiding device to mechanically cooperate with a complementary guided portion of the strip,
g2) moving the guiding device along the process path, thereby moving the strip,
g3) removing the cooperation of the guiding device and of the guided portion,
g4) moving the guiding device in a direction opposite to the process path, without moving the strip.

12. The method according to claim 11 , further comprising, prior to step b), the following step:
forming a notch in the strip in two locations separate from each other along the first direction, wherein the part is defined between the two locations,
wherein the guided portion comprises a notch extending at least partly through the thickness of the strip, and wherein the notch is performed at step d).
