Abstract
Cylindrical foam body with a central cavity, whereby the foam body is formed by a curved flexible foam strip of which two opposite ends are fastened together, whereby the foam body has a height, whereby the strip 2 has a length, a height and a width, whereby after forming the foam body the longitudinal direction of the strip 2 is the height direction of the foam body, whereby the foam body has an outside and an inside. The foam body is provided on its outside with two or more grooves that extend over the height of the foam body and which only cut into the foam body over a part of the distance between the outside and the inside.

Cylindrical foam body (1) with a central cavity (9), whereby the foam body (1) is formed by a curved flexible foam strip (2) of which two opposite ends (3) are fastened together, whereby the foam body has a height (H), whereby the strip 2 has a length (L), a height (h) and a width (b), whereby after forming the foam body (1) the longitudinal direction (L) of the strip 2 is the height direction (H) of the foam body (1), whereby the foam body (1) has an outside (5) and an inside (8) , wherein the foam body (1) is provided on its outside (5) with two or more grooves (7) that extend over the height (H) of the foam body (1) and which only cut into the foam body (1) over a part of the distance between the outside (5) and the inside (8).
Method for making a cylindrical foam body (1), comprising the following steps in order:
- A:
- a flexible foam strip (2) is provided with cuts (5), grooves (13) or a wave pattern that do not bridge the distance between a top surface (11) and a bottom surface (12) of the strip (2),
- B:
- the strip (2) is bent around and two ends (3) of the strip (2) are connected together to fix the rounded position, whereby the axis around which the strip (2) is curved runs entirely or essentially parallel to the cuts (5), grooves (13) or wave pattern.
