Abstract
A fiber cushion body comprises a first portion in which fibers have a preferential orientation along a first direction and at least a second portion having a fiber orientation and/or density different from the first portion. The fiber cushion body is processed using laser radiation to form a laser cut or laser weld.

1-20. (canceled)
A method of processing a fiber cushion body formed from thermally cross-linked fibers, the method comprising:
- applying laser radiation to the fiber cushion body to form at least a laser cut or a laser weld in the fiber cushion body, wherein the fiber cushion body to which the laser radiation is applied includes a first portion in which fibers have a preferential orientation along a first direction and a second portion having a fiber orientation and/or density different from the first portion.
The method of clam 21, wherein applying the laser radiation includes forming a fixation region in the fiber cushion body by the laser radiation, the fixation region having a density which is greater than a density of the first portion.
A fiber cushion body comprising:
- a first portion in which fibers have a preferential orientation along a first direction;
- and
- a second portion having a fiber orientation and/or density different from the first portion,
- wherein the first portion and the second portion are integrally formed, and
- wherein a laser cut and/or a laser weld is formed on at least one surface of the fiber cushion body.
An apparatus for processing a fiber cushion body formed from cross-linked fiber material, the apparatus comprising:
- a receptacle configured to receive the fiber cushion body, the fiber cushion body including a first portion in which fibers are oriented along a first direction and a second portion having a fiber orientation and/or density different from the first portion;
- and
- a laser head mounted to be movable relative to the receptacle and configured to apply laser radiation to the fiber cushion body.
