A method of producing non-woven elements made from a raw material comprising grass plants. A first intermediate product is made of per-prepared, damp natural fibers having a dry substance concentration of between 30%-50%, more preferably approximately 40%. The invention also relates to the production of a second intermediate product from the first intermediate product according to the following steps. The natural fibers are predried, thermoactive binding fibers are added thereto, additives are sprayed thereon and the order of the step can vary and/or individual steps may be carried out simultaneously with one another. Preferably, the raw material is silated grass and, in order to produce the first intermediate product, the raw material is defibered and the digestible components of the raw material are separated therefrom.

A method of manufacturing an insulation mat from a raw material comprising grass plants, whereby a first intermediate product (101) comprises preprocessed, moist natural fibers having a dry substance content of 30% to 50%, preferably approximately 40%, and a second intermediate product (102) being manufactured from the first intermediate product (101) by the steps of:
The method according to claim 32, further comprising the step of concentrating the digestible parts into one of a special feeding stuff or to a nutrient additive (105), wherein the digestible parts (104) contain mainly acids, proteins and minerals.
The method according to claim 36, further comprising the step of forming the second intermediate product (102) so as to comprise a dry substance content of approximately 60% to 85% for manufacture of the fleece, and providing residual drying when heating the fleece in order to activate (12) the binding fibers.
The method according to claim 36, further comprising the step of forming the second intermediate product (102) to comprise a dry substance content of approximately 40% to 60%, positioning the second intermediate product (102) on a conveyor belt, post-drying the second intermediate product (102), loosened up the second intermediate product (102), followed by the activation (12) of the binding fibers.
A fixture for the manufacturing of an insulation mat from grass plants, comprising a core unit (22) for producing a second intermediate product (102) from a first intermediate product (101), whereby the core unit (22) comprises:
