The invention relates to a method for the continuous production of an endless string of polyurethane reactive plastic material, a) at which at first the reactive components are conveyed to a mixer (1) in a metered manner, b) at which then the reactive components are mixed in the mixer (1) to a reactive mixture, c) at which subsequently the reactive mixture is discharged and d) at which a first sheet section (BM) made from a plane, flexible material which is conveyed continuously into a transporting direction (T) is coated with the reactive mixture. To produce a high qualitative string with high homogeneity the invention proposes the steps: e) Guiding of the first sheet section (BM) across a guiding element (2), which has a concave formed section (3) and a flat section (4) which follows the concave formed section (3) in transporting direction (T); f) Feeding of two lateral sheet sections (BL, BR) to the first sheet section (BM), wherein the feeding occurs into the two lateral end sections of the first sheet section (BM); g) Merging of the two lateral sheet sections (BL, BR) and the first sheet section (BM) so that a bowl-shaped structure is formed for the reception of the reactive mixture which is moved continuously in transporting direction (T). |
