Abstract (en)

The buffer for rail vehicles includes a buffer plate (6) of plastic which is housed and fixed in a buffer head (1), wherein the buffer plate has a basically smooth surface on the rear side which faces the base of a recess (3) in the buffer head, while the base of the recess has projections and/or indentations (5) which may be in groove form and recessed into the base in helical fashion. An independent claim is included for a method for producing a buffer for rail vehicles in which the base of the recess in the buffer head is provided with indentations and/or projections by means of a cutting process, by laser machining, forging, eroding, embossing or casting.
