Mounting plate for furniture hinges and method for manufacturing it

A mounting plate for an adjustable mounting of a supporting arm of a hinge on a wall of a furniture piece, said mounting plate includes an upper portion facing a supporting arm wherein at least said upper portion is made with an inverted U-shaped profile by punching and pressing from sheet metal, and has in a carcase-interior end area a tap for a mounting screw locking the supporting arm of the hinge, and on its end pointing out of the carcase-interior an open-ended longitudinal slot, said mounting plate includes a reduced-diameter neck section of a threaded spindle provided at a mounting-plate side bottom end of a threaded section screwed into a threaded bore in the supporting arm, on whose end facing away from the threaded section a holding head of increased diameter is set, said neck section extending from a bottom end of the threaded section of the threaded spindle to a top end of the holding head and the length of the neck section being greater than the thickness of the sheet metal starting material used for the making of the mounting plate, said reduced diameter neck section being adapted for insertion into said open-ended longitudinal slot, comprising said mounting plate including a web (52) whose forward end is deformed over the length of the longitudinal slot to a plane running parallel to the rest of the web, and said web having margins wherein along the margins of the web (52) of the mounting plate (42) which define the longitudinal slot (39), ridges (100) are formed out of the plane of the web (52), so that a distance measured from one flat side of the undeformed web (52) to the opposite boundary surface of the outwardly formed ridges (100) is greater than the material thickness of the web (52) in the undeformed area.
