Forming tool, in particular a kneading tool

Abstract

The invention relates to a forming tool, in particular a kneading tool, which has a base body ( 12′ ), in which at least one forming element ( 21 ) is disposed, inclined at a first angle of inclination (α 1 ) to a central axis (M) of the deformation tool ( 12 ), which results in the determination of an inlet chamfer (S) of the forming element ( 12 ). According to the invention, it is provided that in the surface ( 21′ ) of the forming element ( 21 ) running in an inclined manner below the first angle of inclination (α 1 ) a recessed surface structure ( 22 ) is formed, which has at least one recess ( 23 ) with a trailing edge ( 23 a ), and that the trailing edge ( 23 a ) of said recess ( 23 ), related to the inlet chamfer (S) of the forming element ( 21 ) defined by the first angle of inclination (α 1 ), has a second angle of inclination (α 2 ), which is oriented towards the opposite direction with regard to the first angle of inclination (α 1 ), and the absolute value thereof is larger than or equal to the absolute value of the first angle of inclination (α 1 ).
