Frame profile of an outer frame and/or leaf frame, and method for the production thereof

A frame profile of an outer frame and/or a leaf frame of a window or a door, the frame profile comprising a core profile of a plastics material, wherein a casing shell is disposed on at least one external wall of the core profile, wherein the at least one external wall has at least one fastening groove that extends in a longitudinal direction across an entire length of the core profile, via which fastening groove the at least one external wall in a region of the fastening groove is repositioned inward into the core profile, and a groove base of the fastening groove has a height which is at least 50% of a total height of the at least one external wall of the core profile, wherein the casing shell is fastened in the fastening groove and covers the fastening groove, and the casing shell on an internal face thereof that points toward the core profile has a pair of fastening elements which are spaced apart in a height direction and protrude toward the core profile and via which the casing shell is not adhesively fastened in the fastening groove, wherein a fastening element as a reference web is configured with a run-up ramp or a run-up curve pointing toward the groove base, the reference web having a greatest thickness of all the fastening elements and being configured to be brought to bear on the at least one external wall with the fastening groove and serving as a detent in a corner of the fastening groove and as a spacer in relation to a vertically running groove base, wherein disposed between the pair of fastening elements, via which a non-adhesive fastening is achieved, is at least one further pair of adhesive feet which are spaced apart in the height direction and via which an additional adhesive connection is implemented, via which additional adhesive connection the core profile is combined with the casing shell by an adhesive bonding so as to be resistant to shear.
