I deleted my first answer because there were some mistakes. Here's a better explanation.

An Abricht- und Dickenhobelmaschine is a jointer/planer. Another
term for a single machine that does both jobs is Abrichtdickenhobelmaschine = jointer/planer.

Abrichten is to surface, dress, true up or joint. In the US, the term surface planer is synonymous with thickness planer.


Jointer: A stationary woodworking machine that can provide a flat, true surface or edge to a board. Two long, flat surfaces called tables, arranged on either side of a rotating drum with blades (called knives in a jointer), provide support for the board on the infeed and outfeed sides. The outfeed table receives the board after it has been cut by the rotating knives, and it is set so the plane of its surface is tangent to the cylinder described by the rotating knives. Thus the outfeed table holds up the flat surface the knives have created, keeping any low spots on the board from contacting the cutting edges. Finally, a fence perpendicular to the table guides the board to joint an edge perpendicular to the face. The fence may be adjustable to give angles other than 90°.

There's also an Abrichtdickenhobelmaschine which is a combination of both machines called a jointer/planer.
