Abstract
A planing machine for the mining of minerals particularly a coal plane which has a planing chain guided on the filling side, and comprises two individual planes with plane bodies interconnected by an articulated connection, a sword plate of each plane body grips under a conveyor chute. The plane bodies are each supported on each plane against a conveyor chute sidewall on the coal face side by means of a horizontal, centrally mounted roller. Vertical bearing pins of the rollers form floating shafts for the plane bodies. Sword plates are individually connected to the planing chain and are not interconnected by otherwise used hinges. This makes for a good ability to negotiate curves and adaptability when traversing curves as well as troughs and saddles.
