Abstract
In the driving and guide arrangement according to the invention, the drive chain in a chain channel bounded by a guide rail and a rear wall is supported only on series of spaced, narrow support elements at least some of which may form connecting plates welded between the rear wall and the guide rail. As the narrow support elements are spaced apart from one another, fines getting into the chain channel from above readily drop between them, and emerge freely through face side and gob-side discharge openings in the chain channel. Caking of fines in the chain channel is largely prevented in the arrangements, which are fabricated as welded constructions and are therefore particularly economical to produce.
