Procedure and device for cutting brick blanks from clay columns

摘要

The invention relates to a method and apparatus for efficiently cutting clay columns. The apparatus employs at least two supporting conveyors with one positioned downstream from the other and spaced apart a predetermined distance defining a gap therebetween. Each conveyor is wide enough to handle any desired column length so that no changes thereof are necessary when the size of the cut length changes. The conveyors or the end rollers thereof adjacent the gap are arranged to move horizontally thereby causing the gap to move. The cutting mechanism moves vertically and is operated in a coordinated fashion with movement of the gap following the point of intersection of at least one cutting wire with the conveyor plane so that clay columns are conveyed and cut simultaneously. Material adhering to the cutting wire(s) is automatically cleaned therefrom during cutting.
