Abstract

An improved method and apparatus for efficiently and at an improved rate cutting an extruded clay column, strand or strip, or a portion thereof, into individual brick mouldings. A conveyor brings the uncut strip portion into a predetermined position beneath a cutting device and by causing relative vertical movement between the conveyor and a lifting table the uncut portion is transferred to the lifting table, itself comprised of a plurality of separate supports spaced apart both transversely of and in the direction of travel defined by the conveyor. While supported by the lifting table, the clay strip is cut by a plurality of cutting wires secured under tension in a frame which is lowered with respect to the table so that the wires pass through the clay. Thereafter the frame is raised to its starting position and the cut mouldings redeposited on the conveyor by again causing relative vertical movement between the conveyor and table. Then the conveyor moves the cut mouldings away from beneath the cutting device and substantially simultaneously moves a fresh uncut clay strip into cutting position so that these steps can be repeated to cut another batch of mouldings.
