ABSTRACT:
Apparatus for cutting substantially flat ceramics pieces, having a frame for supporting the piece to be cut, over which a head carrying a cutting line-scoring tool slides. A freely-oscillating fork is arranged rearward of the position of engagement of the scoring tool, with legs on the fork resting on the piece to be cut on both sides of the scoring or marking line. A cranked lever is articulated on the frame and has a forward end projecting through an opening in the frame and a forward arm actuated by the tool carrier head at the instant the piece is broken or severed, to cause the rearward end to protrude and support the piece for breaking or severing.
