(57) It comprises a sliding support (1) bearing a tool (2) for marking the flat ceramic
piece (3) with a groove (25), and a mechanism (4) for separating said piece (3) into
two parts, said mechanism forming an integral part of the sliding support (1) and
being actuated by the same lever (6) which is used to actuate said tool.
The cutting tool (2) is mounted on a shaft (30) comprising a projection (31) on the
sliding support (1) and a recess (32) in said shaft (30), said projection (31) and
said recess (32) being mutually coupled to position the shaft (30) relative to the
sliding support (1).
It also comprises a fixed stop rule (108), an element (109) which can be moved linearly
along a guide, a rotating element (110) connected to said element (109), and a fixed
sector (111), graduated in angles, relative to which moves the rotating element (110),
said element (110) comprising the guide (112) along which moves the element (109),
the latter being graduated along its length.
The cutting and separating of the piece is made easier, the correct positioning of
the cutting tool is ensured, and it is possible to make repeated, accurate cuts at
any angle.
