Abstract: A base for manual ceramic cutters, which is provided with a support surface for the ceramic parts to be cut, the base including a rigid profile in the central longitudinal area, which rigid profile is secured to the supports of longitudinal displacement guides for a tool-holder head; and two lateral platforms mounted on the rigid profile by longitudinal shafts, which lateral platforms can be lowered between a horizontal use position, in which they form a support surface for the ceramic parts to be cut, and an inoperative position, in which the base defines a smaller surface area.

Abstract: The invention relates to a cutting and separating device applicable to manual ceramic cutters, comprising: a carriage; a collapsible handle with a cutting tool; a toothed part comprising a separator for separating ceramic parts; springs for holding the toothed part in an inoperative position as well as a toothed actuator in an engaged position with the toothed part; and a manual trigger element for disengaging the toothed actuator. The rotation of the handle past a pre-determined angle causes the engagement of the toothed actuator in the toothed part; the descending rotation causes the toothed actuator to rotate the toothed part until an operative position of the separator is reached; and the actuation of the trigger element causes the release of the toothed part and the return thereof to the inoperative position.

Abstract: The protective cooling cover comprises a hollow shell defining a generally semi-cylindrical cavity (15) that covers a portion of a cutting disc (2) at the top thereof and that is delimited by two lateral walls (11, 12) and a curved perimeter wall (13), a cooling device including a tube connected to a cooling liquid supply and to a cooling liquid projecting nozzle (31), and a fastening device for fixing the cooling liquid projecting nozzle (31) at different positions within the cavity (15) of the shell for projecting cooling liquid to different areas of the cutting disc, the fastening device including a plurality of first fasteners (17) connected to the periphery of the cavity, and a second fastener (32) connected to the cooling liquid projecting nozzle (31), the first and second fasteners (17, 32) providing a snap fit releasable connection.
