Abstract

The machine for grinding sheet-like elements, particularly tiles and slabs made of ceramic material, natural stone, glass or the like, includes a base framework, means for advancing at least one sheet-like element on a movement plane (A) along an advancement direction (B), the sheet-like element being provided with a pair of opposite first sides to be ground and a front side transversal to the first sides and defining the advancement front of the sheet-like element, means for machining the first sides adapted to intercept the sheet-like element in the motion thereof along the advancement direction (B), means for square-positioning the sheet-like element on the movement plane (A) comprising at least one abutment element which defines at least two support points adapted to contact the front side for arranging it in a position orthogonal to the advancement direction (B).

Claims8

Dependent claims

A machine for grinding sheet-like elements comprising:

at least one base framework;
flexible elements for advancing at least one sheet-like element mounted on said base framework and adapted to the movement of said at least one sheet-like element on at least one movement plane (A) along at least one advancement direction (B), said sheet-like element being provided with a pair of first opposite sides to be ground and at least one front side transversal to said first sides and defining the advancement front of the at least one sheet-like element;
wheels for machining said first sides which are arranged in proximity of said movement plane (A) and they are adapted to intercept said sheet-like element in its motion along said advancement direction (B);
at least one abutment element for square-positioning said sheet-like element on said movement plane (A);
wherein said at least one abutment element defines at least two support points different from each other and adapted to contact said front side for arranging it in a position substantially orthogonal to said advancement direction (B), and
wherein said at least one abutment element is moveable along said advancement direction (B).
