MACHINES FOR DECORATION, IN PARTICULAR FOR DECORATION OF CERAMICS, AND METHOD OF PERFORMING BELT FOR DECORATION OF THE NOTED CERAMICS Russian patent published in 2017 - IPC B28B11/00 B28B11/04 B29D29/00 F16G3/10 G03G15/00 

FIELD: mechanics.

SUBSTANCE: machine contains a belt in the form of a closed loop for transferring the decor to the receiving surface of the ceramic product and conveyor rollers around which the belt is wound and moves while rotating. Moreover, at least one of the noted conveyor rollers comprises a central portion and two end portions opposite to each other. At least one of the noted end portions freely rotates with respect to the other of the noted portions. The belt comprises a central portion with a small thickness and defining respective side edges attached to the flat, co-operating belts stretched to the noted end portions. The distance (A) between the two axial lines of the noted flat belts is shorter than the distance (B) between the locations with the maximum diameters (D) at the noted opposite end portions. The manufacturing method of the belt includes stretching due to the elasticity of the flat belts so that the size of their circumferential length substantially corresponds to the circumferential length of the tubular film. The edges of the tubular film are joined to the edges of the flat belts during the noted stretching of the flat belts. The stretching of these flat belts is eliminated.

EFFECT: increased efficiency of the decor transfer to the receiving surface and simplified manufacture of the belt.
