摘要:
Device and method to produce panels of mosaic tesserae (13), wherein at least a supporting and/or lining sheet (12) is applied on a visible face of the tesserae (13) arranged inside an advancing frame (14); the device comprises feed means (16) and means to apply the sheet (12) cooperating with the feed means of the frame (14), and the application means comprise cutting means (20) able to cut to size a segment (12a) of the sheet (12) and suction drum means (18) able to retain at least temporarily, on their outer cylindrical surface, the segment (12a) of sheet (12) and to release it onto the tesserae (13).
摘要:
Apparatus to amalgamate a paste of vitreous material in the molten state with an additive material in the form of granules, scales, slivers or filaments, made of metal, of other types of glass or other material in order to obtain a vitreous compound. The apparatus comprises containing means (11) to contain the paste of vitreous material, mixing means (15) to convey the vitreous compound downwards, in its molten state, towards rolling means (12) to produce manufactured articles. The mixing means (15) comprise at least a first pair of mixing cylinders (19a, 19b) having the respective axes of rotation (20a, 20b) arranged substantially horizontal, parallel to each other and substantially parallel, or slightly inclined, with respect to the direction in which a rolling force is applied by said rolling means (12).
