A transfer decorating machine that utilises powdered material or granules comprises: a mobile rest surface (10), on which the objects to be decorated are translated according to a predetermined direction; a device for the application of a decoration, operating above the mobile rest surface (10) and provided with a mobile transfer belt (3), which is a closed loop between movement rollers (2, 20) having mutually parallel axes, and serves the function of receiving a decoration realised with powdered material or granules (9) and then transferring it on objects to be decorated. Said device comprises a first unit (100) suitable for composing a decoration on the transfer belt (3) and a second unit (200) that carries out the transfer of the decoration from the transfer belt (3) onto an object to be decorated. The transfer belt (3) is commanded to move in a direction concordant with that of the mobile rest surface (10). The second unit (200) comprises a section located in the lower part of the transfer belt (3) that has the external side thereof facing downwards and facing, at a predetermined distance, a surface to be decorated (11) of an object lying on the mobile rest surface (10). This section extends between a curved surface of an abutment (17, 2) and a movement roller (20). There are means operating correspondingly on the internal side of the said section of the transfer belt (3) to direct jets of air towards it, said jets of air generating a situation of turbulence. |

1. A transfer decorating machine (1) that utilises powdered material or granules (9) comprising:
a rest surface (10) that is mobile in a predetermined direction; a device for the application of a decoration, operating above the said rest surface (10) and provided with a mobile transfer belt (3), which is a closed loop between movement rollers (2, 20), and serves the function of receiving a decoration realised with powdered material or granules (9) and transferring it towards said rest surface (10), said device comprising a first unit (100) suitable for composing one said decoration on the transfer belt (3) and a second unit (200) suitable for carrying out the transfer of the said decoration from said transfer belt (3), said mobile transfer belt (3) being commanded to move in an advancement direction (Y), characterised in that said second unit (200) comprises a lower section (K) of the said transfer belt (3) that has the external side thereof facing downwards and facing said mobile rest surface (10); said section (K) extending between a first abutment (2, 17, 30) arranged upstream and a second abutment (S, 19, 20, 30) arranged downstream; there being provided actuator means (12, 13, 14, 18, 22, 23) operating on the internal side of the said section (K) and suitable for rapidly moving the gas present in the proximity of the said section (K) and for transmitting a vibration to the said section (K) by means of the said gas. |
