Abstract: A device to prevent the drying of nozzles of a machine for the preparation of fluid coloring products having a delivery head includes an anti-drying member and an actuation mechanism to take the anti-drying member from an inactive position distant from the delivery head to an operating position in contact with the delivery head. The actuation mechanism includes an actuation lever oscillating with respect to a fixed support and a group of parallelogram levers commanded by the actuation lever and connected to the anti-drying member so as to keep an upper surface of the anti-drying member constantly parallel to the lower surface of the delivery head during the movement from the inactive position to the operating position.

Abstract: Distribution device for coloring products, comprising a collector for dispensing nozzles and corresponding nozzles mounted thereon. The collector comprises a containing body provided with one or more through cavities. In correspondence with one end associated to an external surface the containing body is provided with a positioning element. The containing body is provided with a seating, inside the external surface, disposed at the end of each of the through cavities, defining a wider portion with respect to the cross section of the corresponding through cavity.
