ABSTRACT:
A developing procedure and a machine to carry out this procedure, based on a cylindrical tank with a horizontal shaft, which, by means of a motor with a double turning direction, moves an carrier arm that pulls a material holder with the material to be developed. The material holder passes through the bottom or base of the tank, in which the developing liquid is placed, turning alternately in each direction. The developing liquid is extracted and the tank is filled with another liquid, until a specific developing process is completed. The unit is contemplated with a microprocessor control, thus forming a simple, portable machine at a low cost.
