Description and

The progressive numbering head with shank for press is an automatic pneumatic numerator and is used for marking variable data in a progressive incremental way such as serial codes.

The wheels groups is flat for vertical marking with a press and the numbering head has a structure with a tang for attachment to the press.
The shank is made according to the characteristics of the customer’s press.


The numerator is designed to withstand high marking pressures.


It is composed of wheels with ten faces that contain the numbers, but it is possible to make wheels with letters or symbols.


It is possible to make wheels with the sequence of digits 0-9, but it is also possible to make wheels with multiple repetitions of only a few digits (for example if you want to make a wheel with only 1 and 2, the sequence could be 1-1- 1-1-1-2-2-2-2-2-2)


The thickness of the wheels determines the center distance of the numbers in the marking.


In the mod. PS9 the wheels with numbers and letters are of standard thickness 9.1 mm while those with symbols (Kg, L for example) can be thicker.

GOMG also produces the PS8 progressive numerator model with 8 mm thick wheels and PS6 with 6 mm thick wheels.


On the wheels there can be characters from 1 to 12mm in height, while for symbols it depends on their complexity.


The numbering head has the automatic increment function, therefore every time a new marking cycle is started the starting value must be set manually by simply rotating the wheels until the desired value is dialed.


The number of wheels varies depending on the number of digits that make up the values ​​required by the customer’s application.


Each wheel is coded so it is easy to identify the assembly position


The numerator is easy to assemble and requires little maintenance. However, GOMG still offers the maintenance and regeneration service of its numerators.


The numerator is supplied including fittings for connecting the pneumatic tubes.


The body of the numerator is made with a coupling seat with two threaded holes for installation on GOMG marking wheels or on supports with press tang.


Further solutions for coupling to other marking machines are possible.
