Abstract
This invention relates to a printing machine provided with a printing head comprising a plurality of coaxial rotating printing wheels, wherein the control wheel is fast in translation with a carriage mobile parallel to the axis of said printing wheels and bearing two stepper motors, of which the first allows said carriage to slide and the second drives said control wheel in rotation. The invention is particularly applicable to the printing of parts, cables, wires, etc. . . . when they are manufactured.
Claims4
In a printing machine, a printing head comprising a plurality of parallel coaxial printing wheels rotatable about a first axis, each wheel being provided with printing characters,
- a carriage movable along a line parallel to said first axis,
- a first stepper motor and a second stepper motor carried by and movable with said carriage, actuation of said first motor causing said carriage to move along said line,
- a control wheel carried by and movable together with said carriage, said control wheel being driven by said second stepper motor for rotation about a second axis parallel to said first axis, said control wheel being adapted to engage directly any selected one of said printing wheels on actuation of said first motor and to bring a desired printing character on said selected wheel into printing position on actuation of said second motor;
- said first and said second stepper motors being independently operable.
