Notes: designed to code alphanumeric symbols by means of punches.
The coder 341 is planned to code alphanumeric symbols by means of punches on the upper side of the product to be coded. Moreover, this coder has the possibility to be connected with a test bench. The coding is realized by the clash between the types-holder and the product only when the test is successful. Then, immediately after having coded, the types-holder goes back in the stand-by position and the tested product can be taken away.
