The machine comprises a print table (8) and a print head (3) which are intended for the printing of characters on labels (11) borne by a continuous strip (10). The print head (3) comprises a pusher (32), a lateral stop (29) and two detention notches (30, 31), and the print table (8) has a rotary cam (33) with return prism (34) and cocking spring (35), having three lifts (38). Upon the typing, one lift is turned by the pusher (32) and the following lift comes laterally against the stop (29). When the print head rebounds, this lift engages in a notch (30) and holds the print head spaced from the print table. This arrangement is provided to prevent a second printing of characters on the labels as a result of rebound. In a variant, the rotary cam is replaced by a reciprocating bolt. |
