(b) a pair of rotating embossing rollers (30; 31a; 31b) provided between two of the group of conveying rollers (22, 24) and driven by a servo drive unit or servo motor (38), Embossing (32a, 32b) the workpiece (11, 11 ') into the flat transported sheet or blank (s);
(c) Thereby, the conveying roller is on its surface, the embossing roller is on its surface, and the sheet or blank embosses the work piece (11, 11 ′) into the blank or sheet. The servo drive unit having the same speed (v _s ), and the length position (y ₁₁ , y ₁₂ ) of the workpiece in the sheet or blank drives the embossing roller pair (30) ( Determined, adjusted or modified by the speed position controller (40) of 38)
(d) A method of embossing the cylindrical base shape (s ^* ) of the can wall portion (15) by molding (26).

Said sheet or blank (s) edge detector before being disposed along the path of movement of (50, 51) comprises a passage of the leading edge (s _1), embossed between the embossing roller (30) with each other The remaining time interval (T ₁ ) until the processing line or embossing position (33) is reached by the leading edge (s ₁ ) of the sheet / blank, and an indication signal (55, 55a) representing the speed The method according to claim 1, which is provided to the position control unit (40).

The method of claim 2, wherein the time interval (T ₁ ) is calculated using a distance (Y ₁ ) between a leading edge detector nose (51) and the embossing position (33).

The speed position control unit (40) adjusts the peripheral position (x ₂ ) of the embossing feature pair (32a, 32b) of the embossing roller pair (30) during the rotation to perform embossing. said workpiece Te (11, 11 '); fit is embossed _{_{_{(y 2 y 11, y 12}}} ) target position of the sheet / blank (s) (11a, 11a'), of claims 1 to 3 The method according to any one of the above.

The sheet or blank has a printed surface and a target position at which the printed workpiece (11a, 11a ′) to be mated by the embossed workpiece (11, 11 ′) is provided. 5. The method according to any one of claims 1 to 4, comprising:

The method according to claim 4, wherein the target position as an embossing region has a distance (y ₁₁ ) from the leading edge (s ₁ ).

The method according to claim 4, wherein the control system (40) as a speed position controller comprises at least one PI controller (41, 42).

The method according to any one of claims 1 to 7, wherein the servo drive (38) is an AC motor.

The method according to any one of the preceding claims, wherein the upper and lower embossing rollers (31a, 31b) are rotatably connected by a gear connection (39).
