A sealing device uses a roller drive with recesses/depressions in the peripheral surface for bowls or porringer (3), with a counter roller (5) and sealing roller (6), between which the forming foil (1) and covering foil (2) are carried. A control system is provided for controlling the position of at least one porringer (3) and its associated depression of the counter roller (5), which matches the rotational speed of the counter roller (5) to the roller drive and includes a sensor (4) for detecting the position of the porringer. The sealing device with roller drive has upstream of the counter and sealing rollers, a feed device (8) with two feed clamps (9) for gripping around the edges of the forming foil (1). |
