Sealing station

摘要

A sealing station (1) has a vent system with an inlet channel and an outlet channel in an area of each of the cavities (14) in a lower mold (5). The cavities accept the pocket-like depressions (12) of the bottom sheet (11). During a sealing operation, a vent space defined between each depression and each cavity circulates air introduced through the inlet channel. The air escapes through the outlet channel.
