Abstract

The present invention concerns a method and assembly for the capture of an outer end head (4) onto a press platen (1) in roll wrapping unit. According to the method, the outer end head (4) is taken with the help of a clamp (2) close to the press platen (1) and a rapid air flow is injected into the gap between the platen (1) and the end head (4). This air flow effects an underpressure into the gap between the end head (4) and the press platen (1), whereby the end head (4) is forced by the effect of the ambient pressure close to the press platen (1). As soon as the end head (4) is close to the platen (1), a vacuum applied via suction holes (25) in the platen (1) sucks the end head (4) against the platen (1). The assembly in accordance with the invention applies the air flow via a channel (18, 23, 24) arranged to pass through the press platen (1) into the gap between the press platen (1) and the end head (4).
