Abstract
Disclosed herein is a film fitting head which holds a tubular film fitted on a mandrel in a stable position and can prevent the film from rotating and being displaced in a peripheral direction. The film fitting head (40) includes a mandrel (M) for receiving a tubular film (L) in a fitted state in a film supply position, feeding the tubular film in a film fitting position, and fitting the tubular film onto a body portion of a container. The mandrel (M) includes a film holding portion (85) provided above a lifting member (88) located in a standby position. An outer peripheral surface of the film holding portion (85) has a tapered surface that is tapered down toward a top, and an outer peripheral length of a lower end (85a) of the film holding portion (85) is set to be approximately equal to a peripheral length of the tubular film (L) in an open state.
