Document Type and Number:
Japanese Patent JP4364090
Kind Code:
B2
Abstract:
A device for manufacturing, filling and sealing thermoplastic sacks comprises a station, which comprises a forward draw unit for intermittently pulling forward a web of thermoplastic blown film and for its suspended feed in a vertical direction through a cross welding and cross severing mechanism, which provides the leading end of the blown film web with a cross weld and severs from said web a tubular segment above a gripping and transport mechanism. In order to pass the leading end of the blown film web quickly and without limply withdrawing to one side through the cross weld and cross severing mechanism into a stretched hanging position, there is a wall parallel to the feed path of the blown film web, and above the wall there are in its top region blowing air nozzles, facing the feed direction, between the wall and the feed path.
