Abstract

There is disclosed a method for packing articles, liquid or loose material in film bags which are conveyed through a filling station in a continuous web of bag items, wherein the bag openings are kept open for reception of articles, after which the bags are closed and separated from the web. In order to increase the filling rate and make the bags cheaper, the bag web is provided with a central support region extending longitudinally of the bag web and connecting bag items that are disposed side by side transversely of the web. The central support region is conveyed on a support rail along the conveyor path through the filling station and formed as an entirely or partially closed channel. The peripheral areas of the bag items at the outermost opposite bag opening edges of two juxtaposed bag items are brought into guiding connection with guide means adapted for retaining and guiding edge areas at opposing bag opening edges along a conveyor path through the filling station. In connection with this passage, the guide means will force the bag opening edges apart for successive opening of the bags in the filling station, and then, after filling the bags, joining the bag opening edges for closing the bags again.

Description

technical field [0001] The invention relates to a method for packaging articles, liquids or loose materials in film bags which are conveyed in a continuous web of bag items through a filling station, wherein the bag opening is left open for receiving articles , thereafter the bag is closed and separated from the net, by which method the bag net is initially and along its open edge guidedly connected to a guide member adapted for Peripheral regions at opposing bag opening edges are held and guided along a conveyor path through the filling station, and when passed in conjunction therewith, the guide members force the bag opening edges apart for use in the filling station. The bag is opened continuously in the filling station and subsequently, after filling the bag, the bag opening edges are joined for closing the bag, by which method the opposite bag opening edges are spread apart from each other , and by said method, by conveying said bag web on a support track to engage said ...
