Problems solved by technology

[0005] However, this engagement is not strong enough and axial slippage can occur between the upper edge of the pocket web and the associated conveyor belt transport, which can create uncertainty as it is not known whether the item being conveyed is fully synchronized with the conveyor belt
In addition, the height position of the side regions of the web pressed between the conveyor belts may deviate, which may be important for some specific purposes, since it is not clear whether the pocket being filled is in the position required for example relative to the pattern on the pocket fully sealed

Embodiment Construction

[0015] From a storage not shown, the web of bags 1 of synthetic material is conveyed in the direction of the arrow on a smooth track 2 (cross-section 2a) having a circular portion 3 facing the direction of bag conveyance. The web of pockets is suspended from the upper part of a plastic film designed for this purpose, which is provided with the usual cut-outs and weakened spots (they are not shown). Furthermore, the upper part is provided with several perforations for representing holes at a fixed distance from each other. The track is changed to a thicker core rod 4 (cross-section 2b) with grooves 5, 6 designed on both sides. The width and depth of the grooves correspond to the minor axes 7 , which are arranged at fixed distances on the two endless chains 9 , 10 by means of fittings 8 . The short shaft moves synchronously with the pocket web 1 so that the short shaft penetrates the thin layers 11, 12 on the left and right sides of the upper portion of the pocket web from both...

Abstract

Methods are known for conveying bags in the form of a continuous web such that they open at a suitable place during continuous conveyance and during maintenance of the open condition so they can be filled and sealed after closing. Prior art methods utilise complicated methods for retention. According to the invention, the bag web is suspended on horizontal studs mounted on carrier chains running in such a way that the bags open and a surrounding groove around the studs along the chains prevents the bags from falling off during passage of filling stations etc.

Description

technical field [0001] The present invention relates to a method and apparatus for packaging articles in film pockets which are conveyed in a continuous web through a filling station where the individual pocket articles are filled and the pockets are then sealed and removed from the continuous web Branch out to create a single package. Background technique [0002] A basic example of this technique is mentioned in EP-696997, where it is mentioned that the opposite upper edge regions of the web of pocket items are made with curved flange portions formed by grooves for pulling in on the transfer rod , the transfer rods have mutually expanding parts in the direction of transfer for creating openings for pocket items so that these pockets can be filled, for example, by means of a funnel located above, after which the transfer rods are narrowed against each other in order to temporarily close the filling pocket items. The pocket items are then completely sealed by being welded ...
