of the waste is passed down into the tubular bag formed in this way and the other end of the tube over the pulled the upper edge of the container and folded or gathered for a considerable length outside the container and forms a supply from which the hose is inserted into the container when necessary and said Container rests on a tubular base, through which the hose gradually into a collecting vessel below is led down. This collecting vessel can possibly only be reached after the waste has been removed from a transport arrangement has been taken over, which carries out the transport to a collecting vessel that is next to, behind or in a certain way Distance from said tubular base is located.

The invention relates to an improvement and simplification of the Closure and the transport of the waste packages, which are led down into the tubular base. These simplifications are achieved in that the device according to the invention on the one hand with an arrangement for leading down the Waste is provided that is able to travel a certain distance regardless of thickening waste in the hose far down, and on the other hand just below, just above or built into the above-mentioned arrangement for going down, is provided with a mechanism by means of which the hose is encompassed and closed at one or more points will. The closing can be done here if necessary

at. two passages take place, which are close to, but point in one Distance from each other, or at a point with a comparatively large extent.

The closure mechanism can optionally be designed so that the hose between two such close-by closure parts is cut off or approximately in the middle of the comparatively long locking points.

The execution of the closure arrangement can within the scope of the invention done in different ways. Thus, for example, the closure arrangement can be attached to the tube part that has just been guided down Grant rotation so that the hose is twisted in one or more places and the waste carried down between them these places is included. The closure arrangement can also be designed so that an adhesive tape is wrapped around the hose so that the waste carried down is trapped between two sealing points. Closing can also with the help of heat or by electrical or chemical means by applying. Hardeners or glue. That Closing can also be done by clamping the hose together, whereupon a mechanical clamping or binding element is attached is attached to one or more locations. In the latter case, the locking arrangement can have the shape of an iris diaphragm, the on. one or more places encloses the hose and clamps it together.

109821/117 1 " ⁴ "

The closure is preferably carried out by welding the Hose, ideally directly above the arrangement for leading down, or with the help of a welding device built into this arrangement.

The arrangement for leading down the hose consists of two preferably of the same size and transversely to the direction of movement of the hose lying rollers or rollers, between which the hose is guided and which are pressed against one another and with the same. Speed in the opposite direction of rotation, rotating, being in or just below when closing the arrangement for leading down, in one or more rotational positions in the axial direction are essentially close to one another along a ridge-shaped or back-shaped part, while the material in the rollers is transported away in the rest in a significantly smaller radial extent, so that the waste trapped in the tube between the. Rolls can be transported .. With such an arrangement, the Rollers have such a diameter that the ridge-shaped or spine-shaped parts face each other when a. so long Part of the hose is passed down by the rollers that it corresponds to the distance between the lower part of the container and corresponds to its upper edge.

If, an arrangement with a cutting device for the. When tubing is used, the cut piece of tubing with the trapped waste falls into the one below Collecting vessel or on the transport arrangement.
