Machine for filling bags with loose products, in particular to a forming and filling machine, in which the bags fed one at a time to the single pick-up position are formed along the line from a tubular material, preferably by means of a forming station provided with means for sealing the bottom of each bag, arranged in said pick-up position.

An ice bagger is provided. The ice bagger includes an ice hopper into which ice is disposed from an ice manufacturer. The ice hopper further includes an ice agitator. The ice hopper defines an ice trough positioned beneath the ice hopper. An ice auger is housed inside the ice trough. The ice auger transports ice to an ice delivery chute. A hatch is positioned beneath the ice delivery chute, upon which the bag rests while filling. The ice delivery chute and the hatch define a bag filling area such that, when bags are present in the bag filling area, the bags are positioned to be filled. A scale is positioned on the hatch. The scale weighs the ice being deposited into the bag. When the bag is full, the bag is sealed by a sealer. When the bag is sealed, the hatch opens and the bag of ice is deposited in an bag depository. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Pallet bag gathering apparatus to gather pallet bags for use in an automated pallet bag packaging system, preferably for the packaging of fruits or vegetables. The pallet bag gathering apparatus may be automated, semi-automated or manual in nature.

A method for manufacture and filling with a sterile liquid of a tubular packaging includes: providing a container with liquid therein, providing a tube, filling the tube with the liquid from the container, dividing the tube into tubular segments by successive welding operations, and separating the tubular segments at the welded seams. After each welding operation the tube is displaced over a distance corresponding to a desired length of the tubular segments, or multiple thereof. During each welding operation pressure can be exerted locally on and energy can be supplied to the tube. Exertion of pressure and the supply of energy can be staggered in time. During each welding operation a temperature at the welded seam can be kept constant. During each welding operation a welding parameter can be measured, and the welding operation can be controlled on the basis of the measured value of the welding parameter.

The present invention relates to a method for gathering-up a tubular film portion on at least two gathering fingers of a packaging machine and to a gathering apparatus of a packaging machine for carrying out the method as claimed in the invention. The method is distinguished in that the tubular film portion is expanded at least in a part region when being gathered-up onto the gathering fingers. The gathering apparatus as claimed in the invention is distinguished in that the gathering fingers can be driven into a gathering-up position for gathering-up the tubular film portion, in which gathering-up position the tubular film portion is expanded at least in a part region.
