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.

The invention relates to a plastic bag, in particular an FFS bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which bound a bag interior, wherein at least one bottom comprises a weld seam, which extends between the side edges and touches the side edges, and venting openings in the first and/or in the second wall for venting the bag interior, characterized in that at least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed by at least two parallel fastening strips and by a cover strip, wherein the cover strip likewise comprises venting openings and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall between the parallel fastening strips or the cover strip and/or the parallel fastening strips consist of stretchable material.

A method and apparatus for producing product packages comprises operating first and second feedback control loops where product package weight is averaged and used to determine one of two possible adjustments to change the product fill rate and the volume of the product. The feedback loops operate in one of a plurality of index levels. The first feedback loop seeks to improve performance by making adjustments to the fill rate and volume of the product, while incrementally moving to more stable index levels requiring tighter tolerances and package weight averages based on more product packages. The second feedback loop seeks to preserve stability by making its own adjustments to the fill rate and volume of the product if large product package weight fluctuations are sensed. The second feedback loop can move operation to less stable index levels having wider tolerances and package weight averages based on fewer product packages.

An apparatus and method for filling bulk materials into open-mouth bags is provided, which includes the following steps: a) an open-mouth bag is placed beneath a filling spout of a filling station; b) the filling spout is lowered and the open-mouth bag is appended to the filling spout; c) the filling spout with the appended open-mouth bag travels upwardly so that the bottom end of the open-mouth bag is freely suspended; and d) the filling process is started and bulk material is introduced into the open-mouth bag so that the freely suspended bottom end of the open-mouth bag unfolds.

A packaging apparatus with an improved pinch roller apparatus, fluid supply apparatus, and/or a sealing apparatus. The pinch roller apparatus (e.g., comprising one or more guide and/or pinch rollers) is used to deliver film material to the fluid supply apparatus (e.g., nozzle and blower apparatus, or the like) that fills one or more chambers of the film material with fluid (e.g., air, gas, or other like fluid), and the film material is then sealed by a sealing apparatus (e.g., using one or more heating elements with an improved temperature sensor configuration) that seals the fluid within the one or more chambers in order to form the inflated article (e.g., inflated packaging material). In particular, the sealing apparatus provides improved sealing through the improved accuracy of the temperature reading in the heating zone, in part, by locating a sensor between a heating element and a protective member that covers the sensor.

Shown and described are a packaging machine and a method for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright packaging sleeves, and an outer packaging. It is provided that the packaging machine comprises at least one conveyer unit for conveying the packaging sleeve group in a conveyor direction perpendicular to the longitudinal extent of the packaging group and at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, and in that, seen in the conveyor direction behind the sheet material in the base position, a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group.
