The present invention provides an apparatus for receiving and processing containers by conducting a plurality of processing steps, the apparatus comprising a plurality of processing stations, wherein the apparatus is configured such that a processing step is conducted at each processing station, wherein the plurality of processing stations comprises an infeed station for receiving the containers; a filling station for filling the containers with a product; and an output station for dispensing the filled containers; wherein the apparatus is configured to move the containers through the plurality of processing stations in a rotary manner about a substantially horizontal central axis.

A fluid manifold system includes a first manifold having portions of opposing flexible sheets welded together to form a fluid flow path therebetween, a fluid inlet communicating with the fluid flow path. The fluid flow path of the first manifold includes: a primary flow path communicating with the fluid inlet of the first manifold; and a plurality of spaced apart secondary flow paths that branch off of the primary flow path. Each secondary flow path has a first end communicating with the primary flow path and an opposing second end, each secondary flow path having a diameter that is smaller than a diameter of the primary flow path. The fluid manifold system also includes a plurality of tubular connectors with each tubular connector being secured to the first manifold at the second end of a corresponding one of the secondary flow paths.

Sealed packaging for a confectionery product Food product packaging comprising a food product (P) in a sealed wrapper of sheet material, comprising a first sheet (2) shaped in a receiving configuration adapted to contain the product, having an end edge in the shape of a flange (4) and a second sheet (6) adhered to said flange (4) to form a sealed wrapper surrounding the product (P), comprising a body of sheet material (8) in the shape of a cup with a base (10) and a side wall (12), where the base (10) is made to adhere to said second sheet (6) and the adhesive force between said base (10) and said second sheet (6) is greater than the adhesive force between the second sheet (6) and said flange (4), so that a force tending to separate said body from the packaging causes the detachment of said second sheet (6) from the flange (4) with the opening of the packaging.

The present invention relates to a machine for filling bags with a granular product comprising a filling station, a welding station, and a cooling station. The machine comprises a supporting device for supporting the bags below the stations. The device comprises a supporting surface assembled in a pivoting manner on a pivot shaft, and actuating means. The supporting surface has a first supporting segment for supporting the bags of the filling and welding stations on one side of the pivot shaft and a second segment for supporting the bag of the cooling station on the opposite side of said pivot shaft. The supporting surface can pivot in an alternating manner around said pivot shaft for moving the base of the bag which, in operation, is located in the filling station during filling. The invention also relates to a filling method.

A method for transversally sealing a packaging material tube, comprises placing a transversal sealing section of the tube between a sonotrode and an anvil. The transversal sealing section comprises a first two-layer sub-section, a three-layer sub-section and a second two-layer sub-section, transmitting ultrasonic acoustic vibrations, having a frequency and an amplitude, from the sonotrode into the transversal sealing section, thereby melting the plastic foil in the transversal sealing section, and pressing the tube together between the sonotrode and the anvil to bond the plastic foil such that transversal sealing is formed. The anvil has a ridge comprising various sub-sections for receiving various ones of the sub-sections of the tube, wherein the ridge has equal height in at least some of the sub-sections. The frequency, amplitude, pressure and paperboard properties are chosen to achieve equal temperature in the first two-layer sub-section, the three-layer sub-section and the second two-layer sub-section.
