A method for manufacturing a rectangular-bottomed packaging bag includes an unfolding step of unfolding a flat bag by separating a pair of opening/closing plates (13) inserted into the flat bag from each other in a thickness direction of the flat bag, and a gusset forming step, after the unfolding step, of forming a side gusset and a bottom gusset by thrusting folding plates (11 and 12) between the pair of opening/closing plates (13) from the outside of the bag toward the inside of the bag.

A method includes separating a portion of a flattened tube of stock packing material to a custom length to form a pouch pre-form and closing a first end of the pouch pre-form leaving a second end of the pouch pre-form open. The method can include placing product into the pouch pre-form and closing the one open end of the pouch pre-form to form a closed pouch containing the product.

A dosing apparatus for a machine for producing unit dose articles including first and second dosing units each having: a nozzle support body carrying a plurality of nozzles, and a movement control unit configured for moving the respective nozzle support body along a closed-loop path, wherein the movement control units of the first and second dosing units are configured for moving the respective nozzle support bodies independently of each other along the closed-loop path.

An adjustable pouch machine comprises a vertical sealer module forms transverse seals between two plies of a pouch web to partially define a plurality of pouches. Rollers selectively tension and relax the web on the vertically oriented wheel, allowing them to drop away from heated lands on emergency and cycle stops. A filler wheel has a plurality of adjustable gripper units mounted directly thereon for transporting independent separate pouches cut from the pouch web. An adjustable knife is selectively provided with changeable knife hub sets to handle a variety of pouch sizes where a filler wheel alternately first fills and seals pouches in a train. Gear linkage accommodates variation in distance between hubs of different sets. Various embodiments, apparatus and methods are described.

A movement unit for articles includes a first carousel device having a first transporter member and first gripping heads mounted thereon and provided to move the articles into a single-row configuration. The movement unit further includes a second carousel device to receive the articles from the first carousel device, having a second transporter member and second gripping heads mounted thereon. Each second gripping head is configured to receive the articles from a respective first gripping head and to move the articles into a multi-row configuration.

A rotary filling machine for filling containers with bridgeable dry materials includes a turret supporting a plurality of circumferentially spaced drop buckets and a plurality of funnel assemblies located under the drop buckets. A stationary slide plate is located vertically between the funnel assemblies and the drop buckets. The slide plate is configured such that flow paths from the bottoms of the drop buckets to the inlet openings of the funnel assemblies increase progressively in at least a portion of a circumferential extent of the slide plate. Drop buckets are located above the slide plate and rotate with the turret. Each drop bucket is provided with one or more partitions that hinder the “snow-plowing of particles” along the edge of the associated fill opening in the machine’s fill plate rather than the sweeping of those particles into the fill opening.
