In a weighing and packaging system 1, an analysis unit 714 ascertains a fluctuation tendency in a time series for a measured value of information pertaining to a time in which a group of articles C passes between a light-projecting unit 27a and a light-receiving unit 27b of a detection sensor 27 of a bag-making and packaging unit 3, and adjusts a transverse seal timing or a cycle time in accordance with the fluctuation tendency. As a result, articles can be prevented in advance from being bitten during transverse sealing.

A method for separating portions of a food mass (3) from a film tube (1), which is continuously advanced along a tube-conveying path (9) at belt-running speed and is filled with the food mass, in particular with processed cheese (3), wherein the film tube filled with the food mass (2) is initially formed into a band of defined thickness by means of a pair of calibrating rollers, and wherein, in order to form separate food portions (3), the food mass is then displaced, by means of a pair of displacement rollers acting upon one another, out of displacement regions (2) extending transversely across the film tube, wherein the displacement rollers are driven by means of a drive, which is controllable in terms of the running thereof, in a manner decoupled from the belt-running speed.

A form fill seal apparatus for forming and filling a plurality of bags with a product having a tube formation assembly forming a tubular film, a bag forming assembly configured to form transverse seals and to cut the tubular film to form bags. A product delivery system is provided to deliver product from a positive displacement pump to a product delivery tube. A control system is structurally configured to direct the positive displacement pump to operate in two different modes, a first, continuous operating mode and a second, dosing operating mode. A method of filling is likewise disclosed.

A system includes a first horn, a first ultrasonic transducer, a second horn, a second ultrasonic transducer, a memory, and a controller. The first horn includes a first part-interfacing surface. The second horn includes a second part-interfacing surface and is positioned relative to the first horn such that a part to be welded can be positioned between the first and second part-interface surfaces. The controller is configured to cause a first ultrasonic energy to be applied through the first horn via the first transducer to cause the first part-interfacing surface to vibrate, cause the first horn to move in a first direction at a first time, cause a second ultrasonic energy to be applied through the second horn via the second transducer to cause the second part-interfacing surface to vibrate, and cause the second horn to move in a second direction at the first time.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.
