An apparatus for filling and sealing bags intended for containing banknotes includes a generally parallelepiped-shaped container, with side walls, a bottom and an upper lid provided with an opening for allowing entry into the container of a bag, made up of flexible plastic film, and of banknotes intended to be introduced into the same bag. The apparatus includes a pair of sealing bars arranged at the upper end of the container and a system for controlling and moving the bars between their respective opening and closing positions. The control and movement system of the sealing bars has a motor for driving a shaft adapted to rotate at least one driving pulley arranged below in correspondence with a vertical edge of the container, a kinematic connection for closing the bars comprised of a combination of cables and tension springs connecting the driving pulley to the sealing bars and a kinematic connection for opening the bars comprised of a combination of cables and tension springs connecting the sealing bars to a respective fixed anchor point of the container.

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.

There is provided a heat sealing device that seals a film for packaging an article by heat welding, with the film sandwiching the article in between and being disposed in a partially overlapped state around the article, the heat sealing device including: a sealing head that heat-welds a seal portion to be sealed in the film; a first cooling head that cools the seal portion after heat welding by the sealing head; and a second cooling head that cools at least a part of an article side region in the film, which is located on an article side with respect to the seal portion.

A free-standing blister pack made by heating molding plastic material, film or sheet, creating a container portion of a fixed space, storing a product such as cosmetic, fragrance, or homecare products in the space, and having a cover sheet attached to a flange of the container portion so as to create a sealing function. The blister packaging has a support structure to hold the blister upright after the removal of the perforation and score feature allowing the product to remain in a free-standing position after assembly.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

An inline packaging machine for automatically accommodating and filling different sized containers, such as pouches, to reduce changeover time and thereby improve operating efficiency of the machine. The machine includes stations disposed longitudinally along a center line of the machine, including a first carrier track opposing a second carrier track with respect to the center line. A first clamp is disposed on the first carrier track and at least a second clamp is disposed on the second carrier track wherein the clamps are configured to releasably secure first-sized pouches for filling. The pouches are advanced inline from a setup station through an opening station to a filling station for filling with contents. The filled pouches are then advanced to a sealing and discharging station. A control system automatically adjusts the distance between the corresponding clamps to accommodate second-sized and/or third-sized pouches for inline processing and filling.

A heater includes: a heat generation unit that generates heat when energized; an electric wire that is attached to the heat generation unit and supplies electric current to the heat generation unit; a ground wire that is attached to the heat generation unit and is grounded; a conductive cover that includes an electrical conductor, is attached to the heat generation unit, and is grounded; and an insulating cover that has an electrical insulating property and at least partially covers the conductive cover.

A radially expansible press plunger has a base plate, a first expansion tool and a second expansion tool. The first expansion tool and the second expansion tool are movable in relation to each other in the axial direction. The first expansion tool has at least one inclined plane surface. The second expansion tool has at least one inclined plane surface corresponding to the at least one inclined plane surface on the first expansion tool. Each inclined plane surface on the first expansion tool contacts and applies pressure to the corresponding inclined plane surface of the second expansion tool when the expansible press plunger is in the radially expanded state. An attachment unit for attaching a container sealing element to a container body and a method for attaching a container sealing element to a container body are also disclosed.
