[Problem] To provide an apparatus for bonding separators in electrical devices wherein even if a unit that performs bonding using ultrasound is used in assembly-line equipment, the amount of space taken up by said equipment can be kept small. [Solution] The present invention is an apparatus 100 for bonding separators in electrical devices, which is used to bond a pair of separators 40 to each other so as to sandwich an electrode 20, provided with an oscillator 153 that generates ultrasonic oscillations; a booster 152 that amplifies the generated oscillations; a horn 151 that applies the amplified oscillations to the pair of separators so as to bond said separators to each other; and separator conveyance units 120, 130 that convey the pair of separators to a bonding position where the horn bonds said separators to each other, wherein the oscillator, the booster, and the horn are laid out in a plane that is parallel to the direction X in which the separators are conveyed and perpendicular to the surfaces of the separators, or the oscillator and the booster are laid out closer to the widthwise centers of the separators than the horn is when seen from a direction that is parallel to the direction in which the separators are conveyed.

摘要:
A method of producing packages from a tube of packaging material for a liquid food product, comprises reforming a flat web of packaging material into a cylindrical tube, feeding the tube of packaging material in first direction, filling the tube with a liquid food product, transversally sealing the tube, at regular intervals, into separate package volumes, wherein a longitudinal axis of every second transversal seal being parallel to each other, and a longitudinal axis of each adjacent transversal seal being perpendicular to each other, and wherein a longitudinal axis of each transversal seal is angled in a range between 15-30° in relation to a plane which is orthogonal to the longitudinal axis of the tube of packaging material. Also disclosed is a packaging material for use in the method, a package produced with the method, and a filling machine performing the method.
