Described is a compensating device applicable on intermittent advancement packaging machines with wrapping material constituted by a film made of a flexible plastic material, for continuous compensating of a stretching of the film during drawing thereof, the machine comprising a first drawing group of the film, a mobile element able to exert a determined force on the film during advancement, the mobile element being conventionally known as a dancer and a second drawing group of the film arranged downstream of the first drawing group, where each drawing group is provided with a sensor for detecting markers located at regular intervals along the film, the compensating device being constituted by a third drawing group, located between the first and second drawing groups, the third drawing group being provided with a marker sensor, the third drawing group being provided with independent motorisation and an automatic roller opening system.

A packaging apparatus for small piece goods, the use of the packaging apparatus, and a method for producing a blister tube are provided. The packaging apparatus includes a packaging material guiding device for providing a shaped packaging material web suitable for receiving small piece goods, a longitudinal joining device which is arranged downstream of the packaging material guiding device and a transverse joining device which is arranged downstream of the packaging material guiding device. The transverse joining device joins the shaped packaging material web together at predetermined intervals transversely to the direction of travel to form a transverse joining area. The transverse joining device includes two joiners, a first joiner having a plurality of embossers that are individually movable transversely to the direction of travel and are arranged so that they can be extended from the first joiner and retracted into the first joiner.

A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device comprises two opposing sealing elements between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first transverse seal of the tube. It further comprises two volume control elements. The forming device is characterized in that it is arranged to displace the first transverse seal off-center in relation a longitudinal axis of the first portion of the tube in a displacement direction essentially perpendicular to the first transverse seal to enable later shaping of a corresponding final package with a wall arranged with a predetermined angle of inclination in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.

A vertical flow-wrapper, which produces packages from a packaging material, the vertical flow-wrapper includes: a form-fill tube, a form shoulder, a longitudinal-sealing means, a cross-sealing means/cutting means, and means to attach a reclosure means to the packaging material, the form shoulder is an asymmetrical form shoulder and the means are at least partially provided within vertical boundaries of the asymmetrical form shoulder.

A vertical flow-wrapper with a form-fill-tube along which a film is transported in a transport direction and formed into a tube, a longitudinal-sealing means, which seals two opposing longitudinal ends of the formed film together to a longitudinal seal, and a cross-sealing means and a cutting means which provide cross seals to each package and separate the packages from each other and means to apply re-closure means to each package, arranged parallel to the longitudinal seal and as individual segments.

A tubular bag includes a top side and a bottom side running parallel to the top side and further has a first seam running parallel to the top side and to the bottom side. The first seam is produced by bonding, and the tubular bag includes at least two lateral second seams connecting the top side to the bottom side. The second seams are produced by bonding, wherein a flap is formed on and/or in the first seam. Furthermore, a method is provided for producing the tubular bag and a packaging machine is provided for carrying out the method.

A tubular bag includes a top side and a bottom side running parallel to the top side, the tubular bag further having a first seam running along the top side, along the bottom side, or parallel to the top side and to the bottom side. The first seam is produced by bonding. The tubular bag includes at least two lateral second seams connecting the top side to the bottom side. The second seams are produced by bonding. A flap is formed on the outside parallel to the first seam. Furthermore, a method is provided for producing the tubular bag and a packaging machine is provided for carrying out the method.
