Device for manufacturing cushions filled with a gaseous medium from
synthetic tubular foil. The device comprises supply means for supplying
flexible tubular foil in a supply direction, perforation means situated at
a first station for making a row of perforations in the tubular foil,
introduction means situated at the first station for introducing a gaseous
medium, and sealing means situated at the first station for making a
transverse seal on either side of the row of perforations for closing off
the tubular foil and sealing off the row of perforations. The supply means
are provided with a plate which can be placed within the tubular foil and
is kept within the tubular foil while the device is operative, which plate
has a top side and a bottom side situated at a distance from it, a first
side wall and a second side wall situated at a distance from it for
keeping the walls of the tubular foil apart, the plate in both main planes
being provided with at least one retaining recess, the retaining recesses
being situated opposite each other, and in which the device is provided
with at least two retaining rollers for abutment in the respective
retaining recesses. The introduction means are provided with at least one
blast pipe mounted on a vise-grip wrench, which vise-grip wrench can be
moved to and from a respective side wall of the plate until in abutment
with the tubular foil, the blast pipe being moveable until in the
continuous opening for making an introduction perforation for introducing
a gaseous medium in the tubular foil.
