Abstract
A bag for producing a foam-in-bag dunnage material comprises a closed edge portion and, in a non-sealed state of the bag, an open edge portion, the closed and open edge portions delimiting an inner bag volume. The invention proposes that a bag structure of the bag comprises a mixing chamber which is adapted to receive foam precursor substances, which is arranged within the inner bag volume, which is at least partially and initially delimited against the remainder of the inner bag volume, and which in the non-sealed state of the bag is connected to the open edge portion.
Claims14
Bag for producing a foam-in-bag dunnage material, comprising a closed edge portion and, in a non-sealed state of the bag, an open edge portion, the closed and open edge portions delimiting an inner bag volume, wherein a bag structure of the bag comprises a mixing chamber which is adapted to receive foam precursor substances, which is arranged within the inner bag volume, which is at least partially and initially delimited against the remainder of the inner bag volume, and which in the non-sealed state of the bag is connected to the open edge portion.
Machine for producing a foam-in-bag dunnage material, comprising a feed device for feeding a bag to an injection device adapted to inject foam precursor substances into the bag and a mixing device which is adapted to provide a mixing action onto an exterior surface of a bag after injection, wherein the injection device can be arranged during injection in an injection section and wherein the mixing device can be arranged in a mixing section during the mixing action, wherein the mixing section is arranged, seen in a feed direction, downstream from the injection section, and wherein the feed device is adapted to move the bag such that a mixing chamber of the bag, after injection, moves from the injection section to the mixing section, wherein the injection device is movable and is arranged to inject the foam precursor substances into the mixing chamber of the bag, the mixing chamber being delimited against the remainder of the bag, wherein the mixing device is separate from the feed device and is adapted to only act on the foam precursor substances comprised within the mixing chamber of the bag.
