Abstract:
Packaging apparatus for producing encased products from flat-roll stock using an external user interface (i.e., a handle that is external to a housing holding the heat seal assembly that is attached to a horizontally oriented shaft that rotates a first gear in the housing to rotate an aligned second gear in the housing or an electronic control) that is attached to and/or in communication with (directly or indirectly) a heat-seal assembly with a heat-seal contact member, such as a heat-seal band, in the housing to allow a user to adjust a vertical height of the heat-seal assembly while the apparatus is operational and/or without requiring physical access to the interior of the housing.
Abstract:
Apparatus and methods are provided for making one or more tubular components of medical catheters or other tubular bodies using a strip of polymer material including a length, a width, and a first surface including a lubricious or other coating or surface modification. The strip is directed adjacent an elongate mandrel, such as beading, such that the length of the strip extends along the mandrel and the coating is disposed towards the mandrel. The strip is rolled at least partially around the mandrel such that the coating or surface modification is disposed inwardly towards the mandrel, and one or more strip-constrainment members are wrapped around the rolled strip. The directing, rolling, and wrapping steps may be substantially continuous to create one or more strip-mandrel-constrainment member subassemblies.

Abstract:
Apparatus and methods are provided for making coated liners and/or tubular devices including such coated liners. A sleeve may be provided that includes an outer first surface and an inner second surface extending between first and second ends thereof, and a hydrophilic or other coating may be applied to the first. The coated sleeve may be cut between the first and second ends to create opposing edges extending between the first and second ends, and the cut sleeve may be reversed such that the coated first surface defines an inner surface and the opposing edges are disposed adjacent one another, thereby providing a coated liner. Optionally, a tubular structure, e.g., one or more reinforcing layers and/or or outer layers may be attached around the coated liner, thereby providing a tubular device including an inner surface with a desired coating.

Abstract:
A bag making and packaging machine includes a conveying unit, a transverse sealing mechanism, and a gusset forming mechanism. The conveying unit is configured and arranged to continuously convey a tubular packaging material. The transverse sealing mechanism has a pair of sealing jaws configured and arranged to revolvingly move while following annular loci to seal the tubular packaging material in a transverse direction with respect to a conveyance direction of the tubular packaging material. The gusset forming mechanism has a pair of folding members configured and arranged to be pressed against side portions of the tubular packaging material to form gussets in the side portions of the tubular packaging material while the folding members move along the conveyance direction of the tubular packaging material before the transverse sealing mechanism seals the tubular packaging material.
Abstract:
The invention relates to a method for producing a composite film (15; 15a; 15b; 15c) for a tubular bag (1), wherein the composite film (15; 15a; 15b; 15c) consists of a plurality of layers (16; 16a; 16b, 17, 18; 18a, 23, 24; 24a, 25; 25a; 26, 27; 29) that are interconnected, wherein at least one of the layers (16; 16a; 16b, 17, 18; 18a, 23, 24; 24a, 25; 25a; 26, 27; 29) is designed as a barrier layer (16; 16a; 16b, 17, 18; 18a; 27; 29), and wherein at least one further layer (23, 24; 24a, 25; 25a, 26; 29) is provided that has a recess (30; 30a). According to the invention, the composite film (15; 15a; 15b; 15c) is produced by connecting a first layer structure (19) to a second layer structure (22; 22a), the second layer structure (22; 22a) comprises the at least one further layer (23, 24; 24a, 25; 25a, 26; 29), and the recess (30; 30a) in the at least one further layer (23, 24; 24a, 25; 25a, 26; 29) is produced prior to the connection to the second layer structure (22; 22a) in the second layer structure (22; 22a).
Abstract:
The invention relates to a process for manufacturing plastic packaging in tubular form, which process comprises a wrapping step during which a laminate (11) is wrapped, an abutting step during which the edges (8, 9) of the laminate (11) are butted together and a fastening step during which said edges (8, 9) of the laminate (11) are welded together, characterized in that a bead (12) of plastic in the molten state is extruded and deposited on the internal face of the packaging so as to cover at least the weld zone (10) defined between the edges. The energy needed to produce the weld (10) comes from the plastic bead (12).The invention also relates to packaging obtained from the aforementioned process and to a device for implementing said process.
Abstract:
A tubular bagging machine includes an innovative indentation-forming device and a modified cross-sealing device. The innovative indentation-forming device includes two punches that form two indentations in the foil web. The machine then forms the foil web into a foil tube with the indentations aligned directly opposite each other and bowed outward. The cross-sealing device includes two opposing sealing jaws each having a blank formed in it. The jaws are closed together to form transverse seal zones in the foil tube. The blanks are aligned with each other and receive the aligned indentations so that they are not sealed together, resulting in the formation of an air bubble in one of the seal zones. Also disclosed are methods of manufacturing the bags, bags produced by the disclosed machines and methods, and retrofit kits for upgrading existing tubular bagging machines.
