Aspects of the disclosure relate to manufacturing a balloon envelope for use in a stratospheric balloon system. For instance, a stream of polyethylene mixture us extruded through an extruder in order to orient molecules of polymer chains of polyethylene and to provide an oriented film. The oriented film is passed through an electron beam and thereby crosslinking the polymer chains to provide a cross-linked film. The cross-linked film is heat sealed to form the balloon envelope.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

A method is provided for producing a common connecting opening in two components, at least one of which is made from a plastically deformable material. In the method, at least the edge region of a first prefabricated opening of the first component is softened in order subsequently to introduce a mandrel which displaces the material softened by the heating so that a common connecting opening having a predetermined diameter is obtained.

An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and anvil. The anvil is positioned close to the horn. The horn or anvil has a face that is rotatable about a rotation axis. The face has a raised profile, and a height thereof has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn/anvil. A tapered bonding profile, a traction pattern, and a cut-and-seal feature are also disclosed.

A method for handling containers (I) of collapsible type in a filling machine (20) comprising consecutively arranged stations (S1, S2, S3, S4, S5, S6) comprising a filling station (S3) and a gas filling station (S5), the method comprising intermittently moving the containers (I) to the consecutively arranged stations (S1, S2, S3, S4, S5, S6), supplying, at the filling station (S3), liquid product into the product compartment (5) and supplying, at the gas filling station (S5), gas into the handle compartment (7). The filling station (S3) and the gas filling station (S5) are operated such that liquid product is supplied to the product compartment (5) of one of the containers (I) while gas is supplied to the handle compartment (7) of another of the containers (I). The step of supplying gas at the gas filling station (S5) comprises providing a first gas flow (Qi) at a first pressure (Pi) and delivering said first gas flow (Qi) from the nozzle (30) to the handle compartment (7) via said inlet (11), and subsequently providing a second gas flow (Q.sub.2) at a second pressure (P.sub.2), lower than said first pressure (P.sub.1), and delivering said second gas flow (Q.sub.2) from the nozzle (30) to the handle compartment (7) via said inlet (11) for establishing a target pressure (P.sub.T) inside said handle compartment (7) corresponding to said second pressure (P.sub.2).

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.

An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.
