A welder for joining two polymeric sheets together using a wedged heating element allows for a heating profile on opposite faces of the heating element to be varied by controlling where each of the polymeric sheets contacts the corresponding face.

Method for Detecting the Making or Breaking of Contact of a Sonotrode with a Counter-Element
20220075341 · 2022-03-10 ·

The present invention concerns a method of detecting the making or breaking of contact of a sonotrode (4) which is caused to vibrate with a frequency f and a vibration amplitude A.sub.0 with a counterpart element (5). To provide a method with which contact-making or breaking of a sonotrode with a counterpart element can be particularly quickly and inexpensively detected it is proposed according to the invention that the method has the following steps: a) recording a time configuration of the vibration amplitude A.sub.0 (1) during a first measurement time interval ΔT, and b) determining from the time configuration of the vibration amplitude A.sub.0 (1) whether making or breaking of contact occurred within the measurement time interval ΔT.

Manufacturing of polyethylene thin films for high-altitude balloons

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.

END SEAL CARRIAGE VELOCITY DIFFERENTIAL

A form-fill-seal system includes a tube feeding system, an end seal carriage (420), and a computing device. The tube feeding system feeds a tube (410) of flexible material at a first velocity (v1). The computing device controls the end seal carriage (420) to cause an increase in a velocity of the end seal carriage to substantially the first velocity (v1), a start of a dwell time of the end seal mechanism (424, 422) on the tube (410) of flexible material while the velocity of the end seal carriage is at substantially the first velocity (v1), and an increase in the velocity of the end seal carriage to a second velocity (v2) during the dwell time. The end seal mechanism cuts a package (440) from the tube during the dwell time. The increase in the velocity of the end seal carriage to the second velocity (v2) results in an increased distance of the package from the tube.

METHOD AND APPARATUS FOR MAKING BAGS

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.
