Packaging apparatus comprises two counter-rotatable sealing dies for pressing together two tissue webs to produce pockets for containing a substance for preparing beverages and to seal around said pockets, and two heating drums for heating the sealing dies and each being positioned inside a respective sealing die, wherein a first heating zone of each heating drum comprises a first plurality of circumferentially distributed infrared heating elements, and a second heating zone of each heating drum comprises a second plurality of circumferentially distributed infrared heating elements.

Systems and methods of controlling outputs of infrared heaters used to join a first part to a second part, and a component made thereby. Upper and lower nests hold the first and second parts, respectively. A movable heating platen has infrared heaters on opposite surfaces. Imaging sensors have fields of view encompassing heated portions of the first and second parts, respectively, when the platen is retracted away from an area between the upper and lower nests. A controller causes the upper and lower nests to move while causing the platen to extend into and retract away from the area between the upper and lower nests. The first imaging sensor takes a first image of the heated portions of the first part, which causes an adjustment to be made to an output of the infrared heaters in a subsequent welding cycle.

An induction cooking system includes a first container that receives first contents and a second container sized to fit within the first container. The second container is composed of a ferromagnetic material such that the second container is heated in response to received electromagnetic radiation. An exterior surface of the second container is in contact with the first contents of the first container, and an interior surface of the second container is in contact with second contents placed within the second container.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool. The second joining tool is heated or cooled by a temperature unit. The temperature unit is inactive during each of the plurality of ultrasonic joining operations.

A packaging machine including a hot plate assembly adapted to fuse a length of heat-sensitive film wrapped around a package. A controller is adapted to calculate a time period the heating element is energized to fuse the length of heat-sensitive film wrapped around the package based on an initial temperature of the heating element. A hot plate status indicator is adapted to indicate at least to different statuses of operation of the packaging machine.

An apparatus to join two panels together includes a chamber, a horn positioned within the chamber, the horn moving reciprocally within the chamber, and a set of heating elements positioned about the horn to heat the horn. One of the panels has a post molded to it, the post extending through the other panel, and after the horn is heated an end of the horn is placed on top of the post and is ultrasonically vibrated to form a head of the post to join the two panels together.

The utilization of heat in the manufacturing of footwear may be accomplished through microwave energy. The microwave energy is conveyed to the footwear components through a microwave transparent window of a tool. The microwave transparent tool window forms as least a portion of a part-contacting surface of the tool. Another surface of the tool is formed from a microwave reflecting material, such as aluminum. The footwear component(s) are exposed to microwave energy while within the tool such that the microwave energy passes through the tool window to cause a dielectric heating of one or more materials within a tool cavity of the tool.

The present disclosure relates to a method for curing a heat-curable material (1) in an embedded curing zone (2) and an assembly resulting from such method. The method comprises providing a heat-conducting strip (3) partially arranged between a component (9) and a substrate (10) that form the embedded curing zone (2) therein between. The heat-conducting strip (3) extends from the embedded curing zone (2) to a radiation-accessible zone (7) that is distanced from the embedded curing zone (2) and at least partially free of the component (9) and the substrate (10). The method further comprises irradiating the heat-conducting strip (3) in the radiation-accessible zone (7) by means of electromagnetic radiation (6). Heat (4a) generated by absorption of the electromagnetic radiation (6) in the heat-conducting strip (3) is conducted from the radiation-accessible zone (7) along a length of the heat-conducting strip (3) to the embedded curing zone (2) to cure the heat-curable material (1) by conducted heat (4b) emanating from the heat-conducting strip (3) into the embedded curing zone (2).
