The embodiment provides a heat-sealing apparatus and a method of accurately controlling heat sealing temperature by measuring the temperature using a heat-sealing apparatus which heat-seals a pair of heat seal materials by nipping them between a pair of heating bodies. The method of heat-sealing includes mounting a cover material on the surface of at least one of the heating bodies to be in contact with the heat seal material, attaching a minute temperature sensor to the surface of the cover material on the side to be in contact with the heat seal material, and controlling temperature of welding face by the temperature detected by the minute temperature sensor, and an apparatus therefor.

An exemplary air cushion inflation machine includes: a first terminal connected to a direct current input; a second terminal; a reference resistor powered by the direct current input; an op-amp; and a transistor. The first terminal of the op-amp is connected to a variable voltage source and the second terminal of the op-amp is connected to the reference resistor. The transistor has a base connected to an output of the op-amp, an emitter connected to the reference resistor, and a collector connected to a first terminal of a sealing band apparatus having first and second terminals. A meltable material placed between the first and second terminals is melted by resistance of current flowing between the first and second terminals. The variable voltage source changes voltage based on a voltage drop measured across the first and second terminals by a voltage measurement device and the constant current.

The device according to the invention allows a more economical production of a packaging unit comprising a pouch in the wrapping and has a trough-shaped recess in which a helically laid heating conductor is accommodated.

A system for consolidating materials, comprising a sonotrode configured to direct ultrasonic energy into materials to be consolidated, wherein the materials to be consolidated have both a glass transition temperature and a melting temperature; a non-rigid consolidating material in proximity to the sonotrode, wherein the non-rigid consolidating material and sonotrode define a region therebetween for receiving the materials to be consolidated, and wherein the non-rigid consolidating material has a glass transition temperature that is higher than the glass transition temperature of the materials to be consolidated and a melting temperature that is higher than the melting temperature of the materials to be consolidated.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

The invention relates to an apparatus and to a method for establishing a connection having material continuity or having material continuity and shaping matching or for separating such a connection of at least one metal or ceramic component and of a component formed from or by a thermoplastic polymer in which the components to be joined together can be pressed together by a pressing device having a counterholder and a plunger. A heating device is present at the plunger and/or at the counterholder or acts there. A heating of the at least one metal or ceramic component up to above the softening temperature of the component formed from or by polymer can be achieved with the heating device, with the heating device being having at least one electrical resistance heating element that is covered by an electrically insulating, preferably ceramic, protective film, and/or having at least one laser beam that is directed to the metal component(s) within the joining region, and/or having at least one inductor present at the plunger and/or at the counterholder for the inductive heating of the meal component(s).

There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.

A heating block assembly including one or more configurable insulator segments and a heater block having a first surface configured to removably receive the one or more configurable insulator segments, in which each of the one or more configurable insulator segments covers only a portion of the first surface. A method for sealing at least one portion of a package using such a heating block assembly is also disclosed.

A process for forming a container from a blank, the process comprising the steps of: thermally inducing one or more fold lines on at least one surface of a container blank fabricated from a thermal insulation sheet material, wherein the blank comprises: a first panel portion; a second panel portion located adjacent the first panel portion and sharing a first common edge therewith; and a third panel portion located adjacent the second panel portion and sharing a second common edge therewith, the second common edge being substantially parallel to the first common edge, wherein the first panel portion and the third panel portion are each associated with a pair of flap members adapted for folding movement relative to the respective first and third panel portions such that, when assembled, each of the flap members overlies an edge of the second panel portion substantially perpendicular to the first common edge and the second common edge, folding the first panel portion of the container blank along a first fold line, wherein when folded, the first panel portion is substantially perpendicular to the second panel portion of the container blank; folding the third panel portion of the container blank along a second fold line, wherein when folded, the third panel portion is substantially perpendicular to the second panel portion and substantially parallel to the first panel portion; sealing a portion of each of the pair of flap members of the first panel portion to a portion of each of the pair of flap members of the third panel portion to form a side seam joint; and sealing a portion of the first panel portion adjacent the side seam joint and a portion of the third panel portion adjacent the side seam joint to an edge of the second panel portion to form a bottom seam joint.

A machine converts a web of preformed pouches, which are defined by transverse seals extending from a remote edge, into inflated dunnage units. A sealing arrangement is positioned to provide a longitudinal seal intersecting the transverse seals to close the preformed pouches and form a dunnage unit. The sealing arrangement has at least two sealing belts. Each belt is positioned so that respective first sides engage a surface of the web and pull the web through sealing elements positioned on either side of the web. A heating element is on a second side of the first belt not engaging the web. A compliant material is on a second side of the second belt not engaging the web. As the web passes between the heating element and compliant material, imperfections in the web are smoothed by the compliant material and the layers of the web are sealed by the heating element.
