A material welder for welding at least two portions of a weldable material together, including: a top bar assembly and a bottom bar assembly, a portion of the top bar assembly directly above a portion of the bottom bar assembly, the top bar assembly including a first and second heating element substantially in the same plane and the bottom bar assembly including a first and second heating element substantially in the same plane, at least one heating device adapted to selectively heat the first heating elements and/or second heating elements, an actuator device adapted to move the top bar assembly towards the bottom bar assembly and/or the bottom bar assembly towards the top bar assembly, such that the first heating element of the top bar assembly aligns with the first heating element of the bottom bar assembly and the second heating element of the top bar assembly aligns with the second heating element of the bottom bar assembly; a contact surface of the top bar assembly and a contact surface of the bottom bar assembly adapted to contact the material during a welding process.

The vacuum sealer includes a base, a cover, a vacuuming device, at least a heating device, at least a heat-resistant element wrapping around the heating device, at least a heat insulation element between the base and the heating device, at least a power provision device, and at least a safety breaker device. The safety breaker device includes at least a safety switch, and at least a trigger element. The object to be sealed is placed on the heating device and, as the cover closes the base, the safety switch engages the trigger element to release the safety breaker device and to allow the power provision device to power the heating device. The heat insulation element prevents heat from being conducted to the base. With the dual protection from the safety breaker device and the heat insulation element, safety is enhanced and the power provision device may operate under high voltage.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.
