Thermal curing of a potting material within a hole in a surface of a composite material is described utilizing a flexible vacuum compression device that includes a chemical-based heating pack. The vacuum compression device includes an internal compartment within a cavity that retains the chemical-based heating pack, and a vacuum port having a passage into the cavity. An end of the vacuum compression device includes an interface that forms an air-tight seal between the cavity and the surface when applied to a surface of the composite material. Drawing a vacuum via the vacuum port collapses the vacuum compression device and positions the chemical-based heating pack proximate to the surface, enabling heat from the chemical-based heating pack to thermally cure the potting material.

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.

A method of forming a three-dimensional object, is carried out by (a) providing a carrier and a build plate, the build plate comprising a semipermeable member, the semipermeable member comprising a build surface with the build surface and the carrier defining a build region therebetween, and with the build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface, (c) irradiating the build region through the build plate to produce a solid polymerized region in the build region, while forming or maintaining a liquid film release layer comprised of the polymerizable liquid formed between the solid polymerized region and the build surface, wherein the polymerization of which liquid film is inhibited by the polymerization inhibitor; and (d) advancing the carrier with the polymerized region adhered thereto away from the build surface on the build plate to create a subsequent build region between the polymerized region and the build surface while concurrently filling the subsequent build region with polymerizable liquid as in step (b). Apparatus for carrying out the method is also described.

The present disclosure is directed to a compression belt for inflation and sealing devices. The device may include an inflation assembly, a heating assembly, and a drive mechanism. The inflation assembly may direct fluid between first and second overlapping plies of a flexible web material to inflate chambers between the plies. The heating assembly may be operable to heat the first and second plies of the web material to create a longitudinal heat seal that seals the fluid in the inflated chambers. The drive mechanism may drive the web material in a downstream direction. The drive mechanism may tension the web material against the heating assembly. The drive mechanism may include a first belt including a high grip material on a surface that contacts the web material to grip the web material during heating by the heating assembly.

A joining apparatus includes a fusing mechanism part that joins two thermoplastic sheet-like materials by fusing, a sticking mechanism part that sticks an adhesive tape along a joined portion of the sheet-like materials, a workbench having a placement surface on which the fusing mechanism part and the sticking mechanism part are disposed side by side, the placement surface allowing the sheet-like materials in an unfolded state to be placed thereon, and a guide that allows an end portion to be joined of one of the sheet-like materials and an end portion to be joined of the other sheet-like material to overlap each other while aligned along a plane intersecting the placement surface, each of the end portions to be joined of the sheet-like materials being placed on the placement surface, and to feed the overlapping end portions to be joined. The fusing mechanism part fuses and joins the end portions.
