An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

Various components, such as radio frequency (RF) or thermal reflectors, may be constructed from joining of pre-formed tape. For reflectors, this process may reduce the number of ribs, only require partial ribs, or eliminate the use of ribs altogether. To build such a reflector, a spool of tape, a joining tractor, and a foundation ring may be employed.

A heat seal between a plastic bag and a plastic sheet is used to provide a more secure and reliable seal to define a modified atmosphere for a pallet of perishables. The heat seal reduces atmosphere failures and aids in providing a more consistent atmosphere in the pallet bag system thus reducing the number of pallets that have an out of specification atmosphere. The heat seal may be created with a heating sealing apparatuses that is part of a system used to load and seal a load of containers of perishables onto a pallet. The heat sealing apparatus uses two heated rollers coupled to a rotating arm to contact and heat seal a plastic bag to a plastic seal that enclose a palletized load of perishables that are rotated on a turntable.

Disclosed is an intelligent automatic conical net making machine. The net making machine comprises a net winding device (3) and a net binding device (4). The net winding device (3) comprises a filter screen winding shaft (3.1), a filter screen winding drum (3.3) and a net winding power device (3.2). The filter screen winding shaft (3.1) comprises a conical hollow shaft body, and a strip-shaped net binding hole is axially provided in the hollow shaft body. The filter screen winding drum (3.3) comprises two arc-shaped plates (3.5) hinged together, and the two arc-shaped plates (3.5) can be driven by the net winding power device (3.2) to be opened and closed along a hinged shaft to wrap the filter screen winding shaft (3.1) without shielding the net binding hole. The net binding device (4) comprises an automatic stapler (4.1) and a stapler base mould (4.5), and the stapler base mould (4.5) of the net binding device (4) can be inserted into the hollow shaft body of the filter screen winding shaft (3.1). The automatic stamper (4.1) can cooperate with the stapler bottom mould (4.5) through the net binding hole to complete a net binding operation. The equipment can stably and reliably finish the net supplying, feeding, winding and binding process, is smooth in equipment operation, and is suitable for popularization and industrial production in the industry.

A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

A method of forming a fluid-filled chamber for an article of footwear is provided and includes positioning a first sheet of material and a second sheet of material in a pressure chamber, increasing a fluid pressure within the pressure chamber to a first value, and coupling the first sheet of material to the second sheet of material within the pressure chamber to define a fluid-filled chamber defined by the first sheet of material and the second sheet of material and having a fluid pressure equal to the first value. The method also includes decreasing the fluid pressure within the pressure chamber to a second value.

A method and system for manufacturing a conical shaped acoustic structure. A sheet of acoustical material is cut to form individual pieces using a cutter system. Each individual piece in the individual pieces has a flat pattern for the conical shaped acoustic structure. An individual piece is positioned around a mandrel with a conical shape using an actuator system. Two edges of the individual piece are positioned for joining. The two edges of the individual piece positioned around the mandrel are joined to form the conical shaped acoustic structure.

The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.
