An oral device may include a body. The body may have a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion. The body may further include a first wedge portion provided on a bottom surface of the first side portion, and a second wedge portion provided on a bottom surface of the second side portion. Each of the first wedge portion and the second wedge portion may have a varying thickness.

The present invention discloses a method for manufacturing an artificial leather shoe upper which comprises steps of preparing plural pieces of artificial leather upper material, setting a thermoforming machine, placing the plural pieces of artificial leather upper material in the thermoforming machine, pumping out excess air of a lower die block of the thermoforming machine, thermoforming the plural pieces of artificial leather upper material to obtain a semi-finished product, and demoulding, image recognition, laser cutting and coloring the semi-finished product to obtain the artificial leather shoe upper.

A rubber sole thermos-molding machine includes a lower mold seat disposed on a hydraulic actuator of the machine seat. The lower mold seat ascends and descends with respect to the upper mold seat according to the hydraulic actuator, allowing the lower upper molds to close and open. The upper mold seat moves between a normal and a tilt positions according to the turning mechanism. The middle plate horizontally moves between the upper and the lower mold seats, and has a push mechanism connected with the middle frame. When the pin of the middle frame and the fasten unit on the push mechanism are separated, the middle frame is stacked on the middle plate or the lower mold to move, facilitating the cleansing and material-feeding operations. The user can cleanse the upper mold without being hindered by the middle frame, assuring the safe and smooth process.

Optical films that are thermo-formed to create a curved surface while maintaining a fixed magnitude and orientation of the local in-plane birefringence. While perhaps not practical to maintain the magnitude of the differences in index of refraction between three orthogonal axes in a material undergoing an arbitrary deformation, it is possible to maintain the difference between two of the indices under certain conditions. This enables the incorporation of functional retarder layers into curved structures such as lenses and reflective polarizer films. Furthermore, it enables the minimization of retardation induced in the surrounding initially isotropic substrates.

A protective packaging web is disclosed. The web includes a flexible inflatable web that includes inflatable chambers having inlets and configured for receiving a fluid from the inlets and sealing the fluid therein, the inflatable chambers being configured such that, when inflated, the inflatable web structure has a first contoured exterior surface including a plurality of peaks and valleys, and a flexible first outer ply affixed to the peaks and detached from the valleys of the first contoured surface, such that when the inflatable chambers are inflated, the first outer ply extends along a phantom first tangential surface, bridging the valleys of the first contoured surface, such that when the chambers are inflated the affixed first outer ply and the inflatable web cooperatively form a framed structure having significantly elevated bending stiffness compared to a bending stiffness resulting from the inflatable web structure absent the attached first outer ply.

A thermoforming mold device (1) providing a piece with a thin wall starting with a sheet of thermoplastic material is provided. At least one (3) of two parts of the mold (3, 3′) comprises at least one means (4) of local deformation of a sheet (2′) in the mold (3, 3′) in its closed state, the at least one means (4) comprises a piece of hollow molding with a peripheral edge, which can be connected selectively to a source of suction and can be displaced between a folded position, in which the molding piece is situated in close proximity with the wall of the thermoformed piece, and a deployed position, in which the molding piece is applied under pressure with its peripheral edge against the wall of the thermoformed piece upholding the other part of the mold.
