A disclosed sizing roller apparatus for a folding process of a battery cell includes: a table fixing and supporting a battery cell; a base plate disposed on a side of the table; a plurality of sizing rollers disposed on the base plate and each having a rotation axis, which is inclined inward toward a folding portion of the battery cell, to press the folding portion of the battery cell in contact with the folding portion; and a plurality of air spray nozzles disposed on the base plate and spraying air to the plurality of sizing rollers.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

The invention regards a process for manufacturing a bicycle saddle, which provides a central through channel as well as a hull with a through hole (4′); a polyurethane layer and a liner.

By means of this process it is possible to make sure that, unlike the saddles of the state of the art, said central through channel is completely devoid of the edge present around the aforementioned, with significant advantages from both an aesthetic and functional point of view for the user.

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.

A method for creating a flexible portion or bending portion within a rigid structure. The method can also be used for creating a flexible structure from a rigid material. The method includes providing a substantially rigid material, such as, but not limited to, metals, alloys, hard plastics, and the like, and selectively removing portions of the rigid material defining a geometric pattern in the rigid material. A bending radius of the flexible portion is defined by the geometric pattern. The rigid structure may be used to create an enclosure, a cover for an electronic device, one or more hinges, or the like.

A luggage case includes a case woven by thermoplastic composite material, the case includes four integrally connected lateral walls, a bottom connected to the lateral walls, and four arc-shaped corners at cross points of the lateral walls, between each of the arc-shaped corners and the bottom is defined a hole. Any two of the lateral walls which are neighboring to each other are provided with a first overlapping portion and a second overlapping portion, respectively, and the first and second overlapping portions are integrally connected to each other without a notch formed therebetween, each of the corners of the case is folded to make the first and second overlapping portions overlapped with each other, so as to form a thickened pieces on an inner surface of each of the lateral walls.

A method includes the step placing composite laminate material onto a three dimensional forming tool with an external surface and at least four junctures associated with the external surface. Each juncture is positioned between two adjacent planar surfaces in which each of the two adjacent surfaces extend in a different plane, the junctures converge and each juncture defines a line of direction. The three dimensional forming tool arranged in a two dimensional pattern, has the lines of direction and the two adjacent planar surfaces positioned on opposing sides of each of the at least four junctures are all positioned in a common plane. The line of direction of each of the at least four junctures in the two dimensional pattern converge to a common point. At least one line of direction is not in alignment beyond the common point with another line of direction. Tool apparatus is also provided.

A three-dimensional engineered shaped fiber configuration is formed using determined structural requirements for a three-dimensional engineered shaped fiber configuration and ascertained properties of an engineered molded fiber fiberboard material. A first cut on a top surface and a second cut on a bottom surface of the fiberboard material are calculated. These calculations are based, at least in part, on the structural requirements properties of the fiberboard material. The first cut and the second cut each have a depth, a width, and a position. The first cut and the second cut have a spacing between them such that the flat piece of fiberboard material can be folded at a point located in the spacing between the first cut and second cut to position a first portion of the fiberboard material at a particular angle with respect to a second portion of the fiberboard material.

A hood for a roll up shutter is provided wherein the hood configured to be transported in a flat or rolled up configuration and assembled upon delivery. The hood includes a sheet having a first surface and a second surface and at least one indentation formed on at least one of the first surface or the second surface, the indentation configured to facilitate bending at the at least one indentation wherein after delivery, the sheet is bent at the at least one indentation so as to form the hood.

A fold-enhancing device includes a pressing member, at least one retaining member, and a moving mechanism. The pressing member presses against a fold line of a recording-medium bundle folded into a booklet shape. The recording-medium bundle is obtained by stacking multiple sheets of recording media. The retaining member retains the recording-medium bundle and is provided at a position located away from the fold line in a direction intersecting the fold line and not in contact with the pressing member. The moving mechanism moves the pressing member and the retaining member in a direction extending along the fold line.
