A forage compactor is provided having a frame that has cross bars supporting risers that in turn support a shaft. At least one asymmetric wheel is supported by the shaft. The wheels can be paired whereby journals are used to connect to the shaft between recesses of respective wheels. Each wheel has a first side and a second side, each with radiused portions that turn forage away from the wheel. The wheels have a band that is flush with the outer portion of the wheel sides to prevent lifting of the forage. A storage assembly is provided and is integrated into the framework. The storage assembly can be stored within the frame when the compactor is in use, and can be deployed to a locked position in order to store the compactor. A hitch framework is provided that can attach to multiple categories of three point hitches.

A manufacturing apparatus of a flexible display device, including: a main chamber in which a display device is mounted; an auxiliary chamber configured to inject a first pressing material having fluidity into the main chamber; and a driving portion configured to rotate the main chamber.

A particulate sizer includes an infeed for receiving a plurality of particulates, a first roller, and a second roller. The first and second rollers break down the plurality of particulates as the plurality of particulates passes through a gap between the first and second rollers. The width of the gap varies along a length of the first and second rollers. Accordingly, the first and second rollers compress some particulates to a first size and compress other particulates to a second smaller size. In addition, each of the first and second rollers has a textured outer surface for carrying the plurality of particulates through the gap.

A roller for a roller press has a core formed with axially opposite outer ends, an axially central passage, and axially spaced and radially extending inlet and outlet passages extending radially at the outer ends from the central passage and opening radially outward at an outer surface of the core. A coolable jacket surrounds the core, and respective manifold rings are mounted on outer ends of the core, cover inlet and outlet passages at the end faces of the jacket. Respective L-shaped connecting passages each have an axially extending segment opening into a respective one of the cooling passages of the jacket and a radially extending segment opening into the respective groove.

There is provided a method for manufacturing a battery electrode. The method includes: forming a precursor of the battery electrode including a double-sided coating area in which both sides of a current collector are coated with an electrode material layer and a single-sided coating area adjacent to the double-sided coating area; subjecting the current collector located at a boundary portion between the double-sided coating area and the single-sided coating area to a heat treatment locally; and pressurizing the precursor of the battery electrode. The single-sided coating area includes a main side of the current collector that is coated with the electrode material layer.

A simulation method and a simulation apparatus of roll press for secondary battery production are provided. The simulation apparatus comprises a memory configured to store at least one instruction; and at least one processor configured to execute the at least one instruction stored in the memory, the at least one instruction comprising instructions for executing a device operation unit comprising a 3D roll press associated with secondary battery production, a facility operation unit comprising a plurality of adjustment parameters for determining the operation of the 3D roll press, a main operation panel comprising a plurality of buttons for driving a 3D roll press, and a quality confirmation unit comprising quality information related to the quality of a material produced by the 3D roll press; obtaining at least one of first user behavior information obtained through the device operation unit, button manipulation information obtained through the main operation panel, or first user condition information obtained through the facility operation unit; determining an operation of the 3D roll press based on at least one of the obtained first user behavior information, the obtained button manipulation information, or the obtained first user condition information; and executing the operation of 3D roll press based on the determined operation.

A cantilevered screw assembly comprising a speed reducer to facilitate rotation of a screw. The speed reducer may be connected to a torque arm that is adapted to control or limit undesired movement (e.g., wobbling, orbital movement, etc.) of the screw during operation. In effect, one exemplary embodiment of a speed reducer may essentially float on a pivoting torque arm (and the shaft of the screw) such that the torque arm is adapted to limit undesired movement of the speed reducer and screw. As a result, an exemplary embodiment may eliminate the need for alternative drive systems or other means to control undesired movement of the screw. An exemplary embodiment may be particularly useful for light or infrequent duty or other small-scale applications to reduce the likelihood of a breakage of a screw or another portion of a cantilevered screw assembly (e.g., the bearing(s) or bearing assembly, the gears, etc.).
