A thickness meter detects a thickness of an electrode plate of a secondary battery at three or more points in a width direction of the electrode plate. A calculator calculates three feature amounts of a first deviation between the thickness target value and a thickness measurement value of a point closest to a first compression mechanism among the three or more points, a second deviation between the thickness target value and a thickness measurement value of a point closest to a second compression mechanism among the three or more points, and a secondary component of a thickness profile of the electrode plate from thickness measurement values at the three or more points and the thickness target value, and adaptively changes the setting values of the first compression mechanism, the second compression mechanism, a first bend mechanism, and a second bend mechanism on the basis of the three feature amounts.

A radial press is provided including a base, a hollow ring die mounted on the base rotatably relative to a press axis with an inner contour tapering in the direction of the axis and rotationally symmetrical, and a rolling element unit rotatable relative to the axis and having a pressure ring, which surrounds the axis, and a plurality of rolling elements arranged around the axis which are rotationally symmetrical. The rolling elements are supported on the pressure ring at a variable distance from the axis and can roll on the inner contour of the ring die. A rotary drive acts on the ring die or the rolling element unit and effects rotation about the axis. A feed drive also acts on the rolling element unit or the ring die and effects axial displacement of the rolling element unit and the ring die relative to each other.

A manufacturing apparatus for an electrode plate includes: a conveyance line of the electrode plate having an applied portion in which an electrode active material is applied to a surface of a base material and a non-applied portion in which the electrode active material is not applied to the surface of the base material; a compression roll provided in the conveyance line and compressing the applied portion; and a tension reducing mechanism provided in at least one of an upstream section ending at the compression roll or a downstream section starting at the compression roll in the conveyance line and reducing a tension applied to the electrode plate.

The present disclosure encompasses a composition comprising three-dimensional shapes, wherein each shape consists essentially of choline chloride, and methods of making such three-dimensional shapes.

According to an exemplary embodiment of the present invention, a roll press apparatus is provided. The roll press apparatus presses electrode sheets, each including a both-side coated portion where an electrode mixture is applied to both sides of a current collector and a one-side coated portion where the electrode mixture is applied to one side of a current collector, by passing the electrode sheet through a separated space between a pair of press rolls.

The invention relates to a method for mounting segments on and dismounting segments from a roller shaft. These segments are braced on the roller shaft via at least one bracing element in a receptacle provided for this purpose and are thus frictionally and form-fittingly connected in their position.

An edge of a pressing target is suppressed from cracking. A roll press apparatus 100 has a roller 30 that presses a pressing target M. The roller 30 includes a first roller part 31 that presses the pressing target M in a radial direction of the roller 30 and a second roller part 32 that protrudes further than the first roller part 31 in the radial direction on each side of the first roller part 31 in an axial direction of the roller 30 to make contact with the pressing target M in the axial direction. Each of the second roller parts 32 has an elastic member E2 at least in a portion in contact with the pressing target M.
