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 pressing roll device, in which a unit cell passes between an upper roll and a lower roll, includes: the lower roll; the upper roll; a lower mount on which the lower roll is mounted and which is fixed in movement; an upper mount on which the upper roll is mounted and which is restricted by a bracket so as to ascend and descend by the bracket; and a stopper disposed between the lower mount and the upper mount so that the lower roll and the upper roll are spaced apart from each other.

Systems, methods, and apparatus for conditioning bamboo or other types of vegetable cane are provided. In one aspect, the present technology provides a cane processing assembly for use with a substantially flattened sheet of bamboo culm or vegetable cane having a plurality of longitudinally oriented fiber bundles. The assembly comprises first and second conditioning rollers configured to apply pressure to the sheet that breaks at least some natural bonds connecting laterally adjacent fiber bundles in the sheet. The first and second conditioning rollers are adjustable relative to each other so as to vary the pressure applied to the sheet by the first and second conditioning rollers.

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.

A grinding roll including a roll body having a cylindrical outer surface extending axially between a first end and a second end and a flange attached to at least one of the first and second ends. The flange includes an outer edge that extends radially past the cylindrical outer surface of the roll body. A first surface of the flange forms a perpendicular continuing surface with the cylindrical outer surface of the roll body. A second surface of the flange forms a continuation of one of the first and second ends of the roll body. The flange includes wear protection liner elements on the first surface. The first surface of the flange includes at least one lower part adjacent the cylindrical outer surface of the roll body and at least one upper part adjacent the outer edge of the flange. The lower part includes a first type of wear protection liner elements and the upper part includes a second type of wear protection liner elements. The average covering area of the second type of wear protection liner elements is larger than that of the first type of wear protection liner elements.

The disclosure relates to a roller crusher that includes a frame, first and second crusher rolls arranged axially in parallel with each other and a deflection distributor. The roller crusher further includes at least one load sensor configured to detect a material load in the deflection distributor and at least one positioning sensor configured to detect a parameter pertaining to a distance between a first point and a second point of the roller crusher. At least the first point is defined on the deflection distributor or on one of movable bearing housings of the roller crusher. The disclosure further relates to a method for monitoring the physical condition of the deflection distributor and to a refitting kit for a roller crusher.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

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.
