The present invention relates to a method for making an anvil roll, the method comprising the steps of: providing a cylindrically-shaped body consisting of a first material, wherein the first material is selected from the group consisting of: an iron alloy, an aluminum alloy, and a titanium alloy, and wherein the body comprises an outer circumferential surface; adding one or more metallic materials in the form of powder; and fusing, by applying power from a laser source, the one or more metallic materials to the outer circumferential surface of the body to form a plurality of protrusions having a conical or frustro-conical shape comprising tapering sides, from a broader base at the outer circumferential surface tapering outwardly towards a narrower tip or having a cylindrical shape.

A drive member for driving a sheet of workpiece through a die machine including a backing layer including a first surface defined in a first dimension by a first width and defined in a second dimension by a first length and a padding layer comprising a first surface defined in the first dimension by a second width and defined in the second dimension by a second length, where the padding layer is composed of a compressible foam material. In an uncompressed state of the padding layer, the second length of the padding layer is longer than the first length of the backing layer, and in a compressed state of the padding layer, the padding layer is compressed along the second dimension to match the first length of the backing layer, and the first surface of the padding layer is bonded to the first surface of the backing layer.

This application relates to an amplifier selectively operable in first or second modes. The first mode is a BTL mode with first and second output drivers (103p, 103n) both active to generate respective driving signals that vary with an input signal. The second mode is an SE mode, where the first output driver (103p) is active to generate a driving signal at and the output of the second driver (103n) is held constant. A controller (201) selectively controls the mode based on an indication of output signal amplitude. In the first mode, a ratio of magnitude of the two driving signals varies with the indication of output signal amplitude, i.e. the magnitudes of the two driving signals may vary so as to be not equal.

A cutting device for cutting a continuous body of an electrode plate, the electrode plate including a current collector plate, a first active material layer, and a second active material layer, the cutting device including: a first process unit that causes a first cutting blade to form an incision in the first active material layer; and a second process unit that causes a second cutting blade to cut the continuous body.
