    • Apparatus and methods are provided for the embossing of a sheet of flexible graphite material between a pair of embossing rollers. The embossing rollers include a primary embossing roller (12) and a backup roller (14). The primary embossing roller has an embossing pattern (24) defined thereon. One or both of the rollers include a raised stabilization area adjacent a periphery of the embossing pattern. The raised stabilization area preferably has a roughened outer surface for better gripping the sheet of flexible graphite material. The raised stabilization areas (34), (36), (38), and (40) apply a stabilizing force to the sheet adjacent the periphery of the embossing pattern, thereby limiting egress of the material laterally away from the embossing pattern. The roughened surfaces increase the grip of the raised areas upon the sheet, thus aiding in pulling the sheet between the rollers and also aiding in the application of lateral stabilization forces to the sheet.
    • 提供了设备和方法,用于在一对压花辊之间压花一片柔性石墨材料。 压花辊包括主压花辊(12)和支承辊(14)。 主压花辊具有限定在其上的压花图案(24)。 一个或两个辊包括邻近压纹图案的周边的凸起的稳定区域。 升高的稳定区域优选具有粗糙的外表面,以更好地夹持柔性石墨材料片。 凸起的稳定区域(34),(36),(38)和(40)对邻近压花图案的周边的片施加稳定力,从而限制材料横向离开压花图案的出口。 粗糙表面增加了片材上的凸起区域的抓握力,从而有助于将片材拉动在辊子之间,并且还有助于向片材施加横向稳定力。
