摘要： A paper sample press has a drawer slidably mounted on a base. A plurality of generally vertical guide posts are mounted on the base on opposed sides of the drawer. The drawer has a lower platen mounted thereon for supporting a stack of paper samples. The drawer is slidable on the base from a retracted position between the guide posts to an extended position wherein the lower platen is extended out from between the guide posts, and returnably slidable on the base from the extended position to the retracted position. A vertically selectively actuable press cover is vertically mounted on a piston above the lower platen when the drawer is in the retracted position. The piston is selectively actuable so as to selectively lower and elevate the press cover between a raised position and a lowered paper sample engaging position. The paper sample press has piston support and a selective actuation device for supporting and selectively actuating the piston vertically over the lower platen so as to vertically selectively translate the press cover along a vertical press axis aligned with the lower platen between the raised position and the lowered paper sample engaging position. The piston support and selective actuation means is mounted on the guide posts. A constant compression device is provided for applying a generally constant compression pressure along the vertical press axis to a stack of paper samples placed on the lower platen when the drawer is in the retracted position and the press cover is in the lowered paper sample engaging position.
摘要翻译：纸样品压机具有可滑动地安装在基座上的抽屉。多个大致垂直的引导柱安装在底座上与抽屉相对的两侧。抽屉具有安装在其上的下压板，用于支撑一堆纸样品。抽屉可以在底座上从引导柱之间的缩回位置滑动到延伸位置，其中下压板从引导柱之间延伸出来，并且可从该伸出位置到缩回位置在基座上可自由滑动。当抽屉处于缩回位置时，垂直选择性致动的压盖垂直地安装在下压板上方的活塞上。活塞可选择性地致动，以便在升高位置和降低的纸样品接合位置之间选择性地降低和提升压盖。纸张样品压机具有活塞支撑件和选择性致动装置，用于在下压板上垂直地支撑和选择性地致动活塞，以便沿着与下压板对准的垂直压力轴垂直地选择性地平移压盖在升高位置和下降位置之间纸样接合位置。活塞支撑件和选择性致动装置安装在导向柱上。提供恒定的压缩装置，用于当抽屉处于缩回位置并且压盖处于降低的纸样品接合位置时，沿着垂直按压轴线施加大体上恒定的压缩压力，将堆叠的纸样放置在下压板上。
