摘要： A method for exposing a sheet to light radiation while it is under pressure, in which successive portions of the sheet which slightly overlap one another are sequentially clamped between a pressure plate and a light transmitting plate, and are irradiated with electromagnetic radiation through the light transmitting plate in the clamped condition. Further, a device for practicing the method is disclosed, which includes: a light source; a light transmitting plate arranged with the light source on one of its sides; a pressure plate which opposes the other side of the light transmitting plate; a member for relatively biasing the light transmitting plate or the pressure plate towards and away from each other; a device for transporting the sheet passing between the light transmitting plate and the pressure plate; and a control for controlling the light source, the biasing member, and the transporting device, which causes the light source to emit light when the pressure plate and the light transmitting plate are pressed against each other with the sheet between them, and which causes the transporting device to transport the sheet through a distance less than the width of the light transmitting plate, when the light transmitting plate and the pressure plate are separated by more than a certain predetermined distance.
摘要翻译：一种用于在片材受压的同时将片材暴露于光辐射的方法，其中彼此稍微重叠的片材的连续部分被顺序地夹在压力板和透光板之间，并且通过透光板照射电磁辐射板在夹紧状态。此外，公开了一种用于实施该方法的装置，其包括：光源; 光源在其一侧上布置的透光板; 与透光板的另一侧相对的压板; 用于相对地使透光板或压板相对偏压的构件; 用于传送在透光板和压力板之间通过的片材的装置; 以及用于控制光源，偏置构件和输送装置的控制装置，当压板和透光板在它们之间彼此压靠时使光源发光，并且这导致传送装置，以便当透光板和压板分开多于一定的预定距离时，将片材输送的距离小于透光板的宽度。
