Description
Изобретение относитс к электрографии. Оно может примен тьс в электрографических машинах. И.чвестрсо устройство, содержащее нагренате .чьный ролик с теплонроьод шей поверхностью и второй ролик цилиидрическон формы I . Устройство работает следующим образо.м. Листовой или рулонный материал с норошковым изображением проходит мржду плавильным роликом и нрижатим к нему нилиндрическнм гюддержинаюшим роликом. Плавильный ролик имеет электрический Е1агревательи1,1й элемент , расположенный внутри него вдоль оси, который поддерживает температуру ролика.По рошконый про витель раснлавл стс и закреплиетс на листовом или рулонном материале. Недостатком ука.чанного устройства вл етс то, что при .Закреплении норошкового изображени но вл ютс складки на листо1.1г)м или рулоннг м материале, из-зл взаимо.чействи нагретого r(uif3K,,rfiMoro ролика и подлерживаюнцго раликз. ..Это приводит к тому, что часть гюлучеми о изображени может бьць уннчтожеиа . Цель изобретени - нов1 ине11ие качесша оттиска нуте.м уме11ьн ени всмможиоп-и ггп короблени . Это достигаетс тем, что нагргв;гкмьи1-.1Й ролик имеет вогнутую боковую ноигр ность. причем диаметр его сужаетс от концов внутрь. Пре.аночтительно, чтобы наим(мп.нгий дна метр ролика находилс в середине пп .ч.шиы.

It can be used in electrographic machines. I. queenso device containing a high-pressure roller with a heat-conducting surface and a second roller of a cylindrical-conic form I. The device works as follows. Sheet or roll material with a burrow image passes around the melting roller and applies a non-curved guiding roller to it. The melting roller has an electric heater that is located along the axis within the axis, which maintains the temperature of the roller. The electric cable has been melted and fixed on the sheet or roll material. The disadvantage of this device is that when fixing the burst image, but there are folds on the sheet 1.1 g) or roll material, due to the interaction of the heated r (uif3K ,, rfiMoro roller and supporting Judefaction ... This leads to the fact that part of the image of the image can be unscored. The purpose of the invention is a new quality print that is able to resist, and it can be achieved by the fact that the load has a concave side pattern. moreover, its diameter is narrowed from the ends inwards. To the smallest (m.pngy bottom meter of the roller was in the middle of pp. ch. wide. Two tapering parts may have the shape of a truncated cone and, pi may have npo; i (,: ib section cross-sectional, f1111) | shapes. In Fig. 1 the side view; on the fit. 2 - the same, the second version of it; On both figures, for clarity, the taper is much exaggerated. It was established that for longer roles up to 610 mm, The eyelet is almost eliminated if the diameg in the cpcuicii part is 0.15-0-0.20 mm menne at the ends.
