    • A method of coating a peripheral surface of a sleeve core with a radiation curable coating liquid including the steps of: supporting a sleeve core in a vertical position coaxial with a coating axis; providing an annular coating collar, supplying the coating liquid to the annular coating collar and moving the annular coating collar along the sleeve core in a vertical direction coaxial with the coating axis, thereby coating a layer of the coating liquid onto the peripheral surface of the sleeve core; wherein the coated layer of the coating liquid is cooled by the peripheral surface of the sleeve core to have a viscosity at the temperature of the peripheral surface of the sleeve core and at a shear rate of 10 s−1 which is larger than a minimum viscosity ηmin, with: η min = d 2 50 wherein d represents the thickness of the coated layer expressed in μm, and ηmin is expressed in mPa·s. Also, a coating device for performing the above coating method.
    • 一种用可辐射固化涂布液涂覆套筒芯的外围表面的方法,包括以下步骤:将套筒芯支撑在与涂覆轴线同轴的垂直位置; 提供环形涂层套环,将涂覆液体供应到环形涂层套环,并沿着与涂覆轴线同轴的垂直方向沿套筒芯移动环形涂层套环,从而将涂层液层涂覆到套筒的外周表面上 核心; 其中涂覆液体的涂层被套筒芯的外周表面冷却,以在套筒芯的外周表面的温度下以10s -1的剪切速率粘度大于最小粘度 &eegr; min,with:&eegr; min = d 2 50其中d表示以μm表示的涂层的厚度,&eegr min以mPa·s表示。 另外,用于进行上述涂布方法的涂布装置。
