    • A color printing arrangement has a series of printing stations in each of which a different color is imprinted upon predetermined regions of a travelling band to form color images. A device for measuring the width of the band by sensing the edges thereof is located immediately upstream of each printing station. The width of the band at the first printing station is compared with the width at each of the following printing stations. As long as the widths at the latter printing stations are the same as that at the first printing station, the band is allowed to continue travelling unchanged. However, when the width of the band at a printing station downstream of the first printing station differs from the width at the first printing station, the band is operated upon to return the width to its original value. The reason is that a departure from the original width of the band causes the predetermined regions which are to be imprinted to be moved out of alignment with the printing devices in the printing stations. By returning the width to its original value, the alignment of the predetermined regions is restored.
    • 彩色印刷装置具有一系列印刷站,每个印刷站中不同的颜色印在行进带的预定区域上以形成彩色图像。 用于通过感测其边缘来测量带的宽度的装置位于每个印刷台的紧邻的上游。 将第一印刷台处的带的宽度与下列各印刷台的宽度进行比较。 只要后一个印刷站的宽度与第一印刷台的宽度相同,则允许该带继续行进不变。 然而,当在第一印刷台下游的印刷站处的带的宽度与第一印刷台的宽度不同时,该带被操作以将宽度返回到其初始值。 原因在于,与频带的原始宽度的偏离导致要被打印的预定区域移动离开与打印站中的打印装置对准。 通过将宽度返回到其原始值,恢复预定区域的对准。

    • A cover layer, for example applied to a carrier sleeve (3), is volume compressible by being formed as a unitary seamless cover layer (3) of foamed or expanded or blown material resulting in micropores or microcells of less than 0.01 mm, with a percentage of closed or individual cells to total cells being greater than 50%. This cover layer will have a bounce-back or rebound elasticity of greater than 95% and preferably has a thickness of between about 1 to 5 mm. It may be covered with a polyurethane or rubber based outer cover layer of, for example, about less than 0.5 mm thickness. The cover layer is applied by providing a base substance which is made thixotropic, stirring it and applying it in liquid form as a spiral stripe on a rotating and axially moving cylinder (5), the material being free foaming and curing as it is being applied, and when still in spreadable and somewhat flowable condition to form a uniform seamless cover layer which includes individual, unconnected micropores or microcells. Additives such as talcum, and suitable selection of curing agents or activators and inhibitors, as well as blowing agents can control the size and eventual density of the material.
    • 例如应用于载体套管(3)的覆盖层通过形成为发泡或膨胀或吹塑材料的整体无缝覆盖层(3)而体积可压缩,从而产生小于0.01mm的微孔或微孔,其中 封闭或单个细胞对总细胞的百分比大于50%。 该覆盖层将具有大于95%的反弹或回弹弹性,并且优选地具有约1至5mm之间的厚度。 它可以覆盖有例如大约小于0.5mm厚度的聚氨酯或橡胶基外层。 通过提供一种制成触变性的基础物质,将其搅拌并以旋转和轴向移动的圆柱体(5)上的螺旋状条形式将其作为螺旋状条应用于其上来施加覆盖层,该材料在被施加时是自由发泡和固化的 ,并且当仍然处于可展开和稍微可流动的状态以形成均匀的无缝覆盖层时,其包括单独的,未连接的微孔或微孔。 添加剂如滑石和合适的选择固化剂或活化剂和抑制剂以及发泡剂可以控制材料的尺寸和最终的密度。
