摘要： The present invention presents a way to manufacture in particular high quality cutting edges of a wiping lip that are usually used in wiper blades to wipe windscreens of a car. Herein two converging knives (110,120) are used together to cut the elastomer or rubber edge (180,190) from two different sides which are opposing each other and thus during the cutting operation provide a low irregularity which is below 1 µm. High quality is achieved by lowering the temperature of the elastomer or rubber during the cutting operation.
In order to avoid a knife penetrating and breaking through the elastomer or rubber edge the knives are coupled and movable with respect to the elastomer or rubber edge in a transversal direction thereof such that a similar distributed and balanced force is exerted by the two knives on the respective side of the elastomer or rubber edge. Oscillating movements that may occur during fast cutting speeds are dampened by damping means in form of hydraulic or elastomeric of friction means.
Also a method for measuring and determining the quality of the finished elastomer or rubber edge (180,190) during a manufacturing process is provided wherein the wiping lip is pressed against a surface (525) with a certain force (555) and at the same time hot or cold gas is blown against the edge and using thermographic imaging means to determine the gas distribution that penetrates between the edge and the surface as a measure of quality.

摘要翻译： 本发明提供了一种制造擦拭唇缘的特别高品质的切削刃的方法，通常用于擦拭器刮片以擦拭汽车的挡风玻璃。 这里，两个会聚刀（110,120）一起使用以从彼此相对的两个不同侧切割弹性体或橡胶边缘（180,190），因此在切割操作期间提供低于1μm的低不规则性。 通过在切割操作期间降低弹性体或橡胶的温度来实现高质量。 为了避免刀穿透并穿过弹性体或橡胶边缘，刀在其横向方向上相对于弹性体或橡胶边缘联接并且可移动，使得两个刀在其上施加相似的分布和平衡的力 弹性体或橡胶边缘的相应侧面。 在快速切割速度期间可能发生的振荡运动由阻尼装置以摩擦装置的液压或弹性体的形式而衰减。 还提供了一种用于在制造过程中测量和确定成品弹性体或橡胶边缘（180,190）的质量的方法，其中擦拭唇缘以一定的力（555）压在表面（525）上，并且同时热 或者将冷气体吹向边缘并且使用热成像装置来确定穿透边缘和表面之间的气体分布作为质量的量度。
