发明名称 Contoured batt produced by a scarfing method using a contouring roll
摘要 A scarfing method and apparatus are disclosed for making a longitudinally and transversely contoured batt on a moving fibrous web. The apparatus comprises a scarfing roll disposed on one side of a foraminous belt and a contouring roll, having a nonuinform surface, disposed on the opposite side of the belt. As the contouring roll is rotated, it raises the belt and the fibrous web towards the scarfing roll, according to the shape of the nonuniform surface. Hence, a contour is provided in the direction of movement of the web. The transverse contour can be provided by the shape of the scarfing roll itself.
