    Abstract: A machine for interfolding webs of material which includes a plurality of interfolding mechanisms for interfolding webs into a plurality of elongate bundles. Drive mechanism is provided for advancing first and second ones of the bundles in taut condition, with the second bundle being disposed beneath the first bundle. First and second fold plates are disposed vertically intermediate the first and second bundles. These plates are inclined relative to a vertical plane and lie in generally mutually parallel planes. The first fold plate is arranged to guide the top web of the first bundle in an upwardly unfolded condition during advancement of the first bundle. The second fold plate is arranged to guide the bottom web of the second bundle in a downwardly unfolded condition during advancement of the second bundle. The first and second fold plates terminate prior to the point where the second bundle is deposited onto the first bundle, thereby allowing the tautly maintained, unfolded webs to assume an interfolded posture. The interfolding mechanisms each include a folding assembly which includes a stub element in the shape of a segmented curve. A rotatable roll is disposed intermediate a discharge edge of the stub element and a folding plate. A web slides over the stub element and is discharged from the discharge edge in a non-tangential direction onto the guide roller. The stub element is pivotably displaceable away from the guide roller to facilitate access to the mechanism.

    Abstract translation: 一种用于折叠材料网的机器，其包括用于将幅材折叠成多个细长束的多个折叠机构。 提供驱动机构用于在绷紧状态下推进第一和第二束，其中第二束设置在第一束下方。 第一和第二折叠板垂直地设置在第一和第二束之间。 这些板相对于垂直平面倾斜并且位于大致相互平行的平面中。 第一折叠板布置成在第一束的推进期间向上展开的状态引导第一束的顶部腹板。 第二折叠板布置成在第二束的推进期间向下展开的状态引导第二束的底部腹板。 第一和第二折叠板在第二束被沉积到第一束之前终止，从而允许紧张地保持的，未折叠的纤维网呈现折叠的姿势。 折叠机构各自包括折叠组件，其包括呈分段曲线形状的短截线元件。 可旋转辊设置在短截线元件的排出边缘和折叠板之间。 纤维网在短截线元件上滑动，并且以非切向方向从排出边缘排出到引导辊上。 该短截线元件可枢转地移动远离该导辊以便于接近机构。
