Abstract: The present disclosure describes a spreader roll (101) that can help spread webs laterally in a web processing operation, in particular to reduce or remove the presence of wrinkles or bagginess in the web. The spreader roll can be a reverse crown roll that is covered with a resilient material (160) to assist spreading the web to remove wrinkles. The surface curvature of the spreader roll (101) can be formed using layers of material such as a tape, to easily and readily approximate the shape of a reverse crown roll.

Abstract translation: 本公开描述了一种在卷筒纸加工操作中有助于横向扩展织带的扩展辊（101），特别是减少或消除卷筒纸中皱纹或袋状物的存在。 吊具卷可以是用弹性材料（160）覆盖的反向冠状辊，以帮助铺展网来去除褶皱。 扩展辊（101）的表面曲率可以使用诸如胶带的材料层形成，以容易且容易地接近反向冠辊的形状。
