摘要： A winder has a scraper mounted about the axis of a winder drum for circumferential movement. The scraper has a semi-cylindrical concave surface which extends in the cross machine direction, the concave surface meets a second surface to form a scraping edge. The scraping edge engages the winder drum, scraping a web from the surface of the winder drum and pressing the web into engagement with double-sided sticky tape on a winder core with the concave surface. An alternative embodiment scraper has a flexible blade which extends in the cross machine direction and which functions similar to a spatula to scrape the pulp web off the surface of the winder drum and wipe the pulp web onto the double-sided sticky tape on the winding core.

摘要： A tissue paper crimper of greater rigidity is provided by mounting crimper disks to linear bearings which in turn are mounted to a carriage which can be positioned in the cross machine direction on a frame. The crimper disks are pressed against anvil roll pneumatic actuators. The use of linear bearings allows the crimper to run at higher operating speeds. An air knife is positioned so that a jet of air following a Coanda surface periodically blows against the rotating crimping wheel and thereby removes fibers before they build up. Buildup of fibers on the crimping wheels from the tissue webs being crimped can cause the wheels to become unbalanced, resulting in undesirable vibration. The rigid mounting and the prevention of fiber buildup will allow the crimper of this invention to operate at higher machine speeds.

摘要翻译： 通过将卷边盘安装到直线轴承上，提供了更大刚度的薄纸卷纸机，该直线轴承又安装在可在框架上沿横向方向定位的托架上。 卷边盘被压靠在砧辊气动执行机构上。 使用直线轴承允许卷曲机在更高的运行速度下运行。 空气刀被定位成使得随着柯恩达表面的空气射流周期性地吹动旋转的压接轮，从而在构成之前除去纤维。 由卷边的卷筒纸卷绕在卷边轮上的纤维可能导致车轮不平衡，导致不期望的振动。 刚性安装和防止纤维堆积将允许本发明的卷曲机以更高的机器速度运行。
