Abstract: A method of manufacturing a suction roll shell for use in a paper-making machine utilizes a mandrel with a length and a cross-sectional area corresponding to the shell. The mandrel has a plurality of generally radially extending holes. A plurality of pins are placed in the holes, with each pin extending radially outward from the shell a distance greater than a desired thickness of the shell. At least one elongate fiber is wound around the mandrel to form the shell with the desired thickness. The pins are removed from the mandrel and the shell.

Abstract: This invention is directed to a paper-making machine utilizing rotating cylinders, especially dryer cylinders, with a drying felt intertwined about the dryer cylinders to compress the wet paper against the dryer cylinders as the wet paper travels therealong. A threading doctor assembly with a blowpipe air nozzle blowing system is associated with each dryer cylinder. When air is flowing into the blowpipe blowing system, the leading tail of the wet paper is directed from the preceding dryer cylinder to the next. A proximity sensor associated with each threading doctor assembly is in communication with a controller and is positioned to determine if the wet paper is within a detection area. Air valves or solenoids coupled between an air supply system and the blowpipes are also coupled to the controller. As the leading tail of the paper is detected by a proximity sensor to be within the detection area, the next several solenoids associated with the next several threading doctors in the paper advance direction are activated. As well, solenoids associated with the blowpipes of the threading doctors that are more than two or three behind the proximity sensor, relative to the paper advance direction are deactivated. Such sequencing of blowpipes as the leading tail advances through the system reduces the air supply pressure necessary for the system.

Abstract translation: 本发明涉及一种利用旋转圆筒，特别是干燥器滚筒的造纸机，其中干燥机缠绕在干燥机圆筒上，以随着湿纸沿着湿纸张沿湿纸张压缩湿纸。 具有吹气管喷嘴吹风系统的穿线医生组件与每个干燥筒相关联。 当空气流入吹管系统时，湿纸的前尾从前一个干燥滚筒向下引导。 与每个穿线刮刀组件相关联的接近传感器与控制器通信并被定位以确定湿纸是否在检测区域内。 联接在供气系统和吹管之间的空气阀或螺线管也耦合到控制器。 由于接近传感器检测到纸张的尾部尾部处于检测区域内，所以与纸张前进方向上的接下来的几个螺纹医生相关联的下一个螺线管被激活。 同样，相对于纸张提前方向，与接近传感器相距大于二或三个的螺纹医生的吹管相关联的螺线管被去激活。 作为领先尾巴的排气管系统的排序可以减少系统所需的供气压力。

Abstract: The invention is directed to a paper machine including a headbox having an inlet and an outlet. A fluid conduit is connected to the inlet of the headbox. A sensor is disposed in communication with an interior of the headbox. The sensor senses a pressure of the fiber suspension within the headbox and provides a signal corresponding thereto. A first pump is connected to the fluid conduit and supplies a fiber suspension to the headbox through the fluid conduit. A second pump is connected to the fluid conduit between the first pump and the headbox, and further is connected to the sensor. The second pump is a substantially pulseless pump, and transports the fiber suspension away from the fluid conduit, dependent upon the sensed signal.

Abstract: A cross beam in a papermaking machine frame, having a specific overall length is composed of three nested beam elements, namely an outer beam element, a middle beam element and an inner beam element. The middle beam element is at its one end rigidly connected with the outer beam element and on its other end with the inner beam element. The material of the middle beam element, for instance aluminum, has approximately twice the coefficient of thermal expansion as compared to the material of the other beam elements, for instance steel. Therefore, the overall length of the beam remains essentially unchanged if a temperature change entails a length change of the beam elements.
