摘要： Provided are methods and apparatus for transporting either an entire web or discrete components of disposable products. The invention is a means of conveying the web or diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this. Methods and apparatus are disclosed to provide sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

摘要： A vacuum roller assembly adapted to singulate a sheet from a stack of sheets. The vacuum roller assembly comprising a stationary inner plenum having a substantially linear plenum slot disposed in fluid communication with the vacuum source and a rotating vacuum roller disposed over the stationary inner plenum and rotating about a rotational axis. The vacuum roller includes a plurality of apertures disposed in fluid communication with the substantially linear plenum slot and about the periphery in at least one region of the roller. Furthermore, each of the apertures is substantially slot-shaped and defines a major axis. The major axis is off-axis with respect to the substantially liner plenum slot of the inner plenum to reduce audible noise levels produced by the rotating vacuum roller as air flows through each rotating aperture into the stationary linear plenum slot.

摘要： This invention proposes a new, improved method and apparatus for applying web segments to a traveling web. Ears, or wings, are placed on a running web of disposable diapers. Because these webs are often asymmetrical or otherwise incompatible with the principle of slipping over the surface of a moving vacuum roll, the webs may float from side to side or otherwise be drawn out of square by asymmetrical forces. A vacuum groove is provided on a vacuum roll to counter these effects. Alternatively, a ridge with vacuum about the ridge is provided, also to pull a machine direction line of material into the groove or over the ridge, thereby giving the web some degree of cross-directional stability.

摘要： A vacuum timing device for applying a vacuum on a roll includes a roll with an axis of rotation, a surface, and a surface longitudinal axis oriented in a direction substantially parallel to the axis of rotation. The device also includes at least one vacuum line running along at least a portion of the length of the roll. The device also includes a plurality of apertures defined in a surface of the roll and in fluid communication with the vacuum line. In order to alleviate angular delay of vacuum propagation, the plurality of apertures is arranged in a line that is skewed with respect to the surface longitudinal axis. Preferably, the plurality of apertures is arranged in a line that is skewed away from the direction of rotation of the roll, thereby substantially eliminating the angular propagation delay as the vacuum roll operates.

摘要： A vacuum drum assembly for a printing machine has a drum with an array of passageways distributed along its length and around its periphery to permit airflow from outside the drum to inside the drum in response to reduced air pressure inside the drum. An array of valves are movable between a closed position in which that valve restricts at least one of the passageways and an open position in which the restriction of the same passageways is reduced. When a partial area of the drum is wrapped with a sheet of material, at least some of the passageway valves adjacent the edges of that area are open, and the valves for the passageways not covered by the sheet and not adjacent the edges of that area are closed. The drum open area is regulated to be small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the paper shape and size and the paper position on the drum, while minimizing the required suction flow. A duplex printing machine has two such vacuum drum assemblies with their drums parallel. The air pressure inside the drums is reduced and the drums are counter-rotated. Printing material is fed to the first drum and held on the first drum by vacuum and rotated therewith. A first print head prints on one side of the material. The material is released from the first drum in a direction towards the second drum and held on the second drum by vacuum and rotated therewith. A second print head then prints on the material on the second drum. The material is then released from the second drum.

摘要翻译： 用于印刷机的真空鼓组件具有滚筒，该滚筒具有沿其长度并围绕其周边分布的通道阵列，以响应于滚筒内的减小的空气压力而允许从滚筒外部到达滚筒内的气流。 一组阀可在关闭位置之间移动，在该关闭位置，该阀限制通道中的至少一个和相同通道的限制减小的打开位置。 当鼓的一部分区域被一片材料包裹时，与该区域的边缘相邻的通道阀中的至少一些是打开的，并且用于通道的阀未被片材覆盖并且不与该区域的边缘相邻 关闭。 在没有纸张的区域，鼓的开放面积被调节为小。 因此，滚筒的开口面积适应纸张的形状和尺寸以及鼓上的纸张位置，同时最小化所需的抽吸流量。 双面打印机具有两个这样的真空鼓组件，它们的鼓平行。 鼓内的空气压力减小，鼓反向旋转。 印刷材料被输送到第一滚筒并通过真空保持在第一滚筒上并随其一起旋转。 第一印刷头印在材料的一面上。 材料从朝向第二滚筒的方向从第一滚筒释放，并通过真空保持在第二滚筒上并随其一起旋转。 然后，第二打印头在第二鼓上的材料上打印。 然后将材料从第二鼓释放。

摘要： The present invention relates to an apparatus for singling flat material to be conveyed having a suction device, with openings in the suction device defining an area within which the suction device grasps the material to be singled. Known singling devices have in particular the disadvantage that operation of the suction device produces a high noise level which is felt to be very unpleasant. The present invention provides a shifted arrangement of the suction openings which leads at least to partial elimination of the noise during shifted activation of the suction openings.

摘要： A vacuum holddown has a holddown member with an outer surface for temporarily capturing a flexible sheet material via a vacuum force distributed across the outer surface through discrete vacuum channels. A vacuum force valving mechanism abuts an inner surface of the holddown member in a selectable sliding engagement. The valving mechanism has a pattern of apertures therethrough in predetermined pattern such that discrete valve mechanism positions produce discrete vacuum force patterns at the outer surface of the holddown member.
