摘要： An apparatus for feeding sheets of material, such as paper, sequentially from the bottom of a stack of sheets comprises a suction chamber, a perforated belt movable over the suction chamber, a sheet restraining gate above the downstream end of the suction chamber, and a roller to produce an upward corrugation in the bottom sheet only of the stack. The gap between the bottom of the gate and the belt is profiled to match the corrugation in the bottom sheet to enable the bottom sheet only to pass through. The profile preferably includes a shallow triangular recess in the bottom edge of the gate.

摘要： A conveyor belt for transporting articles having a plurality of apertures therein such that a vacuum applied to the apertures aids in forcing articles to stay on the conveyor belt while the articles are being translated. The conveyor is particularly useful for moving sheet articles such as a sheet feeder removing sheet articles from the bottom of a stack of sheet articles in a sheet feeder. The vacuum adds to the frictional force of the article on the conveyor belt and increases the productivity of the sheet feeder by reducing jams and increasing the frictional contact of the sheet article on the conveyor belt by removing chaff and other material form the conveyor belt.
摘要翻译：一种输送带，用于输送其中具有多个孔的物品，使得施加到孔的真空有助于在物品被翻转时迫使物品停留在传送带上。输送机特别可用于移动片材制品，例如片材进给器从片材进给器中的片材制品的底部移除片材制品。真空增加了物品在传送带上的摩擦力，并且通过从输送带上移除谷壳和其它材料，减少了卡纸并增加了纸张在输送带上的摩擦接触，从而提高了纸张供给器的生产率。

摘要： A sheet feeding apparatus to control the injection quantity of air to a document bundle and to allow a stable supply of paper regardless of the document size, document quantity or curling of the document. In the case where air is blown by a separation air injection unit against the front edge of a document loading unit, document-floating sensors are provided protruding upward from a sheet feeding belt. The floating sensors can be for example contact-type sensors such as microswitches to set that injection amount of air to an optimum injection amount of air when the state of the floating sensors, changes compared to their initial state.

摘要： Paperboard sheets are fed by a feeder including driven wheels which engage the lowermost sheet of a stack and drive it through the nip rolls of a box-finishing machine is synchronism with the latter. Supporting the sheets is a grate movable between a raised position wherein the wheels are spaced from the sheet and a lowered position wherein the lowermost sheet engages the wheels and is fed thereby to the nip rolls. Below the grate is a vacuum box for holding the sheet on the wheels. Raising and lowering of the grate is effected by a cam which may be adjusted to vary the feed stroke in accordance with the length of the sheets. For driving the wheels there is provided a dual input drive mechanism including a constant velocity input drive and a variable input drive which are resolved at a single output drive to the wheels. The output drive varies in velocity such that when the wheels initially engage the sheet, the wheels are at nearly zero or absolute zero velocity and subsequently the wheels reach a constant velocity for driving the sheet at said constant velocity which is matched with the surface velocity of the nip rolls. In an alternative embodiment, the feeder may be adjusted to feed either a single sheet or a plurality of sheets per cycle of the associated box-finishing machine.

摘要： Apparatus for feeding sheets from a stack of sheets on a sheet stack supporting tray which includes a sheet transport for feeding sheets from the tray. An air knife is disposed adjacent the front wall of the tray to inject air between the sheet to be separated and the remainder of the stack. The air knife includes at least one elastomeric member attached to its front wall that extends to a point immediately above, below or touching the sheet transport in order to inhibit multifeeding of sheets from the tray.

摘要： A bottom vacuum corrugation feeder includes a vacuum chamber with a bi-level support surface that support a plurality of apertured belts. The bi-level support surface has a series of raised members on a portion of its surface that corrugate the bottom sheet of a stack of sheets that are supported on a stacking tray. The stacking tray inclues raised members on its stack support surface that allow the venting of air from an air knife positioned in front of the sheet stack for separating the bottom sheet in the stack from the remainder of the stack. Recesses are included in the stack support surface of the stacking tray in order to reduce vacuum leak around the front edge of the sheet stack.

摘要： A system for measuring the friction between the bottom two sheets of the stack. The bottom-most sheet is held to a vacuum corrugation feeder tray by any suitable means such as a vacuum and moves with the tray. The vacuum corrugation feeder tray is mounted on compliant supports and driven near or at its resonant frequency by an electromechanical driver. At low or zero air knife pressure, the paper stack is mechanically coupled to the tray and moves with the tray, possibly slipping at some point during the vibration cycle. As the air knife pressure increases, the mechanical coupling decreases, and a point is reached at which the stack remains stationary. Prior to the point where stack motion ceases, the resonance of the tray is modified and it is possible to estimate the weight of the stack. When the stack motion ceases, the frictional force F can be estimated from the driving force required to maintain a given vibrational amplitude. From the driving force required to maintain a given vibrational amplitude and the mass of the tray or stack, it is possible to calculate the coefficient of friction between the bottom two sheets. The coefficient of friction is then used to control the amount of air pressure from the air knife until an optimum coefficient of friction is achieved.
摘要翻译：用于测量堆叠的底部两片之间的摩擦力的系统。最底部的片材通过任何合适的方式（例如真空）被保持在真空波纹进给器托盘上并与托盘一起移动。真空波纹馈送托盘安装在柔性支撑件上，并通过机电驱动器在其谐振频率附近驱动。在低或零气刀压力下，纸堆被机械联接到托盘并与托盘一起移动，在振动循环期间可能在某一点滑动。当气刀压力增加时，机械联轴器减小，并且达到堆栈保持静止的点。在堆栈运动停止之前，托盘的共振被修改，并且可以估计堆叠的重量。当堆栈运动停止时，摩擦力F可以从维持给定振动振幅所需的驱动力估计。从维持给定振动幅度和托盘或堆叠质量所需的驱动力可以计算底部两张纸之间的摩擦系数。然后将摩擦系数用于控制来自气刀的空气压力的量，直到达到最佳的摩擦系数。
