摘要： A blast air control device for a sheet feeder with a device for the cyclic control of the blast air, which comprises a first device for the cyclic control of blast air and a second control device controlled by the feeder output as an input variable and associated with the first device. Means for regulating at least one of the pressure of the blast air and of the blast time over a wide output range of the feeder are provided in order to maintain automatically the optimum blast action.

摘要： The disclosure pertains to a document hopper separator mechanism which is wholly pneumatically actuated to feed documents serially from the bottom of a document deck disposed therein. Riffle jets introduce air to support the deck and separate the lowermost documents from the document guide surface and one another while selectively operable eject jets function to eject the lowermost document from the hopper to a transport mechanism.

摘要： A sheet-separating apparatus is provided for use in conjunction with vacuum fingers for feeding sheets seriatim from a stack. The sheet separator comprises a plurality of stationary hollow tubes adjacent one end of a sheet support, each tube having an orifice in the form of a vertical slot facing the support. Air is supplied to each tube and is directed in a stream through the slot by an oscillating riffling finger associated with each tube and having a tab extending into the slot to vary the effective area thereof. When the riffling finger is in a lowered position against the top of the stack, air is forced through a small area of the slot at a high velocity to separate the edges of the upper sheets as a vacuum finger engages the uppermost sheet. As the riffling fingers move upwardly from the stack the effective area of each slot becomes larger, causing a gradual decrease in the velocity of the air and a gradual increase in volume. After the vacuum fingers have separated the uppermost sheet from the stack the riffling finger moves downwardly to grip the remaining sheets on the stack.

摘要： Apparatus for the pneumatic feeding of individual sheets from a sheet stack to printing machines, in which the drive is derived from a driving shaft, the axis of which is parallel to the sheet stack and in direction of supply of the sheets. The driving shaft supports a number of cams transmitting motion to individual mechanisms of the feeding device and controlling vacuum and pressurized air supply for different functional purposes which are all located in a common housing.
