This because there is no other card numbered 333 or lower in any of the other storing devices 23, 24, 25 and 26.
  • the next card 339 in pile 13 is simultaneously picked up and stored in storing device 25.
  • the next lowest sequential card is numbered 334" and is the second card in pile 14 which is now stored in the storing device 28 where it now i passed by the combining device 31 through combining device 30 and thence immediately on to the stack in holder 32 by the combining device 29.
  • the pick-up device 18 picks up the next card or 333a from the pile 14 and it is placed on the storing drum 26.
  • This number 333a however is now less than 334, in that a card numbered 334 has already been deposited on the stack in holder 32.
  • this wrongly ordered card 333a in pile 14 is passed on to the combining device 31, but it is not passed on to the combining device 30. It is instead immediately transferred into the discharge trough 34 as card C.
  • a similar discharge trough 33 is provided cooperating with combining device 27.
  • any card which is out of order in any of the piles 11, 12, 13 or 14 is automatically discharged into the discharge receptacles 33 and/or 34 through the control of the separate distributor switches 1220 operating on the control devices 130 and 131 as shown in FIG. 3.
  • Pile 14 has now been emptied according to the above table, but if another card remained therein, it would immediately be taken off and placed on the storing device 26 for further collating.
  • the next number in sequence is 335, but since there is no card 335, the device searches on for the next sequential number, which is card 336 now stored on the storing device 23. This card 336 is then transferred by the combining devices 27, 28, and 29 on to the final stack in holder 32.
  • Card 339 is the next and last card to be collated and it is now stored in storing device 25 from whence it is now transferred through combining device 31, combining device 30, and combining device 29 on to the stack in holder 32.
  • the stack in holder 32 contains the following cards in the following order:
  • control means connected to each of said takingoff means, each of said reading means, each of said i4; storing devices, and each of said combining devices for controlling their operation in accordance with the sequence of the numerical data read from each sheet, (I) said control means including a number evaluating device,
  • (K) means controlled by said number evaluating device for discharging sheets in said associated receiving means which are not in said sequential order
  • a device according to claim 1 wherein said rotating drum storing devices and said rotating drum transferring devices are half the diameter of said rotating drum takeoff means and said rotating drum combining devices.
  • each said drum means comprising a cylindrical roller with a radial suction channel therein for holding said sheets to the periphery of said roller,
  • each of said rotating drum storing devices comprising a cylindrical roller with a radial suction channel therein for holding said sheets to the periphery of said roller,
  • n first rotating drum combining devices wherein n is the smallest whole number equal to or greater than n/2, associated with two of said rotating drum storing devices for removing said sheets from said rotating drum storing devices, each of said rotating drum combining devices comprising a cylindrical roller with a radial suction channel therein for holding said sheets to the periphery of said roller,
  • each of said second rotating drum combining devices comprising a cylindrical roller with a radial suction channel therein for holding said sheets to the periphery of said roller,
  • control means including valves for controlling the suction in said channels in each of said rollers, said control means being connected to each of said takeoff means, each of said reading means, each of said rotating drum storing devices, and each of said combining devices, and each of said transferring devices, for controlling their operation in accordance with the sequence of the numerical data read from each sheet, said control means comprising:
  • valve control circuits for controlling said 16 valve for operating said taking-01f means, said rotating drum storing devices, said combining devices, and said transferring devices, and (f) distributor means connected from said detec- 5 tor and said numerical number evaluating device for controlling said valve control circuits, whereby said sheets are retained on said rotating drum storing devices until they can be transferred to said final holding means in a sequential order of the numerical data read from said sheets, and if a stored sheet is not in sequential order to discharge it in said associated receiving means; and wherein the minimum surface distance over said drum from any pile to said final holding means is substantially the same.
