Claim 15:
16. A vacuum arrangement comprising:
a first dehydration chamber;
a substrate transfer chamber for receiving substrates in succession at a discontinuous movement speed and for providing the substrates in succession at an invariant movement speed to the first dehydration chamber, wherein the substrate transfer chamber is configured to convert the discontinuous movement speed to the invariant movement speed;
a second dehydration chamber connected to the first dehydration chamber via an always-open substrate transfer gap, wherein the always-open substrate transfer gap is dimensioned to permit transfer of the substrates through the always-open substrate transfer gap at the invariant movement speed from the first dehydration chamber to the second dehydration chamber, wherein the always-open substrate transfer gap is configured to form, in combination with the transport of substrates within the always-open substrate transfer gap, a gas separation between the first dehydration chamber and the second dehydration chamber;
a gas-transfer vacuum pump fluidly connected to the first dehydration chamber for evacuating the first dehydration chamber; and
a gas-binding vacuum pump fluidly connected to the second dehydration chamber for evacuating the second dehydration chamber.
