Abstract: A heating, ventilation and/or air conditioning unit (10) for a car is specified, having a first air guide (22) for guiding a first, cold air stream and having a second air guide (24) for guiding a second, warm air stream which is separate from the first air stream, wherein a heating device (26) for warming the second air stream is arranged in the second air guide (24). The heating, ventilation and/or air conditioning unit (10) furthermore has a first mixing chamber (28) and a second mixing chamber (30), wherein the first mixing chamber (28) and the second air guide (24) each have at least one inlet opening (32, 34) to the second mixing chamber (30).

Abstract: The invention relates to a book production line and a method for producing individual books as well as very short and short runs of books. The book production line comprises a feed device and a following transport section for book covers, a feed device and a following transport and processing section with a rounding and pressing machine, an adhesive-backing apparatus for book blocks, and a casing-in machine. The rounding and pressing machine forms an upstream-arranged, first adjustment segment. The adhesive-backing apparatus is divided into at least two additional adjustment segments that successively follow each other in a transport direction of the book blocks. Each adjustment segment includes a separate drive and a number of book block positions which is the same for each adjustment segment or differs maximally by three book block positions.
