First Claim
1. A dryer for drying a continuously conveyed product or a warp with a first dryer arrangement and a second dryer arrangement, the first dryer arrangement and the second dryer arrangement comprising side walls, and forming a passage through which the product is conveyed, whereinthe first dryer arrangement and the second dryer arrangement are movable relative to one another in a manner such that the passage in a first, stoppage position has a larger cross section than in a second, operational position, the first and the second dryer arrangements are arranged above one another, the second dryer arrangement is liftable, the first dryer arrangement and the second dryer arrangement remain essentially parallel to one another in said first position, and a gap is formed between a lower edge of the side walls of an upper dryer arrangement and an upper edge of the side walls of a lower dryer arrangement, said gap being essentially sealed in the second position, and open in the first position.

Abstract
The invention relates to a dryer (1) for drying continuously conveyed products, e.g. a warp, comprising essentially a first dryer array (2) and a second dryer array (3). A passage (4) for passing through the product (W) is formed between the dryer arrays (2, 3). The second dryer array (3) is configured in such a way as to be able to move in relation to the first dryer array (2). When the dryer (1) is in stop position (S), the second dryer array (3) is disposed relative to the first dryer array (2) in such a way that the cross section of the passage (4) is bigger than in the operating position (B).
