The invention relates to an arrangement for changing a winding drum in a take-up or feed-out chamber of a coating installation for web-form material. One such arrangement can be provided on both sides of a coating chamber, the one arrangement serving as a take-up drum and the other arrangement as a feed-out drum. The arrangement comprises two tracks for receiving end bearings of a winding drum, the tracks being comprised of two parts, of which the one part is stationary and the other is pivotable. The arrangement is located in a housing with a door. If the winding drum is to be replaced, the door is opened and the pivotable parts of the tracks are folded outwardly such as that they project from the housing. Onto the projecting track parts a winding drum can now be placed, it can subsequently be slid inwardly and be arrested.
