Abstract
An apparatus for vacuum coating continuous web materials has a housing with a removable cover disposed on at least one side for the hermetic closure of the housing, and a winding means having pulley cylinders, tension measuring cylinders, stretching cylinders and tightening cylinders journaled between two plates, plus at least one coating cylinder and at least one take-up roll and at least one feed roll, as well as a coating source held stationary in the housing. The two plates together with the cylinders and rolls are able to travel as a unit on a running gear for the purpose of loading and unloading, to such an extent that all cylinders are freely accessible from without. A transport means which can move transversely to the tracks of the running gear is provided with pairs of arms journaled on the running gear. The common pivot axis of the pairs of arms is disposed parallel to the tracks. The free ends of the pairs of arms are equipped with supporting eyes for holding one fresh roll and one take-up roll.
