摘要： A device for coating webs of material traveling over a backing roll to a controlled thickness, in which the coating material can be applied to the web with a slotted nozzle that extends over the total width of the web and in which the nozzle has an initial-flow regulation gap downstream of which a flow-regulation lip and an excess-removal lip demarcate a flow-regulation chamber. To allow more uniform and higher-quality application of the coating medium and, in particular, to ensure heavier coating weights and improved web printability with simple means, a barrier that demarcates the flow-regulation chamber from the traveling web of material is positioned to the vicinity of the excess-removal lip. The barrier can consist of a knife-like sheet-metal spring, of a roll, of a strip, or of a jet directed opposite to the direction in which the web is traveling. The barrier prevents an isolating layer of air from penetrating into the flow-regulation chamber.

摘要： A method of winding webs of cellulose on core tubes, wherein the web, which is subjected to tension, is separated by being wetted along a line across the direction in which the web travels at a point that ensures that the core tube will be completely looped. A two-drum winding machine with contact roll and web-separating mechanism for winding webs of cellulose is provided with a hollow separating strip that extends across the whole width of the machine and has water outlets along its blade.
