Definitions

• the drying of the running web is rather important if the web is coated with a coating substance, which includes water as the fluency element.
• a coating substance which includes water as the fluency element.
• water maintains the fluency property of the substance and, hence, faciliates an incomplicated and easy working phase.
• a commonly used substance concentration includes about 40% of water, which must be removed from the levelled coating layer and the running web, in which a portion of the water amount has penetrated.
• a typical method to dry the web is to blow air streams either against or parallel to the web so, that the web is maintained contactless from air stream supply boxes, and preferably at a predetermined fixed distance from them.
• Unit 8 can also be in co-operation with a reflector 14 so that web 3 is running between unit 8 and reflector 14.
• web 3 is pre- and posttreated with a measure, which accelerates the vapour motion away from the vicinity of the web, which in turn decreases the saturation level near the web.
