Abstract
Methods and systems of roll coating are provided. An applicator applies a liquid material onto a receiving roll to form a liquid pattern, which is then directly or indirectly transferred onto a substrate surface under an impression force to form a continuous coating on the substrate surface.
Claims19
A method comprising:
- premetering a liquid material onto a receiving roll to form a discontinuous liquid pattern;
- and
- transferring at least a portion of the liquid material in the discontinuous liquid pattern from the receiving roll onto a major surface of a web to form a continuous coating;
- wherein premetering the liquid material onto the receiving roll comprises applying a coating volume of the liquid material to the receiving roll to proportionally control a thickness for a given width of the continuous coating on the major surface of the web.
1 more element
A coating system comprising:
- a receiving roll;
- an applicator configured to premeter a liquid material onto the receiving roll to form a discontinuous liquid pattern;
- and
- a web engaging with the receiving roll such that at least a portion of the liquid material in the discontinuous liquid pattern from the receiving roll is directly transferred onto a major surface of the web to form a substantially continuous coating,
- wherein when premetering the liquid material onto the receiving roll, the applicator is configured to control a coating volume of the liquid material applied to the receiving roll to proportionally control a thickness for a given width of the continuous coating on the major surface of the web.
2 more elements
A coating system comprising:
- a receiving roll;
- an applicator configured to premeter a liquid material onto the receiving roll to form a discontinuous liquid pattern;
- a web transfer roll, wherein the web transfer roll directly engages with the receiving roll to receive at least a portion of the liquid material from the receiving roll;
- and
- a web engaging with the web transfer roll such that at least a portion of the liquid material on the web transfer roll is transferred onto a major surface of the web to form a substantially continuous coating,
- wherein when premetering the liquid material onto the receiving roll, the applicator is configured to control a coating volume of the liquid material applied to the receiving roll to proportionally control a thickness for a given width of the continuous coating on the web transfer roll and the major surface of the web.
3 more elements
A coating system comprising:
- a receiving roll;
- an applicator configured to premeter a liquid material onto the receiving roll to form a discontinuous liquid pattern;
- a web transfer roll, and one or more intermediate rolls between the receiving roll and the web transfer roll, wherein the web transfer roll indirectly engages with the receiving roll via the one or more intermediate rolls, to receive at least a portion of the liquid material from the receiving roll;
- and
- a web engaging with the web transfer roll such that at least a portion of the liquid material on the web transfer roll is transferred onto a major surface of the web to form a substantially continuous coating,
- wherein when premetering the liquid material onto the receiving roll, the applicator is configured to control a coating volume of the liquid material applied to the receiving roll to proportionally control a thickness for a given width of the continuous coating on the web transfer roll and the major surface of the web.
