Abstract
A reinforcing web has multiple fibers joined together with a binder. At least some of the fibers have foldable portions, wherein the foldable portions have substantially less binder thereon to increase flexure to fold the web. A method of making the reinforcing web includes, applying a binder on the web, and removing some or all of the binder from a foldable portion of the web prior to curing the binder that remains on the web.
Claims37
A method of making a reinforcement web, comprising:
- assembling reinforcement fibers to form a precursor of a web;
- dispersing a binder composition among the fibers either before or after the fibers form the precursor;
- varying the amount of the binder composition in respective sections of the precursor, wherein different sections of the precursor have different amounts of the dispersed binder composition;
- and
- curing the binder composition to form the web having the fibers joined together by a cured binder composition, wherein different sections of the web have different amounts of the cured binder composition to adjust flexibility of the different sections of the web.
A reinforcement web, comprising:
- multiple reinforcement fibers joined together by a binder composition and forming a web;
- and
- the binder composition being dispersed among the fibers, wherein the fibers in different sections of the web have different mass distributions of the binder composition to adjust the flexibility of the different sections of the web.
A reinforcing tape for imbedding in a joint compound, comprising:
- multiple fibers joined together by a binder composition and forming a thin non-woven web;
- at least some of the fibers having one or more foldable portions, wherein the foldable portions extend in a lengthwise central section of the web;
- and
- the foldable portions having substantially less binder composition thereon to form a crease when folded.
A method of making a reinforcing web, comprising:
- applying a binder composition onto multiple fibers, wherein the fibers are oriented in multiple directions to form a non-woven web;
- removing at least some of the binder composition from foldable portions of at least some of the fibers, wherein said foldable portions are rendered capable of forming a crease upon being folded;
- and
- joining the fibers to one another by curing the binder composition.
