Method and apparatus for manufacturing continuous fiber glass strand reinforcing mat

摘要

The subject matter of this invention relates to a method and apparpatus for making mats of continuous glass fiber strands in which a heated calendering roll and continuous belt are used to compact the mat, expel excess noisture, melt, and/or cure resin previously distributed throughout the glass strand. The resin may be deposited in the mat in the form of a powdered resin or as continuous thread of material that is combined with the remaining strands that form the mat as the glass strands are projected onto the surface of a moving conveyor to form the mat.
