Gypsum board forming device with improved slurry spread

摘要

Disclosed is a gypsum board forming device which provides improved slurry spread. The device includes a forming table with an arcuate or angled profile that promotes a uniform slurry spread. An arcuate or angled hinge plate can also be included to further promote the uniform distribution of slurry prior to an extrusion plate.

主权项

1. A gypsum board forming device for facilitating slurry spread prior to a pinch point, the device comprising:
a gypsum slurry mixing device including first and second slurry outlets; a first forming table having an upper surface; a lower supply roll supplying a bottom facing sheet to the upper surface of the first forming table, the first slurry outlet supplying slurry over the bottom facing sheet; a roll coater positioned along the first forming table and configured to spread the gypsum slurry over the bottom facing sheet; a second forming table having a first arcuate cross section, the first arcuate cross section defined by a raised central area and lower side edges, the second slurry outlet supplying additional slurry to the bottom facing sheet along the second forming table, the first arcuate cross section configured to promote a uniform distribution of the slurry to the lower side edges of the second forming table; a third forming table having a second arcuate cross section defined by a raised central area and lower side edges, the first arcuate cross section being greater than the second arcuate cross section.
