METHOD AND APPARATUS FOR CREASING FACING MATERIAL USED IN THE MANUFACTURE OF WALLBOARD

摘要

Aspects of this disclosure relate to a method of manufacturing wallboard which includes providing a first layer of facing material, creasing the first layer facing material intermittently to create a series of creased portions, providing a gypsum slurry on the first layer of facing material and providing a second layer of facing material over the gypsum slurry. Further, creasing the first layer of facing material intermittently can include intermittently creasing the first layer of facing material in a substantially linear fashion extending in a first direction of the first layer of facing material so that the first layer of facing material exhibits a linear series of creased portions extending in the first direction of the first layer of facing material and a series of portions that are not creased extending in the first direction of the first layer of facing material.

主权项

1. An apparatus for manufacturing wallboard comprising:
a feeder that advances a first layer of facing material along a wallboard production line; a first set of one or more creaser wheels positioned along the line adjacent a first edge of the first layer of facing material; a second set of one or more creaser wheels positioned along the line adjacent a second edge of the first layer of facing material; and a feeding source along the line that feeds a gypsum slurry onto the first layer of facing material, wherein each of the creaser wheels includes a series of notches and teeth and each creaser wheel creases the first layer of facing material by creasing portions the first layer of facing material and refraining from creasing other portions of first layer facing material as it rotates so that the uncreased portions of the first layer of facing material are positioned in line with the creased portions of the facing material and between the creased portions of facing material.
