Abstract
Reinforced facings, including reinforcing webs entrained in hydraulic cement via a slurry bath, adhere to a nailable lightweight aggregate cementitious core to form a panel web. The reinforced web is formed on abutting conveyed carrier sheets, and the web is transversely cut, between the sheets, while moving or when stopped, in response to sensing of the sheets. The cut panels, on respective sheets are stacked for curing without damaging the panel edges and in a manner to minimize panel flex. Slurry bath, facing applicators, and cutter and stacking apparatus are included.
Claims5
A method of stacking flexible assemblies, each comprising an uncured cementitious panel carried on a carrier sheet, one atop another, comprising the steps of:
- conveying an assembly onto a drop table, said drop table comprising a plurality of drop panels supporting said carrier sheet and withdrawable therefrom to drop said assembly onto a stack of assemblies, said drop plates having tapered edges beneath said carrier sheets;
- withdrawing support from said carrier sheet, first from corners thereof and then form central portions thereof, to drop said assembly, all by sliding said drop plates horizontally from beneath said carrier sheet.
Apparatus for stacking a plurality of flexible assemblies one atop another, wherein said assemblies each include an uncured cementitious panel on a carrier sheet, said apparatus comprising;
- a drop table comprising a pair of drop plates for receiving an assembly,
- said drop plates being mounted for substantially horizontal reciprocal movement toward and away from each other,
- said drop plates disposed proximate each other for receiving an assembly, and being movable away from each other and from beneath a carrier sheet of the assembly to drop the assembly onto a panel stack,
- said drop plates having tapered edges beneath said carrier sheets, whereby when said drop plates are moved away from each other, corners of said carrier sheet and panel are dropped before central areas of same in order to minimize panel flex.
