Process and system for making an erosion control mat

A process for making an erosion control mat includes rotating a cylindrical drum having a plurality of mold cavities; depositing a paste into the mold cavities; selecting the sheet of mesh material to have sufficient tensile strength to join the blocks of hardened paste together without tearing or s...

Zusammenfassung:	A process for making an erosion control mat includes rotating a cylindrical drum having a plurality of mold cavities; depositing a paste into the mold cavities; selecting the sheet of mesh material to have sufficient tensile strength to join the blocks of hardened paste together without tearing or separating from the blocks of hardened paste, and to have sufficient density to retain the paste within the mold cavities as the drum rotates; covering an outer surface of the cylindrical drum and outer surfaces of the paste with the sheet of mesh material; continuing to rotate the cylindrical drum as the paste hardens into dimensionally stable blocks, and holding the sheet against the outer surface such that the sheet retains the paste within the mold cavities and the sheet becomes embedded in the paste; and separating the dimensionally stable blocks from the mold cavities.
