Abstract

Plasterboard having a recess on both longitudinal edges (for jointing purposes) is made by feeding a plastic tape under each edge of the board as the board is being made in the usual manner by feeding plaster between two moving plies of paper. The plastic tape impresses recesses into the edges of the board and is kept in position until the plaster begins to set. Correlation of the motor speed with the rate of conveyance for punching and cutting operations is described with reference to Figs. 2-9, (not shown).
