Abstract
A method of manufacturing bricks with smooth surfaces includes the steps of providing a mould container with a movable bottom, washing the mould container, placing a layer of releasing material in the mould container, filling the mould container with clay and trimming off the container. Only the bottom of the container is filled with a releasing material and the bottom of the container is moved so that it is virtually outside of the mould container.
Claims1
Method for manufacturing green bricks with smooth side surfaces, using a mould container with side walls and a movable bottom, comprising washing said mould container with excess water such that said side walls of said mould container are moistened, and while keeping said side walls moist placing a releasing material layer of sand or sawdust only on said movable bottom and then filling said mould container with clay, then trimming excess clay from said mould container, and moving said bottom so that it is virtually outside said mould container while said side walls are kept moist to form a green brick with smooth side surfaces due to the absence of said releasing material layer on said moist side walls.
