Abstract
An automatic brickwork stencil making machine formed in two production lines on a table top base. A roll of adhesive coated tape in each line is processed to pick up tabs positioned perpendicular to the moving tape, a tamper secures the tab on the tape, and a take-up spool driven by a motor rolls up the completed product for use in making brickwork layouts on vertical or horizontal planar surfaces.
