Plate T-Type Joints

Plate T-type joints are used to connect board elements of the bodies of case fur­niture, in particular side walls, bottom boards and top surfaces with horizontal and vertical elements, as well as connecting elements between one another. This group of joints includes straight dowel joints, regular mortise and tenon joints, full spline mortise and tenon joints, sharp spline joints, full spline joints, fin unilateral joints, fin bilateral joints, spline joints and spline framed joints (Fig. 4.41). Plate X-Type Joints

Plate X-type joints occur only in places of joining of elements and interior walls of the bodies of case furniture, as well as places where honeycomb mesh fills of woodwork boards meet (Fig. 4.42).
