Abstract: A line block is used for producing profiles on bodies, especially filled automobile bodies. The block is composed of a series of thin, stacked plates with fine cutting teeth along one edge of each plate. The plates are clamped together with bolts so that they can be loosened and pressed against a profile to be matched so that the cutting edges of the plates follow the profile. The bolts are then tightened and the line block used to produce the desired profile. Notches in the cutting edges of the plates are offset on adjacent plates in the block to accommodate material removed from the body being profiled.
