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.
Claims8
An adjustable line block for finishing a profiled surface of a workpiece, said line block comprising:
- a plurality of stacked plates each having an elongate cutting edge;
- a plurality of notches uniformly spaced along the cutting edge of each plate;
- a plurality of symmetrical cutting teeth formed in the cutting edge of each plate between each two adjacent notches, the teeth of each plate being aligned along the cutting edge for simultaneous engagement of the teeth with the profiled surface;
- means for holding the plates together with their cutting edges parallel and with adjacent notches in the cutting edges of adjacent plates offset from one another in the direction of the cutting edges, while permitting relative movement of the plates transversely of the cutting edge;
- and
- means for clamping the plates together to prevent relative movement thereof.
A cutting plate for an adjustable line block comprising a flat plate having an elongate cutting edge with notches uniformly spaced along the cutting edge, at a predetermined pitch length and respective pluralities of cutting teeth on the cutting edge between each two adjacent notches, the pluralities of teeth being aligned along the cutting edge, a pair of parallel, elongate slots through the plate perpendicular to the cutting edge, the slots having a centre-to-centre spacing in a direction parallel to the cutting edge of (X+1/2)L where X is an integer and L is the pitch length of the notches.
