Abstract:

The described embodiment of an edge-of-part (EOP) scribe device is operative to simultaneously scribe opposed trim lines in an oversized, cured leading-edge sheath mounted on a sheath mold assembly. The EOP scribe device includes a primary carriage assembly having rollers secured thereto wherein the primary carriage assembly is translatable along side rails secured to the sheath mold assembly, opposed pairs of guide rails affixed to the primary carriage assembly, and a secondary carriage assembly mounted in movable combination with each pair of guide rails. Each secondary carriage assembly includes a spring-loaded scribe head for inscribing a trim line in the cured leading-edge sheath, a rigid follower linkage secured to the secondary carriage assembly, and a follower slide roller mounted in rotatable combination with the rigid follower linkage and operative to rotatably engage a trim line template mounted on the sheath mold assembly. As the primary carriage assembly is subjected to translation along the sheath mold assembly, dimensional changes in the trim line templates induce vertical displacements in the follower slide rollers, the induced vertical displacements being coupled through the rigid follower linkages to cause corresponding vertical displacements in the secondary carriage assemblies and concomitantly, in the scribe heads. The vertical displacements of the hardened scribe heads matches the respective trim line templates such that the scribed trim lines correspond to the profiles of the finished edges of the prefabricated leading-edge sheath.
