SEAL STRIP PROCESSING METHOD AND SEAL STRIP PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a seal strip processing method capable of producing a large amount of seal strips at low cost.SOLUTION: A seal strip processing method comprises: a bending processing step of feeding a long thin plate of a material P1 to a bending processing part at a predetermined position at a predetermined speed, and obtaining a primarily processed material P2 by bending one side of the material P1 into an L-shaped cross-sectional shape by the bending processing part; and a pointed shape processing step of feeding the primarily processed material P2 to a pointed shape processing part at a predetermined position at a predetermined speed, performing pointing processing for processing the material P1 into a predetermined shape such that the other side of the material P1 is smaller than a longer side of an L-shaped cross-section of the primarily processed material P2 in the thickness of an end portion, and obtaining a secondarily processed material P3.SELECTED DRAWING: Figure 1
