Abstract
Official abstract text for this publication.
A cutting method of the invention cuts a flat wire covered with a film, using a pair of first blades, and a second blade that is arranged between the pair of first blades. This cutting method includes a step of forming tapered cuts in an upper surface of the flat wire, by the pair of first blades cutting part way into the flat wire in a thickness direction, from the upper surface of the flat wire, and a step of cutting the flat wire by the second blade, between the two cuts, so as to form a chamfer on both side surfaces next to the upper surface of the flat wire.
First claim
Opening claim text (preview).
What is claimed is: 1. A cutting method for cutting a flat wire covered with a film, using a pair of first blades, and a second blade that is arranged between the pair of first blades, comprising: a step of forming tapered cuts in an upper surface of the flat wire, by the pair of first blades cutting part way into the flat wire in a thickness direction, from the upper surface of the flat wire; and a step of cutting the flat wire by the second blade, between the two cuts, so as to form a chamfer on both side surfaces next to the upper surface of the flat wire. 2. The cutting method according to claim 1 , further comprising: a step of precutting the film along the outer periphery of the flat wire, after cutting the flat wire; and a step of pulling the precut film off of the flat wire. 3. The cutting method according to claim 2 , wherein the film is precut by moving a round blade along the outer periphery of the flat wire in the step of precutting the film. 4. A cutting tool that cuts a flat wire, comprising: a pair of first blades; and a second blade arranged between the pair of first blades, wherein a tapered surface that becomes thinner toward a tip end side is formed on a tip end portion of each of the two first blades; the tapered surfaces of the pair of first blades are arranged so as to come closer to each other farther toward the tip end side; and an inclined surface to provide a chamfer on both side surfaces of the flat wire is formed on the second blade.
