Abstract
This invention discloses a method of bending a band knife, comprising the step of forming a bent portion of a predetermined angle on a band knife (1), which is sent out intermittently from an outlet of a mold (20), by using a push member (22) which can be moved a predetermined width, and a molding surface (21) provided at the outlet of the mold (20), while the feeding of the band knife (1) is stopped, whereby a desired arcuate shape can be easily obtained.
