Peeling machine

A peeling machine comprising:

• a cutter head configured to rotate about a substantially horizontal mechanical center line to cut a surface of a round rod-like work;
• and
• a feed mechanism configured to hold the work on the mechanical center line between upper and lower feed rollers and feed the work to the cutter head, wherein
• the feed mechanism includes:
• a first holder configured to rotatably support the lower feed roller and have an upwardly-extended first frame further than the upper feed roller;
• a second holder configured to rotatably support the upper feed roller and has a upwardly-extended second frame;
• a roller opening/closing driving mechanism configured to be disposed between the first and second frames and vertically move the first and second frames relative to each other;
• a synchronizing mechanism including a pinion disposed in the same vertical plane as axes of the both feed rollers above the upper feed roller, and first and second racks that are provided in the first and second frames, respectively, and engage with both respective ends of the pinion in a work feed direction;
• and
• a grasping-force applying cylinder disposed in the roller opening/closing driving mechanism to apply a downward work grasping force to the second holder,
• wherein
• two synchronizing mechanisms are aligned in an axial direction of the pinion,
• in one synchronizing mechanism, the first rack is disposed on the downstream side in the work feed direction, and the second rack is disposed on the upstream side in the work feed direction, and
• in the other synchronizing mechanism, the first rack is disposed on the upstream side in the work feed direction, and the second rack is disposed on the downstream side in the work feed direction.
