Abstract
Under a state in which a long material (structural steel (A)) is sandwiched by pinch rollers (drive roller (21) and idle rollers (22)) of a pinch roller apparatus (20), the drive roller (21) is driven to rotate, and the structural steel (A) is conveyed forward. When a rear end portion of the structural steel (A) reaches a vicinity of the pinch roller apparatus (20), the rear end portion of the structural steel (A) is held by a holding portion (32) provided at a front end portion of a feed bar (36) of a feed bar device (30), and the feed bar (36) is caused to slide toward a working machine. Consequently, the structural steel (A) is conveyed forward through the pinch roller apparatus (20) and is positioned.

A long-material conveying and positioning apparatus, which conveys a long material to a working machine along a longitudinal direction of the long material, comprising:
- a pinch roller apparatus which comprises pinch rollers formed of a plurality of rollers including at least one drive roller, and conveys the long material toward the working machine by driving the drive roller to rotate under a state in which the pinch rollers sandwich the long material;
- and
- a feed bar device comprising
- a feed bar extending in a conveying direction of the long material,
- a support portion for supporting the feed bar to allow the feed bar to slide in the conveying direction, and
- a holding portion provided at an end portion of the feed bar on a side of the working machine, for holding the long material, the feed bar device allowing the feed bar to slide until the holding portion passes the pinch roller apparatus to reach a desired position in an inside of the working machine.
