To provide a conveying and positioning device for laterally conveying a long material to a conveyance table from both sides of the conveyance table, and preventing occurrence of a unprocessable portion of the material.
Under a state in which a long material (shape 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 shape steel A is conveyed forward. When a rear end portion of the shape steel A reaches a vicinity of the pinch roller apparatus 20, the rear end portion of the shape 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 shape steel A is conveyed forward through the pinch roller apparatus 20 and is positioned.
