Abstract

A work piece setting apparatus including a sensor for detecting patterns of two work pieces, two holders for holding the cloth pieces, a moving device for moving the lower holder, a rotator for rotating the lower holder, a calculator for calculating a mismatch amount for the patterns according to signals detected by the sensor and a controller for controlling the moving device and the rotator according to the mismatch amount. The lower work piece is moved and rotated with the lower holder and the patterns of two work pieces are matched. After the work pieces are matched and set, a carrying device carries the work pieces to a sewing position from a setting position on a work table.
