There are provided a process and an apparatus for detecting loop stitches of a tubular knitted fabric and an apparatus for linking the tubular knitted fabric, which can automatically detect each of loop stitches formed in the tubular knitted fabric. According to the process for detecting the loop stitches, the tubular knitted fabric is extended by inserting a penetration element through the interior of the fabric having the loop stitches, and a multi-gradation image including an image of the loop stitches of the tubular knitted fabric extended by the penetration element is picked up. The locations of the loop stitches are detected by processing the multi-gradation image. The apparatus for detecting the loop stitches includes the penetration element, an image pickup device for picking up the multi-gradation image, and a loop stitch detecting section for detecting the locations of the loop stitches by processing the multi-gradation image.
