Some models are equipped with a Fabric Guard that mounts directly behind the Finger Plate. This Guard should be set as near to the finger as possible, but still allow space for the stitch to shed off the Finger. It also should be set as near to the Latch Hook as possible, but it never should contact the Latch Hook. The Guard helps the Latch Hook form the loops on the Finger Plate by controlling the shedding of the loops off the finger.
