Mechanized devices, comprising pull levers or pedals; a large rotating dial; and a series of looping points (needles), designed to smoothly fuse two parts of a knitted garment or stocking together in a flat and invisible seam. By piercing each garment parts' looping line, or line of stitches along which the seams must be set by the looping machine, the device allows users to precisely trim any surplus stock away from the loops before executing the seam.
