The present invention relates to a two-pattern quilting machine composed so that a weight bar (18) can be installed between front and rear quilting main bodies (16, 20) to give proper tightness to a quilting fabric (36) while rising along right and left vertical LM guides (22, 24). The weight bar (18) is combined with chains (30, 32), which are installed and fixed next to the right and left vertical LM guides (22, 24), by chain sprockets (26, 28) at both sides thereof, and gives wholly constant tension to the quilting fabric (36) while always keeping horizontal even if concentrated force is exerted by gravity, the quilting fabric (36) or the like during rise, thereby preventing the distortion of a quilting pattern by difference in tension that is applied to the quilting fabric by the weight bar (18). |
