The flex axle roller is made with two pivoting axles. Mounted on each axle are seven steel star rollers (14 total). As the roller is moved forward and backward, the axles pivot outwardly then inwardly. This action mixes the carpet fibers and pulls the seam edges closer together for less visible seams. The star wheels press the carpet's backing into the hot melt adhesive. Roller area width is 4" total. Net weight: 10 oz.
