<p>Used plastic strapping is recycled by feeding successive lengths of strapping to a cutter station that cuts off leading and trailing end portions of the strapping to provide 'clean' ends, and cuts out any old lap-joints. The resulting sections of strapping are heat-sealed together to form 'new' continuous strapping that is wound onto a spool for re-use. A single cutter head having upstream and downstream cutters is used to perform all cutting operations. The two cutters move downwardly together and either cut out a lap-joint or a leading or trailing end portion of a length of strapping, depending on what portion of strapping is positioned below the cutter head.</p> |
