Specifications: This machine is newly researched and designed by our factory based on the model of combined cam. It winds up the plastic tape by the back and forth movement of the swinging stem driven by the cam. It takes less effort and it runs more stable. With less friction factor and longer durability, the prime motor is 60% less in requirement of power consumption. It adapts to bobbins of Φ38×230mm, and it is the ideal mate of SJ-L series plastic tape extruder.
