Banding packing machine

A banding packing machine having left, right and middle presser members which are sequentially moved vertically by a cam mechanism, wherein a tip portion of a band is clamped, returned from a band feeding side and is tightened and a band portion superpositioned above the tip portion is melted by a heater and the band feeding side is cut and bonded to the tip portion as the molten portion solidifies, the improvement comprising:

• the left, right and middle presser members having drum portions having a cylindrical shape, wherein the drum portions of the right and left presser members each have a flat, planar surface formed thereon, extending substantially parallel with a longitudinal axis of each of the presser members, wherein the drum portion of the middle presser member has a pair of flat, planar surfaces formed thereon, extending parallel to each other and parallel to a longitudinal axis of the middle presser member, and wherein the planar surfaces of the right and left presser members slidably engage the respective pair of planar surfaces of the middle presser member for sequential vertical movement caused by said cam mechanism, whereby relative rotative movement of the presser members is prevented.
