1. Inflatable job a short time, separated from the inflatable Key type air shaft and place the paper tube just three seconds to
inflate and deflate, nor do they need any parts sub negligent shaft side that is able to work closely with the paper tube bite.
2. Paper tube placement simple: inflatable and deflated operation, mobile and fixed any position paper tube in the axial plane.
3. Carrying heavy: May be the actual needs of customers, to determine the size of the shaft diameter, and the use of high
strength steels hard to make it carry the weight increase.
4. Economic efficiency: shaft design for a particular function, for thick, thin, wide, narrow tubes have encountered all kinds of
paper of all applications.
5. Maintenance is simple, use a long time: a single film blowing machine inflatable Key type air shaft parts, each part in its
construction fixed specifications, can exchange it with, it is convenient.
