4'' 5'' 6'' air sleeves can be installed on 3'' main shafts. From the customer's point of view, they are not used often, but when there is an order for 4-6'', there is no need to purchase 4-6'' air shafts to complete the work. Inflate the 3'' air shaft to make the pair of air sleeve expansion strips on the air shaft tighten the paper tube.
In addition, since the retraction and extension of the cam is controlled by air pressure, it is very convenient to load and unload the coils; because of the special sealing and pressurization method, there is no rubber airbag on the inner page of the main body and almost no maintenance is required.
