Lath/leaf type air expanding shaft for winding unwinding machine
1.Product Introduction
The lath type air shaft is generally used in the case of winding (Rewinding thinner paper core) or thin paper tube of the slitter. Because the paper tube is thin and easily deformed. The lath type air shaft is bulged into three whole pieces of tile with good roundness. However, if a convex-type air expanding shaft is used, the paper tube may be broken if the air pressure is large. Compared with the key type inflation shaft, the lath type air expansion shaft has a small strength, a light loading weight.

3.Why choose us
1)We adopt hi-precision cold-drawn steel tube as the shaft body.The thickness of this kind of tube is uniform so when the rubber balloon inside is inflated , the three whole pieces of tile will stick out at same height .And it will greatly weaken centrifugal force of the whole air shaft when it is rotating and will keep a dynamic balance.
2)For the key strip,we adopt a whole piece of aluminum plate to make it.And it can form a good protective ring around the air bladder. We adopt the pagoda springs to support the air bladder which can bear 300000 compressions.
3)We are using a high power press machine which can produce 80T thrust to realize all the combination of spindle head and steel tube. While other suppliers knock the spind head into the steel tube with a big hammer,no quality and accuracy.
4)We have the quality control system during the whole production from the very beginning to the end and our principle is to make sure each shaft is qualified.
