Pneumatic Shafts with SLATS (Type L)

These shafts have a single tube under each slat which makes them easy to maintain.

The slats are made out of longitudinal aluminium or gummed spring steel.

Shafts with persistant slats are used for winding and unwinding, especially for multi slit winding. Special applications in the extruder sector are able to realize as well.

Several applications ask for semi pivoted shafts. Those tasks can also be managed by shafts with slats, making the relation between expansion range and total length an advantage.

Axial adjustable shafts are not only useful in the label printing industry, but also if web correction becomes necessary.

It is optional to equip the shafts with rollers between the slats to assist in the removal of heavier products. In decompressed condition, the rolls have contact to the internal core diameter and support its removal. Have a look to practice.

This is an example how during the process with constantly changing diameters, complete solutions, by the use of quick-change systems have been realized.
