Quality of Pneumatic Cloth
By Thomas Henden
As I'm going to change the pneumatic cloth on my pneumatics, I discover that the new cloth has a very "dry" surface, and is stiff when glued on the pneumatics. (Not because any hot glue is spilled.
The surface is not completely black, and turns grey when exposed to pressure. Some rubber comes off when rubbed not forcefully with a fingernail.
I was expecting a rubber surface more like tyres, black, and sticky, (when the talcum powder's removed), and more shiny and smooth than this cloth is.
The penumatics are not completely airtight, and are stiffer than the old ones, although much more airtight than them. Some of the stiffness seems to be "softened" by opening and closing the penumatics several times.
Has this cloth been stored by the manufacturer for several years, or is this normal? Should I send a sample of the cloth back, and complain?
Sincerely Thomas Henden, Norway.
