For the most part, the belt types listed here meet
all requirements. Other belts are available on
Accumulating belts are designed for long-term
accumulated operation and have corresponding
surface properties (friction coefficient).
Belts with limited accumulation capability are not
designed for long-term accumulated operation.
Relative motion is permitted, e.g. when running up
against an end stop, in case of slight speed differences
from one conveyor to the next, or with transverse
movement of light loads (with laterally stiff

* The K1% value is the force with which the belt is stretched by 1% per mm of width.
It is an indication of the strength and therefore the load capacity of the belt.
** Depending on the batch, the colour of the belt may differ from the example in the photograph
in this catalogue.
The non-accumulating belts, also known as antislip
belts, have a structure or friction coefficient
that provides high grip.
