Climbing drum peel unit comprising a flanged drum with integral clamp for holding the free end of the test assembly.
The opposing end is attached to the loadcell. The drum is made to rotate by applying tension to the chains attached to the outer rims. This action produces a peel action on the adhesive bond. For ease of handling, the drum assembly is supported with Bowden cables.
This unit is compatible with ST series of benchtop material testing machine.
