In other embodiments, the catchers include drawbead inserts that facilitate conducting a drawbead friction test simultaneously with a tensile strip friction test.

A strain testing rig for testing an elongate specimen has at least three restraints arranged to be spaced apart along the elongate specimen. Each restraint engages the elongate specimen at a respective contact location such that the strain testing rig defines an independent strain zone between each pair of adjacent contact locations. A drive mechanism moves the at least three restraints to stretch each independent strain zone such that the length of each independent strain zone increases independent of strain in the other zones. The restraints can be pivotably connected end-to-end as a chain linkage. The drive mechanism drives the chain linkage from a first position in which a forward facing side of the chain linkage which opposes the specimen is substantially straight to a second position in which the forward facing side of the chain linkage is convexly curved.
