Note
For short segment tests, use a portion of the sample that has not been tested: the end of the fabric sample not used in the long segment test.
To position the fabric:
-
Open both clamps.
-
Lay the sample on the clamps and across the block, aligning one short edge of the sample on the edge of the fixed clamp.
-
Pull up the screw head on each clamp and tighten it.
-
Lightly roll up the loose end so it is positioned on the movable clamp and does not touch the base plate.
The following image is a side view of how the fabric should be positioned.
1: Base plate. 2: Fixed clamp. 3: Narrow block. 4: Movable clamp. 5: Fabric sample.
-
Ensure the fabric is straight (centered between the clamps) and flat, but not stretched.
-
Check that the needle on the force indicator is in the center. For example:
Note
Do not over-tighten the clamps, as this affects how the material performs.
