Description of flexing samples

Single flex (A)
The material is broken at 90° to the running direction.
Tool to be used: flex knife and non-grooved flex bars.

Double flex (B)
The material is broken at +40° and -40° to the running direction.
Tool to be used: spiral flex bars.

L-flex (C)
The material is broken in the running direction.
Tool to be used: round grooved flex bars.

Combiflex, trible flex (C)
The material is broken in the running direction and at +40° and -40° to the
running direction.
Tool to be used: round grooved flex bars and spiral flex bars.

Combiflex, quadruple flex (E)
The material is broken in the running direction; at +40°/-40° to the running direction
and at 90° to the running direction.
Tool to be used: flex knife, round grooved flex bars, spiral flex bars and
non-grooved flex bars.

Configuration possibilities

The configuration possibilities showed are examples. There are various flex bar configurations possible.

Example 1
Layout: 6 flex bars of the same type (e.g. type 30536).

Example 2
Layout: 1x non-grooved flex bar at inlet, followed by 2×2 spiral flex bars (e.g. type 47235) as well as 1x non-grooved flex bar at outlet.

Example 3
Layout: 1x round grooved flex bar at inlet (e.g. type 3036), followed by 2×2 spiral flex bars (e.g. type 47235) as well as 1x non-grooved flex bar at outlet.
