Double Edge Carrier Strip Width
Width to be added to the coil to accommodate a double edge carrier strip (see Press Carrier Strip Type). Select one of the following options:
Default: value of the cost model variable doubleEdgeCarrierStripWidth (16 mm in aPriori starting point VPEs).
User Override: enter a value greater than or equal to 0.
When you use double-edge type carrier strips with double-row nesting layouts, there are actually 3 strips: one at the top edge of the coil, one at the bottom edge of the coil, and one between the two rows of parts.  (So the total contribution to coil width is 3*double edge carrier strip width, or 48 mm by default in aPriori starting point VPEs).
(Note that no additional width is required for center-type carrier strips, since they are located in the middle of the row of nested blanks and are assumed never to extend beyond the blank edges.)
