Cushion zipper continuous stock roll — identical openings scenarios.
How does changing identical openings affect cushion zipper continuous stock roll when the other inputs stay fixed?
What this decision changes
A known internal space, existing stock or shared quantity must enter the correct subtraction or eligibility step rather than being counted as new material. Method basis: Continuous zipper cut = supplied opening length + supplied total end extra; cuts must fit selected stock rolls. Does not choose zipper construction, sliders, stops or product compatibility.
The focus is identical openings in the first repeated measured entry. Other repeated entries keep their own supplied values.
Evaluate your supplied alternatives
Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only identical openings in the first repeated entry; the other entered values stay fixed.
6 evaluated scenarios
Baseline: Continuous zipper stock rolls — 2 rolls. Rejected combinations remain visible below.

|---|---|---|---|
| 1 | 1 roll | -1 roll | Open in calculatorExact quantity breakdown
Continuous cuts use decreasing-length first-fit packing. This is a feasible count, not a guarantee of the minimum. Any per-cut extra is explicitly reserved by you. Sliders and end stops are separate items. |

Continuous cuts use decreasing-length first-fit packing. This is a feasible count, not a guarantee of the minimum. Any per-cut extra is explicitly reserved by you. Sliders and end stops are separate items. |

Read the evaluated results
Watch the net requirement and actual order separately. Invalid rows identify combinations that cannot satisfy the method's geometric or stock-basis constraints.
- Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
- Enter a comparison range on the focused input's stated unit and quantity basis.
- Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.
- Open an evaluated scenario in the full calculator to save its original inputs and quantity breakdown to a browser material project.
Keep the comparison within scope
The supplied cavity, exclusion or stock eligibility must already be valid; the result does not select a safe shell, opening or construction detail.
Does not choose zipper construction, sliders, stops or product compatibility.
Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
