Cutting the Ream Without Waste: A Guillotine Layout for Exercise Books That Recovers the Trim Strip as Usable Product
Year: 2026
Type: article
Abstract: This paper addresses a practical question in sheet utilisation: exercise books begin as large sheets that a guillotine reduces to blanks. Using a self-contained computation from stated assumptions, the study evaluates the options across the range a small operation ordinarily meets and identifies the point at which the balance of cost, quality and material use changes. The headline findings are that best blanks per sheet is 4; best orientation is portrait; waste pct best is 20; leftover strip area pct is 20; side strip width mm is 100; bottom strip height mm is 60. These figures come from a simulation study: the work is SIMULATED, NOT MEASURED, no physical trials were performed, and every number reported is taken from the deposited computation output so that any reader can reproduce or refute it with local values. The practical value of the result is a rule that can be applied at the point of work without further calculation, together with the tabulated cases from which the rule was derived and a statement of the assumptions on which it depends. Where the computation shows that a widely used practice wastes money or material, that finding is stated directly; where it shows that a popular economy is genuine, the size of the genuine saving is stated with equal directness, so that effort can be directed to the economies that are worth having.
