This book traces the cascade from corrugator to retail shelf and explains why variation, not the average, decides line performance, and why a box that passes BCT in the laboratory can still pop open in the field.\n\nThe argument follows a clinical arc. Anatomy describes the four corrugator-side defects, washboarding, warp, striping, and crushing that the folder-gluer cannot recover. Pathology shows how they converge at the Manufacturer's Joint, where peel and cleavage replace shear as the failure mode, and PVAc holds the joint at five to fifteen per cent of final strength against the full spring-back force. Diagnosis distinguishes symptom, mechanism, and upstream cause; the framework for the secondary fracture; the adhesive defect catalogue; and the variation analysis at the crease.\n\nTreatment introduces two interventions. Waterscoring reduces spring-back by a factor of three to four through local, transient plasticisation of the crease line; the same mechanism prevents the print-side white-crack defect on digitally printed corrugated. Damage Tolerance Design,  borrowed from aviation, replaces the continuous adhesive bead with redundant, segmented patterns that arrest crack propagation; PTS test report 35.756 documents +75 per cent Factory Edge Strength at 30 per cent adhesive consumption.\n\nThe synthesis closes with PPWR Compliance: less material requires more precision, and only the integrated combination of waterscoring, damage-tolerant bonding, adhesive monitoring and process discipline satisfies the regulation and the field-failure metric. A field guide for production engineers, quality managers, plant managers, sustainability officers and packaging strategists from corrugator to retail shelf.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783696378028\"\u003e\u003ch3\u003eDiagnosing Variation, Treating the Cause - A Field Guide to the Manufacturer's Joint from Corrugator to Retail Shelf\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783696378028","offer_id":58201549144389,"sku":"9783696378028","price":22.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ddefa9b4-1654-4cce-9264-e8f40cf79e24.jpg?v=1781071387","url":"https:\/\/shop.autorenwelt.de\/products\/that-bond-that-matters-von-thomas-walther","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
