Wrapper Folding/Bending Apparatus TRIZ Cases
- Automated Utensil Napkin Wrapping With Rolling and Adhesive Banding
A rolling wrapper automates utensil napkin wrapping with single-napkin feeding and adhesive banding to cut manual prep time.
- Progressive Folding Guides for Semi-Rigid Tubular Packaging
Discrete external guide surfaces fold paperboard and cartonboard progressively into tubes, avoiding bulging and creasing in HFFS packaging.
- Flap-Folding Conveyor Module With Pivoting Upstream Section
A pivoting upstream conveyor lets flap-folding sit close to rotation modules, using gas-jet edge lifting for reliable high-speed food wrapping.
- Wrap-Around Box Folding Unit for Precise Inner Flap Overlap
A mandrel-guided folding unit pre-folds the inner flap to secure precise overlap, reliable gluing, and jam-free box closure at high speed.
- Carton Blank Folding and Panel Alignment for Secure Article Packaging
Sequential folding and panel alignment automate carton formation around articles while reducing material use and improving transport stability.
- Wrap-Around Box Packaging Mandrel With Movable Blank Retention
A movable retaining device holds the blank against the mandrel during high-speed feeding to prevent misalignment and irregular box folding.
- Wrap-Around Box Closing Unit for Stable Blank Retention
A tilted hitting element lets the closing unit clear retaining devices, keeping the blank wrapped on the mandrel during fast folding and gluing.
- Folding And Heat-Sealing Assembly for Wrinkle-Free Multi-Material Packaging
A sliding folding plate and complementary sealing blocks hold elastic flaps in place for wrinkle-free, high-speed sealing across aluminum and polymer sheets.
