Wrapper Folding/Bending Apparatus TRIZ Cases

A rolling wrapper automates utensil napkin wrapping with single-napkin feeding and adhesive banding to cut manual prep time.

Discrete external guide surfaces fold paperboard and cartonboard progressively into tubes, avoiding bulging and creasing in HFFS packaging.

A pivoting upstream conveyor lets flap-folding sit close to rotation modules, using gas-jet edge lifting for reliable high-speed food wrapping.

A mandrel-guided folding unit pre-folds the inner flap to secure precise overlap, reliable gluing, and jam-free box closure at high speed.

Sequential folding and panel alignment automate carton formation around articles while reducing material use and improving transport stability.

A movable retaining device holds the blank against the mandrel during high-speed feeding to prevent misalignment and irregular box folding.

A tilted hitting element lets the closing unit clear retaining devices, keeping the blank wrapped on the mandrel during fast folding and gluing.

A sliding folding plate and complementary sealing blocks hold elastic flaps in place for wrinkle-free, high-speed sealing across aluminum and polymer sheets.

A gas jet lifts the sheet edge and an edge catch folds it over food products at high speed without disturbing product position.

A carousel-supported fixed frame removes bulky ground supports, expands working space, and keeps packaging units close to the rotation axis.

Sequential end-panel folding and side-panel positioning automate carton formation around moving articles while reducing waste and maintaining secure containment.

A slit-guided loop-forming tool simplifies ribbon reversal and insertion to create consistent decorative bows with less knot-tying skill.

A controller adjusts carrier spacing to each carton size, cutting manual changeover time and downtime in mixed-batch cartoning.

Lifting the cover sheet’s side portions while a pressor stays engaged supports continuous film wrapping and stable pallet loads.

Pre-marked hinges and angle references simplify diagonal folds, while a knot-tying tool helps create neat ribbon knots with less skill.

This case combines adhesive application and folding to package paper rolls without major changes to existing machinery.

Rotating forming and drawing wheels create cavities before item insertion, reducing handling stress while supporting continuous sealing.

Rotating shuttle elements create twisted ends, reducing product handling damage and simplifying machinery complexity.

Paired grips hold bag mouths during intermittent movement, preventing inclined seals caused by bag instability in paper packaging machines.

A pivoting mandrel forms and fills bag-in-box packages in a single continuous cycle.

A rotating platform moves palletized loads to a fixed wrapping head, eliminating complex vertical movement mechanisms and reducing device assembly costs.

Replacing complex vacuum systems, a rotating brush station uses frictional contact to fold and tighten packaging edges, eliminating pneumatic maintenance.

Stack support portions incline coins while an inclination maintaining portion holds their angle during vertical stacking.

A crowder assembly maintains item arrangement while a machine folds and secures custom box templates around the stack.

A rotating disc mechanism folds cardboard case flaps with precision, eliminating frequent manual adjustments required by traditional pneumatic actuators.

Real-time detection of physical properties enables dynamic acceleration adjustments that prevent item displacement while maintaining high throughput.

Airflow generator and suction device remove dust from filter bag packaging paths, preventing contamination without interrupting production.

Articulated pressing elements connect to non-coaxial drive disks for horizontal tool plate alignment during container application.

Multi-station folding machines adapt to varying bag dimensions while maintaining continuous packaging throughput.

A packaging apparatus adjusts film holding tension to stabilize articles during discharge.

A moving integrated unit combines filling, gusset forming, and sealing actions to eliminate sequential delays and reduce production defects.

Clamping grips prevent elastic return and wrinkling of thin packaging sheets during hopper transfer.

Perpendicular wrapping stations calculate dimensions to cut materials, reducing waste while adapting to varying item sizes.

Distinct sealing zones on the proximal and distal flange parts prevent accidental unfolding while minimizing heat exposure to the confectionery product.

A rotating head integrates grasping and sealing mechanisms to synchronize film wrapping operations during continuous rotation.

Integrated rotating elements in conveyor modules correct package orientation without separate transfer units, reducing system complexity.

Adjustable support frame rails and vertical erecting lugs enable continuous in-line packaging of varying article configurations without stopping the process.

Rotating arms fold and glue stiff package flaps to adjust squaring, reducing system length while maintaining precision.

Suction pressure adheres the film to the vehicle surface, eliminating manual squeegee labor.

Longitudinal movement of the divisible folding channel reduces transfer complexity and increases throughput in high-speed packaging.

A petal mandrel shapes laminar sheets into a pleated cup, eliminating air pockets and ensuring a tight seal around irregular products.

Automated folding machine uses a rotating plate and gripping tool to fold sterilization packaging materials.

Radial grippers eliminate misalignment from fixed buffer friction during W-shaped folding.

Double welders secure film sections on stack sides and tops, preventing slippage during transport before shrinking.

A height-adjustable guide frame pivots to center wrapping webs on crop bales.

A pneumatic securing mechanism holds windowed envelopes flat on a deck while a deflection element guides collation materials away from the window edges.

A retaining sheet wraps around stacked comestible products to maintain upright organization within a package interior.

Segmented foldable side panels and self-fastening mechanisms stabilize object fixation during transport while simplifying manufacturing.
