Wrapper Folding/Bending Apparatus TRIZ Cases

Vacuum mechanisms hold sheet media against conforming belts, preventing bruising during automated produce wrapping.

Segmenting long cardboard into two blanks resolves the trade-off between material usage and manipulability, enabling efficient packing of large-format tiles.

A rewinder distributor attaches protective sheets to web material rolls using a gripping roller mechanism.

A label carrier positions a central portion while presser elements fold end portions onto lateral sides.

Flexible sheet forms tubular body matching capsule shape to reduce packaging material volume and inert gas consumption.

Mobile sealing stations extend thermal contact duration to resolve the contradiction between production speed and seal quality in high-speed packaging.

A bottleneck operation adheres sheet material to convex products, resolving air retention issues in irregular surface packaging.

An oscillating swinging platform wraps plastic film around wide coil side faces, reducing material consumption and preventing breakage.

Automated carrier transition eliminates manual repositioning steps, reducing loading time for wrapping material rolls.

Adjustable fold lines on base and cover sheets enable stepless height variation, minimizing internal gaps for improved transportation efficiency.

Pivoting arms with clamps tension belts directly, eliminating belt frame insertion errors and friction wear on low stiffness materials.

Segmented folding lugs press carton blanks onto grouped articles to resolve precision complexity trade-offs in high-throughput packaging.

A shuttle change system uses a movable carrier to align parallel track sections for film roll replacement.

Anti-interference spacing means prevent the round baler web feeder from contacting motion means protrusions, eliminating bending damage and operational noise.

Dual actuators rotate and spread folding fingers to automate carton formation while reducing design complexity.

Segmented vertical walls with radial openings enable user-defined delivery directions while minimizing base plate distortion and operating noise.

Alternating flap folding rigidifies panels to bypass false score weaknesses and prevent panel collapse during box formation.

Tilting the circular guide reduces machine width, allowing full assembly within standard ISO shipping containers.

Oscillating grippers position confectionery products on a stationary wrapping surface for high-speed operation.

A spring-loaded rake eliminates cotton bunching during plastic wrap application, preventing hydraulic stalls and damaged film.

Inverting gripper holding to base and end portions allows a brush unit to uniformly smooth wrapping sheets without lateral surface interference.

Rod-shaped folding fingers move independently to adapt packaging mechanisms to varying carton dimensions.

An integrated head unit merges band transfer and fastening functions into a single apparatus, reducing initial investment costs and improving space utilization.

Servomotors replace springs to control sealing jaw torque, reducing dwell time while ensuring reliable bag seals.
