Wrapper Twisting/Gathering TRIZ Cases

Segmented driving assemblies synchronize film tube and re-closable strip speeds, preventing slippage and creases caused by differing material tensions.

Curved cutting edges reduce force and eliminate wear by maintaining distance from the sonotrode during ultrasonic sealing.

Continuous motion wrapping system eliminates reciprocating shock and vibration while compressing products tightly.

Rolling cylindrical elements replace sliding contacts in packaging machines, reducing wear and improving seal strength.

Reconfigurable flap guides and synchronized gluing enable successful carton closure during conveyor stoppages by applying adhesive before cooling.

Heating only the external surface of a sealing strip reduces energy consumption and cooling time while maintaining seam integrity.

Replacing thermal current with mechanical friction welding improves sealing precision and packaging speed.

Multiple sealing bars seal film tubes on retractable conveyors to maintain continuous product motion.

Independent motion of heat-sealing elements eliminates reciprocating stops, resolving mechanical stress and enabling continuous high-speed packaging.

Metallic side edges conduct heat through a coating that prevents material sticking, extending operational life and reducing replacement frequency.

A crank shaft clipping tool assembly drives closing tools via sinusoidal paths through guide slots.

Distributed bus node assemblies relocate electronics outside work stations to improve maintenance access while protecting components from contamination.

A sensor detects bag mouth position between horn and anvil pressing surfaces to control ultrasonic vibration activation.

A compact bundling device uses a rotating transport system to cyclically apply adhesive and join beverage containers into packs.

Vertical device placement reduces planar footprint and simplifies cleaning.

A servo motor drives lateral sealing while detecting article arrival via torque signals.

A sealed adjuster aligns packaging structures via a manually operable portion while maintaining strict hygiene through integrated sealing arrangements.

An automatic packaging machine rotates and stacks paper bags for efficient adhesive sealing.

Dual servo motors and a counterbalance reduce mechanical vibration during high-speed sealing.
