Wrapper Twisting/Gathering TRIZ Cases

Industrial vision and thermal imaging replace operator checks to detect sealing defects continuously on packaging webs.

A rotatable transverse sealing assembly uses fixed-axis guidance and dual-axis jaw movement to simplify maintenance in vertical form-fill machines.

A grounded conductive cover redirects heater leakage current, while insulating covers add layered protection against electrical shock.

A six-degree adjustment system aligns the sealing device for robust tube seals and faster package format changes.

During flow-wrapper acceleration and deceleration, cross-jaw path, time, temperature, and pressure adjustments maintain sealing quality for paper-rich film.

Induction-heated sealing jaws distribute heat across film seams and support rapid cooling, reducing material damage and clamping demands.

A T-shaped layout separates bag supply, filling, and removal modules, while a movable transfer device releases the filling module for maintenance.

Spring or pneumatic pre-loading offsets gripper weight during bag movement, reducing force demand, motor size, and displacement wear.

Chain-driven web conveying removes slippage in high-speed pouching, helping maintain pouch length and volume at up to 1,700 pouches per minute.

A sonotrode and zoned pressure plates localize ultrasonic melting and force at tube overlaps, limiting plastic lumps and energy use.

A polarized camera and image processing detect splices, wrinkles, and scratches before they disrupt package formation.

Preheating flexible sheets to 70–80°C activates adhesive before compression, enabling plaster packaging at up to 200 m/min with sealing integrity.

Separately controlled heating zones balance film plasticity during deep drawing, improving thickness uniformity, pouch stability, and print retention.

A T-shaped layout pulls the filling module from the bag-transfer line, improving maintenance access and product flexibility.
