Wrapper Twisting/Gathering TRIZ Cases

Independent infrared radiation sources heat plastic parts along joint contours without physical contact to enable precise temperature control.

Eccentric rotary systems drive sealing heads along combined trajectories to join filter bags.

Rotating suction means hold the wrapper sealing portion at a pick-up region for automated transport to an application head.

Cruciform cutting member prevents lateral separation of the resilient support, ensuring consistent seal quality and extending edge life.

Movable operative groups on linear guides dynamically adjust positions to optimize sealing pressure distribution while maintaining high production velocity.

Segmented receiving elements enable precise positioning and counter pressure application for hermetic sealing despite obstructive tube geometry.

Pivoting heating element melts plastic layers to form adjustable seals, replacing rigid containers that occupy excessive cabinet space.

Individual heating bodies with separate temperature sensors control each sealing station, resolving inconsistencies in packaging quality.

Segmented flaps use pre-applied adhesive layers to create compressed triangular tabs, resolving sealing complexity in industrial open-point packaging.

Convex curved unfolding guide surfaces prevent wrinkles on package sheets, enabling shorter printing-to-sealing distances and reducing material waste.

A thermoforming packaging machine uses impulse sealing bars to seal cavities with top film.

A box packing apparatus holds cardboard boxes with long sides downward to transfer overlapping articles in rows along the length.

Inclined sealing surfaces push product particles away from the sealing band during induction heating to ensure clean polymer fusion.

An electronic counter tracks ultrasonic sealing cycles via capacitive voltage division, resolving monitoring difficulties during equipment transfers.
