Piercing Arrangements TRIZ Cases

Priority rules give avoidance and parking top rank and manual service orders high rank, cutting maintenance delays on textile machines.

Selective low-speed control of independently driven drafting rollers prevents sliver denting and stabilizes yarn uniformity during air-jet spinning piecing.

Counter-rotating cylinders tear yarn tails inside the splice path, improving control for stretch yarns while keeping the splicer compact.

Sequential bottom and upper air jets detach and lift broken fine yarn from the cop while reducing air use and yarn damage.

Selective linking of spinning and thread-drawing vacuum lines enables flexible vacuum allocation, workstation adaptation, and lower resource use.

Status checks at each spinning station help the service carriage skip irreparable thread breaks, cutting downtime and preserving capacity.

Independent output roller control combs the fiber strip end while upstream rollers pause, improving vortex spinning restart and reducing thread defects.

An air-suction yarn nozzle maintains tension and positions auxiliary yarn for reliable piecing on empty or full spindle tubes.

Nonlinear acceleration of the drafting rollers and take-off device moderates fiber feed, improving thread bonding during piecing.

Negative-pressure suction holds the broken yarn tail while horizontal and traverse positioning aligns it with drafted fibres for accurate over-piecing.

A textile-machine control unit adapts yarn piecing steps to yarn characteristics, balancing success rates with spinning efficiency.

This spinning case uses reduced-speed roller pairs and suction airflow to align fiber sliver while avoiding drafting-unit downtime.

A suction nozzle extracts thread ends from a bobbin while an eyelet guides the material through an extraction port to form a loop.

Automated detection and self-service repair of yarn breakages reduces production losses while managing system complexity through integrated control functions.

A gripper arm and tensioning arm guide yarn tangentially to the ring for insertion into a rotating traveler.

Dividing glass fiber bundles into strands creates smaller spliced knots, preventing resin impregnation defects and production stoppages.

A service robot uses vertical linear guides and an endless belt to move handling means along a ring spinning machine row.

An injection channel generates reverse airflow to guide yarn ends through the fiber guiding channel in air-jet spinning machines.

A yarn end discharge unit separates and removes thread sections between the spinning outlet and winding device.

A yarn handling device uses compressed fluid to switch between suction capture and pinching grip for precise thread control.

Twist applying nozzle generates whirling airflow via compressed air injection to apply twists to weak yarn ends, reducing breakage and air consumption.

A textile handling unit captures and transfers sliver between workstations using integrated detection sensors.

A synthetic yarn splicer uses dynamic clamping forces to pull yarn ends before entangling them into a uniform joint.

Vertically spaced pins form an oblique yarn section that allows compressed air to guide the traveller, reducing tension and preventing bounce.

Segmented suction elements detect and grasp sliver ends across multiple stations, resolving reliability issues caused by imprecise positioning.

A splicer nozzle divides the yarn hole into two displaced chambers to entangle fibers with compressed air.

Movable hooks adjust position based on yarn tension to prevent damage while maintaining automated joining efficiency.

Independent dual chambers sequence air pressure to fix strand alignment, restoring tensile strength lost in single-chamber designs.

An integrated thread guide on a pressure roller unit separates yarn segments to prevent oscillation and entanglement in textile machines.

A reset actuator arm positioned at the front of a drafting frame enables manual resetting of a roving detent element.

Suction holding portion replaces mechanical grippers to prevent yarn damage while maintaining precise positioning accuracy.

A textile machine service unit employs a camera system to determine work station positions, eliminating complex sensor networks and reducing device costs.

Jet members supply air currents to lift broken yarn ends toward drafting zones, resolving manual labor bottlenecks in ring spinning.

A spinning machine control unit classifies positions by production parameters to optimize piecing sequences.

A yarn removal detecting section confirms spun yarn separation from the hooking member in air-jet spinning units.

A piecing device selects between thread end search and auxiliary thread attachment based on workload.

A textile machine divides service operations into independent sub-sequences to execute partial tasks when energy resources are available.

A spinning auxiliary thread take-up adjusts its speed offset to manage thread loop dimensions during piecing operations.

A rotatable thread deflection device with a fixed ejection point regulates spindle tension.
