Product Catalogue

Three RTS architectures.
Every level of automation covered.

inno-spin has specialised in automated material handling for decades. We offer Fixed-flow, Flexi-flow and Batch or Creel Flow systems, from entry level automation to efficient, traceable auto-creeling, each one proven in real Indian mills.

Fixed-flow RTS

A continuous overhead loop that is proven, economical and reliable.

A single continuously moving loop that links your Speed Frames and Ring Frames in a fixed sequence. Simple, compact and the lowest-cost system we make, and after more than 60 installations, our most widely deployed.

✓Manual-doffing Speed Frames
✓Mills making their first move from manual handling to automation
Not suited for
✕Auto-doffing Speed Frames on long or coarse-hank frames (see Flexi-flow)
✕Multi-count operations requiring frequent SF-to-RF remapping

Flexi-flow RTS

Train-based transport, the architecture that never blocks your Speed Frame.

Discrete bobbin trains that run from any Speed Frame to any Ring Frame, staged in parking until the creel is ready. A full empty train is always pre-parked before a doff, so auto-doffing frames keep running with no stoppages, and multi-count mills can remap production freely.

Best deploymentMulti-count, auto-doffing composite mills
Best suited for
✓Auto-doffing Speed Frames of any size or count
✓Multi-count operations requiring flexible SF-to-RF assignments
✓Mills running simultaneous production of different yarn counts
✓Large composite mills where machine stops must not propagate across the floor
Not suited for
✕Very small mills under 10,000 spindles where Fixed-flow offers better economics

Batch or Creel Flow

Auto-creeling on Flexi-flow infrastructure. Efficient and fully traceable.

Also known as auto-creeling. Built on Flexi-flow, it creels a whole batch of Ring Frames as one scheduled event instead of one frame at a time. It is not hands-free, but it is far more efficient and fully traceable, and it is about as far as creeling automation goes in an Indian mill today.

Technical summary
InfrastructureBuilt on Flexi-flow RTS
Also known asAuto-creeling
Creel modeBatch changeover, several Ring Frames at once
Operator involvementMinimal, and fully traceable
Count changeoverScheduled batch, one planned event
Best suited for
✓Mills already running Flexi-flow RTS looking to eliminate residual manual labour at the creel
✓High-volume composite mills with multiple simultaneous count changeovers
✓Mills targeting Industry 4.0 / smart factory integration
✓Operations where creel changeover time is a measurable production constraint
Not suited for
✕Mills without Flexi-flow infrastructure (Batch or Creel Flow runs on Flexi-flow rails)

System Components

The hardware behind every installation.

Bobbin Exchangers and Roving Strippers

Fitted on the speed frame, our exchangers swap full bobbins for empties hands-free at up to 180 per hour, and up to 300 on the high-speed version. The stripper cleans the empty bobbins before they return on the rail. We build the range in three configurations.

Twin Bobbin Exchanger with Adjustable Pitch

Two exchange heads set on an adjustable pitch, so a single machine matches different speed frame gauges.

Twin Bobbin Exchanger cum 2-Head Stripper

The twin exchanger with an integrated two-head stripper, cleaning the empty bobbins on the same cycle.

Standalone 4-Head Stripper

A dedicated four-head roving stripper that handles stripping as its own station, clearing four bobbins at a time.

Positively Driven Track Changers

Where a train changes route, a linear motor drives the rail segment to position and holds it there. A train is only released once the point reports it is locked. Learn more →

Parking & Storage Systems

Where full and empty trains wait between exchanges. We supply serpentine parking above the frame, a separate buffer bay, or both, sized to your floor. Learn more →

Overhead rail and open-profile track seen from above

Robust Overhead Rail Infrastructure

A modular aluminium rail profile engineered for Indian mill loads and ceiling heights, joined on site and carried on calculated structural loads with a safety margin. Learn more →

Beyond RTS

Automation across your entire mill floor.

inno-spin's engineering scope extends beyond roving transport. We offer automation across the full span of spinning mill material handling, from the spinning floor to finished cone dispatch. Get in touch to discuss your requirements.

Cone Transportation Systems

Cone Transportation Systems

Automated overhead and floor-level systems for transporting finished yarn cones from winding machines to packing and dispatch areas, taking the fork trucks out of the winding bay and reducing cone damage in transit. Engineered on the same overhead rail principles as our RTS product line. The system is optionally supplied with an integrated Yarn Conditioning Plant and pre-conditioning chamber, so cones pass through conditioning as part of the transport route rather than being handled separately on their way to packing.

Cone Packing Machines

Cone Packing Machines

Semi-automated and fully automated cone packing lines integrated with cone transport systems. Supports bag, carton and pallet packing, with consistent density, correct count segregation and automated labelling. Designed for the downstream end of ring spinning and winding operations.

Warehouse & Godown Management

Warehouse & Godown Management

Automated Storage and Retrieval Systems (ASRS) and AGV-based intralogistics for textile mill warehouses and godowns, covering finished goods, raw material staging and movement between floors in large spinning complexes.

Overhead Travelling Cleaners

Overhead Travelling Cleaners

Travelling cleaner units that run above the Ring Frames and Speed Frames, blowing and suctioning fluff away from the machines and the floor before it settles into the yarn path. Specified to suit your machine spacing, aisle widths and clear height, and supplied and commissioned alongside the rest of the installation so the overhead equipment does not conflict with your transport rails.
