Custom PRIMO Continuous-Feed Process Systems

PRIMO Continuous Fabric, Yarn & Web Coating Systems

Custom heated immersion and dip-coating equipment for continuously processing fabric, yarn, thread, cord, paper, film, nonwovens, and other compatible flexible substrates through waxes and temperature-controlled coatings.

Each system is built around the substrate width, coating material, temperature, immersion path, line speed, coating-control method, cooling distance, and take-up requirements.

Continuous Immersion Process

The flexible material travels through the heated bath, around the immersion roller, and into a cooling, drying, wiping, squeezing, or take-up stage. The exit equipment can be positioned away from the bath so the substrate has the required open run before it is wound.

Modular melting capacity

Keep the Coating Bath Small & Add Wax Capacity as You Grow

PRIMO continuous fabric-coating systems are designed to minimize the amount of standing wax in the coating bath. The coating station holds the active working volume, while one or more separate PRIMO wax melters can maintain reserve wax and replenish the bath as needed during production.

As your production needs grow, you can add another standard PRIMO wax melter to increase reserve and replenishment capacity—without replacing the fabric coating machine or rebuilding the material-handling line.

  • Less wax tied up in the active coating bath
  • Reserve melted wax available for replenishment
  • Add melting capacity as production increases
  • Keep the original coating and material-handling system

Flexible-substrate applications

Configured Around What Moves Through the Bath

Working width, strand count, absorbency, tension, coating pickup, and cooling behavior determine the system.

Fabric & Continuous Web

For textiles, cloth, nonwovens, paper, compatible films, tapes, and other roll-fed materials.

  • Custom usable working width
  • Full or controlled partial immersion
  • Optional wiping, squeeze, or metering stage

Yarn, Thread & Cord

For one or multiple continuous strands requiring guided travel through a temperature-controlled coating bath.

  • Single- or multi-strand guide arrangements
  • Adjustable spacing and immersion path
  • Manual or powered winding

Coating & Impregnation

For surface coating or deeper penetration using waxes and other reviewed, compatible process materials.

  • Temperature and viscosity control
  • Residence-time and line-speed review
  • Cooling, drying, or setting after immersion

Correct equipment classification

Continuous Coating Is the Primary Process

The defining function is the continuous movement of fabric, yarn, thread, cord, film, paper, or another flexible substrate through the heated coating bath and downstream handling stages.

A circulation pump may be added to support temperature uniformity, filtration, or coating consistency, but circulation does not define the machine. It remains a continuous immersion or roll-to-roll coating system.

Primary process
The flexible substrate moves continuously through the coating bath.
Optional supporting process
The coating material circulates through a pump, filter, return, or conditioning loop.
Downstream process
Excess coating is controlled and the substrate cools, dries, sets, or advances to take-up.

Application data

What WaxMelters Reviews Before Quoting

Continuous coating performance cannot be selected by tank capacity alone. The web path, coating behavior, roll handling, and downstream cooling or drying requirement must be reviewed together.

RequirementWhy It MattersWhat to Provide
SubstrateDetermines roller surfaces, guidance, tension, and compatibility.Material type, thickness, absorbency, flexibility, and whether it is fabric, web, or individual strands.
Working widthDetermines bath length, roller face, frame width, heat input, and coating inventory.Maximum coated width, edge clearance, strand count, and strand spacing.
Coating materialDetermines temperature range, wetted components, circulation, and cleaning method.Material name, safety data sheet, heated viscosity, normal temperature, and maximum temperature.
Coating resultDetermines immersion path and whether wiping, squeezing, or metering is required.Target pickup, coating thickness, penetration, finish, or acceptable process range.
Line movementDetermines residence time, drive sizing, roller arrangement, and production output.Target feet or meters per minute, desired immersion time, and pounds or yards processed per shift.
Roll handlingDetermines unwind, take-up, shaft, brake, motor, and structural requirements.Maximum roll diameter, roll weight, core size, winding direction, and tension needs.
Cooling or dryingDetermines the required open run and whether fans or another process stage are needed.Available floor length, expected setting time, target exit condition, and ambient limitations.
FacilityDetermines electrical, controls, frame, guarding, sanitation, and installation details.Voltage, phase, frequency, floor-space limits, washdown method, ventilation, and area classification.

Frequently asked questions

Continuous Coating System FAQs

Is this a roll-to-roll coating machine?

It can be configured as a roll-to-roll system when the substrate feeds from a roll and winds onto a take-up roll. The same heated immersion platform may also process individual yarns, threads, cords, or other continuously fed flexible materials.

What is the difference between a continuous coating system and a circulating dip tank?

In a continuous coating system, the substrate moves through the coating bath. In a circulating tank, the coating material moves through a pump or process loop. A continuous system may include circulation, but the material-handling path remains its defining function.

Can the take-up station be placed farther from the heated bath?

Yes. The outfeed and take-up arrangement may be separate and movable so the substrate has the required cooling, drying, or setting distance before winding. Available floor space and the desired exit condition are reviewed during configuration.

Can the system begin with manual winding and be powered later?

Manual, geared, and variable-speed powered take-up arrangements are available. When future automation is planned, WaxMelters can review the initial frame, shaft, and drive provisions so the system has a practical upgrade path.

How much coating material must be held in the bath?

The bath is designed around the required working width, roller diameter, immersion depth, and operating level. This keeps the coating inventory matched to the process.

Can the system process coatings other than wax?

Potentially. Material compatibility, heated viscosity, operating temperature, safety data, cleaning method, and facility classification must be reviewed. Solvent-based, reactive, combustible, or otherwise hazardous materials require specific engineering review and may not be suitable for a standard configuration.
