Jiayuan is a specialized manufacturer of hot melt coating, laminating and extrusion equipment. We develop customized production lines for adhesive tapes, labels, medical materials, nonwoven fabrics, textiles, industrial laminates and other roll-to-roll products.
Our hot melt coating laminating machines combine adhesive melting, precision metering, web coating, material lamination, cooling and rewinding in one continuous process. Depending on the finished product, the line can be configured for single-sided coating, double-sided coating, slot-die coating, fiber spray coating or multi-layer lamination.
From compact machines for product trials to wide-web, high-speed production lines, Jiayuan matches each system to the customer’s adhesive, substrate and production target.
Different products require different adhesive application methods and web-handling configurations. Jiayuan supplies hot melt adhesive coating machines for the following production requirements:
Designed for double-sided tape, cloth tape, foam tape, masking materials, self-adhesive labels and other pressure-sensitive products.
The line can be equipped with precise adhesive metering, stable tension control and continuous winding systems to support uniform coating and efficient roll production.
Suitable for medical tape, wound dressing materials, plaster products, breathable nonwoven laminates and other medical consumables.
Fiber spray or controlled low-weight coating can be selected where the finished material needs to retain softness, flexibility or air permeability.
Used to bond fabrics, nonwovens, films, foams and synthetic leather for garment materials, footwear, filtration products and automotive interiors.
The coating and laminating sections can be adjusted according to material stretch, surface sensitivity and the required bonding structure.
Developed for automotive floor materials, waterproofing products, industrial fabrics and other wide roll materials.
These production lines can incorporate heavy-duty unwinding, web guiding, tension control, cooling and high-capacity rewinding according to the width and weight of the substrate.
Smaller hot melt coating machines are available for laboratory trials, new product development and limited production runs.
They allow manufacturers to evaluate adhesives, coating weights and material combinations without occupying a full-scale production line.
The coating method has a direct effect on adhesive coverage, coat weight, breathability, bonding performance and finished-product feel.
Melted adhesive is accurately metered and delivered through a heated slot die onto the moving substrate.
Slot die coating is suitable for continuous, uniform adhesive layers and applications requiring controlled coating width and coat weight. It is commonly selected for adhesive tapes, labels, films and other roll materials.
The hot melt adhesive is distributed in a fine fiber pattern rather than as a completely closed layer.
This creates an open coating structure that can reduce adhesive consumption and retain greater softness or breathability. It is often used for nonwoven fabrics, medical materials, filter media, textiles and other flexible substrates.
For products requiring adhesive on both surfaces, the machine can be configured to complete double-sided coating within a continuous production process.
This reduces repeated material handling and is particularly suitable for double-sided adhesive tapes and multi-layer self-adhesive products.
The adhesive is applied to one substrate before a second material is introduced through the laminating section.
Controlled pressure and web tension help join the materials into a stable composite structure. This process is suitable for fabric-to-film, nonwoven-to-film, foam-to-fabric and other multi-material laminates.
A complete hot melt coating and laminating line can include several coordinated processing modules:
Unwinding: Feeds one or more substrate rolls into the line.
Web guiding: Corrects material position to maintain accurate edge alignment.
Tension control: Stabilizes the web during acceleration, coating and rewinding.
Preheating: Prepares selected substrates before adhesive application when required.
Adhesive melting and metering: Melts and delivers hot melt adhesive at a controlled temperature and flow rate.
Coating section: Applies the adhesive by slot die, spray or another selected process.
Laminating section: Combines the coated substrate with a second material under controlled pressure.
Cooling section: Stabilizes the adhesive and laminated structure before winding.
Rewinding: Produces finished rolls with controlled tension and alignment.
Optional modules can include turret unwinding and rewinding, roll accumulators, additional laminating stations, edge trimming, inline slitting, protective film feeding and automatic roll-changing systems.
Jiayuan hot melt coating machines can be configured according to the viscosity, processing temperature and application behavior of the selected adhesive.
Common adhesive options include:
Pressure-sensitive hot melt adhesives
EVA hot melt adhesives
PUR reactive hot melt adhesives
Thermoplastic adhesive formulations
Application-specific hot melt compounds
Typical roll materials include:
Paper and release paper
PET, PE, PP and other films
Nonwoven fabrics
Woven and knitted textiles
Foam materials
Filter media
Synthetic leather
Aluminum foil
Medical and hygiene substrates
Waterproofing and industrial sheet materials
Because different adhesives and substrates behave differently under heat, tension and pressure, material testing is recommended before the final machine configuration is confirmed.
Produce double-sided tape, cloth-backed tape, foam tape, medical tape and other pressure-sensitive adhesive materials.
Apply controlled adhesive layers to paper or film for labels, stickers and advertising consumables.
Manufacture breathable medical tapes, dressing laminates, plasters and other flexible skin-contact products.
Laminate fabric, film, foam, leather and nonwoven materials for garments, shoes and functional textiles.
Bond decorative surfaces, foam, textile and sound-damping layers for interior trim and floor materials.
Create multi-layer filter media, technical nonwovens and other functional industrial laminates.
Configure coating or extrusion lines for self-adhesive waterproof membranes and related construction materials.
Jiayuan does not recommend a machine solely according to coating width or production speed. The complete process should be evaluated before the production line is designed.
Important project information includes:
Finished product and layer structure
Substrate type, thickness and width
Adhesive type and operating viscosity
Required coating weight
Full coating, pattern coating or fiber spray
Single-sided or double-sided application
Required production speed
Maximum unwind and rewind diameter
Manual or automatic roll changing
Available factory space and line layout
Required downstream slitting or cutting process
Based on this information, the coating head, glue supply system, winding structure, tension-control zones and optional modules can be selected for the project.
A modular machine structure allows individual processing sections to be selected or upgraded according to changing production requirements.
A production line may begin with a basic coating and rewinding configuration and later add a second unwind station, laminating unit, spray system, accumulator, automatic turret rewinder or inline slitting module.
Jiayuan can also adjust the coating width, operating speed, adhesive application system, heating capacity, winding arrangement and control interface according to the customer’s materials and factory conditions.
Send us your substrate samples, adhesive information, finished-product structure, target coating weight, required width and production speed.
Our engineering team will review the coating and laminating process and recommend a suitable hot melt coating machine configuration for product trials or continuous production.
