Glue feeding and conditioning devices

OMMA glue feeding and conditioning devices ensure a stable, precise and uniform application of adhesives. Designed for perfect integration with OMMA glue spreaders, they maintain constant temperature and viscosity, thereby reducing material wastage and downtime. These devices adapt perfectly to production lines where accuracy, continuity and long-lasting performance are required.

Why choose a glue feeding and conditioning system?

First and foremost, opting for a glue feeding and conditioning system means ensuring reliable and optimized management of the consumables that form the basis of the gluing process. In addition to maintaining the technical parameters, these systems allow you to control consumption, automate refilling and make it safer to handle products that are often delicate. They also contribute to improving line efficiency by cutting down on manual work, stabilizing production rates and extending equipment life. For industrial enterprises seeking to standardize production quality while keeping costs under control, these devices are a fundamental tool in terms of performance and reliability.

Roles and goals of our glue feeding and conditioning devices

1. Mono-component glue feeding unit

• Role: Supplying the glue spreader with a continuous and constant flow of mono-component glue (ready-mixed adhesive).
• Goal: Ensuring that a seamless, uniform amount of glue is applied to the product, essential for bonding quality and productivity.

2. Automatic mixer for bi-component adhesives

• Role: Automatic blending of the two components of bi-component glue prior to application.
• Goal: Ensuring a homogeneous chemical reaction and effective bonding, with a constant pot life* and no changes in viscosity.

*Pot life is the time during which a bi-component adhesive remains usable after the components have been mixed

Note: Incorrect homogenization can lead to defective bonding or uneven hardening.

3. Preheating unit for PU glues

• Role: Warming up the components of PU adhesive (resin and hardener) to the optimal temperature before blending or application.
• Goal: Facilitating mixing, reducing viscosity to achieve a uniform flow and optimizing glue reactivity and bonding.

4. Glue cooling unit

• Role: Cooling the glue to a controlled temperature before it is applied to the product or stored.
• Goal: Maintaining the viscosity and stability of the adhesive, preventing premature hardening and ensuring precise dosing during application.

5. Melting unit (also known as Fusion unit)

The melting unit is an essential device in lines where a hot melt glue spreader is used. It can process classic hot melt glue, reactive PU adhesive and PSA (Pressure Sensitive Adhesive) adhesive.

For classic hot melt glue

• Role: Heating and melting solid adhesives (in blocks, granules or pellets) to make them fluid and injectable.
• Function: The molten adhesive is transferred by pumps to the applicator guns of the hot melt glue spreader before being evenly applied to the product by rollers.
• Goal: Ensuring a constant, homogeneous flow of adhesive for fast, precise bonding.

For reactive PU adhesive (bi-component)

• Role: Heating and maintaining the isocyanate component or pre-formulated PU adhesive at an optimal temperature for correct viscosity.
• Operation: Ensuring homogeneous mixing and even application before hardening.
• Goal: Guaranteeing gluing process repeatability, preventing clogging and ensuring controlled reactivity of the PU adhesive.

For PSA (Pressure Sensitive) adhesives

• Role: Gently heating certain solid or viscous PSA adhesives to facilitate their uniform application on the surface of the product.
• Function: Maintaining a suitable viscosity for product transfer without excess thickness or for formation of air bubbles.
• Goal: Ensuring immediate and uniform bonding, essential for self-adhesive products.
