LA 725 Pneumatic Applicators
These pneumatic bead and slot applicators provide contact or non-contact liquid adhesive dispensing in a variety of operations including corrugated, bag & sack and packaging applications. Whether continuous or intermittent production, the fast cycle times provide sharp, clean cutoff, particularly beneficial for dotting and stitching patterns. The repeatable, uniform dispensing helps optimize adhesive use while improving product quality.
Overview
- Achieve fast cycle times with advanced, high-speed solenoid technology.
- Realize faster maintenance and product changeovers from quick-change components.
- Reduce downtime and maintenance with robust design and construction.
- Dispense uniform, reliable patterns using snuff-back technology.

* Actual specification values will vary depending on adhesive type and application parameters
1 Cycle time will vary depending on adhesive pressure, viscosity and other characteristics
2 PH values outside the recommended range may result in corrosion or damage of seals, either of which will reduce the life and performance of the applicator. In case of unexpected corrosion due to adhesive used, the glue supplier needs to be contacted to identify an inhibitor that can be used as an additive to the glue to minimize corrosive effects.
Note: Adhesive used needs to be solvent-free
