System 1900 - Automatic string beading of 1 component adhesives & resins

System 1900 automatic 1K adhesive application system for bonding sandwich panels, the adhesive is extruded out PTFE nozzles which are fitted in a line in the steel spreader, the 'strings' or 'beads' of glue are spread across the panel in an uniform patterm. Low to medium viscosity one-component adhesives, such as moisture cured Polyurethane’s, PVC, PVA, MS-Polymers and Silicates are suitable for System 1900.

This automatic spreader for glue is suitable for such applications as door, sandwich panel or Structural Insulated Panel production where an even and accurate adhesive spread is required, and can be supplied with fixed spreader bars over a conveyor line or a moving spreader over a bed (lay-up table).

In the fixed design, the panels are transported on a conveyor under the spreaders. In the movable design, the spreader bars move over the panels applying the adhesive. In the Moving Spreader Bar design the bed acts as a lay up table as the spreader bar moves over the panel applying adhesive. A combination of both types of system 1900 can be utilised, machine configuration will depend on panel type and size(s) as well as production speed, press times and existing process's.

The spreader can be split into sections manually or automatically for variable panel width and can also be equipped to automatically control the amount of adhesive and water applied to the surface in gram/m2. The automatic PLC control system activates the stop and start process of the adhesive to eliminate waste. The operator needs only to push the start button to activate the system, making automatic gluing a much smother process.

The system is suitable for manufacturing a wide variety of products using surface materials such as steel, aluminium, wood, GRP, gypsum etc., and core materials like rock wool, polystyrene, Styrofoam, PIR etc.
