Glue application station 1907

This glue application unit combines the advantages of the glue system cartridge with the high availability of adhesive granules.

Design and mode of operation

A large stainless steel hopper serves as a reservoir for the hot melt glue pellets. At the lower end of the hopper, granulate can be dropped from the hopper into a rectangular cylinder by a pneumatic slide. Under high pressure, a piston forms a rectangular glue cartridge from the granules. The side of the cylinder opposite facing the piston is heated and perforated many times. There, the glue cartridge is melted at its front. Liquid glue passes through the heated channels and is applied to the workpiece edge by a glue nozzle using a transportation device.

Technical data

• Workpiece thickness 6 - 60 mm
• Capacity of the stainless steel hopper about 4 kg of granules
• Connection power about 4 kW - 4.5 kW
• Workpiece feed rate up to 20 m/min

Advantages

• Closed glue system, i.e. the glue is melted without air supply and therefore can not burn or loose its connecting and color properties by other oxidation processes.
• Only the required amount of adhesive is melted. This also reduces the cleaning effort at a color change.
• Short heating time of 3 - 5 minutes.
