Pneumatic bead gun combines zero-cavity needle and fast air-open/air-close actuation for high-viscosity cold adhesives used in high-pressure applications, including traymaking, beverage packing, and case and carton sealing.

• Minimize adhesive buildup and premature curing with zero-cavity needle.
  
  
• Control adhesive output with integrated needle-stroke adjustment.
  
  
• Prevent adhesive skinning over nozzle during dwell times with nozzle cover.
  
  
• Select from nozzle diameters ranging from 0.3 to 1.5 millimeters (0.012 to 0.059 in.).
