Now you can have 100% inspection of hot melt adhesive to your product . . . not only its
presence, but its position as well. Employing new state-of-the-art infrared techniques
(patent pending), the SnakeEye provides photocell simplicity of operation, with
extraordinary thermal sensitivity to "see" each and every bead as it is applied
in real time.
The SnakeEye Thermal Switch is installed immediately downstream of the hot melt
applicator, and provides 2 on/off photocell type of switches as it sees the thermal
presence of the leading and trailing edges of adhesive. Sensitivity level is adjustable.

Width of Bead
The minimum bead width at a given line speed is specified in the chart below. Simply
estimate bead width and confirm that maximum and minimum line speeds fall within
"Recommended Applications" area.
Length of Bead
The minimum bead length at a given line speed is specified in the chart below. Simply
measure bead length and confirm that maximum and minimum line speeds fall within
"Recommended Applications" area.
