Scanner Installation
Mechanical Installation of Scanner
At least one product scanner should be installed to detect the leading edge of the product. A single scanner can be
used to start the glue patterns of both channel 1 and channel 2 or the channels can have two separate scanners.
To install the scanner, follow these steps:
1. Position the scanner assembly brackets upstream from the glue station (Figures 12 and 13).
2. Set the scanner 1.5 to 2.0 inches (38mm to 51mm) above the product.
Note! The scanner must see through an open area on the parent machine with no obstructions.
Note! The distance between the scanner and the glue valve’s nozzle (cell-to-gun distance) cannot exceed the
distance from the leading edge of a product to the leading edge of the next product (repeat dimension).
The minimum distance allowed between the scanner and the glue valve will be greater at high parent
machine speed. The following is a general guide:
