The 135P-16106-NOTCHED roller is specifically for the front product drive roller on the Dispensa-Matic Flex+Matic label applicator. This version has a notch cut into the center of the roller so that the photo eye sensor can detect the presence of a bag, and begin dispensing/applying the label.
If you need the rear label drive roller for your Flex+Matic machine, order part 135P-16106
This part is not compatible with the Bottle-Matic, nor is it equivalent to a modified roller. This roller is specifically a replacement for the front product drive roller on a Flex+Matic.
