I'm having problems feeding these to the pick and place. As the tape peels off the pocket the part sticks to the tape rather than remaining in the pocket. Machine is QUAD QSV. We've tried all generations of feeders we have available. Any advice is

You are correct, the Hover Davis label feeder works on 'un-punched' flat carrier. Get a sample of your dots on the tape and send it to Hover Davis to see if their feeder will work for you. The Hover Davis feeder will peel the dot off of the tape so
