Convert pfaff 335 cylinder walking foot to rolling feed

[michalm]

Hi, I own a shoe repair shop in Canada and I’d like to convert my pfaff 335 walking foot cylinder arm into a rolling feed ( something like a seiko Te series ). Ive seen it done with singer walking foot into a rolling foot attstchment. Was wondering if anyone knows exactly which rollers would work. Thank you !!

To my best knowledge this only works on machines with permanent wheel feed or oscillating feed dog (feed dog that goes up and down and back and forth) but not on "binding" machines that have a feed dog that only goes back and forth (not oscillating) as the Pfaff 335 or Adler 69.
