Mr. Cadigan. That is correct.
Mr. Eisenberg. And this wheel, as I understand it, when you pull the lever this wheel forces the paper out?
Mr. Cadigan. It turns, and it is really pulling the paper from the roll and pushing it out from the slot.
Mr. Eisenberg. That has a slight knurl which grasps the paper?
Mr. Cadigan. It has a slight ridge all around it which is the cause of these marks on the paper tape.
Mr. Eisenberg. Okay.
Mr. Dulles. Is that a defect in the mark or a peculiar——
Mr. Cadigan. Oh, no; it is designed that way. Those little, you might say, in effect, teeth, go into the paper and pull it through smoothly.
Mr. Eisenberg. If I went into Woolworths and bought a roll of gummed tape, would it have those marks on it?
Mr. Cadigan. No.
