Mr. EISENBERG. Could you circle a portion of the lines on 640 and mark it--I am sorry, that is 142. Mr. CADIGAN. I have marked it. Mr. EISENBERG. Mr. Dulles, would you care to look at it? Mr. DULLES. And--oh, yes--and they go over a good deal further than your circle? Mr. CADIGAN. Yes, sir. Mr. DULLES. They run right across. Mr. CADIGAN. I might explain that these are made by a wheel in the paper-tape dispenser. [Referring to an object in the room.] It is not quite this size, but it is similar to this and it has horizontal markings running all around the wheel. As you pull the operating handle that pulls the paper tape from the roll through the machine and over the wetting brush, the wheel, in the process leaves these markings on the tape. Mr. EISENBERG. Excuse me, Mr. Cadigan, would this be in the type of tape dispenser which is operated not merely by a handle--by a handpull--to the tape from the dispenser, but is operated--that is operated by a lever? Mr. CADIGAN. Yes; a lever, a handle. Mr. EISENBERG. And a given quantity of tape is dispensed, which you can cut off or not as you choose--if you want to, you can pull some more tape and cut it off, is that correct? 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. Mr. EISENBERG. Because it only gets the marks when you put it in the dispensing machine that you have in commercial establishments? Mr. CADIGAN. That is correct. Mr. EISENBERG. Would it be common to have this type of dispensing machine in a home, by the way? Mr. CADIGAN. I doubt very much that you would find it in a home. Mr. EISENBERG. Now, within a commercial establishment, are there more than one type of dispensing machines? Mr. CADIGAN. Oh, yes. Mr. EISENBERG. Are there types that won't produce these lines at all? Mr. CADIGAN. Yes. I might point out, too, that the number of lines per inch will vary depending on the diameter of that wheel. In this particular instance I found that there were 24-1/2 spaces, which would be 25 lines per inch, on both. Mr. EISENBERG. I believe that is 142, the bag you are handling, and 677, the sample? Mr. CADIGAN. Yes; the markings on the manila tape in both 142 and 677 were the same. Now, at that time I also had----
