Text: 28 (A) a roll rotatably supported on said frame, means for rotating said roll, means for feeding a web onto said roll for travel therewith while in partial wrapping engagement with said roll, 29 (B) said frame also being equipped with a plurality of mandrels, means for moving said mandrels sequentially through a path in close proximity to the surface of said roll        . (Patent Reissue No. 28,353, Column 12, lines 23-31.) 30 This is best understood by viewing Figure 1 of the patent in suit (Appendix A-1) where the frame is designated 37, the roll (termed a bedroll in the specification) is numbered 36, and the means for rotating the roll is a motor 45 and associated gearing (not shown in Figure 1 in Appendix A-1). The means for feeding the web consists of the tension control mechanism 30, rolls 31, 32, pull rolls 33, and rolls 34, 35. The mandrels are designated 39 and are mounted on a turret 38 which constitutes the means for moving the mandrels. 31 13. The improvement characterizing part reads: 32 (B)    the improvement comprising: 33 (C) means for transversely severing said web for approaching a mandrel on which said web is to be wound in said path, (and) 34 (D) pin means extensibly mounted on said roll for maintaining a web portion spaced from said edge in contact with said roll, and pusher means extensibly mounted on said roll to urge said maintained web portion against an adjacent mandrel. (Patent Reissue No. 28,353, Column 12, lines 31-41.) 35 These elements can be best seen in Figure 21 (Appendix A-6). The transversely severing means includes a knife mechanism 51 which further includes knives 58 and 59 mounted on the bedroll 36 and a cooperating knife 64 provided on the cooperating chopper roll 49 (seen best in Figure 4 in Appendix A-4). The pin means which maintain a web portion in contact with the bedroll are designated 56, while the pusher means includes the pads 55, all cooperating to overcome the 1,000 feet per minute speed limitation. 36 14. The operation of the cutoff and transfer mechanism of the machine of the patent can be seen in sequence in Figures 20, 21, and 23 (Appendix A-6 and A-7). Figure 20 represents the condition of the elements when normal winding is occurring-the web W traveling with the bedroll 36 and being wound on a retail size roll 50. Figure 21 shows the condition of the bedroll 36 and chopper roll 49 near the end of a winding cycle, while Figure 23 (also Figure 4 in Appendix A-4) shows the condition of these two elements at the beginning of a subsequent winding cycle. When the bedroll 36 is travelling at 2,000 feet per minute surface speed, the Figure 23 showing is about 0.03 seconds later than the showing in Figure 21. The web W in Figure 21 is seen in the process of being severed by a knife mechanism generally designated 51 so as to provide a leading edge 52 to engage the core 53 mounted on a mandrel 54 in the next winding station. In Figure 23 the edge 52 is seen in contact with the core 53 under the urging of a pad 55. 37 15. The result of this arrangement is that it is possible to utilize about 270o of one revolution of the bedroll 36 to operate the cutoff and transfer mechanism-it being seen in Figure 23 (Appendix A-7) that the extension of the knife mechanism 51 does not interfere with the winding of the web W on the new mandrel 54. In contrast to this, the prior art mechanisms had to achieve cutoff and transfer in a very small angular distance following the mandrel 54, i.e., the arc occupied by both the prior art knife and pusher. A secondary advantage of the invention is its ability to wind two-ply or multi-ply tissues as seen in Figure 5 (Appendix A-4). There the parts are in the same operative condition as seen in Figure 4 (Appendix A-4), but are seen operating against a web generally designated W and made up of webs W' and W. The web W is seen to be trapped within the reverse fold 52a (Figures 22 and 23 in Appendix A-7) provided by the leading edge 52 as it is urged against the core 53 of the new mandrel 54.
