- 10. A machine according to claim 9 having a separate signature feeder disposed at a point along the saddle conveyor spaced from the lap opener to deliver a second signature to the conveyor, timing means to time signature delivery so that the two signatures are gathered together on the conveyor one atop another, and means to stitch the gathered signatures.
- 11. A machine according to claim 10 having caliper means disposed between the lap opener and the trimmer to detect an imperfect signature due to the trailing end of an exhausted web spliced to the leading end of a fresh web, and means in advance of the trimmer to eject the imperfect signature.
- 12. A machine according to claim 9 having caliper means disposed between the lap opener and the trimmer to detect an imperfect signature due to the trailing end of an exhausted web spliced to the leading end of a fresh web, and means in advance of the trimmer to eject the imperfect signature.
