Saddle Stitchers — A Staple of Fine Finishing
McCain offers a range of machines, from the 13,000 per hour S2000 to the McCain Tandem catalog machine, which produces at a rate of 24,000 an hour. The S2000 produces products from 3x6˝ to 11.75x19˝ with face cuts as large as 2.5˝. It boasts new makeready features including a new operator control module, downstream shutoff and sequential startup.
Every manufacturer has its own performance claims, states Bob Morton, president of Best Graphics, thus printers need to be on the lookout for productivity-enhancing features that enable them to make a more informed purchasing decision. He encourages shoppers to take notes at major industry trade shows.
As Seen at Trade Shows
"When we demo our stitchers at Graph Expo and other trade shows, you'll typically see Best Osako cover feeders running bond paper at 10,000 sheets per hour," he says. "This is possible because, after scoring, Best Osako stitchers register the cover with a pull side guide, fold the cover stock with a crimp fold mechanism and, finally, fold the cover after scoring. This folding-after-scoring capability enables printers to run very lightweight stocks at high speeds, eliminating the need to prefold stock and run it through a rotary feeder."
Morton notes that Best Osako stitchers employ unique tilt back/tilt forward design rotary feeders that pivot to either side of the rail, which provides a major advantage.
"Whenever signatures are weighted differently on each side—trifolds, response cards, envelopes, etc.—they will not drop vertically to the rail due to the imbalance," he says. "The feeder 'tilt' capability, coupled with the added vacuum power and consistency of individual feeder pumps, allows signatures to be easily positioned to drop squarely in place, making easy work of difficult signatures."
Heading the Best Osako line of stitchers is the 13,000 per hour 368AS AutoSet, with touchscreen control over key operations, set stitch head positioning and chain timing in only 15 seconds. The product line also includes the entry-level Estar and the 368AS HiLo Folio for maximum production.
