Floor-model Folders -- Accessories Add Sparkle
Zero-makeready buckle plates are a popular feature on folding machines, according to Brigitte Cutshall, postpress marketing representative at Heidelberg USA. The sheet stop can be adjusted via a knob control and be used as a swing deflector. She notes there is no need to remove the buckle plate and position the swing deflector, as is the case with a standard buckle plate, which generally requires two sets of hands due to its weight on larger folders.
Delivery systems are often overlooked as well, Cutshall comments, as the full benefits of faster, automatic folding equipment cannot be realized if the system does not keep pace. Heidelberg has enjoyed success with its Vertical Stack Delivery, VSA.D.
“The function for this unit includes counting of single sheets and batching, marking by lateral shifting and double pressing of a single sheet,” says Cutshall. “It can deliver as many as four-up. We also have the upright stack delivery, SBP.D, with the same functions of the VSA except that folded pieces are delivered upright, on the edge of the fold.”
With a general lack of qualified operators in the U.S. market, Cutshall believes customers are seeking more automated and less labor-intensive equipment. In response, Heidelberg offers the 20˝ Stahl TD52 and 30˝ TD78 folders.
The 52 has standard features such as flat pile feeder with TREMAT, fully automatic buckle plates, automatic slide lay guide on cross carrier and DCT 2000 comfort control. The 78 has the same basic standard features, along with a continuous round feeder.
Pressing and/or stacking deliveries continue to be popular options for printers and trade binders, according to John Porter, division manager for LDR International. In-line gluing, he adds, is still highly desirable.
“The ability to finish small books on the folding machine can be very cost-effective,” Porter states. “Manufacturing of return envelopes is only one of the many different products that can be done in-line on the folder with the modern glue systems.”
