Heidelberg to Introduce a Host of New Products for Postpress at drupa
Both folders are operated from a console located on the feeder that features a clear layout and an ergonomic design for easy access. A graphic user interface guides operators step-by-step through the setup process, and an electronic self-learning mode offers additional support. Various monitoring functions that together ensure end-to-end quality control and greater production reliability, and that include a sheet travel monitor to check that all sheets comply with the specified length. A movable remote control for the 2nd and 3rd stations allows control of the folder downstream.
With up to three folding units and a maximum of 14 (Ti 52) and 16 (Ti 36) buckle plates, Heidelberg’s Stahlfolder Ti series folders produce a wide range of fold types, including complex fold-gluing and gatefolds. The 3.15x3.94˝ Stahlfolder Ti 36 specializes in the very short fold lengths with numerous parallel and cross-folds that are typical of items such as pharmaceutical inserts, user instructions, advertising materials, and packaging inserts.
The Stahlfolder Ti 52 fulfills the requirements of medium-format customers, such as quick and easy processing of traditional advertising brochures, flyers, and signatures with eight A4 or A5 pages. It can fold flat formats ranging from 3.94x5.91˝ to 20.47x 33.07˝. A host of configuration options enable both folding machines to be adapted for individual jobs.
On the high-output Stahlfolder TD94/112, an ingenious pneumatic twin lay system substantially increases output without increasing machine speed. Normally, the sheet is fed into the folding machine lengthwise, but with the new pneumatic twin lay system, it is rotated 90 degrees for oblong feeding.
The pneumatic twin lay system after the first folding station transports the sheets to a twin lay at the second folding station, where two sheets at a time are processed in parallel. As a result of the sheet's shorter feed length at the same machine speed, output is increased by around 30 to 40 percent based on format alone.
A Cutting Edge for One-Shift Operations
Connectable via ordinary house current wall outlet, the new programmable POLAR 56 guillotine cutter with hydraulic drive is an apt choice for commercial one-shift and digital printers. Equipped with a 5.5˝ monochrome (56 ECO) or 18.5˝ touchscreen display for the networkable version (56 NET), the small-format POLAR 56 combining POLAR’s legendary reliability, build quality, and ease of use in a new, small-format size will be launched at drupa 2012.
Digital Book Trimming
Digital book production down to run lengths of 1, combined with commercial print quality trimming at a reasonable cost has been a challenge in the industry. Choices for trimming have been either expensive book trimmers, or cutting on standard guillotine cutters. The latter raises quality issues due to the clamp crushing the spine, unless a special clamp is used.
