260 Pages are no Problem for the Three-Knife Trimmer of the Primera PRO

Gofin in Gorzów invested in a Primera PRO not least because the Polish publishing company stitches numerous voluminous magazines and the variable-thickness three-knife trimmer of the new Muller Martini saddle stitcher is predestined for this.
Founded in 1989 under the name Zakład Doradztwa i Organizacji and renamed Gofin Tax Publishing House eleven years later, the graphic arts company runs a production plant with 176 employees, including prepress, printing, saddle stitching, perfect binding and sales. On the other hand, it has a publishing house that issues numerous specialized publications in the tax, accounting, insurance and labor law segments for companies, institutions and individuals throughout Poland and, in some cases, abroad.
"Our wide range of publications – magazines, gazettes, books, Internet services, multimedia programs – is primarily aimed at accountants and human resources and payroll services," says Marek Siwkowski, production manager at Gofin. "For the various publications, we have in-house editorial teams with proven experts. These can react quickly to legal changes, keeping our readers up to date."
High demands on the three-knife trimmer
The magazine with the most subscribers is a 76-page newsletter for business and financial services, published every ten days in a 170 x 240 format and with a circulation of around 20,000 copies. Gofin prints its own products – which include books and the twice-weekly newspaper "Gazeta Podatkowa" – itself and thus has full control over all stages of production. A large proportion of these are wire-stitched – with a total annual circulation of around 4.5 million copies.
The fact that this includes magazines with a volume of 228 to 260 pages naturally places high demands on the saddle stitcher – and especially on the three-knife trimmer. That's why at the beginning of this year, in addition to its two Heidelberg ST 100 and ST 350 saddle stitchers, Gofin also commissioned a 14,000 cycles per hour Primera PRO from Muller Martini with cover feeder, six vertical pile feeders, two flat pile feeders and Perfetto compensating stacker. "We not only need a modern machine with a high number of cycles and motion control drive for fast and precise setup, but also – most importantly for us – an automated and thickness-variable three-knife trimmer that does not require the operator to make any manual adjustments," emphasizes Marek Siwkowski.
Eliminating human error
"The use of modern machines and the automation of production processes promote efficient work on the one hand and largely exclude human error on the other. With the Primera PRO, the operator's main task is to enter the data correctly in the convenient touchscreen. The automated processes that follow shorten the entire production cycle." Here, the Primera PRO usually runs a single shift from Monday to Friday, but can also run a second or even third shift if necessary. "After all, flexibility and the ability to react quickly to changes are a must in our industry."
Marek Siwkowski leaves no room for doubt: "There is no comparable saddle stitcher in this performance class on the market. Together with our innovative strength, the Primera PRO will certainly have a positive impact on our market opportunities."
