Offline PowerSquare™ 224

A unique and innovative complete book making system for digital and offset print applications. It is available in three configurations to match your workflow: online, nearline or offline.

The Watkiss PowerSquare™ 224 is a unique and innovative complete book making system for digital and offset print applications.

To suit different workflows, it is available in three configurations: inline, nearline and offline.

In a single machine it combines the four processes of stitching, folding, spine forming and trimming to produce SquareBack™ books up to 224 pages thick. It features fully automatic settings for different book size and pagination, including variable stitch-leg length for varying book thickness.

The maximum book thickness, of 10.4mm (208 pages 80gsm, 224 pages 70gsm), is double that of alternative conventional booklet making machines, so it is ideally suited to higher paginations or to thicker stocks. This makes the Watkiss PowerSquare™ 224 a fast and cost effective alternative to perfect binding or tape binding. Digital print applications frequently use heavier stocks and need the flexibility to produce a wider range of finished books from a single process, with little or no operator intervention – the Watkiss PowerSquare is a perfect match.


A Single Solution

The PowerSquare is a single solution for books from 4 – ­224 pages. No other book making system offers this flexibility. It requires less capital outlay since one machine will finish virtually all production. It has the added advantage that printed sheets do not need any manual handling between different finishing devices.

  • Makes books from 4 – 224 pages

Consistent, Quality Stitching

The PowerSquare has a single stitch head which inserts one to six stitches in the spine of the book. The stitch head and clincher are static – the sheets move to the stitch, not vice versa. This means the stitch head and clincher never have to be moved, so alignment and stitch quality is consistently good.


PowerSquare Book Stacker

The PowerSquare Book Stacker (PBS) delivers huge efficiency gains by allowing the Watkiss PowerSquare to run, unattended, for extended periods.

The PBS stacks the finished books vertically which is extremely space efficient; and it requires very little additional floor space. With a capacity of 930mm, it can run for up to an hour without operator intervention. The stacker can be unloaded on-­the-­run and accommodates different sized books without adjustment to give uninterrupted production.

The PBS complements the PowerSquare’s capability for thick books and high volume production by streamlining the entire operation. The operator can set the machine running and simply walk away.


Space-saving, Ergonomic Design

The PowerSquare has a very small floor space requirement ­ significantly less than alternative book finishing methods. What’s more, when operating online to a printer, the finished books are delivered close to the normal operator position ­ not several metres ‘down the line’.


PowerSquare Two-­Knife Trimmer

The PowerSquare Two-­Knife Trimmer (P2T) is a compact module that completes the booklet making process by trimming the top and bottom edges of the book. It provides a professional solution for full-­bleed printed work, especially important for colour printed applications.

Fully automated from the PowerSquare’s user interface, up to 40mm can be trimmed from each end of the book, and the trim position can be offset to match the image position. All trimmings are transported outside the machine to a high capacity external waste box, allowing continuous operation.
