INNOVATIONS & INVESTMENTS<br />

Kolbus launches KM200 perfect<br />

binder at DigiMedia exhibition<br />

KOLBUS USED the DigiMedia<br />

exhibition to launch the<br />

KM200, a perfect binder for<br />

digital <strong>print</strong> applications.<br />

This is a fully automated<br />

perfect binder using the<br />

technology that Kolbus uses for<br />

its high volume machines, but<br />

including automated set up<br />

systems to cope with varying<br />

thicknesses of product.<br />

“Provided the format is not<br />

changed, every product can be<br />

different,” says Kolbus UK<br />

managing director Robert<br />

Flather. “<strong>The</strong> machine offers<br />

zero makeready, adjusting<br />

automatically to the different<br />

product sizes.”<br />

As configured at the<br />

exhibition, a gathered book<br />

block is measured for width<br />

before feeding into binder. <strong>The</strong><br />

Thinking of moving to processless plates?<br />

Aurora plates deliver high reliability and performance<br />

<strong>The</strong> Kolbus KM200 is a perfect<br />

binder for digital <strong>print</strong> applications.<br />

Kolbus swinging arm clamps<br />

are designed to approach the<br />

block on a parallel path to lock<br />

the book into position and<br />

coping with thicknesses from 5-<br />

60mm. Once clamped a more<br />

precise measurement of book<br />

thickness is taken, details of<br />

which are used to set the cover<br />

feeder and side glue nozzle<br />

position. <strong>The</strong>re is no need to<br />

adjust spine preparation or the<br />

spine glueing section because<br />

this uses an open tank system<br />

rather than nozzle applicators.<br />

All adjustable elements are<br />

based around movements<br />

outwards from a centre line<br />

position, calculated from<br />

measuring the clamped book.<br />

Thus the scoring wheels for the<br />

cover are moved away from the<br />

centre line into a precise<br />

position to suit that book. Each<br />

subsequent book can have a<br />

different thickness. Cameras<br />

can be used to ensure that<br />

covers match the body of the<br />

book before feeding.<br />

After the cover is in place,<br />

the pressing unit will also selfadjust<br />

around the centre line of<br />

the book. <strong>The</strong> speed of the<br />

binder will be dependent on<br />

the number of different sizes<br />

handled. Without adjustments,<br />

the line will run at some<br />

5,000cph.<br />

“Until now people have had<br />

to live with four clamp binders<br />

which becomes a struggle with<br />

higher volumes,” says Flather.<br />

“This is book binding that<br />

delivers a quality product.”<br />

By Drupa next year Kolbus<br />

will have linked the binding<br />

unit to upstream systems,<br />

either directly to gathering<br />

lines, to digital presses or via<br />

technology to create book<br />

blocks from webfed digital<br />

<strong>print</strong>.
