Eliminate fibre cracking on your stitching machine

On stitched work, the spine is the product. Magazines, brochures and booklets get judged on that one fold, and it is the first thing a customer picks at: white cracked lines along the staples, straight through solid colour, coated stock and digital print.

The cause sits at one point in your machine. As the cover travels through, it passes over a single metal score in a set position, one steel profile crushing a line into the sheet on its way to the fold. It cuts the fibres it should be stretching, and the fold breaks along the damage, copy after copy.

This is the score doing the damage, and what replaces it:

The Spine-Creaser takes the metal score's place and puts a pressed, cylinder-quality crease exactly on the fold line, inline, at full machine speed. Depending on your machine it uses a rubber creasing matrix that wraps the drum, or a creasing band running against a channel, both the same patented principle that has eliminated fibre cracking on folding machines for twenty-five years.

Spine-Creasers are built per machine, for stitchers, saddle-stitchers and cover feeders alike, and installation typically takes under thirty minutes. The spine comes off the machine clean on copy one and copy one hundred thousand, and the fold your customer judges the job by stops being the fold you apologise for.
