Convertech Ltd

The directors' of Convertech Ltd. and it's sister company W M Stevenson Ltd. have been involved in machinery and equipment used by the printing, converting and other allied industries over a span of 30 years and has witnessed and survived many changes by keeping faith with its customers'  and adopting, pro-actively, methods required to address commercial trends and introduction of new and improved technologies.

Anticipating these changes Convertech have, over the years, invested heavily in developing practical, cost effective machinery. In more recent years we have concentrated on developing a range of web sheeters which also provides a wide choice of options for building simple or complex systems, including  facilities for incorporating other technologies and end of line equipment i.e. stacking, conveying, packaging etc.

We are conscious of manufacturers' problems regarding tight margins and try our utmost to help the situation by keeping our own overheads to a minimum and by networking with associates and partners in the UK and abroad. This enables Convertech to offer comprehensive solutions at affordable prices without reduction of quality or standards.

Cropping Knife

Highly Suited For Incorporating Into Various Production Line Applications.
 

Cropping Knife

Typical Applications

Convertech have developed various guillotine type systems suitable for a wide range of sheeting, cutting and cropping applications. These can be integrated into dedicated new systems or retrofitted to existing plant.

Application: The following example is of a fully automated system designed and built by Convertech for removing stapled splines from books, then presenting batches of resulting sheets to digital scanners for reading collected printed data.

Method: The stapled books are pre-loaded into two magazines and then auto fed singly onto a conveyor which presents the spline to the knife area which is then accurately clamped and cropped preventing knife damage by the metal staples but also assuring the printed area is not affected or mutilated. Crumple sensors’ are positioned to prevent pre-damaged or misshaped books entering the knife zone. Cropped sheets are then stacked and fed in batches to the scanners.

Typical Applications

Heavy Duty Sheeter
