Wohlenberg Lucro: Simplifying Automation in Boook Binding

19 Dec 2012

Wohlenberg'sLucro is the answer to need of book printers in countries like India, to have a robust and beneficial solution for high speed book production. The proven German technology is adapted to include features that will sustain the stress of not-so-ideal working conditions: be it the quality of substrate, the operator know-how, electrical stability and so on. And to do this, with a justifiable investment, has been the key brief given by Dr Michael Euler, the managing director of Wohlenberg to his technical team.

Lucro combines the strength of the proven efficiency of the Sprinter gatherer and the City binder, with sensible and essential automation, that is foolproof. The Sprinter is a high speed automated gatherer that can run at speeds upto 8000 books per hour, offline. It uses the patented Winjector (R) technology that is quicker, more efficient and energy saving. The direct shaft-drive of the gatherer, without chains, ensures zero transmission loss of motion. The gathering and transportation of signatures is vertical, thereby avoiding additional elements for straightening prior to entry into the binder : again an example of saving on space and energy.

The optional PUR spine gluing nozzle QuickJet with integrated pre-melter ensures an exact application of the glue due to its ideal arrangement of the gear pump and nozzle head.

The Lucro binder is a 5000 books per hour work horse. The centralised clamp adjustment with indicators for thickness, makes change overs simple and cost effective at the same time. Multiple milling stations are provided, with a powerful dust extractor. Wohlenberg's well known, patented, gluing stations with integrated premelters come as standard with the Lucro. These are on casters and can be removed and replaced with PUR, as needed. The special rotary cover feeders handle standard covers as well as gate-folds with equal elan. The cover feeder also operates with the Winjector(R) technology, thereby negating the need of additional vacuum pumps.The cover scoring tools are adjustable on the fly and there are specialised tools to address the common problem of cover separating from the book-block, with the first page. The downhill delivery is compact and efficient.

The perfect binding line is central to the workflow of soft cover book production. Lucro delivers the unique advantages offered by other Wholenberg lines - be it in handling difficult signatures, loose leaves, gate-fold covers etc.

WohlenbergLucro follows the lineage of the Wohlenberg binders that stand out for their smart and economic use of space and energy. For a 5000 books per hour machine, Lucro requires the lowest foot print and consumes the minimum of energy.

The standard Lucro is offered as with a 12 station Sprinter gatherer and 15 clamp Lucro binder with a vertical stack delivery. There is also the option of adding a conveyor and a Trim-tec45i, inline trimmer.

Lucro is a product designed and developed by Wohlenberg, the leading manufacturer of softcover adhesive binding lines. The technology for manufacturing of the same is being transferred to Welbound, who will assemble the machine in their Thiruvananthapuram plant. The transfer of technology, up to the component level will happen over a period of time step, by step. According to A V Chandrasekhar, the Director with Welbound Worldwide who will manage the knowledge transfer, the Wohlenberg designs are focused to derive highest efficiency in every moving part. They go to prove that 'simplicity is the highest level of sophistication'
