India's best known Commercial printer - Pragati Offset, Hyderabad has upgraded their bookbinding capability. They have made the initial step towards making thread-sewing redundant. From now on, most of the books made at Pragati - both hard cover and soft cover, will be bound using Polyurethene Reactive Hotmelts.

PUR has been chosen over standard hot melt adhesives for many reasons—with superior adhesion and layflat being the most important ones. There are other benefits too: high heat and cold resistance, less wrinkle on backbone, solvent resistance to name a few. In comparison to thread sewing a job first and then pasting a cover - PUR takes much less turn around time, at lower costs.

The major concerns in implementation of PUR were addressed - when Henkel International, worlds largest manufacturer of adhesives joined hands with Robatech AG of Switzerland and Welbound Worldwide, India.

The trio offered solutions for PUR across a wide ranging platform.

The PUR system at Pragati is a Robatech MOD4 installed on a Kolbus binding line. The adhesive is from Henkel and the integration of the system has been done by engineers from Welbound. According to M Suresh Nair of Welbound and the team leader for this project: Integrating a PUR system on an existing machine has its own challenges. What has helped us is our experience on spine preparation and gluing that are critical to perfect binding. The expertise of Robatech and Henkel came in as a great support. However the most critical factor behind this success is the customer's passion on delivering a unique experience to their client; and the patience they exhibited all through the installation process.

Jijesh Bhaskaran from Robatech India and Sandeep Pai from Henkel CAC Pvt Ltd were involved in the commissioning of the equipment and training the team at Pragati. P. Narendra of Pragati says : "The whole process of installation went off smoothly and I am thrilled that PUR is a reality in Pragati"
