When it comes to doctoring solutions, the common concept design of creping blade holders has always narrowed down the choices to just two main possibilities: rigid or flexible, both with their strengths and weaknesses. But what if a rigid doctoring system could boast the profiling advantages of a flexible one?
Oradoc, the renowed doctoring systems company, with thousands of installations worldwide, has come up with a groundbreaking doctoring solution that is bound to change the way papermakers have always thought about tissue creping.
That’s how OraLock™ was born: a brand-new, innovative doctoring system that deserves a unique place in the Yankee creping history. OraLock™ development took more than 3 years of R&D activities carried out by Oradoc engineers, including scale and full-size prototypes, off-line static tests and continuously running machine monitoring, to conceive, design and test this state-of-the-art creping solution, immediately protected with an international patent.
What makes OraLock™ a one-of-a-kind creping doctor blade holder are with no doubt its independent elements, which allow for an easier and quicker self-profiling procedure on the Yankee crown.
Thanks to the long-standing business relation with Sofidel, Oradoc had the chance to test the pilot installation of OraLock™ on the PM2 of their earlier ‘Delicarta’ plant in Lucca, a crescent former producing premium toilet paper. After more than one year, OraLock™ has proven to live up to expectations, confirming the great potential of this new rigid doctoring system, capable of offering a series of measurable advantages which confirm its ability to optimize the production process.
