How thinking differently led to a new era of tissue rewinding

Paragon’s radically new, yet comfortably familiar, design combines the best of both center and surface rewinding

Every successful building project requires a good foundation. From the tallest skyscraper to the smallest house, quality construction demands a secure footing and sure support.  We all know it’s important. We won’t settle for less. The same principle holds true when constructing a roll of toilet paper or paper towel.

After decades of designing and building high-performance surface rewinders, Paper Converting Machine Company (PCMC) began asking some thought-provoking questions about support. What if the logs did not have to climb uphill to get into the winding nest? What if large-diameter logs did not head downhill late in the wind cycle, but instead had consistent support from beginning to end? What if the logs did not have to scale up and over the summit of a curved surface at all?  What might a superior foundation bring to rewinding?

The answer is Paragon, PCMC’s new high-speed tissue rewinder.

Paragon employs a revolutionary new winding nest with a winding belt beneath the product, as well as a winding drum, a compound-motion rider roll, and driven core chucks (center drives). The incoming logs arrive on the belt at the side of the winding nest, progress smoothly along the nearly horizontal surface of the belt and roll off the far end of the belt when winding is complete.

The belt platform affords exceptional control and support for the logs from start to finish of the winding, as well as superb caliper retention of the wound web. Paragon sets new standards in ease of use and productivity and redefines the pinnacle winding quality.

Winding drum and winding belt:

  • The incoming log decelerates under greater control in the space between the winding drum and the winding belt, arriving in the winding nest smoothly and reliably.
  • The winding belt is a nearly horizontal platform, providing unmatched support for all diameter logs from start to finish of the winding cycle. Continuous movement and fewer velocity changes eliminate the need for numerous operator adjustments.
  • The winding belt minimizes nip pressure at the bottom of the log by having a larger contact area. This preserves caliper in the wound web and is especially important with today’s lightweight webs and large diameter products.

Center drives:

  • The center drives control core rotation within the log, providing another element of winding control while also preventing vibration in the core ends.
  • Low inertia components and precise servo motion control allow the center drives to precisely track the centers of the winding logs and operate fluidly at even the highest speeds and cycle rates.
  • The center drive chucks utilize elastomer rings that expand radially when compressed axially and contract rapidly prior to withdrawal of the chucks.This results in precise timing and minimal wear. There are no inflatable air bladders to wear out and leak.

Compound-motion rider roll:

  • The compound-motion rider roll is positioned for optimal control both during winding and at the log discharge.
  • Paragon utilizes a closed transfer glue extrusion system and has exceptional open access at both the front and rear for operators and maintenance.

PCMC’s history in tissue converting dates back nearly a century. Paragon combines leading technology from PCMC’s proven Forte rewinder with an innovative, patent-pending winding design. Paragon initiates the dawn of not just another century, but also a new era of rewinding.  Imagine the possibilities.
