Wrapping Paper Maker Converts Shafted Turret Winder into a Shaftless Turret Winder

One of the largest wrapping paper makers in the country sought the help of Double E regarding core extraction issues they were having on one of their production lines. This line was using a turret winder with strip shafts. The line was running a combination of 3" and 6" cores. The machine's operator had trouble handling the 55-60 lbs. shafts when the rewound roll was removed from the press. Roll changeovers were taking a long time. The customer's primary pain for this application was concern for operator safety.

Double E provided the customer with two 3" PC-4000 Pneumatic/Mechanical Core Chucks and two 3"-6" Step Idlers for the PC-4000. One pair of each was mounted on each arm of the turret winder. The PC-4000 was chosen because the application requires a positive grip chuck. The rewind stops and starts frequent¬ly. Because both 3" and 6" cores are run on this printing line, Double E also provided the customer with two 3"-6" adapters for the PC-4000 chucks.

The chucks were installed in mid-2007 and have been working well since. According to plant engineer at the production facility, "the chucks are working great and roll pro¬cess time has improved. All safety issues have been resolved." Now, the operator does not need to remove a 60 lb. shaft during changeovers. Double E and the customer have converted a shafted turret winder into a shaftless turret winder. This conversion resulted in a safer, more efficient work environment.
