History

• Existing Cutting Problem
• Bluestreak
• Problems
• Performs one cut at a time
• Damages spool
• Difficult to operate
• Unsafe

3
Design Specifications

• Simultaneous cuts
• Keep damage of spools to a minimum
• Minimize cycle time
• Address ergonomics and safety
• Solutions?

The Pneumatic Motion

• Key Features
• All motion is pneumatically controlled
• Pneumatic Cylinder is hinged vertically and
  horizontally
• Trough rests on pillow block bearings with
  linear guide rails
• Two cutting points with adjustability

Recommendations

• Precision machining should be performed on all
  frame and blade holder assemblies
• 1 inch steel guide rails and 1 inch cast iron
  pillow block bearings
• Directional air blowers
• Safety
• Lengthen frame and cylinder stroke to avoid
  pinch points and hands being close to the blades
• Blade guards
• Push buttons should be continuously pressed
  throughout entire operation

9
Alternative

• Change setup to a pulling orientation
• Decreases moment arm between the forward edge of
  the spool and the cylinder
• Change aluminum trough to steel

Closing Statements

• This team is confident that this design is an
  improvement over Eastmans current cutting
  capability.
• The overall design is much simpler and would be
  easier and cheaper to build. Its most notable
  improvement is that it makes the required two
  cuts that were especially lacking in the
  Bluestreak. Furthermore, this design is easier
  to operate, and could be much safer than the
  Bluestreak also.
• We believe that we have developed a good
  solution to Eastmans Bluestreak problem. And
  with some modifications, we believe this design
  to be a perfectly viable production tool for
  Eastman.

Thanks !!
The students of the Yarn Removal Team (Harold
Beever, Vickie Fortner, and Josh Landers) would
like to thank Eastman for this opportunity to
work in conjunction with a great company and
educational partner. This has been a great
experience for us all, and we hope Eastman keeps
supporting this program. The team would also
like to thank Dr. Donald Dareing for his careful
guidance and interest in providing us with an
outstanding learning experience.
