Principle of Operation:
Each Chute is independently operated, however, they work
together to guide the new coil end into the flattener
or shearwelder.
1. After the new coil is loaded on the uncoiler and/or
rotated into the line-run position, the hold down rolls
are indexed against the top and bottom O.D. of the coil.
2. Using the feed up drive of the uncoiler (or optional
feed up drive) the coil is rotated in the direction of
line travel, feeding the strip into the speed funnel.
3. Each chute is then indexed back off the uncoiler slightly
and then indexed together, thereby "sandwiching" the new
coil between the chutes. This "sandwich" effect reduces
most of the coil set, and allows easy threading of the
new coil.
4. The operator continues to jog the uncoiler, causing
the strip to jog forward into the flattener or shearwelder.
5. Once threaded, the Speed Funnel is reset, which opens
the chutes and returns them to the home position.
Note: With a Speed Funnel system, it is not necessary
to use a traditional peeler blade to break the back of
the coil. This greatly reduces the coil thread time.
