The Drum or cylinder in the belt feeder should clear the belt by about 6 inches.
If there is too much clearance between the drum or cylinder and the belt it does not
bite into the cotton and will not feed the cotton into the tramper hopper properly.
With about 6 inches of clearance the belt feeder gets a good bite on the cotton and
will put the cotton under the tramper foot properly.
The drum should only rotate from 1 ½ revolutions to 1 ¾ revolutions on each stroke
of the tramper. This will put all of the cotton you need under the tramper foot on each
stroke.
The belt feeder must stop promptly. If it continues to roll it will feed some cotton as
the tramper foot goes down.
This results in a bat of cotton that reaches from the bottom of the tramper foot when it
is at the bottom of the stroke, all the way up to the belt feeder.
This bat of cotton keeps the press dogs on that side of the press from coming in and
catching the bale under the tramper foot.
The bale will then bellow up on that side of the press and when you go to turn the
press the cotton will stick up above the press boxes and prevent the press from
turning.
The mechanical brake on the belt feeder motor does not last very long and when it
wears out the above happens.
There are electrical brakes that apply DC power to the windings of the motor that will
always stop the belt feeder properly, which is what the belt feeder needs.
Hydraulic motors are also available to drive the belt feeder and are better that the
electric motors.
