If your press dogs do not hold in the last few strokes as the bale is finished the
cotton pushes up past the press dogs. The cotton sticking above the box drags on
anything above the press boxes and keeps the press from turning correctly. The
press does not go far enough to lock in and you have to pull out all of the gin stands
while the press crew gets the press locked and ginning can continue.
The bale when pressed usually has a rainbow and the strapping machine has
trouble strapping the bale. In door-less press the enormous sidewise force
sometimes breaks the top ram.
When the tramper foot pushes the cotton into the press box past the dogs the dogs
are pushed completely out of the press box and gravity is supposed to bring the
press dogs back into the box where the dogs will catch the cotton and prevent it from
bellowing out the top of the press box. Trash build-up and wear around the press
dogs and the shaft they ride on increases the friction and keeps the dogs from
operating properly.
If you will restrict the dogs so that the tip or end of the dogs stay inside the press box
by about 1 inch when the tramper foot goes back up the cotton will catch this 1 inch of
dog sticking in the press box and the cotton will always pull the dogs back into the
press box.
To restrict the dogs so that they will stay inside the press box about 1 inch you need
to weld a plate on the outside of the press box under each dog so that the dogs
cannot be pushed out of the press box by the cotton the tramper foot is pushing into
the press box.
On an up-packing press the dogs are mounted so that when the follow block comes
up the dogs are rotated out of the press box. They are above the bar that you weld on
and it does not interfere with this action of the press.
On a down packing press the follow block just goes by the 1 inch of dog sticking into
the press.
