shall be free from right and left rattling, permitting smooth
movement up and down.

can be raised by both hands
when installing the roller pressure ad-
justing screw

and there is too much
pressure, this will be a cause of cutting
off the chain-off thread.
3. If the clearance is too much between the
upper feed roller
1
and the throat plate
2
, this will be a cause of failure in sup-
plying the chain-off thread.
4. If pressure of the upper feed roller
1
is
too weak for the material cloth, uneven
feeding may arise.
