The presser foot cylinder works only during the
straight sew of the panel. When the machine is
ruffling the air pressure is turned off to this
cylinder and the foot pressure is just the spring
pressure from the spring located inside the sewing
head. The spring pressure is set with as little
spring pressure as possible.
The panel tension works by pinching the panel
between it and the top plate. This is adjusted based
on the type of panel being sewn, 15 psi is normal.
If the panel gathers then there may be too little
tension on it, if the border gathers then there may
be too much tension on it.
