. A ?rst pressing pressure means in the form of a power
diaphragm 34 of conventional type is mounted within the

36 is forced upwardly to bear against and move a lever
47, which is mounted on the pivot P. It is understood
that at this time, the carriage 15 and buck 11 will be in
the pressing position. That is to say, the buck 11 will
be in position directly beneath the pressing head 33. At
this time, a plunger 46 attached to the bottom of the buck
11 is then in position to be engaged by the lever 47 when
said lever 47 is moved upwardly by the plunger 36. The
buck 11 is mounted by any conventional means on the
carriage 15 so as to be slidable upwardly and down
wardly. Thus, when the plunger 36 lifts the lever 47
upwardly, the lever 47 bears against the end of th plunger
46, lifting the buck upwardly in the cabinet against the
pressing head 33. In this manner, a pressing operation is
performed on a collar dressed on the buck.
