WF-10T Case Former Controls
5-33
The change-over procedure essentially involves exchanging the position of the ‘inner’ and ‘outer’
jawplates (when viewed in the un-rotated home position against the case magazine), and trading
the bell-crank type of pivot links (that determine the direction of rotation) with ones of an opposite
angle. The pivot links are connected to a common bar, which is actuated by a pneumatic cylinder
such that the pivot links rotate in unison.
Right-handed cases are erected by the cylinder extension stroke and left-handed cases are
erected by the cylinder retraction stroke such that part of the change-over procedure is to select
the appropriate controller logic for the cylinder home position and actuating direction. Since the
case proceeds on the machine centerline from the magazine through to the formed case
discharge, the balance of machine adjustments are unaffected by the direction of case erecting.
Figure 5-35: Right-handed Case Orientation
The WF-10T erecting a
right-handed case by
rotating the jawplates as the
case is drawn away from
the magazine in a counter-
clockwise direction (as seen
from above).
As the case blank is
separated from the
magazine, both side major
flaps of the case are
injected down into Pin &
Dome jawplates.
