Vertical Seal Setup
The vertical sealing device must be positioned relative to the forming
tube before it can create vertical seals. Setting up the vertical sealing
device consists of moving it within striking distance of the forming
tube and centering the vertical sealing band on the desired sealing
location.
The stroke of the vertical engage/retract device is 20mm. In order for
the vertical sealing device to produce adequate sealing pressure, the
vertical sealing band must be 18mm away from the forming tube when
the vertical sealing device is in the retracted position.
The position of the vertical sealing device can be adjusted laterally to
accommodate different forming sets. When positioning the vertical
sealing device laterally, the vertical sealing band must be centered
over the silicon strip in the forming tube.
