Section 2.2: Wedge Adjustment
Wedge Pressure or Depth Adjustment
Wedge Pressure is the amount of force that the Wedge is applying to both the top and
bottom panel at the contact point pressing the fabric against the Weld Rollers. Adequate
pressure of the Wedge will allow just enough heat to transfer into the material in order to
produce a quality seam. Insufficient Wedge pressure will not allow enough quality contact
if not enough heat to transfer into the fabric or film which will produce inefficient welding
speeds as well as undesirable weld quality. While too much pressure will produce tracking
problems and trouble keeping the material in the Weld Rollers and Guides. Check the
Wedge Pressure by welding a test strip to be certain that the Wedge is contacting the fabric
with the proper amount of pressure pushing the material against the Weld Rollers
producing a quality seam. Should the Wedge Pressure need to be adjusted proceed with the
following:
NOTE:
Different thicknesses of material will require different Wedge Pressures.
Weld a test strip to test the material with the Wedge Pressure.
1.To adjust the pressure of the Wedge, loosen the jam nut on
the Depth Adjustment Knob.
(Figure 2.34)
2.Turn the Depth Adjustment Knob counter-clockwise until
the Wedge comes in contact with the Weld Roller Pinch
Point:
(Figure2.35)
3.Turn the Depth Adjustment Knob clockwise 2 full turns.
4.Tighten the jam nut down against the Heat System
Mounting Plate.
(Figure 2.34)
5.Check the Wedge Pressure by welding a test strip to be
certain that the Wedge is contacting the fabric with the
proper amount of pressure pushing the material into the
Weld Rollers producing a quality seam. Repeat steps 1
through 4 until correct.
