Procedure to Adjust Vertical Slider Bearing Clearance

SAFETY - Disconnect the machine from both electrical and air supply lines before making
any adjustments or changes.
1. Remove the upper tape head from its holder.
2. Place two bars or pieces of wood of uniform thickness across the tops of side belt conveyor covers to
provide a level resting place for the upper tape head assembly and lower the cross member with the
tape head holder and/or Snap Folders until they rest on the bars.
3. Loosen the four corner bolts in each end plate that secure the cross member to the arch column just
enough so the slider bar bearings are free to be adjusted.
4. Place a screwdriver through an adjusting hole and use it to lever a slider bar bearing tighter against
the column channel flange. While holding the pressure with the screw driver, tighten the two
securing bolts through each bearing. Repeat this procedure for the other three bearings and try to
equalize the amount of adjustment between all four.
5.
Test the fit of the bearings by lifting the cross member with the adjusting hand wheel. If too much
force is required and the fit seems very tight, loosen the bolts on one of the bearings on each side just
enough to free the movement. If the fit still seems too loose and there is still excessive movement of
the tape head holder, repeat the adjusting procedure using more leverage force. If the fit cannot be
improved with greater force, the bearings are excessively worn and need to be replaced.
