7. FOLDING MACHINE

15. The pocket opening is not tucked in.

<Cause>

A. The flap margin is small.

Make the flap margin at least 15 mm.

B. Tucking blade L and R are improperly attached.

Slide the tucking blades forward. If this adjustment is not enough to solve the trouble, enlarge the chamfered

parts of the tucking blades by machining. At this time, remove the burrs and buff the blades.

C. Because the chamfering blades are improperly positioned, the pocket material is pressed out

when the chamfering blades go to the pocket material.

Shift the chamfering blades or the whole chamfering mechanism backward. Check that the chamfering blades

go under the pocket material.
