Section I – Introduction Continued Simultaneously, the twine arm is continuing its arc and the knotter body turns counter clockwise opening the jaw for the two strands of twine which are wrapped around the knotter body assembly. The strands of twine are brought through the jaws and the jaws firmly lock. The knotter body assembly then moves towards its finished position and the stripper forces the twine strands off the knotter body jaws, into the tight part of the knot. As the two strands of twine are pulled into loops from the knotter body assembly jaws, the knifetrap moves forward and cuts a...

Threading Procedures Before the tying machine is shipped, it is threaded through each guide starting from the twine container to the stringholder button. To avoid threading problems in the future, you should become familiar with the threading sequence at this time. Complete threading of the tying machine can be avoided if the end of the twine or tape being used is caught before it leaves the twine container. This is accomplished by simply tying the end of the existing twine or tape to the starting end of the new twine or tape with a square knot. If the end of the twine or tape is not caught before...

The Quality Knot Tells the Story THIS IS A PERFECT KNOT A perfect knot, like the illustration, has two long even loops extending out one side of the knot with one short and one long end, the body of the knot is tight and hard. The stripper should be on the line where the upper and lower jaws meet at the lip of the lower jaw and very little space between them as the stripper comes down to push the twine off of the knotter. Important! Your BUNN PACKAGE TYING MACHINE will tie perfect knots every time when in proper adjustment. B. H. Bunn Company 2730 Drane Field Road Lakeland, Fl 33811-1395 Phone...
