If the needle does not carry the twine over far enough, the twine disk, or cord holder, will grasp only one strand, and the knot will be tied only in one end of the cord, with the other extending back to the machine. This condition is shown in No. 1
. Agricultural engineering; a text book for students of secondary schools of agriculture, colleges offering a general course in the subject and the general reader. Agricultural engineering. FARM MACHINERY 249 the failure to make a complete knot. The names of the various parts of the tying mechanism may be learned from the accompanying illustration. If the needle does not carry the twine over far enough, the twine disk, or cord holder, will grasp only one strand, and the knot will be tied only in one end of the cord, with the other extending back to the machine. This condition is shown in No. 1, Fig. 155, and may be caused occasion- ally by a straw interfer- ing with the placing of the twine. When the twine disk is too tight, the symp- toms will be much like those just described, ex- cept that one end of the band will be frayed (No. 2,) indicating thatifc has been cut off by being pinched too tightly and that the spring should be loosened. If both ends are cut off irregularly, as shown in No. 3, it is quite a sure sign that the holder is too tight. If the knotter spring, which holds the finger down upon the knotter hook, is too loose and does not hold the ends of the twine while the knot is pulled over the hook forming the knot, the ends of the band will appear as shown in No. 4. The same kind of band is found when the knife cuts the twine too soon before the knotter finger has closed over Fig. 155. The ends of bands which have not been made into perfect knots.
