LOOPER MODULAR BLOCK OF TUFTING MACHINE AND MANUFACTURING METHOD THEREOF

To manufacture a looper modular block to be fitted to a looper bar of a tufting machine without requiring inside cutting work such as that for forming a groove or slot.SOLUTION: Tabular looper members 10, 10a which have a hook 12 at a tip of an arm 11 for engaging a pile yarn and a fitting base 13 formed at a rear end and extending in a direction substantially perpendicular to the arm 11, and a spacer 20 are disposed alternately so as to abut against each other. Connection pins 30, 31, 32 are inserted in open holes 15a, 15b, 15c of the tabular looper member and open holes 25a, 25b, 25c of the spacer. Abutting surfaces between the looper members 10, 10a and the spacer 20 and open holes 15a, 15b, 15c and open holes 25a, 25b, 25c and pins 30, 31, 32 are bonded with an adhesive for metal. A portion at which the base 13 and the spacer 20 overlap and are bonded is a fitting block to a looper bar.SELECTED DRAWING: Figure 3 【課題】タフティング機のルーパバーに取り付けるルーパのモジュラブロックを溝やスロットのような内部切削加工を必要とせずに製作しようとすることである。【解決手段】パイル糸を係止するアーム１１の先端にフック１２を有し、後端はアーム１１とほぼ直角方向に延伸して取付けベース１３を形成した板状ルーパ部材１０、１０ａと、スペーサ２０とを交互に当接させて配置し、それらの貫通孔１５ａ、１５ｂ、１５ｃと貫通孔２５ａ、２５ｂ、２５ｃに連結ピン３０、３１、３２を挿通し、ルーパ部材１０、１０ａとスペーサ２０との当接面及び貫通孔１５ａ、１５ｂ、１５ｃ及び貫通孔２５ａ、２５ｂ、２５ｃとピン３０、３１、３２を金属用接着剤で接合して、ベース１３とスペーサ２０の重なり合って接合された部分をルーパバーに対する取付けブロックとしたのである。【選択図】図３
