Abstract

A tufting method and apparatus for tufting yarn to a backing layer, including individual tufting elements, comprising, means to select when tufting elements will be utilized during a tufting operation, means to select particular yarns from a plurality of yarns, for tufting, means to select the length of yarn increment to be tufted, means to control the distance between successive needle strokes, and means to control lateral displacement of successive needle strokes.

Claims

1. Tufting apparatus or the like comprising:

selectable tuft applying elements;

yarn feeding means including means to select yarn from a plurality of yarn types;

backing layer movement means including means of adjusting said movement; and

control means to simultaneously control the selectability of said tuft applying elements, the selection and feeding of yarn and the movement of the backing layer.

2. The tufting apparatus of claim 1 wherein said selectable tuft applying elements comprise groups of selectable tuft applying elements.

3. The tufting apparatus of claim 2 wherein for each needle station tufting needles of one of two groups may be selected.

4. The tufting apparatus of claim 2 wherein for each tufting station one of three groups of tufting needles may be selected.

5. The tufting apparatus of claim 1 wherein said selectable tuft applying elements comprise individually selectable tuft applying elements.

6. The tufting apparatus of claim 1 wherein said yarn feeding means includes pneumatic yarn transportation means to transport selected yarn to corresponding tuft applying elements.

7. The tufting apparatus of claim 1 wherein said backing layer movement means includes adjustable means for incrementally advancing said backing layer.

8. The tufting apparatus of claim 1 wherein said backing layer movement means includes means of adjusting lateral movement of said backing layer with respect to succeeding needle strokes.

9. The tufting apparatus of claim 1 wherein said backing layer movement means includes means of adjusting advancement of said backing layer and means of adjusting lateral movement of said backing layer with respect to succeeding needle strokes.

10. The tufting apparatus of claim 1 wherein said control means comprises a pattern having yarn selection data, and backing layer control data.

11. The tufting apparatus of claim 10 wherein said backing layer control data includes control data for adjusting the advancement of said backing layer and for controlling lateral movement of said backing layer.

12. The tufting apparatus of claim 10 wherein said pattern includes data for the selection and feeding of yarn which data also is used to select the tuft applying elements.

13. The tufting apparatus of claim 12 wherein said selectable tuft applying elements are actuated by solenoids.

14. The tufting apparatus of claim 12 wherein said selectable tuft applying elements are actuated by solenoids as initiated by yarn selection data.

15. The tufting apparatus of claim 1 wherein said selectable tuft applying elements are driven by a common driving means including selector elements corresponding to each individual tuft applying element.

16. The tufting apparatus of claim 1 wherein said backing layer movement means includes a shifting roll for effectuating lateral movement of said backing layer.

17. The tufting apparatus of claim 16 wherein said shifting roll is positioned immediately adjacent the location where said selectable tuft applying elements penetrate the backing layer.

18. The tufting apparatus of claim 16 further including drive means, intermediate linkage and a lever mounted at a bearing point determined by said intermediate linkage.

19. The tufting apparatus of claim 1 further including a pivot means, needle bar structure movable around said pivot means, and at least two rows of selectable tuft applying elements mounted on said needle bar structure.

20. The tufting apparatus of claim 19 further including rocker structure pivotally mounted to said needle bar structure controlling the selection of said at least two rows of tuft applying elements.

21. The apparatus of claim 20 further including actuation means engageable with said rocker structure and causing one of said at least two rows of tuft applying elements to be selected.

22. Tufting apparatus including:

a plurality of tuft applying elements;

guide means for guiding said plurality of tuft applying elements;

common driving means for driving said plurality of tuft applying elements including a plurality of selector elements for selecting said tuft applying elements; and

means for actuating each of said plurality of selector elements to select and drive said tuft applying elements.

23. The tufting apparatus of claim 22 wherein at least one of said tuft applying elements includes a first drive engagement surface engageable by a selector element.

24. The tufting apparatus of claim 23 wherein said tuft applying elements includes a second drive engagement surface, to return said tuft applying elements after tufting by driving means.

25. The tufting apparatus of claim 22 wherein each of said tuft applying elements comprises tufting needle means.

26. The tufting apparatus of claim 25 wherein said tufting needle means comprises a needle pair.

27. The tufting apparatus of claim 25 wherein the needle pair is connected at the base by a connector web.

28. The tufting apparatus of claim 27 wherein one needle member of said needle pair includes engagement means comprising an attached abutment for engagement by said driving means upon needle selection.

29. The tufting apparatus of claim 22 wherein said guide means comprises a guide block having channels to guide said plurality of tuft applying elements.

30. The tufting apparatus of claim 22 wherein the selector elements are pivotally secured to said common driving means.

31. The tufting apparatus of claim 30 wherein at least one of said selector elements includes engagement means for engaging a corresponding tuft applying element.

32. The tufting apparatus of claim 31 wherein said selector element is biased away from said tuft applying element by biasing means.

33. The tufting apparatus of claim 32 wherein said selector element has a surface magnetically engageable by said actuating means whereby when engaged said biasing means is overcome and said selector element will engage said tuft applying element.

34. The tufting apparatus of claim 22 wherein at least one of said selector key elements has a lower angulated surface and wherein said tufting apparatus further includes a selector bar which will cause said selector key to return to a position of close proximity to said actuating means.

35. The tufting apparatus of claim 22 wherein said guide means further includes an overstroke spring for limiting motion of at least one of said tuft applying elements after a tufting step is completed.

36. The tufting apparatus of claim 22 wherein said actuation means comprises a plurality of solenoids corresponding to said plurality of selector key elements.

37. The tufting apparatus or the like including:

a needle bar having first and second rows of needles placed apart from one another;
