Abstract

The present invention relates to a method for fabricating a—more particularly multi-ply—knit having definably variable transverse stability and transverse elasticity including a basic weave in at least one ply of the knit, the basic weave comprising a succession of

first courses in which most of the active needles are used in forming a loop and

second courses predominantly comprising floats having a spacing length of at least two active needles,

successive sequences of first and second courses being selected in keeping with the requirements as to the transverse elasticity and transverse stability of the knit, whereby the proportion of the first courses in the more elastic knit portions is higher than in the transverse stable portions of the knit.

Claims

1. A method of making a knit employing a flat bed machine having front and rear needle beds with active needles, the method including forming a basic knit of at least one ply by knitting a succession of courses including floats, wherein each float has a spacing length of at least two active needles, the floats in an earlier course are staggered with respect to the floats in a later course, and the spacing length of the floats varies within the knit.

2. A method according to claim 1, comprising including warp threads in the basic knit to increase longitudinal stability of the basic knit.

3. A method according to claim 1, wherein said one ply is composed of said basic knit and at least one other knit.

4. A method according to claim 1, wherein the basic knit is of at least two plies and the method comprises providing a pile thread between the two plies of the basic knit and joined alternatingly to the two plies in defined spacings by loop sinking or tucking.

5. A method according to claim 1, wherein the basic knit is of at least two plies and the floats of multiple plies are looped or tucked staggered.

6. A method according to claim 5, wherein the floats are looped or tucked staggered 1×

1.

7. A method according to claim 1, wherein the floats of successive courses of the basic knit are looped or tucked staggered.

8. A method according to claim 7, wherein the floats are looped or tucked staggered 1×

1.

24. A knit made by a method according to claim 1.

25. A knit according to claim 24, having at least first and second plies and in which the second ply differs from the first ply in number of loops or wales.

26. A knit according to claim 25, wherein the knit has an exposed ply which comprises an intarsia knit for application of a design element.

30. A seat having a frame including spaced struts between which there is tensioned a knit according to claim 24, wherein the knit is a self-supporting seat cover and provides a seating surface or backrest.

31. A seat according to claim 30, wherein the knit consists of a multi-ply structure including a seating ply and a supporting ply, said plies being joined to each other by a pile thread.

32. A seat according to claim 30, wherein the seat cover is fabricated as an elastic hose tensioned about the frame.

9. A method of making a knit employing a flat bed machine having front and rear needle beds with active needles, the method including forming a basic knit of at least one ply by knitting a succession of first courses in which a majority of the active needles are used in forming loops and a succession of second courses including floats, wherein each float has a spacing length of at least two active needles, and wherein there is a greater proportion of first courses in a first area of the knit than in a second area of the knit.

10. A method according to claim 9, wherein the knit is made in the first area with an elastic thread.

11. A method according to claim 9, wherein the floats of successive second courses are mutually staggered.

12. A method according to claim 9, wherein the spacing length of the floats varies within the knit.

13. A method according to claim 9, comprising including warp threads in the basic knit to increase longitudinal stability of the basic knit.

14. A method according to claim 9, wherein said one ply is composed of said basic knit and at least one other knit.

15. A method according to claim 9, wherein said one ply is composed of said basic knit and a net knit comprising:

first courses in which a looping thread is sunk at each needle in at least a first needle bed, the looping thread being tucked on the needles of a second needle bed in defined needle spacings,

a succession of second courses on said first needle bed including floats, the floats of successive second courses being mutually staggered,

third courses in which a looping thread is sunk at each needle in at least the first needle bed, the looping thread being tucked on the needles of said second needle bed in defined needle spacings, and

fourth courses in which the tuck is transferred back from the needles of the second needle bed to the first needle bed.

16. A method according to claim 15, wherein the net knit comprises a succession of repetitions of the first, second, third and fourth courses.

17. A method according to claim 15, wherein the net knit is of at least two plies and the method comprises providing a pile thread between the two plies of the net knit and joined alternatingly to the two plies in defined spacings by loop sinking or tucking.

18. A method according to claim 9, wherein said one ply is composed of said basic knit and a net knit and the net knit is provided in the first area of the knit.

19. A method according to claim 9, wherein the basic knit is of at least two plies and the method comprises providing a pile thread between the two plies of the knit and joined alternatingly to the two plies in defined spacings by loop sinking or tucking.

20. A method according to claim 9, wherein the basic knit is of at least two plies and the floats of multiple plies are looped or tucked staggered.

21. A method according to claim 20, wherein the floats are looped or tucked staggered 1×

1.

22. A method according to claim 9, wherein the floats of successive courses of the basic knit are looped or tucked staggered.

23. A method according to claim 22, wherein the floats are looped or tucked staggered 1×

1.

27. A knit made by a method according to claim 9.

28. A knit according to claim 27, having at least first and second plies and in which the second ply differs from the first ply in number of loops or wales.

29. A knit according to claim 28, wherein the knit has an exposed ply which comprises an intarsia knit for application of a design element.

33. A seat having a frame including spaced struts between which there is tensioned a knit according to claim 27, wherein the knit is a self-supporting seat cover and provides a seating surface or backrest.

34. A seat according to claim 33, wherein said one ply is composed of said basic knit and a net knit comprising:

first courses in which a looping thread is sunk at each needle in at least a first needle bed, the looping thread being tucked on the needles of a second needle bed in defined needle spacings,

a succession of second courses on said first needle bed including floats, the floats of successive second courses being mutually staggered,

third courses in which a looping thread is sunk at each needle in at least the first needle bed, the looping thread being tucked on the needles of said second needle bed in defined needle spacings, and

fourth courses in which the tuck is transferred back from the needles of the second needle bed to the first needle bed.

35. A seat according to claim 34, wherein the knit forms both the seating surface and the backrest, and wherein the seating surface and an outer portion of the backrest are formed by the basic knit and an inner portion of the backrest is formed by the net knit.

36. A seat according to claim 34, wherein the basic knit and the net knit are fabricated at least partially of shrink-type or elastic-type materials.

37. A seat according to claim 33, wherein the knit consists of a multi-ply structure including a seating ply and a supporting ply, said plies being joined to each other by a pile thread.

38. A seat according to claim 33, wherein the seat cover is fabricated as an elastic hose tensioned about the frame.
