Definitions
- the present invention relates to knitting machines of the type known under the trade name Arachne" by which a base sheet which may consist of a fiber fleece, or be a woven or knitted fabric, is provided with Wales of warp knitted pile loops.
- an embodiment of the invention comprises a knockover comb, a support comb, and a stationary, but adjustable plush comb.
- the knockover sinkers of the knockover comb, the support prongs of the support comb, and the plush sinkers of the plush comb register with each other and form registering gaps open in the transporting direction of a base sheet which is guided through the passage between the knockover sinkers and the supporting prongs.
- Thread guides are disposed outward of the plush sinkers for feeding pile thread to a row of needles which have books and are movable in a forward stroke from a retracted position to an advanced position penetrating the base sheet and passing through the registering gaps so that the hooks of the needles are located outward of the plush sinkers for receiving pile thread from the thread guide.
- pile loops are formed on the stationary plush sinkers and pulled through knocked-over old loops. In this manner, a course of pile loops is formed which moves with the base sheet in the transporting direction on the pile sinkers beyond the free ends of the same and out of the registering gaps.
- FIG. 1 is a fragmentary sectional view illustrating the apparatus of the invention
- FIG. 2 is a sectional view taken on line A-A in FIG. 1;
- FIG. 3 is a schematic view illustrating a base sheet provided with a pile in accordance with the invention.
- FIG. 4 is a fragmentary sectional view illustrating the plush comb in a different position than shown in FIG. 11;
- FIG. 5 is a fragmentary perspective view illustrating the plush comb.
- FIG. 6 is a fragmentary perspective view illustrating the support comb and its supporting means.
- a base sheet is transported by transporting means, not shown, in the direction of the arrow B in FIG. 1.
- a knockover comb located on one side of base sheet 20 has a row of knockover sinkers 4a, and a carrier portion 4 mounted on a support bar 3 which is secured to another support 2 mounted on the frame 1 of the machine.
- the supporting comb 6 On the other side of the base sheet 20, the supporting comb 6 is arranged which has supporting prongs 7 respectively registering with the knockover sinkers 40 so that the gaps between the same also register, and permit the passage of needies 16 provided with latches l7 and mounted on a needle bar 18 which is reciprocated in the direction of the arrow S by an arm 19. Support comb 6 is secured by screws 111 to an angular supporting means 5.
- a stationary plush comb is disposed which has a row of plush sinkers 16 which respectively register with support prongs 7 so that the gaps between plush sinkers also register with the gaps between support prongs 7 and permit the passage of the needles 16.
- Plush comb 9 is fixed to a mounting member 3 by screws 12, and has a bottom face sliding on the top face of a portion 5a of supporting means 5. Screws 13 pass through slots M, see FIG. 6, into threaded bores of the mounting portion 6, and as is best seen in FIG. 6, the plush comb means 8, 9, 110 can be adjusted along slots 14 and then secured by screws 13. Supporting portion 5a is secured by screws 15 to another portion of the supporting frame.
- the distance between the registering plush sinkers and supporting prongs can be varied, but during operation of the apparatus, screws 13 fixedly secure the plush comb at a desired distance from the supporting comb and from the base sheet 20.
- the supporting prongs 7 are either parallel to the plush sinkers 110, or define a small acute angle with the same.
- support portion 5a carries at its ends abutment blocks 23 which serve as stops determining the position of mounting portion 8 of the plush comb.
- the abutment blocks 23 assure that the plush sinkers l0 accurately register with the supporting prongs 7, and with spaces between adjacent needles 16.
- the row of plush sinkers 110 must be parallel to the row of support prongs 7 across the width of the base sheet 20. This can be achieved by correspondingly adjusting the screws 13 in slots 14 at the ends of supporting portion 5a.
- a pile fabric made by the apparatus has pile loops 21a on one side, on the left side as viewed in FIG. 1, and on the other side of the base sheet 20, face loops 21b of pile thread 211, shown in broken lines.
- the feeding thread guides 22 are operated in a known manner so that a tricot binding is produced.
- the back loops of the pile thread 21 are laid over the plush sinkers 10 so that the pile loops 21a are formed.
- the length of the pile loops 21a varies depending on whether the pile thread 211 is laid over one plush sinker 10 in a tricot binding, or over two plush sinkers 10 in a plain binding. It is also possible to lay the pile yarn over more than two plush sinkers 110.
- the base sheet is transported parallel to the plush sinkers 10.
- FIG. 2 shows the needles 16 in retracted position having pulled the pile thread 21 through three aligned gaps between knockover sinkers 40, supporting prongs 7, and plush sinkers 10. It is apparent that the length of the formed pile loops 21a depends on the adjusted distance between the plush comb 9 and the base sheet 20 which is guided by support comb 7 and knockover comb Sincethe base sheet is transported in the direction of the arrow B, each newly formed course is transported from a position in the region of the supporting prongs 7 to a position in which the thread is no longer located in the gap between supporting prongs 7, but passes beyond the same. In this position, and preferably for at least three courses, the pile loops are held by the plush sinkers 10 which project beyond the ends of the supporting prongs 7. The projecting end portions of plush sinkers 10 shape and hold three pile loops before releasing each course. In this manner, the length of the pile loops cannot be reduced by the pull exerted by the needles 16 during the return stroke to the illustrated retracted position.
- Pile loops of different lengths can be made by adjusting the relative position of support prongs 7 and plush sinkers 10 in direction of the needle movement, as has been explained with reference to FIGS. 1 and 4.
- the fabric made by the apparatus of the invention is particularly suitable for carpets and furniture covers.
- Apparatus for forming a knitted pile on a base fabric moving in a transporting direction comprising a knockover comb and a support comb, said combs including carrier portions and rows of knockover sinkers and support prongs projecting in said transporting direction from the respective carrier portion, said rows of knockover sinkers and support prongs forming a passage for the base sheet; a stationary plush comb on the side of said support comb remote from said knockover comb, and including a mounting portion and a row of plush sinkers projecting in said transporting direction from said mounting portion, said knockover sinkers, support prongs, and plush sinkers registering with each other and forming registering gaps open in said transporting direction; thread guides disposed outward of said plush sinkers for feeding pile threads; and a row of needles having hooks and being movable in a forward stroke from a retracted position in which said hooks are located outward of said knockover sinkers, and an advanced position penetrating said base sheet and passing
