No. 321,915

4 Claims. (Cl. 66-86) The present invention relates to Warp knitting machines, especially to the attachment of thread guides.
In known machines for the production of flat fancy fabric, the thread guides are detachably mounted on the guide bars. They are usually screwed either to the outer side or, by means of a beveled, forked end portion, to the top side of the bar.
In either case it is disadvantageous that the guide bars have a considerable number of threaded holes seriously weakening the cross-section of the bar.
It is an object of the invention to improve the construction of warp knitting machines and to avoid said holes in the guide bars.
Another object of the invention is to permit, in a simple manner, replacement and precise positioning of the thread guides at arbitrary locations along the guide ars.
According to the invention, we provide the guide bars with longitudinal grooves on their respective top sides, and the thread guides with clamping means engaging the grooves and the bottom side of the bars, respectively.
In a preferred embodiment, the shafts of the thread guides are resiliently clamped to the longitudinal groove in the guide bar. A screw with a clamping bracket or clamping spring is suitable for this purpose. Each thread guide shaft carries a stop adapted to rest against the bottom side of the bar.
The shafts may also be supported at two points on the bottom side of the bar. In cooperation with the top clamp, this results in a three-point support and therefore in an extremely reliable, well-defined attachment of the thread guides on the guide bars. Due to the groove on the top side of the bar, it is possible to easily adjust all of the thread guides to any desired position without the necessity to drill a correspondingly large number of threaded holes into the bars.
We have found it advantageous to slant the bottom surface of the guide bars, thus forming a sharp edge directed towards the shafts of the thread guides which rest against this edge with one or more stops or lugs. However, the counter support for the top clamp may also consist of an edge or elongated projection provided at the outer side instead of the bottom side of the bar.
An embodiment of the invention will now be described with reference to the accompanying drawing, in which FIG. 1 shows a side elevation, partly in section, of the guide bars of a Rachel machine;
FIGS. 2 and 3 show the attachment of the thread guides to the guide bars;
FIGS. 4 to 8 show details of the mounting means according to the invention.
In FIG. 1, an arrangement is shown comprising a supporting structure 1 carrying two basic guide bars 2, 3 and twenty-two guide bars 4 for the patterning operation. The guide bars are free to swing around a fixed shaft 5 and may further be adjusted on the shaft in axial direction.
As shown particularly in FIGS. 2 and 3, the thread guide-s consist of a shaft 6 to which is secured an eyepointed needle 7. The top end of the shaft is overturned to surround the top side 8 of the guide bar 4, .see FIGS. 4 and 5. The top side of the bar is provided with a longitudinal groove 9, in which ahe thread guide shaft is fastened with a clamping bracket 10 shown in detail in FIGS. 6 and 7. The lower part of the clamping bracket is bent to form a butt member 11 fitting into the groove 9. It is forced into the groove 'by a screw 12 (FIG. 8). Two lugs 13, 14, cut partially out and bent off the shaft 6, engage the edge of the slanted bottom surface 15 of the guide bars and serve as counter support.
The clamping bracket 10 and the two lugs 13, 14 thus ensure a reliable three-point support of the thread guide shaft 6 on the guide bar 4. Replacement and adjustment of the thread guides may be effected in the most simple way just by loosening the screw 12. The thread guide can then easily be slid in the groove 9 or removed. The bottom surface 15 of the guide bar 4 is slanted towards the thread guide shaft 6 which is resting evenly against the outer side of the guide bar 4.
It will be obvious to persons skilled in the art that modifications of the specific embodiment described are possible without departing from the scope of the invention.
We claim:
1. In a warp knitting machine comprising numerous guide bars each carrying a plurality of thread guides, each of said guide bars having a longitudinal groove on its top side, each of said thread guides being provided with clamping means adapted to engage the respective guide bar at said groove and at its bottom side for attachment at a desired position along said bar.
2. In a warp knitting machine according to claim 1, each of said thread guides comprising a shaft, stop means and resilient fastening means connected with said shaft for engaging the bottom side and the groove, respectively, of said guide bar.
3. In a Warp knitting machine according to claim 1, each of said thread guides comprising a shaft, two lugs provided at said shaft, and a resilient clamping bracket connected to the top side of said shaft, said lugs and said clamping bracket engaging said guide bar and constituting a three-point support of said thread guide.
4. In a warp knitting machine according to claim 1, said guide bars having each a slanted bottom surface forming an outer edge for support of the shafts of said thread guides.
