Definitions
- the invention relates to a shed holding element for the weaving rotor of a row shed weaving machine according to the preamble of claim 1 and a weaving rotor and a weaving machine with shed holding elements according to the invention.
- Row shed weaving machines are multi-phase weaving machines (see e.g. EP 0 013 321), in which a plurality of weft threads that are gradually shifted against each other are inserted into moving shed weaves, a plurality of sheds being formed with a weaving rotor, each of which extends over the entire weaving width.
- the roller-shaped weaving rotor has axially aligned lamella combs with stop or guide lamellae. Between the guide lamellae, shed retaining elements are alternately arranged, which fix the up or down position of the warp threads.
- Shelf holding elements are known from EP 0 196 349, each of which has a warp thread guide section, which consists of a passage between two projections, the bottom of the passage being the high shed contact surface forms for warp threads.
- the projections have the function of the guide slats mentioned above.
- the weft is inserted using air.
- a shape is provided for individual compartment holding elements in such a way that space remains for an auxiliary blowing nozzle.
- Fig. 2 shows a cross section along the line II-II in Fig.l and
- Fig. 3 shows a detail from a weaving rotor, seen in the direction of the rotor axis.
- the compartment holding element 1 shown in Fig.l has a width b, which - compared to the length a - is shown too large in the figure. This width b is around 2 mm, while the distance a is around 10 mm long.
- the compartment holding element 1 has the following parts:
- the compartment holding element 1 is moved in the direction of the arrow P by the weaving rotor 5.
- the transverse groove 11 'in the bearing surface 11 has no functional significance and is only for manufacturing reasons.
- the compartment holding element 1 To describe the compartment holding element 1, the following designations are also introduced with reference to FIG. 1: deep compartment zone 16, lower part 17, rear part 18, upper part 19 and front part 20.
- the lower part 17 comprises the deep compartment zone 16.
- FIG. 3 shows, in addition to two shed holding elements 1 and 1 'fastened on the weaving rotor 5, a stop lamella 2 arranged between them Compartment holding elements 1 move on circles 2a and 13a.
- the warp threads 3 in the high shed position are designated 3 ', those in the low shed position 3'.
- the weft thread 4 is located in the weft thread channel 14; 2 can be struck on the cloth edge 8 of the fabric 7.
- the front cloth 7a which lies between a support surface 6 and the cloth edge 8, experiences a temporary shift when struck into a position above the support surface 6. From this position, the front cloth 7a springs back again.
- a front edge leading to the support surface 11 is formed on the front part 20 of the compartment holding element 1 as a sliding edge 200 for the warp threads.
- This edge 200 runs along a curve piece 201, on which the radii of curvature do not deviate significantly from an average value, so that the largest radius of curvature is not greater than around ten times the smallest.
- the radii of curvature of the sliding edge 200 are relatively small, but larger than the width b of the
- the projections 12 and 13 are shown in Fig.l as "ears", which have a constant thickness.
- a shape is advantageously provided in which this Taper ears 12 and 13 towards the top 120 and 130, respectively.
- a taper in the opposite direction can also be provided in the lower region of the ears 12 and 13, so that the width of the support surface 11 is greater than the width c indicated in FIG is.
- the base of the rear part 18 has the same width b. Therefore, there is a recess at the opening 140 from the upper part 19 to the rear part 18, thanks to which there is no hooking of the warp thread 3 when changing from the high to the low ply position.
- the distance between the tips 120 and 130 measured parallel to the surface of the weaving rotor 5 is the length a in FIG. 1. This distance a is larger than in known shelf holding elements. Since the distance a together with the angular velocity of the weaving rotor is minimal
- the weaving process can be carried out at a higher weaving speed if there is a greater distance a.
- the distance a is at least around five times larger than the width b.
- the front projection 130 shows in its upper region a "fleeing" end face 131 which is oriented essentially in the same way as the upper part of the curve piece 201. This is advantageous with regard to the above-mentioned movement of the blanket 7a, which is caused by the Stop slats 2 is caused. In previous forms of the compartment holding element, there were disturbances by hooking the front projection 130 onto the resilient front cloth 7a. Such a hooking does not occur in the form shown in FIG.
- the lower part 17 of the compartment holding element 1 has a waisted deep compartment zone 16.
- the waist creates additional space for the warp threads 3 ", which reduces obstructions and friction between the warp threads 3".
- the rear part 18, like the front part 20 on the sliding edge 200, has bevels 180 rounded in a yarn-friendly manner.
- a corresponding thread-friendly bevel is also provided for the second edge 202 of the front part 20 at the height of the weft channel 14.
- Shed holding elements 1 can also be used, in which only one of the projections 12 or 13 is designed as a guide element for the warp threads 3. The other may be completely absent; or there may only be a small stub for the purpose of producing a stable support surface 11.
- the compartment holding element 1 described is a monolithic structure. It can be made of ceramic material getting produced. However, it is advantageously worked out of a piece of metal.
