Definitions
- the invention relates to a strand and its support rail as well as from the mounting rail and sitting on strands educated system.
- Weaving machines have shafts for shedding Strands, which are held on mounting rails.
- the heald shafts become in operation to the shedding back and forth emotional.
- the specialized education must be done faster and faster, which leads to high dynamic loads on the heald bars and leads the strands.
- the heddle according to the invention has a comparison to known healds reduced end eyelets on whose inner. Free space has a height of at most 19.5 mm. Alone This measure already leads to a weight reduction the end eyelets against ISO-compliant end eyelets.
- the diminished Mass reduces the forces to accelerate and Braking the strands are required considerably.
- the healds results in the possibility the working speed of a corresponding weaving machine to increase.
- the invention has a tendency to be used stiffer shafts against. Is the height of the Free space of the c-shaped end eyelet to a value of at most 19.5 mm and is the height of the Litzentragschiene For example, at 18 mm results in a longitudinal play (Axial clearance) of the strands to a maximum of 1.5 mm. Compared to conventional Stranded Rail Systems is the longitudinal game the strands reduced by about a factor of 2 to 3. in the Interaction with the use of sturdy heald frames, can higher speeds are achieved. The lower one Litzenspiel reduces especially when using the stiffer healds disturbing noise and wear on the Litzentragschienen and Litzenendösen.
- the reduced height of the free space of the end eyelet leads to a reduced length of the end eyelet.
- Endösenabstand thus decreases the outer total length of the strands.
- the hive therefore needs to take up the strands less space, causing the shaft rods while retaining the outer dimensions of the weave a larger, in the direction of movement of the heald to be measured width can.
- You will be much stiffer, which in turn in the sense of increasing the working speed of the weaving machine can be exploited.
- the heddle support rail preferably has only still a width of about 1.5 mm, at least in a preferred embodiment, at least one Side with a longitudinally extending recess or more provided in a series arranged individual wells is.
- This depression serves on the one hand to the heald bar easier and on the other hand, the attachment of the Litzentragschiene to a shaft profile or on a connecting means to the shaft profile in a simple and secure way to enable by means of several rivets.
- recess or groove may be a semicircular head of the rivet, without the displaceability to hinder the strands.
- the groove or recess is also advantageous because a sufficient countersink for the rivet head in the 1.5 mm very thin shaft support rail no longer possible with sufficient certainty is. The effort required to meet tight tolerances to achieve functional reliability would be too high and thus uneconomical.
- a system of Litz and Litzentragschienen created by the standardized dimensions avoids given disadvantages and a optimal design of the system allows, thereby reducing the cost reduced production and cost effectiveness the weaving machines equipped with it is improved.
- FIG. 1 illustrates a heddle 1 which an upper shaft rod 2 and a lower parallel spaced has arranged for this second shaft rod 3.
- the ends of the shaft rods 2, 3 are by side struts 4, 5 interconnected, making a solid rectangular frame is formed.
- At the top and the lower shaft rod 2, 3 is each a strand support rail 6, 7 held, as is apparent from Figures 2 and 3.
- the heddle support rail is preferably in shape a flat steel profile whose width B preferably at most 1.5 mm and its height H preferably 18 mm.
- the cross section is approximately rectangular, with the heddle support rail 6, 7 at its top with a Rounding is provided.
- strands 14 are parallel and held at a distance to each other, being with at both ends provided c-shaped end eyelets 15, 16 on the Litzentragschienen 6, 7 sit. Between the end loops 15, 16 extends itself a straight, flat shaft, the approximately center is provided with a thread eye 17.
- the strand 14 is shown in FIG 5 separately illustrated. Which is between the two End eyelets 15, 16 extending shank is preferably parallel flanked bounded by two straight edges 18, 19. If necessary, can the shaft in the area of the thread eye 17 also be enlarged to allow larger eyelets.
- the shaft arranged approximately centrally to the end eyelets 15, 16.
- the end eyelets 15, 16 are formed substantially equal to each other.
- the shank expands towards the end eyelet on the full width B2 of the end eyelet, which is preferably 4.5 mm is.
- other widths be provided, such as the usual today 5.56 mm, but the dimension of 4.5 mm is preferred. It works the shaft in a root portion 21 of the respective end eyelet 15, 16 about.
- Both end loops 15, 16 are essentially Equally formed, so the description below applies equally to both end eyes 15, 16.
- a Reihloch 22 is formed, for example in the form of a round opening. Furthermore extends from the root portion 21, a spine web 23 away, whose length is 18.5 mm to 19.5 mm. His Width is 1.5 mm to 2 mm.
- the back bridge 23 carries at its end facing away from the shaft end a head area 24, the upper limit for the end eyelet 15 or the lower limit for the end loop 16 forms.
- the free ends of the Legs 25, 26 define a passage between each other with a width W which, depending on the height of the heddle support rail, between 3 mm and 10 mm.
- the width W is much lower as the height H2 of an inner space between the root area 21 and the head area 24 included is and for receiving the heddle support rail 6, 7 serves.
- the width of the legs 25, 26 is smaller as that of the spine ..
- the height H2 is around 0.5 mm up to 1.5 mm larger than the height H of the heddle support rail. It a minimum axial or longitudinal play of 0.5 mm is provided, when the shaft rods 2, 3 designed particularly stiff are. For lower working speeds of the weaving machine or softer shaft rods, the game, i. the difference increased up to 1.5 mm between H and H2. Neither the heddle support rail 6, 7 still on the shaft rod 2, 3 still on the strands 14 clamping or spring means are provided, the free but slight play of the end eyelets 15, 16 on the Litzentragschienen could restrict 6, 7.
- FIG. 5 illustrates, at least one of the end eyelets 15, 16 at both in the root area 21, mutually parallel edges embossments 27, 28 are provided be that serve as Separierkanten and separating flat lying strands facilitate.
- Length L between the inner edges of the two end loops 15, 16 is to measure about 5 mm shortened.
- the increase in height is indicated in Figure 2 with "Z".
- the strands 14 have a Axial play (transverse to the Litzentragschienen 6, 7) of only 0.5 mm to 1.5 mm.
- the reduced mass of the end eyelets 15, 16 and the Litzentragschienen 6, 7 also reduces the required acceleration forces, which increased working speeds allows.
- the end eyelets 15, 16 with a lateral Bend or curl be provided to a certain extent to produce spring elasticity.
- the strands can 14 with shortened end eyes 15, 16 according to FIG. 6 or 7 also be prepared asymmetrically. In this case is the shaft against a center line 29 to the spine 23rd towards ( Figure 7) or away from this ( Figure 6).
- Both Strands 14a, 14b can, as Figure 8 illustrates, in a Webschaft be arranged alternately.
- Strands 14, 14a, 14b can thread eyelets in all desired forms are provided. It can therefore the existing automatic Einziehmaschinen further used become.
- a strand 14 according to the invention is characterized reduced end eyelets 15, 16 made of, which Litzentragschienen 6, 7 are associated with reduced cross-section.
- the axial play the strands on the Litzentragschienen 6, 7 is on 0.5 mm to 1.5 mm limited.
- the side play is in the Range from 0.2 mm to 0.5 mm. This from Litzentragschienen and strands formed system is particularly suitable for particularly stiff healds for looms with the highest Working speed.
