Definitions
- This invention concerns a device for the drive of an edge thread mechanism in weaving machines.
- the drive of such egde thread mechanisms can be provided in two ways, on the one hand dependent on the movement of the harnesses, and on the other hand by means of an independent drive.
- the present invention concerns a device of the type whereby the drive is provided independently from the harnesses.
- Independently driven edge threads mechanisms offer the advantage that they can trace their own course and that they provide their own crossing line.
- the crossing line is the place where the top and bottom warp threads cross and change position.
- edge thread mechanisms mainly consist of two parts, in particular thread guide elements which are moved up and down alternately.
- the independently driven edge thread mechanisms known hitherto make use of cams, gear racks, springs and suchlike for the drive. These classic means do not allow simple adjustments of the length of the course and the crossing line.
- these drives contain many components, which makes them voluminous, while wear can occur at a large number of places.
- release springs If use is made of release springs in order to move the thread guide elements back, this has the disadvantage that these springs are subject to much wear as they are constantly stretched out over the entire course of the thread guide elements.
- the present invention concerns a device for the drive of an edge thread mechanism in weaving machines, whereby the above-mentioned disadvantages are excluded.
- the invention aims a device with a simple construction; whereby no release springs are necessary for the thread guide elements; which allows that the length of the course and the crossing line can be adjusted in a simple way; which allows a simple mounting; and which allows that the edge thread mechanism can be mounted so close to the fell line that the thread guide elements require only a short course.
- the invention concerns a device for the drive of an edge thread mechanism in weaving machines, whereby the edge thread mechanism consists of at least two parts which make opposite movements, characterized in that they mainly consist of a drive element; a connecting element which is moved to and fro by the drive element; and a coupling mechanism between the above-mentioned connecting element and the above-mentioned parts of the edge thread mechanism which allows to drive these parts with an opposite movement, whereby this coupling mechanism consists of at least two levers which are each coupled at their first end to the connecting element and at their second end to a part of the edge thread mechanism.
- the connecting element preferably consists of a cable which extends along the weaving machine according to the weave breadth.
- the device is also provided with setting means to adjust the crossing line.
- These setting means preferably consist of movable clamps which allow that the first ends of the levers can be coupled to the connecting element at several places. This allows a simple adjustment of the crossing line.
- the levers preferably have two lever arms, which are set at an angle of 45 to 135 degrees.
- the lever arms coupled to the parts of the edge thread mechanism are preferably larger than the lever arms coupled to the above-mentioned connecting element. This construction offers the advantage that a small shift of the connecting element results in a large shift of the above-mentioned parts of the edge thread mechanism.
- the coupling mechanism and the edge thread mechanism are preferably mounted on one and the same frame which is movable along a profile which extends along the weave breadth of the weaving machine.
- the coupling mechanism can be moved in a simple way along with the edge thread mechanism after the above-mentioned clamps have been detached.
- the edge thread mechanism can be set in a simple way according to the weave breadth, depending on the place where a selvedge or a weave with catch threads must be realized.
- Figure 1 shows a weaving machine 1 which, as is known, can be equipped with one or more edge thread mechanisms 3 in order to form selvedges on the fabric 2 and/or to bind catch threads.
- such an edge thread mechanism 3 mainly consists of two parts 4 and 5 which make opposite movements A and B up and down. These parts 4 and 5 have a number of thread guides, such that the threads 6 cooperating with the latter can be woven to a selvedge 7 by means of a special weave.
- the construction of these thread guides will not be discussed in this description as it belongs to the state of the art.
- An example of such thread guides is described in Belgian patent No. 898.353 of the applicant.
- the invention consists in that for the drive of the edge thread mechanisms 3 as shown in figure 1 use is made of a device 8 which is characterized in that it mainly consists of the combination of a drive element 9; a connecting element 10 which can be moved to and fro by the drive element 9; and for each edge thread mechanism 3 a coupling mechanism 11 between the connecting element 10 and the above-mentioned parts 4 and 5.
- the drive element 9 can be chosen arbitrarily. Essentially, this drive element 9 must provide a movement to and fro.
- the drive element 9 has a lever 12 which is mounted onto a rotary shaft 13 which is driven to and fro for example by means of a cam or suchlike.
- the connecting element 10 is connected to the lever 12 by means of a fastening point 14.
- the movement of the lever 12 allows the connecting element 10 to be moved in one direction, while it can be moved back by means of a spring 15.
- For the drive element 9 use can be made for example of a dobby.
- the connecting element 10 preferably consists of a cable which extends along the weaving machine 1 according to the weave breadth.
- the coupling mechanism 11 consists of at least two levers 16 and 17, which are coupled at their first ends 18 and 19 to the connecting element 10 and at their second ends 20 and 21 to the above-mentioned parts 4 and 5.

Description
- This invention concerns a device for the drive of an edge thread mechanism in weaving machines.
- It is known that in order to form a selvedge on the fabric or to bind catch threads in weaving machines, use is made of an edge thread mechanism, in particular an appliance which allows to make special weaves, differing from the weave of the fabric.
- It is also known that the drive of such egde thread mechanisms can be provided in two ways, on the one hand dependent on the movement of the harnesses, and on the other hand by means of an independent drive. The present invention concerns a device of the type whereby the drive is provided independently from the harnesses.
- Independently driven edge threads mechanisms offer the advantage that they can trace their own course and that they provide their own crossing line. The crossing line is the place where the top and bottom warp threads cross and change position.
- Such independently driven edge thread mechanisms offer the advantage that an optimum weave can be realized, at any desired moment.
- As is known, edge thread mechanisms mainly consist of two parts, in particular thread guide elements which are moved up and down alternately. The independently driven edge thread mechanisms known hitherto make use of cams, gear racks, springs and suchlike for the drive. These classic means do not allow simple adjustments of the length of the course and the crossing line. In addition, these drives contain many components, which makes them voluminous, while wear can occur at a large number of places.
- If use is made of release springs in order to move the thread guide elements back, this has the disadvantage that these springs are subject to much wear as they are constantly stretched out over the entire course of the thread guide elements.
- As the known drives for edge thread mechanisms are voluminous, the latter must be mounted far away from the fell line, which in turn has the disadvantage that the thread guide elements must have a very long course.
- The present invention concerns a device for the drive of an edge thread mechanism in weaving machines, whereby the above-mentioned disadvantages are excluded.
- In addition, the invention aims a device with a simple construction; whereby no release springs are necessary for the thread guide elements; which allows that the length of the course and the crossing line can be adjusted in a simple way; which allows a simple mounting; and which allows that the edge thread mechanism can be mounted so close to the fell line that the thread guide elements require only a short course.
- To this end, the invention concerns a device for the drive of an edge thread mechanism in weaving machines, whereby the edge thread mechanism consists of at least two parts which make opposite movements, characterized in that they mainly consist of a drive element; a connecting element which is moved to and fro by the drive element; and a coupling mechanism between the above-mentioned connecting element and the above-mentioned parts of the edge thread mechanism which allows to drive these parts with an opposite movement, whereby this coupling mechanism consists of at least two levers which are each coupled at their first end to the connecting element and at their second end to a part of the edge thread mechanism.
- The connecting element preferably consists of a cable which extends along the weaving machine according to the weave breadth.
- Preferably, the device is also provided with setting means to adjust the crossing line. These setting means preferably consist of movable clamps which allow that the first ends of the levers can be coupled to the connecting element at several places. This allows a simple adjustment of the crossing line.
- The levers preferably have two lever arms, which are set at an angle of 45 to 135 degrees. The lever arms coupled to the parts of the edge thread mechanism are preferably larger than the lever arms coupled to the above-mentioned connecting element. This construction offers the advantage that a small shift of the connecting element results in a large shift of the above-mentioned parts of the edge thread mechanism.
- The coupling mechanism and the edge thread mechanism are preferably mounted on one and the same frame which is movable along a profile which extends along the weave breadth of the weaving machine. As the coupling mechanism is coupled to the connecting element by means of detachable clamps, the coupling mechanism can be moved in a simple way along with the edge thread mechanism after the above-mentioned clamps have been detached. In this way the edge thread mechanism can be set in a simple way according to the weave breadth, depending on the place where a selvedge or a weave with catch threads must be realized.
- In order to better explain the characteristics according to the invention, by way of example only and without being limitative in any way, a number of preferred embodiments are described with reference to the accompanying drawings, where:
- figure 1 shows a weaving machine which makes use of a device according to the invention;
- figure 2 shows a view of the part which is indicated in figure 1 by arrow F2, to a greater scale;
- figure 3 shows a variant of the embodiment according to figure 2.
- Figure 1 shows a
weaving machine 1 which, as is known, can be equipped with one or moreedge thread mechanisms 3 in order to form selvedges on thefabric 2 and/or to bind catch threads. - As shown in figure 2, such an
edge thread mechanism 3 mainly consists of twoparts parts threads 6 cooperating with the latter can be woven to a selvedge 7 by means of a special weave. The construction of these thread guides will not be discussed in this description as it belongs to the state of the art. An example of such thread guides is described in Belgian patent No. 898.353 of the applicant. - The invention consists in that for the drive of the
edge thread mechanisms 3 as shown in figure 1 use is made of a device 8 which is characterized in that it mainly consists of the combination of a drive element 9; a connectingelement 10 which can be moved to and fro by the drive element 9; and for each edge thread mechanism 3 acoupling mechanism 11 between the connectingelement 10 and the above-mentionedparts - The drive element 9 can be chosen arbitrarily. Essentially, this drive element 9 must provide a movement to and fro.
- According to figure 1 the drive element 9 has a
lever 12 which is mounted onto arotary shaft 13 which is driven to and fro for example by means of a cam or suchlike. The connectingelement 10 is connected to thelever 12 by means of afastening point 14. The movement of thelever 12 allows the connectingelement 10 to be moved in one direction, while it can be moved back by means of aspring 15. For the drive element 9 use can be made for example of a dobby. - The connecting
element 10 preferably consists of a cable which extends along theweaving machine 1 according to the weave breadth. - As shown in figure 2, the
coupling mechanism 11 consists of at least twolevers first ends element 10 and at theirsecond ends parts - The
levers pivots frame 24. Thelevers - The
lever arms parts lever arms element 10, such that a small shift C of the connectingelement 10 results in large shifts A and B of theparts - The
levers element 10 by means ofrods ends levers pivots element 10 by means ofpivots - The
levers parts rods ends levers pivots parts rods - According to the invention, the device is provided with setting means to adjust the crossing line of the
parts parts element 10. - In the embodiment shown in figure 2 these setting means consist of detachable clamping means 41 which allow the
levers element 10 at various places as desired. These clamping means 41 consist of twoclamps rail 44 which is attached to the connectingelement 10. - The
rail 44 is movable inseatings frame 24 and clamped to the connectingelement 10 by means of aclamp 47. - The
clamps rods pivots rail 44 at the desired place by means ofscrews - It is clear that different crossing lines can be obtained by mounting the
clamps rail 44 in different places. - According to a variant, the
clamps element 10, in other words without using therail 44 and the accompanyingclamp 47. When moving thecoupling mechanism 11 according to the weave breadth of the weaving machine, for example in order to realize a special weave at a different place, this method requires that at a chosen place the two clamps are set in relation to the connectingelement 10 and in relation to one another. The embodiment using arail 44, however, only requires that therail 44 is set in relation to the connectingelement 10. - In order to adjust the course, in other words the amplitude of the movement of the
parts edge thread mechanism 3, thepivots lever arms lever arms - The device 8 can also be provided with setting means to adjust the course, which are provided at the height of the drive element 9. These setting means can for example consist of a mechanism which allows that the distance Y between the
rotary shaft 13 and thefastening point 14 is adjusted. As a result the course of the connectingelement 10 can be made larger or smaller at an identical angular rotation of therotary shaft 13. - The device 8 can also be provided with means to adjust the crossing moment, in other words the moment in the weaving cycle when the threads cross and change position at the height of the
parts lever 12 to therotary shaft 13 in another angle position. - The
edge thread mechanism 3 is preferably attached to theframe 24. Theframe 24 can be moved along aprofile 54 which is mounted between theharnesses 55 and thereed 56, and which extends along the breadth of the weaving machine. Theframe 24 can be fastened to thisprofile 54 by means of clamping means 57. This construction allows that thecoupling mechanism 11 and theedge thread mechanism 3 can be mounted in any desired place in a simple way. - As the
coupling mechanism 11 is very small, meaning that the total breadth D as indicated in figure 2 is very small, thismechanism 11 and theedge thread mechanism 3 attached to it can be mounted close to thereed 56, in other words close to thefell line 58, which has the advantage that theedge thread mechanism 3 only has to trace a short course. - Mounting is preferably done, as indicated in the figures, above the fabric surface, such that the
coupling mechanism 11 is easily accessible and that all above-mentioned adjustments can be easily carried out. However, it is not excluded to mount thecoupling mechanism 11 underneath the fabric surface, whereby the appliance from figure 2 must be reversed. - Figure 3 shows a variant whereby the first ends 18 and 19 of the
levers rail 44 as mentioned above. As in figure 2, use is made ofclamps element 10 hereby results in a small movement up and down of therail 44. - The present invention is in no way limited to the embodiments described by way of example and shown in the accompanying drawings; on the contrary, such a device for the drive of an edge thread mechanism in weaving machines can be realized in several sorts of variants while still remaining within the scope of the invention.
