Definitions

  • the present invention concerns a device for forming a selvedge on a fabric, in other words a device which is designed to be used in weaving machines in order to provide for a selvedge during the weaving process.
  • the present invention aims a device for forming a selvedge with a simple construction and requiring little maintenance, whereby the above-mentioned disadvantages are minimised.
  • the invention concerns a device for forming a selvedge on a fabric comprising at least one thread guiding element for what is called a leno thread, provided on an arm, whereby this thread guiding element is provided with a thread guide and whereby at least this thread guiding element can be moved by means of a drive mechanism, such that its position can be laterally changed on the one hand, and can be changed in height on the other hand, characterised in that the above-mentioned drive mechanism comprises the combination of an oscillating drive element; coupling parts forming a connection between the drive element and the above-mentioned arm in order to move said thread guide in height; and a mechanism with which the movement of one of the above-mentioned coupling parts can be translated in a lateral movement of the above-mentioned thread guide in order to laterally change its position.
  • the device is preferably also provided with at least one thread guiding element for what is called a fixed thread, provided on an arm, which then forms a shed together with at least one so-called leno thread.
  • a 'lateral change of the position of the thread guide' should be understood among others that in the case where a thread guide for what is called a fixed thread is being applied as well, which is usually the case, the thread guide for a leno thread is situated in one position along one side of the thread guide for the fixed thread, whereas it will be situated on the other side thereof after a switching.
  • a 'change in height' is meant the altered position which is necessary for forming the shed.
  • the oscillating drive element preferably consists of a motor, in particular a stepping motor, with a motor shaft which is driven back and forth.
  • the invention is particularly useful in embodiments with at least two arms whereby these arms and/or the accompanying thread guiding elements can be moved crosswise in surfaces situated next to each other.
  • the threads concerned preferably extend directly backwards as of the thread guides, along the thread guiding elements, as is also the case in the embodiment known from WO 96/36751, and one or several of the above-mentioned thread guides are embodied as a thread guiding eye situated in a surface which extends crosswise to the surface in which the thread guiding element concerned can be moved in height.
  • a thread guiding eye situated in a surface which extends crosswise to the surface in which the thread guiding element concerned can be moved in height.
  • a further embodiment of the invention additionally comprises several thread guiding elements, including for example at least one thread guiding element for what is called a leno thread and at least one thread guiding element for what is called a fixed thread, whereby these thread guiding elements are embodied as protruding elements, in particular needle-shaped elements, provided with a thread guide at least on their front ends, whereby the threads concerned extend mainly according to the longitudinal direction of the thread guiding elements and/or extend mainly along these thread guiding elements, and whereby these thread guiding elements can be moved in height by means of a drive mechanism, whereby the above-mentioned thread guides are formed as thread guiding eyes situated in surfaces situated crosswise to the surface in which the thread guiding element concerned can be moved in height.
  • the figures represent a device 1 according to the invention which is suitable to form two selvedges 2 on fabric parts 3 formed next to each other. Also, this device 1 is made doublefold and comprises two groups of thread guiding elements whereby every group, 4-5 respectively, in this case comprises one thread guiding element 6 for what is called a fixed thread 7 and two thread guiding elements 8-9 for what are called leno threads 10-11.
  • the thread guiding elements 6 are provided on a rotatable arm 12 and are provided with thread guides 13 at their front ends.
  • the thread guides 13 can only be moved in height, in particular in planes 14-15, as indicated in figure 3.
  • the thread guiding elements 8-9 are provided on a rotatable arm 16 and they are provided with thread guides 17-18 at their front ends. Every pair of thread guiding elements 8-9 is fixed on a base 19 which can be rotated, practically over 180°, as a result of which the thread guides 17-18 cannot only be moved in height, but also their mutual position can be altered.
  • every thread guiding element 6 can hereby move through the corresponding thread guiding elements 17-18, such that a rotation of the bases 19 will also have for a result that, in one position, the thread guide 17 is situated to the left and the thread guide 18 is situated to the right of the accompanying thread guide 13, whereas in the other position of such a base 19, this is exactly the opposite.
  • the arms 12 and 16 are made as lever arms which are fixed in a rotating manner to a frame 22 by means of rotating points 20-21. These arms 12, 16 are mutually coupled, in this case by means of a coupling bar 23, such that the movement of the arm 16 results in an opposite movement of the arm 12.
  • the device 1 is provided with a drive mechanism 24 which is mainly composed of an oscillating drive element 25; coupling parts, generically indicated with reference 26, which form a connection between the drive element 25 and at least one of the above-mentioned arms, in this case the arm 16, whereby these coupling parts preferably exclusively consist of parts moving to and fro, and which thus do not rotate continuously further; and a mechanism 27 with which the movement of one of the above-mentioned moving parts can be translated in a mutual lateral shift of the thread guides 17-18 in relation to the thread guide 13.
  • the oscillating drive element 25 consists of a motor 28 with a motor shaft 29 which can be driven to and fro. More in particular, a stepping motor is preferably used to this end.
  • the above-mentioned coupling parts 26 are for example composed of a crank 30 mounted fixed on the motor shaft 29 and which thus can be rotated to and fro by means of the motor 28 on the one hand, and of a connecting arm 31 provided between the crank 30 and the arm 16, which is connected to the crank 30 and the arm 16 via hinge points 32-33.
  • the above-mentioned mechanism 27 comprises a tilting body 34 which is mounted on the arm 16 in a rotating manner via a shaft 35, as well as a cam following mechanism 36 with which the tilting body 34 can be moved.
  • the cam following mechanism 36 consists of a cam follower 37 mounted fixed on the tilting body 34 on the one hand, and of a cam guide 38 provided on one far end of the connecting arm 31 on the other hand, in particular on the far end situated opposite to the hinge point 32 in relation to the hinge point 33.
  • the tilting body 34 is connected to the bases 19 in such a manner that a tilting movement of the body 34 results in a rotation of the bases 19 over practically 180°.
  • these bases 19 are mounted fixed on shafts 39.
  • cranks 40 which mesh in a hinged manner via shafts 41 in carriages 42 sliding in guides 43 in the tilting body 34.
  • the oscillating drive element 25 is preferably coupled to a non-represented control which makes it possible for the motor shaft 29 to rotate between at least three positions, a first position in which the crank 30 is situated in a position as represented in figure 2 on the one hand, and a second and third position whereby the crank 30 is turned over a certain angle A to the one direction, over a certain angle B to the other direction respectively on the other hand.
  • these angles A and B amount to 120°.
  • the cam guide 38 is positioned and embodied such that the cam follower 37, as the drive element, i.e. the crank 30, is shifted as mentioned above from the first into the second position, makes contact with a cam guiding part N1 which leaves the lateral position of the cam follower 37 unaltered or practically unaltered, and such that the cam follower 37, as the crank 30 is shifted from the first into the third position, makes contact with a cam guiding part N2 which causes a lateral movement Z of the cam follower 37 and thus brings about a rotation of the bases 19.
  • Figures 1 to 3 represent a condition whereby the crank 30 is situated in the first position.
  • the coupling parts 26 By realising the coupling parts 26 in a fitting manner is thus obtained that the thread guiding elements 6 on the one hand and the thread guiding elements 8-9 on the other hand, seen from a side view, are situated away from each other.
  • the tilting body 34 is situated in a position as represented in figure 4.
  • crank 30 When the crank 30 is brought into the third position, in other words is rotated over the aforesaid angle B, there will first be an intermediate position, as represented in figure 12, whereby the cam follower 37 is moved along the slanting part of the cam guide 38, as represented in figure 5. As a result, the body 34 will tilt from the position represented in figure 4, over the position from figure 5, into the position from figure 6. Consequently, the cranks 40, and thus also the bases 19, will make a rotational movement of about 180°, as is schematically represented in figure 13.
  • crank 30 By controlling the crank 30 can thus be realised a selection of different selvedge weaves.
  • the device 1 can also be made simple, i.e. for forming a single selvedge weave. Nor is it excluded to work with only one thread guide 17 or 18 on a base 19, whereby only one leno thread is used then, which, as the crank 30 is turned over the angle B, will then be alternately situated on either side of the thread guiding element 6, seen from aside.
  • the threads 7 and 10-11 are preferably guided off directly to the back as of the thread guides 13 and 17-18, for example via thread guides 44-45 situated at the back on the arms 12 and 16.
  • This effect can even be further improved by using thread guides, as represented in figure 18, which are made as a thread guiding eye situated in a surface situated crosswise to the surface in which the thread guiding element concerned can be moved in height. In figure 18, this is exclusively represented for the thread guide 13, but it is clear that a similar embodiment is preferably applied to the thread guides 17 and 18 as well. To this end, the thread concerned no longer has to move in an S-shape through the thread eye, as a result of which the threads will have less friction and the risk of thread breaks is minimised.
  • crank 30 be provided directly on the motor shaft 29, and a reduction can be provided in between.
  • Such a reduction can be easily built in in the motor housing or in a separate, sealed housing.
  • the cam guide 38 can be exchangeable, as a result of which different effects can possibly be created.
  • Said cam guide 38 is also preferably open on the far ends, such that possible dust gathered therein can leave via the open ends and will not be accumulated.
  • the thread guiding element 6 is driven by its own drive mechanism, and thus separately from the drive mechanism 24 for the thread guiding elements 7-8.
  • the thread guiding element 6 can be mounted on an arm 12 in a manner analogous to that of the given embodiments, or for example on a supporting element which can be moved up and down, such as a harness.
  • a thread guiding element 8 or 9 can be provided, which can be laterally moved by means of a device according to the invention.
  • a thread guiding element apart from the aforesaid thread guiding element 8 or 9, a thread guiding element can also be arranged centrally in the extension of a shaft 39, and thus provided such that it cannot be laterally moved on the arm 16.
  • a thread guiding element should be arranged out of reach of an aforesaid thread guiding element 6, which thread guiding element 6 can then be moved for example with a harness.
  • the device 1 makes it possible to carry out a four-stroke movement as well as a two-stroke movement.
  • Figures 19 to 26 represent a variant of the invention whereby figures 19 to 21 represent the entire device 1 in different positions, whereas figures 22 to 26 represent certain parts of the device 1, seen in different positions as well as different views.
  • a first point of difference with the embodiment from figures 1 to 17 consists in that the aforesaid mechanism 27 has been built in another manner.
  • the thread guiding elements 8-9 are provided in a manner analogous to that of the preceding embodiment, on a rotating base 19, whereby every thread guiding element 8, 9 respectively, is situated eccentrically as such in relation to the shaft 39.
  • the mechanism 27 now comprises a crank-shaped part 46 which is connected to the above-mentioned shaft 39 in a fixed manner and thus forms a laterally protruding part, whereby this crank-shaped part 46 is connected to one of the above-mentioned coupling parts 26 by means of a connecting rod 47, in this case the connecting arm 31.
  • the connecting rod 47 is coupled to the coupling part 26 concerned, i.e. the connecting arm 31, via a first hinge point 48, on the one hand, and it is connected to the aforesaid crank-shaped part 46 via a second hinge point 49 on the other hand, whereby these hinge points 48-49 have rotary shafts 50-51 which extend mutually in different directions and which are provided at a slanting angle on the sides 52-53 of the connecting arm 31 and the crank-shaped part 46 respectively, in particular such that what is called a Bennet four-bar mechanism is hereby formed.
  • rotary shafts 50-51 are hereby situated at angles K1 and K2 in relation to a perpendicular on the sides 52, 53 respectively, which angles, as indicated in figures 25 and 26, are equal. Also the distances L1 and L2 indicated in figures 25 and 26 are equal.
  • Bennett four-bar mechanism consists in that, at the height of the rotary shafts 50-51, formed of shaft ends, simple rolling bearings such as ball bearings, needle bearings or cylinder bearings can be applied, which, as is known, are little subject to wear.
  • both bases 19 can be mutually coupled, such that the rotation imposed on one base 19 via the Bennett four-rod mechanisms will automatically be transferred to the other base 19. This can for example be done via a connection between the given crank 46A and a similar crank on the second base which is not represented.
  • two Bennett four-rod mechanisms can be provided which are arranged next to each other.
  • the thread guiding elements 8 and 9 are arranged in a plane which is almost perpendicular to the motor shaft 29. In case of a shift from the position in figure 19 to the position in figure 20, as well as in case of a shift from the position in figure 19 to the position in figure 21, there will be a respective lateral movement of the thread guiding elements 8 and 9.
  • a second point of difference consists in that the thread guiding elements, in figures 19 to 21, the thread guiding element 6 as well as the thread guiding elements 8-9, are provided on arms 12-16 which can rotate around points of rotation 20-21 situated in or near the central plane 54 of the weaving surface 55, and in that the bisector of the angle described by such a thread guiding element 6, 8-9 respectively, deviates hardly or not from the above-mentioned central plane 54.
  • the points of rotation 20-21 are preferably situated at distances L3-L4 from the central plane 54 which are smaller than 2 cm, and in that the bisectors concerned, if they deviate from the above-mentioned central plane 54, form an angle with the plane 54, which is smaller than 15 degrees.
  • a special embodiment of a thread guide 13 is represented in figures 27 and 28, which of course can also be applied to the thread guides 17 and 18.
  • This thread guide 13 consists of a thread eye 56 provided at the free end of the thread guiding element concerned, formed of a passage 57 extending as of the crosscut end 58 of the thread guiding element, slantingly backwards, to thereby open into the side wall 59 of the thread guiding element.
  • the passage 57 hereby preferably consists of a bore hole or the like.
  • the advantage of this embodiment consists in that the thread guided through it is hardly or not bent, as is also the case in figure 18, but that the top must not be widened and/or bent thereby either.
  • the embodiment from figures 17 and 18 can also be realised by making use of a tubular thread guiding element with a front open end and an opening in the side wall, but the embodiment from figures 27 and 28 is preferred, as dust accumulations easily occur in embodiments made on the basis of a tubular thread guiding element.
  • a wear-resistant thread guiding element can be provided at the far end of every thread guiding element concerned, in particular at the thread eye 56, for example in the shape of a ceramic cylindrical piece and/or insert piece, provided in the thread eye 56 or in the extension of the tubular part formed by the passage 57.
  • FIGS. 29 to 31 show other variants of a thread guide 13 whereby the thread eye 60 is formed of a bent wire.
  • the use of a bent wire offers the advantage that the bending of the thread 7 with respect to the thread eye 60 is more smoothly around the outer surface of the wire.
  • Such a wire can have a circular, an oval or another rounded cross section.
  • Such a thread guide can be formed quite cheaply because only a wire has to be bent.
  • the thread eye 60 can be arranged perpendicular to the length direction of the thread guide 13.
  • the thread eye 60 is arranged parallel to the length direction of the thread guide 13
  • FIG 31 the thread eye 60 is arranged at an angle with respect to the length direction thread guide 13.
  • the embodiments of figure 29 and 31 used in a device according to the invention seem preferable.
  • the other thread guides 17 and 18 can comprise such a bent wire in order to guide the leno threads 10 and 11.
  • Such rounded thread eyes 60 are especially suitable for weaving threads consisting of glass fibres, because such threads easily break when guided along an edge and will normally not break when guided around a rounded surface.
