Definitions

  • ABSTRACT The sley secures the reed in place by means of one or more clamping members disposed in the groove-shaped indentation alongside the reed
  • the clamping members can be of wedge like construction to clamp the reed in place or can be of a deformable material which is deformed so as to clamp the reed in place.
  • the clamping members can also be spring loaded to ensure a sufficient clamping force on the reed.
  • This invention relates to a sley and more particularly to a sley having a clamping member. for securing a reed in place.
  • sleys have been known in which a reed is received within a grooved indentation extending along the longitudinal orientation of the sley. Such sleys have generally received the bottom or base part of the reed within the indentation and'have had means for mounting the bottom part therein.
  • mount the reed by means of a plurality of thrust screws disposed in a flange part of the sley section and adapted for stressing against the side wall of the reed base.
  • the base part and, therefore, the binder dent of the reed with the dents bonded therein may be deformed.
  • These deformations have been especially acute in reeds in which the dents are mounted in a plastic collar and particularly in fine gauge reeds in which thin dents are disposed at close distance from each other as such may cause weaving faults.
  • the invention provides a sley with a grooved indentation for receiving a reed base and a clamping member which is inserted in the indentation adjacent a supporting surface of the sley section and is stressed i.e. resiliently biased against a surface of the reed base.
  • the clamping member serves to uniformly distribute the thrust forces which act on the reed base when mounted in the sley over a surface which is substantially greater compared to a screw cross-section.
  • the clamping member is constructed in wedge form and the supporting surface of the sley section and a superficial base part facing this section include between them an angle of inclination which corresponds to the angle between the wedge surfaces of the clamping member.
  • the supporting surface of the sley section is formed by a flank of the indentation which has an angle of inclination such that the flank extends the indentation outwardly from its bottom part.
  • the angle of inclination between the supporting surface of the sley section and the corresponding surface part of the base in the unstressed state is made smaller then the angle between the wedge surfaces of the clamping piece by an amount corresponding to the elastic deformation of the sley section which occurs when the clamping members are stressed.
  • the deformation of the sley section is taken into account by virtue of the fact that one of the cooperating contact surfaces, preferably a clamping piece surface which faces the supporting surface of the sley section, is provided with a barrelled part which bears on the corresponding mating surface for any operative position of the clamping member.
  • the clamping member is constructed of elastically deformable, for example rubber-like material. This provides a particularly simple reed mounting means which can be produced with little effort and can be easily installed.
  • clamping member mounting means which contain a spring element in active association with the clamping member.
  • the spring element may be disposed between the clamping member and a corresponding part of the sley section.
  • the spring element it is appropriate for the spring element to be so disposed that the spring force acts against the insertion direction of the clamping member so that when the mounting means are released, the clamping member may be lifted from the reed base thus releasing the reed.
  • the spring element may also be disposed between an abutment surface situated on the mounting means and a corresponding part of the sley section or an abutment surface associated with the clamping member.
  • the spring force may act in the insertion direction of the clamping member so that the thrust force is supplied by the spring element.
  • FIG. 1 illustrates a partially drawn sley with a reed mounted therein according to the invention
  • FIGS. 2 and 3 each illustrate respective views taken along lines IIII and III-III of FIG. 1;
  • FIG. 4 illustrates a view similar to FIG. 3 of a modified clamping member having a barreled surface facing a sley flank according to the invention
  • FIG. 5 illustrates a view similar to FIG. 3 of a deformable clamping member according to the invention
  • FIG. 6 illustrates a view similar to FIG. 5 of a spring biased deformable clamping member according to the invention.
  • FIG. 7 illustrates a view similar to FIG. 6 of a modified clamping member according to the invention.
  • a sley 1 of a loom (not shown) is mounted by means of screw fasteners 3 and nuts 3a on a plurality of sley levers 2 only one of which is shown for clarity.
  • the sley 1 extends substantially over the entire weaving width of the loom.
  • the sley levers 2 are mounted on a shaft (not shown) coupled to the machine drive by means of which pivoting motions are imparted to the sley l in accordance with the arrow (FIG. 2).
  • the sley 1 has an approximately U-shaped section with a groove-shaped indentation 6 formed between two flanges 4, 5 and extending over the entire length of the sley 1.
  • a reed 7 mounted in the sley 1 has two horizontal binder dents 8, 9, two end bars 11 for connecting the dents 8, 9 only one of which is shown and a plurality of dents 12 distributed over the weaving width and bonded in the binder dents 8, 9.
  • the lower binder dent 9 is mounted on a base part 13 which is inserted between the flanges 4, 5 of the sley 1.
  • the sley indentation 6 is formed of a floor, a flank 14 which extends perpendicularly to the floor and an inclined flank 15 which increases the indentation 6 upwardly from the floor.
  • the width of the indentation 6 at the floor level is approximately equal to the width of the base part 13 while the base part 13 has one side wall 16 adjusted to bear against the flank 14.
  • a plurality of cuniform clamping members 18 are distributed over the weaving width in the space formed between the side wall 17 of the base part 13 and the inclined flank 15.
  • Each of these members 18 has a wedge surface 19 which bears against the side wall 17 of the base part 13 while another wedge surface 20 bears against the flank 15.
  • the angle between the side wall 17 and the flank 15, functioning as a supporting surface, is smaller than the angle between the wedge surfaces 19, 20 of the clamping member 18 by a defined amount which corresponds to the elastic deformation of the flange 5 which occurs in stressing.
  • Each of the wedge surfaces 19, 20 are subdivided by a groove-shaped recess 21 to enable each surface to bear more readily against the corresponding mating surfaces.
  • Appropriate recesses 22, which increase the indentation, are provided for the heads of the mounting screws 3 in the sley section so that the upper edge of each screw head is disposed in the same plane as the floor of the indentation 6. Accordingly, the reed 7 may be inserted into the recess 6 without being impaired by the mounting screws 3.
  • each of the clamping members 18 is retained by a screw 23 which traverses through the wedge surface 20 and the flank 15.
  • the screw 23 is disposed in a tapped hole 27 situated in the sley section and has a head 24 with an internal hexagon socket while a washer 25 is inserted between the head 24 and the clamping member 18.
  • the shank of the screw 23 extends through a bore in the clamping member 18 which surrounds the shank with a lateral clearance.
  • the bore in the sley section and in the clamping member 18 communicate with recesses 28, 29 which are open relative to each other and have a larger diameter.
  • a helical spring such as a compression spring 26 is positioned in these enlarged recesses 28, 29 to surround the screw 23 and to thrust the clamping member 18 against the head 24 of the screw 23.
  • warp threads (not shown) which are distributed across the weaving width are guided between the reeds 12.
  • these warp threads are divided in known manner to form a shed into which a weft thread is picked during each operating cycle of the loom.
  • the reed 7 is moved by a pivoting motion of the sley l (arrow 10) into the position illustrated in FIG. 2 with the weft thread being beaten by the dents 12 in the apex of the shed against the edge of the fabric which is formed thereat.
  • the reed 7 is pivoted and a new weft thread is picked which is then beaten into the position illustrated in FIG. 2 by a further pivoting motion of the reed 7 and so on.
  • the sley 1 is provided with a clamping member 31, the wedge surface 20a of which is provided with a barrelled part 32.
  • the clamping force of the flange 5 is transferred at practically every stage of its deformation at the same position, that is, over the barrelled part 32, to the clamping member 31.
  • the thrust force to be transmitted to the reed base 13 acts on the reed base 13 after being uniformly distributed over the flank 19.
  • the sley 33 is provided with a recess or indentation 34 having parallel flanks 14, 35.
  • a block-shaped deformable elastic clamping member 36 constructed of rubber or like resilient material is inserted in place of the cuniform clamping member between the side wall 17 and the flank 35.
  • the clamping member 35 is also provided with a continuous bore for passage of the screw 23 while a thrust washer 37 is inserted between the clamping member 36 and the head 24 of the screw 23.
  • tightening of the screw 23 causes deformation of the deformable elastic clamping member 36 and causes the member 34 to be stressed against the base part 13 and the flank 35. That is, the member 36 is bulged laterally to engage against the base part 13 and the flank 35.
  • a compression spring 38 is disposed between the screw head 24 and the thrust washer 37.
  • This spring 38 provides the required thrust force for deformation of the clamping member 36 when the screw 23 is tightened.
  • This arrangement offers the advantage that the thrust force is maintained substantially constant by the stressed spring 38 even in the event of fatigue of the elastic material which may occur after some time.
  • the sley 39 has a screw 23 inserted from the underside of the sley section through a continuous bore into the recess 34 and through the resilient clamping member 36.
  • the free end of the screw 23 extending from the clamping member 36 is provided with a nut 40 which is stressed against the clamping member 36 through a thrust washer 25.
  • the spring 38 is disposed between the screw head 24 and a corresponding part of the sley profile and exerts a thrust force in the manner as described above on the clamping member 36.
  • the resilient clamping member 36 as shown in FIGS. 5 to 7 can be constructed in a manner similar to that in which the clamping members 18, 31 are constructed or can be constructed as an integral piece which extends over the entire length of the sley and which is pressed into the recess by screws 23 disposed at regular distances from each other. Similarly, the clamping members 18, 31 may extend over the entire length or part of the length of the sley.
  • the inclined flank of the indentation 6 may have a barrelled part.
  • a spring element similar to spring 38 may be disposed between one of the wedgeshaped clamping members 18, 31 and the screw head 24, respectively.
  • the clamping members are retained in the indentation by means of spring elements secured on the sley section so as to dispense with mounting screws 23.
