Definitions

  • This invention concerns a mounting for selvedge devices on weaving machines, more particularly for selvedge devices which consist of two parts which move past each other and which are carried by two successive weaving harnesses, where said harnesses move in opposite directions during weaving.
  • the invention concerns a selvedge device mounting of the type in which the parts which move past each other are attached to the weaving harnesses, or to the suspension frames of said harnesses, by means of two-part mounting brackets, where the two parts of said mounting brackets are tightened round said suspension frame by means of screw devices.
  • the present invention has as its aim a selvedge device mounting which systematically avoids the disadvantages outlined above.
  • the invention consists of a selvedge device mounting, more particularly for selvedge devices which consist of two parts mounted one behind another and which move past each other and which are carried on two successive weaving harnesses, where the mounting consists of a number of mounting brackets by which the two parts of the selvedge device are joined near their ends to the corresponding weaving harnesses, comprising at least one screw device, far attaching and tightening one of said parts to a weaving harness, which can screw in and out in a direction oblique to the plane of the harnesses, whereby said screw device cooperates with at least one of the mounting brackets of a first part of the selvedge device whilst the second part of the selvedge device, or a mounting bracket which forms part of it, has an opening which offers a passage running in the continuation of the length of said screw device.
  • the oblique direction of the above-mentioned screw device in the rear part and the opening in the front part of the selvedge device make it possible to dismount the rear part of the selvedge device in the position in which the two corresponding weaving harnesses are at the same height without the front part having to be undone or moved.
  • the above-mentioned opening in the mounting component is actually in the mounting bracket of the front part of the selvedge device.
  • the construction according to the invention makes it possible to use four universal mounting brackets, without losing the advantage of being able to dismount the rear part of the selvedge device independently of the front part.
  • Fig. 1 represents the two weaving harnesses 1 and 2, between which is mounted the selvedge device 3, here shown schematically, consisting of two parts 4 and 5 which move past each other, for example as described in US 4.478.256.
  • the parts 4 and 5 are here attached to the respective suspension frames 6 to 9 of the weaving harnesses 1 and 2 by means of a number of detachable, movable mounting brackets 10 to 13.
  • the special feature of the mounting according to the invention is that firstly, at least one of the mounting brackets 12 or 13, near the top end 14 or the bottom end 15 respectively or rear part 5, is in two parts and has a screw device 16 for attaching and tightening it onto the corresponding suspension frame 8, where said screw device 16 can be screwed in and out in a direction 17 oblique to the plane of the weaving harnesses 1 and 2, and secondly, the front part 4 of the selvedge device 3, or a mounting bracket 10 or 11 which forms part of it, has an opening 18 which offers a passage in the continuation of said screw device 16.
  • all four mounting brackets 10 to 13 are in two parts, and both mounting brackets 10 and 11 of the front part 4 of the selvedge device 3 have an opening 18 as described above.
  • the two-part mounting brackets 10 to 13 can for example consist of a hook-shaped part 19 which can be hooked behind the outside edge 20 of the corresponding suspension frame 6 to 9 respectively, and a base part 21 which can operate with the inside edge 22 of the corresponding suspension frame.
  • the screw device 16 makes the connection between the two parts 19 and 21, such that by screwing up said screw device 16 the two parts are pulled towards each other and the corresponding suspension frame 6 to 9 is enclosed tightly between them.
  • a U-shaped base part 21 such that the legs 23 and 24 of the U shape are situated in the plane of the corresponding weaving harness, while the hook-shaped part 19 fits into the U shape.
  • the ends 25 and 26 of the legs 23 and 24 are contact parts, by means of which the base part 19 can be tightened against the inside edge 22 of the suspension frame 6 to 9 respectively.
  • the necessary slots 27 and 28 are provided in the ends 25 and 26 in order to provide a seating for the corresponding suspension frame.
  • the screw device 16 consists preferably of one centrally-mounted screw or bolt, which in the preferred embodiment of the above-mentioned mounting brackets 10 to 13 consists of a socket-head screw 29 whose head 30 is countersunk in the base part 21, in particular as shown in fig. 5.
  • the parallel planes 31 and 32 of the parts 19 and 21 are preferably situated perpendicularly to the screw device 16.
  • the parts 19 and 21 are preferably dimensioned so that when they fit round the suspension frames 6 to 9 a certain amount of play 33 remains between these parts 19 and 21.
  • the side surfaces 34 and 35 in figs. 3 to 5 should preferably fit together.
  • the opening 18 made at least in the front part 4 of the selvedge device 3 should preferably also be made in the base part 21 of the corresponding mounting bracket 10 or 11 respectively.
  • the opening may be situated so that, in the position in which the weaving harnesses 1 and 2 are at the same height, the screw device 16 is accessible by means of a socket-head screw wrench or suchlike, as shown in figs. 2 and 5.
  • All the mounting brackets 10 to 13 for the selvedge device 3 should preferably have a universal form as shown in figs. 3 to 5.
  • the base part 21 here has a mounting part 36 on which the actual thread guide mechanisms 37 and 38 are mounted.
  • the opening 18 can also consist of a long, vertical slot or suchlike along the length of part 4, which can simultaneously serve as the guide slot for the thread guide element 39, itself known, which is attached to the rear part 5.
  • the angle A between the direction 17 and the plane of the weaving harnesses 1 and 2 can be from 15 to 45 degrees, and is preferably equal to 30 degrees.
  • front and rear parts of the selvedge device 3 are only used in the description in order to differentiate between parts 4 and 5.
  • said front part 4 can be nearer the shed on the weaving machine than the rear part 5 or vice versa, or in other words the side from which the screw device 16 can be screwed into the corresponding mounting bracket 10 to 13 can be either towards or away from the shed.
