Definitions

  • ABSTRACT The invention relates to a device for producing a false selvedge on a fabric, comprising two rods together receiving slidingly a first and a second block, each supporting thread guides, said rods being provided at their ends with abutments for the blocks, while a spring is located between the blocks to tend constantly to separate one form the other, means moreover being provided to displace the thread guides laterally when the blocks move with respect to one another, and in this device the thread guides of the second block are mounted pivotally on this other block, the thread guides, mounted pivotally on the second block being controlled in their pivotal movement by a linking member mounted pivotally on the first block receiving the thread guide in oscillating position.
  • the particular object of the present invention is to overcome these disadvantages and relates to this end to a device for producing a false selvedge on a fabric, comprising two rods together receiving slidingly a first and second block, each supporting thread guides, said rods being provided at their ends with abutments for the blocks, while a spring is located between the blocks to tend constantly to separate one from the other, means being provided to displace the thread guides laterally when the blocks move with respect to one another, which device is characterised in that the thread guides of the first block are mounted so that they can oscillate, while the thread guides of the second block are mounted pivotally on this other block, the thread guides, mounted pivotally on the second block being controlled in their pivoting movement by a linking member mounted pivotally on the firstblock receiving the thread guide in oscillating position.
  • the device according to the invention is represented by way of a non-limitative example on the attached single drawing, which is a partially exploded perspective schematic view of the device according to the invention.
  • the object of the present invention is therefore to provide a device of robust and simple construction, and
  • the device according to the invention consists of two rods 1 and 2, preferably cylindrical, on which are slidingly mounted two blocks, block 3, called the first block, and block 4, called the second block.
  • Each of the rods 1 and 2 has at both its ends studs 5, 6, 7 and 8, which constitute on the one hand means of controlling the blocks'3, 4 and the linking plate 19, and on the other, abutments intended to limit theseparation of these two blocks when under the influence of the wire spring 9 which, in the example shown, is wound into the shape of a hunting horn and connected by its ends to each of the blocks 3 and 4.
  • the abutments-5 to 8 comprise some slots 10 intended to allow the device to be fixed onto'the blades of the harness of a weaving loom, for example.
  • these thread guides 13,, 13 13 13, are four in number but not limited to this, and are constituted by needles with eyelets 16, at their free ends through which the fastening threads intended to constitute the false selvedge are threaded.
  • first support block 3 receives a support part 14, but this part 14 can move slightly about the spindle 21 with respect to the block 3.
  • This part 14 supports in the non-limitative example shown, four thread guides 15,, 15 15 15., which also are provided with eyelets 17 at their ends for the passage of other fastening threads.
  • the second block 4 is made in the form of a frame on the edges of which slide the rods 1 and 2.
  • This frame comprises at its lower end a lateral extension 18 provided with orifices through which the thread guide needls 15 15 15 and 15., can slide, the length of these needles being such that when the abutments 5, 6, 7 and 8 rest against the blocks 3 and 4, these needles project slightly through the orifices of this lateral projection. It is therefore seen that on account of this construction the needles l5, and 15, are guided to positioned correctly and that, in addition, if any vibration occurs while the needles 15, to 15., are in their high position, these vibrations are automatically eliminated as soon as these needles reach their low position.
  • the construction also has the effect of preventing said needles entering into resonance.
  • the first block 3 which supports, in the oscillating position, the needles 15, to 15,, also receives pivotally a linking part 19.
  • the part 14 is fixed to the block 3 by means of the screw spindle 21, the screws 20 and 22 being used to fix the needles, while the linking part 19 is mounted pivotally on the screw 21.
  • the linking part 19 is constituted by, a plate, prefera bly made of metal, having two branches 19 and 19 which are joined at their free ends by a cross-piece 23 provided with orifices in which can slide the guide needles 13 to 13, mounted pivotally on the block 4 by means of the support 12.
  • the length of the branches 19, and 19, of the linking plate 19 is such that when the abutments 5, 6, 7 and 8 are all resting against the blocks 3 and 4, the cross-piece 23 is located near the eyelets 16 of the ends of the needles 13 to 13,. In consequence, as with the needles 15, to 15,, the needles 13, to 13., are protected against any vibration and resonance phenomena that might occur.
  • branches 19 and 19 of the linking part 19 pass through the slots, respectively 24 and 25, formed at the base of the lateral extension 18, this arrangement avoiding vibrations of the linking plate while simultaneously eliminating the possibility of the needles 13 to 13., vibrating.
  • one of the needles which in the examples is represented as needle 13.
  • needle 13 is of a greater length than the adjacent needles 13 13 and 13
  • This arrangement a has the result of making sure that the needles 13, to 13 do not strike the needles -15, to 15., head-on, when they cross one another because, before all the needles meet, the needle 13., has already been in contact with the end of the needle 15., and had forced all the needles 13 to 13. to pivot by means of the cross-piece 23.
  • the device operates as'follows:
  • the abutments 6 and 8 do not rest directly on the first block 3, but instead, rest on the lower edge of the linking part 19 so that the alternative resting of the abutments 6 and 8 on each of the sides of the linking part 19, pivoting at 21, causes the linking part to tip in one direction or the other.
  • a device for producing a false selvedge on a fabric comprising two rods together slidingly receiving a first block and a second block, each block supporting I thread guides, said rods being provided at their ends with abutments for said blocks, spring means located .between said blocks tending constantly to separate one block from the other, means for displacing the thread guides laterally during oscillation of the blocks with respect to one another, said device being characterized by the thread guides of the second block being mounted pivotally on said second 'block, a linking member being mounted pivotally on said first block, and said linking member having orifice means for slidingly receiving during oscillation the thread guides of said second block.
  • a device in which the thread guides of the first block are fixedly mounted on said first block and the second'block has orifice means for slidingly receiving said thread guides of the first block.
  • a device in which the second block is of such a length that when the first and second blocks are resting against all said abutments, the orifice means of said second block are located close to the free ends of the thread guides of the first block.
  • linking member is of such a length that when the first and second blocks are resting against all said abutments the orifice means of said linking member are located close to the free ends of the thread guides of the second .block.
  • the linking member comprises a plate provided with two branches joined at their free ends by a part containing said orifice means for slidingly receiving the thread guides of the second block.
  • a device in which the second block is provided with slot means for slidingly receiving the branches of said linking member.
  • a device in which the linking member has a portion protruding slightly from said first block adjacent said abutments, whereby said linking member is pivoted back and forth by alternate contact of said abutments with said protruding portion of said linking member.
  • thread guides comprise needles provided at their free ends with thread guide eyelets.
  • a device in which one of said needles is of a greater length than the others.
  • a device in which the longest needle comprises one of the thread guides mounted pivotally on said second block.
  • a device in which at the rest position the needles of the first block are mounted on the same axes respectively as the needles of the second block.
