Definitions

  • the present invention relates to an apparatus for crimping groups of synthetic filaments, also called tows, which comprises a pair of rollers and a compression compartment provided with a movable, that is, a swivelable plate for holding the material back in the compression compartment and producing an adequate compression force.
  • the crimping devices are the most critical, necessitating very careful and lengthy maintenance.
  • the device In order to produce a perfectly uniform crimp of the filaments, the device must at all times be absolutely clean and correctly adjusted.
  • the well-known forms of construction of the crimping device have to be dismounted, i.e., the compression compartment must be removed. This dismounting and remounting as well as the subsequent readjustments are very time consuming. This is the reason why the cleaning works are generally delayed as long as possible, even though this results in a somewhat inferior crimping effect. Very often, manufacturers install additional crimping devices in order to be able to dismount and clean the devices in turns.
  • An object of the present invention is to avoid the prior art disadvantages in crimping textile materials.
  • Another object of the present invention is to provide a crimping device which produces a uniform crimp and which can be much more easily cleaned and maintained.
  • the above-mentioned disadvantages may be eliminated and a much improved crimping device can be achieved by supporting the compression compartment and the movable plate to be swivelable, the movable plate being swung out to one side and the compression compartment to the other.
  • the pressure cylinders e.g., compressed air cylinders
  • an appropriate pressure rod system which is connected to the swiveling machine elements.
  • the compression compartment and the movable plate can be fixed by means of a mechanical quick-action lock, e.g., an eccentric crossbar.
  • pressure cylinders for fixing the compression compartment and the movable plate in the operating position. These elements are then pressed against buffers by means of a certain amount of pressure force and maintained in the operation position.
  • FIG. 1 shows the apparatus of the present invention in operating position
  • FIG. 2 shows the apparatus of FIG. 1 in the cleaning position.
  • the apparatus of the present invention comprises a pair of rollers with a stationary top roller 1 and a swivelable bottom roller 2.
  • the groups of synthetic filaments (not shown in the drawing) are pressed into a subsequent compression compartment 3.
  • This compression compartment 3 has a swivelable bottom plate 4 and a top plate 5 which is stationary in operating position and rigidly connected to sideplates 6.
  • the movable plate 4 as well as the rest of the compartment, i.e., elements 6 and 5 are supported to be swivelable around an axis 7.
  • these compartment elements 4, 5, and 6 are connected to compressed air cylinders 9, permitting the elements 4, 5 and 6 to be swung out into a cleaning position as well as to fix these compartment elements 4, 5 and 6 in the operating position.
  • the bottom roller 2 is supported to be swivelable around an axis 10 and in the operating position it is pressed against the top roller 1 by means of another pressure cylinder II. For cleaning purposes is can be moved downwards, as shown in FIG. 2. Since the movable plate 4 is supported on a traverse 13 on which also the roller 2 is supported, this moving-down action permits the swinging out of element 4 as well as the rest of the compression compartment, i.e., elements 5 and 6. At the sideplates 6 of the compression compartment 3 are provided with lamellas 12 which seal off the compression compartment against the rollers 1 and 2 when being set to operating position.
  • the axis 7 is supported on sideplates 14 which are in turn swivelable around the axis of the roller 2 so that the movable plate 4, the axis 7 and the sideplates 14 can be moved upwards by means of the pressure cylinder 9 until the bottom plate 4 is in contact with the top plate 5.
  • these elements are maintained in this position until the compression force is produced.
  • the moved-up elements are then pressed into the position which is shown in FIG. I.
  • a device for crimping groups of textile filaments which comprises a pair of opposing rollers disposed one above the other, one of said roller being mounted in a stationary manner and the other of said rollers being swivelably mounted, a compression compartment comprising a swivelable bottom plate and a top plate which is stationary in operating position and rigidly connected to sideplates, said compression compartment being associated with the nip of the rollers on one side of said rollers, pressure cylinder means associated with the top and bottom plates of the compression compartment for swinging the elements of said compartment out of operating position and pressure cylinder means associated with the rollers for pressing the bottom roller against the top roller.
  • lamellas are provided at the sideplates of the compression compartment to seal off said compartment against the rollers when being set in the operating position.
  • a device for crimping groups of textile filaments which comprises a pair of opposing roller means, one roller means being mounted in a stationary manner and the other roller means being swivelably mounted, a compression compartment associated with said pair of roller means for receiving groups'of textile filaments from said roller means, said compression compartment having a swivelable plate adapted to hold the textile filaments back in the compression compartment and to produce an adequate compression force for crimping said filaments in the operating position of said device, said swivelable plate being supported to be swivelable to one side and the remaining portion of the compression compartment being supported to be swivelable to the other side, and operating means associated with the compression compartment for swinging said plate and said remaining portion of said compartment out of the operating position.
  • pressure cylinder means are associated with the swivelable plate and the remaining portion of the compression compartment for making the swivel motion possible.
  • a device for crimping groups of textile filaments which comprises a pair of opposing roller means, one roller means being mounted in a stationary manner and the other roller means being swivelably mounted, a compression compartment associated with said pair of roller means for receiving groups of textile filaments from said roller means, said compression compartment having a swivelable plate adapted to hold the textile filaments back in the compression compartment and to produce an adequate compression force for crimping said filaments in the operating position of said device, operating means associated with the compression compartment for swinging the plate and the remaining portion of said compartment out of the operating position and means including a mechanical quick-action lock for fixing said plate and the remaining portion of said compression compartment in the operating position.
