Definitions

  • ABSTRACT Primary Examiner-James Kee Chi Attorney-Holman & Stern [57] ABSTRACT
  • the device comprises a reed in the form of disks mounted on a shaft.
  • the shaft is located in bearings, in the housings of which on either side of the shaft and concentrically therewith there are provided slots accommodating a mechanism to move the weft carrier over the bearing, i.e., outside the shed.
  • This invention can be most advantageously used in travelling wave shedding looms, i.e., looms in which the warp threads form several sheds, each of which accomodates a weft thread carrier.
  • beating up devices comprising a reed in the form of disks with teeth mounted on a shaft placed in bearings.
  • the disks are turned relative to one another so, that their teeth constitute a screw type surface followed by the bevel of the weft carrier (see, for example, USSR Authors Certificate No.25004l cl.86c, 17).
  • An important object of the invention is to provide a device, including a mechanism for moving the weft carrier outside the shed.
  • Another object of the invention is to provide a device, requiring no additional drives, and having a simple design.
  • a beating up device comprising a reed in the form of disks with teeth which are mounted on a shaft placed in bearings, and being turned relative to one another so that their teeth constitute a screw type surface followed by the bevel of the weft carrier, according to the invention, the housing of each bearing on either side of the shaft and concentrically therewith being provided with slots accommodating a mechanism to move the weft carrier outside the shed formed by the warp threads.
  • the mechanism comprises cams mounted on the shaft and located within said slots on both sides of the bearing, the profile of the cams matching with that of-the screw type surface defined by the teeth of the reed disks, and serving to move the weft carrier, while thedistance between the cams does not exceed the bevel length of the weft carrier.
  • Such a design provides for the movement of the weft carrier over the shaft bearing, since the cam profile continues the screw type surface defined by the teeth of the reed disks and serving to move the weft carrier within the shed.
  • the cams are mounted on the same shaft as the disks, no additional drive is required for their rotation.
  • FIG. 1 is a front view of the device according to the invention partly in, longitudinal section;
  • FIG. 2 is a section taken along line II-II in FIG. 1;
  • FIG. 3 is a top view of the device shown in FIG. 1.
  • the device comprises a reed in the form of disks 1 (FIG. 1) with teeth 2,3, and 4 mounted on a drive shaft 5, and a mechanism 6 to move a carrier 7 of weft thread 8 outside the shed formed by the warp threads (not shown in the drawings).
  • Tooth 2 is the widest and shortest tooth, and serves to move carrier 7 in the shed formed by the warp threads. Tooth 3 is a medium tooth, and tooth 4 the highest with, both of these teeth serving to beat up the weft thread 8 to the fell of fabric.
  • the fabric forming process is not described in this application, since it is realized by any conventional method.
  • Carrier 7 is disposed in a recess formed by the short teeth 2 and high teeth 4, and is also retained against dropping out by a channel 10 (FIG. 2) formed in stationary plates 11 which are mounted in the beating up device.
  • Shaft 5 is mounted in bearings 12 (FIG. 1), only one of which is shown in the drawing. Housings 13 of these bearings are provided concentrically with shaft 5 with trajectory of the carrier movement is not interrupted beyond the shed with, the carrier thus freely moving over bearings 12 and passing from one shed into another.
  • shaft 5 is connected in bearing 12 with another shaft '16 to form a single body. Such a connection of the shaft can be repeated many times depending on the loom width.
  • the above-described mechanism enables the weft carrier to pass from one shed into the other without interrupting its trajectory of movement, and providing for adequate laying of the weft thread which is sheared by the with, its ends forming the fabric selvages.
  • a beating up device for a travelling wave shedding loom comprising: bearings; a shaft located in said bearings; a reed defined by disks provided with teeth mounted on said shaft, said disks being turned relative to one another so that their teeth constitute a screw type surface; a weft thread carrier having a bevel whereby this carrier moves along said screw type surface, one of said teeth one of said teeth serving to beat up the weft thread to the fell of the fabric; a housing for each of said bearings, said housing being provided on either side thereof and concentric with said shaft with slots; and means disposed in said slots for moving the weft carrier outside the shed formed by the warp threads over the shaft bearing.
  • the means to move the weft carrier comprises cams mounted on the shaft and located within said slots on either side of the bearing, the profile of the cams matching that of said screw type surface and serving to move the weft carrier, while the distance between said cams does not exceed the length of the carrier bevel.
