Definitions

  • the present invention relates to a thread guiding roller, and more particularly to a roller for conveying a plurality of substantially parallel synthetic threads through the successive treatments required in the manufacture thereof.
  • a large number of such wet threads are guided in parallel around one or more rollers in each of the treating zones, each roller being manufactured from materials that are resistant to the treatment liquids. See, for example, the rollers in U. S. Patent 2,674,113.
  • roller When-the roller is constructed in one unit, it must be relatively long in order to accommodate a large number of parallel threads, and in case of breakage or damage, the entire roller must be replaced, which is an expensive operation.
  • One way to overcome this disadvantage has been to use a number of narrow rollers corresponding to the number of threads to be conveyed, each of the rollers being mounted on a common shaft and separated from each other by spacer plates or collars.
  • part of the set must be dismantled in order to remove and replace the damaged roller.
  • a thread guiding roller which is constructed of a cylindrical core on which are mounted a plurality of spacer plates or collars having circumferential grooves on each side thereof, and between each pair of collars are assembled metallic sheets bent to conform to the shape of the metallic core and providing thread guiding surfaces.
  • Figure 1 is a longitudinal sectional view of a preferred form of roller showing a series of spaced collars retaining the sheets constituting the thread guiding surfaces in position, one of said collars being axially displaced from engagement with the adjacent sheet for the purpose of illustration;
  • Figure 2 is a view in transverse section taken on line 2-2 of Figure l;
  • Figure 3 shows a detail of a portion of one sheet constituting the thread guiding surface which is provided with undulations extending in an axial direction of the roller.
  • the numeral generally indicates the roller which consists of a core 11 having a series of grooves 12 running longitudinally thereof for accommodating projections 13 formed in spacer plates or collars 14 when they are mounted on the core 11 by sliding the collars axially thereof.
  • each collar 14 On each side of each collar 14 there is formed a circumferential groove 15, and between each pair of collars 14 a strip of sheet material 16 is retained in the adjacent grooves after it has been bent to conform to the shape of the core 11.
  • the roller is assembled by sliding a collar 14 into a 2,728,446 Patented Dec. 27, 1955 predetermined position on the core 11 and then bending the sheet material 16 so that it will fit into the groove 15 on one side of the collar and the sheet is retained in position by sliding a second collar 14 longitudinally of the roller until the other edge of the sheet engages the adjacent groove of the second collar. This same operation is repeated until the required number of sheets constituting thread guiding surfaces have been arranged in position between the collars.
  • Any known type of fastening or stop member can be mounted on each end of the roller after all the collars and sheets have been clamped in position, whereby the whole roller will function as a rigid unitary unit.
  • the sheet material When the undulations run in an axial or longitudinal direction of the roller, the sheet material may also be formed in the shape of a flat V in transverse section as shown in Figure 1.
  • This V shape makes it possible for the excess liquid to be guided to the sides of the sheet by the centrifugal force created by the rotation of the roller.
  • the liquid forms at the sides it can be removed readily by means of stripping guides positioned on the adjacent collars.
  • the core of the roller may be solid, but it is preferable that it be hollow, particularly in cases where the roller is of large diameter and it is required to rotate at high speeds.
  • the grooves in the core for receiving the projections on the interior surfaces of the collars may be constructed of the same material from which the core is manufactured. It is also possible to use a smooth core with a lining in which the grooves are provided. In this way a roller resistant to the chemical influences to which it is subjected can be manufactured in a simple manner.
  • the lining may, for example, be manufactured from soft rubber or other chemically resistant material.
  • the strips of sheet material that constitute the thread guiding surfaces can be manufactured from any desired material provided it is sufficiently resistant'to the chemicals with which it comes in contact.
  • a thread guiding roller comprising a cylindrical core, a plurality of spaced, individual collars circumferentially grooved on each side thereof, said collars being individually, axially movable of the core, means for preventing rotational movement of each of said collars with respect to said core comprising a projection on one of said members and a complementary recess therefor on the other said member, corrosive resistant, flexible, metallic sheets held in the form of hollow cylinders by engagement of each sheet in adjacent grooves between each pair of collars whereby any sheet may be removed transversely of the axis of the core at will by axial movement of the necessary collars.
  • a thread guiding roller according to claim 1 in which said means comprise a series of longitudinal grooves in said core and a series of projections in said collars.
  • a thread guiding roller according to claim 1 in which the sheets. are provided with undulations running parallel to the axis of the roller and having the shape of a fiat V in a direction transverse to the axis of the roller.
