Definitions

  • My invention refers to lcalendering machines and more especially to the elastic rolls forming part of such machines. It is an object of my invention to provide such rolls I with a covering which renders them more eiicient than those hitherto in use.
  • the covering of elastic rolls for calendering machines as hitherto designed is formed by separate discs made of paper, fabric or lo Wedding, these discs being forced upon the core of the roll by pressure.
  • ig. 1 is an end elevation of the roll
  • Fig. 2 is a perspectivev illustration showing the band or ribbon partly unwound from its re.
  • a is the core and b is the covering.
  • this covering 7L is the warp of the spiral or serpentine ribbon or band
  • i is the wft which is shown as differin in length radially, the single weft 40 threa s bein larranged in staggered-relation.
  • the distance c shows the thickness of the la .er which is gradually worn down,whi1e the 'stance d shows that part of the roll which remains over.
  • the part c is formed almost entirely of weft threads z' and contains only as many warp threads as are required in order to hold the weft together.
  • the warp h and the staggered -weft threads 0 are distributed as required for a Vuniform thickl0 ness of the fabric. All fibres constituting the weft threads extend in spirally wound threads radially to the axis of the core.
  • the surface of a roll composed as hereinbefore described is of uniform hardness on il its entire circumference and, owing to all the fibres havin the same direction, also uniform elasticity, w ich is increased by the fact that the fibres stand on edge.
  • the covering is less sensitive to knots and creases, as all the libres o0 have the tendency of rising directly after having been compressed.
  • the life of a roll constituted in accordance with this invention is also lengthened in consequence of the radial arrangement of the libres.
  • the pressure exerted upon the roll by the counter roll enters the covering down to a certain depth. When in operation the coverin is permanently movin down to this dept
  • the spirally wound bres are more resistive against this constant movement.A
  • the rolls manufactured according to the present invention oier the advantage that the warp threads h in the inner portion d may be made I5 of an inferior material as compared with the warp threads in the outer portion c.
  • a -roll for calendering machines comprising a core and a band or ribbon wound about said core standing on edge, the weft 86 threads in said band or ribbon-being arranged in staggered relation.
  • a roll for calendering machines comprising a core and al band or ribbon 'wound about said core standing on edge, the; weft threads in said band or ribbon differing in length.
  • a roll for calendering machines comprising a core and a band or ribbon wound about said core standing on edge, the weft threads in said band or ribbon extending to various depths in radial direction.
  • a roll for oalendering machines com-4 prising a core and a band or ribbon wound about said core standing on edge, the number of the weft threads in the outer portion of saidroll being in excess of their number in the inner portion.
