Definitions

  • Fabric expanding devices i. e. devices for stretching fabrics widthwise, consisting of a plurality of expanding or spreading rollers turnably arranged in the manner of an are on a curved shaft are already known.
  • Figure 1 is a view of the expanding device, and Fig. 2
  • FIG. 1 is an enlarged cross section of a portion of one of the roller sections 4, showing the undulations.
  • a constructional example of my clevice is illustrated in Fig. 1 of the drawings.
  • the generally somewhat damp fabric which may also be dry in some cascs,runs without being subjected to widtl'iwise stretching stresses but with a certain longitudinal tension on the concave side of the first expanding roller and contacts completely and without forming hollow spaces 3 with the circumferential face as it is so to speak suck-ed against said face by the longitudinal tension and by capillary action.
  • adhesion surface increased by the corrw 84,690, and in Switzerland February 23, 1925.
  • a fabric stretching roller having a curved shaft and a plin'ality of stretching roller sections loosely mounted on said shaft,
  • a fabric stretching roller having a curved shaft and a plurality of stretching roller sections mounted on said shaft, the surfaces of which sections are an undulating curve the crests and hollowsof which curve being substantially equal as regards extent in the axial and radial directions.
