Definitions

  • the paper strips In the case of conical spools intended for winding fabrics having flared pleats, the paper strips must have the shape of a circular sector, or better still a helical configuration if the fabric has a certain length.
  • strips of this character are not found in the trade it is the chief object of this invention to produce them from elements having rectilinear edges and to provide a device for carrying out this method which is adapted not only to produce this helical strip but also to wind same on a conical spool as an inset to a pleated fabric.
  • This invention is concerned more particularly with a device adapted to be coupled with a pleating machine for example of the type described and illustrated in my United States Patent No. 3,135,443, granted on June 2, 1964.
  • the method of manufacturing the inset strip according to this invention is characterized in principle in that this strip consists of separate elements disposed in succession so as to partially overlap one another with a view to constituting a curved assembly, and that this assembly is displaced in synchronism by pivoting same about its virtual center as a fresh element is added thereto.
  • Each element may be fastened to the preceding one through any known means, for example by gluing.
  • the device for carrying out this method is characterized in principle in that it comprises means for producing the synchronous angular displacement of all said elements.
  • the device comprises a table on which the shaped strip is adapted to travel, and a plurality of frustoconical rollers having convergent axes and driven at the same peripheral linear velocity.
  • FIG. 1 is a perspective view of a device for carrying out the method of this invention
  • Fl G. 2 is a side-elevational view of the same device.
  • FIG. 3 is a plan view seen from above, the upper table of the device being removed.
  • the device for carrying out this method comprises essentially a table formed by platforms T T on which the elements are laid one by one, these elements consisting for example of paper sheets F1, F2 and F3 and tapered rollers R1, R2 tangent to this table having their axes so disposed as to converge toward a point 0. These rollers are driven for continuous rotation at the same peripheral linear velocity.
  • each element will pivot about the vertical axis passing through the point of convergence 0 of the rollers. This pivotal movement permits of disposing each one of these elements askew in relation to the preceding one in order to constitute an assembly having the shape of an annular sector.
  • this assembly may constitute an open annulus or a helical strip Wound in a plurality of superposed turns.
  • the above-describeddevice is coupled with the pleating machine of the tapered presser roller type disposed at the output end thereof.
  • the rollers forming part of the device must converge not only with one another but also toward the same point in space as the rollers Rml and Rm2 of the associated pleating machine which are tangent to each other and have a common generatrix lying in a horizontal plane.
  • the machine and the device of this invention are interconnected by means of an inclined table Tm nearly tangent to the aforementioned common generatrix where by the work can be transferred by gravity and slippage from the pleating machine to the strip-forming device, the latter having thus another function which is to coil up the pleated fabric on a spool.
  • the complete device shown in the drawing comprises on the one hand a frame structure consisting of two vertical sidewalls B1, B2 forming in plan view, in the preferred embodiment illustrated, two parallel polygonal sections inscribed in circles having a common center 0, and one the other hand three tapered converging rollers R1, R2 and R3 journaled in these sidewalls.
  • Rollers R1 and R2 are tangent to platform T1; roller R1 lying below this platform whereas roller R2 lies above it; rollers R2 and R3 are bridged by two platforms T2, T3 which are respectively tangent to their lowermost and their uppermost generat-rices.
  • the device is completed by a tapered idler roller R4 constituting the spool on which the pleated fabric and the inset strip are to be wound.
  • This idler roller R4 is tangent to roller R2 by which it is rotatingly driven and its axis converges with those of the other rollers towards the point 0.
  • Roller R2 is rotated from a motor M, for example by means of a transmission comprising pulleys P1, P2 and a belt C1, the shaft of this roller, which has the pulley P2 keyed thereon, carrying in addition a pair of pulleys P3, P4 transmitting through belts C2 and C3 the rotary motion to the pulleys P5 and P6 of rollers R1 and R2.
  • rollers R2 and R3 overlying the path of the strip revolve in the same direction and at the same speed since they have the same diameter.
  • roller R1 revolves in the opposite direction owing to its position under the platform T1.
  • Each roller R1, R2 and R3 has associated therewith one or a plurality of small counterpressure rollers Rc mounted for loose rotation on a shaft to keep the element or strip in contact with the corresponding main roller.
  • FIG. 3 shows successive positions of this sheet.
  • the lateral edges of the sheet in positions F1, F2, F3 contact the feed rollers R1, R2, R3 along points which lie on an inner circle C1 and an outer circle C2 both centered on the point 0.
  • the roller diameters in the zones of contact must be proportional to the radii of these circles C1, C2 so that not only the axes but also the generatrices of the rollers converge toward point 0 as is likewise apparent from FIG. 3.
  • This geometrical relationship also follows from the fact that point 0 lies on the level of supporting surface T1, T2 in which all the roller generatrices come to lie once per revolution of each roller.
  • the device constituting the subject-matter of this invention is thus adapted not only to produce a curved strip but also to receive pleated fabrics from a conical pleating machine by winding the fabric on a spool in conjunction with an inset strip.
  • a system for interleaving a constantly curved pleated fabric with an inset of like curvature composed of a series of overlappingly assembled rectangular sheets comprising:
  • a pleating machine including a pair of coacting tapered presser rollers adapted to discharge a pleated fabric curved about an imaginery axis;
  • feed means for said sheets including a plurality of driven rollers of tapered configuration tangent to said supporting surface at peripherally spaced locations,
  • presser rollers and driven rollers having axes and generatrices all converging toward a common point on said imaginary axis on the level of said supporting surface
  • windup spool rotatable by said drive means for jointly coiling up a pleated fabric from said presser rollers and an inset consisting of a series of sheets advanced by said driven rollers, said windup spool beingof frustoconical shape substantially converging toward said common point.
  • driven rollers further include a first roller disposed with its axis below said supporting surface, all other driven rollers having their axes above said supporting surface.
