Definitions

  • ABSTRACT The machine is principally constituted by a wheel comprising at its periphery two rows of hammers adapted to overlap one another alternately, each of the hammers of one row being carried by a slide moving transversally on said wheel, means being provided to ensure the alternate pivoting of the hammers, from one row to the other, during the rotation of said wheel in order to provide particularly, by the transversal movement of the slides, the cambering of the thread and the disengagement of said hammers when the thread is cambered,
  • a second device composed of two plates arranged facing one another symmetrically with respect to the direction of advance of the thread and each comprising spiral grooves for the reduction of the pitch of the n'g zag cambered thread.
  • the present invention relates to a machine intended to camber a metallic thread in a plane so as to obtain alternate folds comprising rectilinear parts, substantially parallel, in order to later achieve a known binding in the form of a succession of loops whose extremities are introduced into the aligned perforations of the object to be bound, notebook or other, said loops being then closed to form circular rings.
  • the purpose of the present machine is to allow, in one or two operations, the alternate cambering of the thread in one plane.
  • the first device effects the zig zag cambering, while the second one accentuates it.
  • the machine for effecting the cambering in one plane in a single operation comprising pieces fragile in cambering
  • the description shall apply to that permitting to effect the cambering in two operations, since it comprises a first cambering device having the same characteristics as that allowing to effect the cambering in a single operation.
  • the first device is formed by a wheel comprising at its eriphery two rows of hammers adapted to alternately overlap one another, leaving between them a space substantially equal to the diameter of the thread to be cambered, each of said hammers having edges whose distances separating them from one another determine those which must separate the loops of cambered thread and being articulated on a shaft arranged along the base edge of the active face of said hammer so as to avoid the lamination of the thread, means being provided to ensure the alternate pivoting from one row to the next of the hammers during the rotation of said wheel in order to ensure the cambering of the thread and the disengagement of said hammers when the thread is cambered in zig zag, the latter being taken up by a second device composed of two plates arranged facing each other symmetrically with respect to the direction of advance of the thread and each comprising spiral grooves.
  • FIG. I is a view of elevation of the machine
  • FIG. 2 is a plan view ofFIG. 1;
  • FIG. 3 is a view in elevation, on a larger scale, of the machine limited to the upper part of the periphery of the wheel;
  • FIG. 4 is a plan view of FIG. 3;
  • FIG. 5 is a view in section taken along line V-V of FIG. 3;
  • FIG. 6 is a partial plan view of the machine limited to the spiral plates
  • FIG. 7 is a view in section taken along line VII-VII of FIG.
  • FIG. 8 shows the form of the thread cambered in zig zag by the first devices
  • FIG. 9 shows the form of the thread whose cambering has been accentuated by the second device
  • FIG. 10 shows a binding created from the cambered thread shown in FIG. 9;
  • FIGS. 11 and 12 are views similar to FIGS. 3 and 4 of a device allowing to obtain directly a camber such as that represented in FIG. 9.
  • the first device is constituted by a wheel 1 driven in rotation from a motor 2 by means of a shaft 3 with endless thread 4 meshing with a geared wheel 5 keyed on the shaft of said wheel 1, while the second device is constituted by two plates 6 and 7 driven in rotation in the same direction from, for example, the motor 2 and by means of shafts 3 and 3' having bevel gears 3a and 31;, respectively, fixedly mounted thereon and meshing with bevel gears 3c and 3d, respectively attached to plates 6 and 7, respectively.
  • the wheel 1 turns according to the arrow F 1.
  • the thread 16 is taken up successively from one side and the other by the hammers 8 and 9 whose axes of rotation are staggered on the wheel by a distance equal to one half their width, that is to say that the shaft 10 of a hammer 8 is situated in the middle of the distance separating the shafts of the two hammers 9 adjacent to this hammer 8.
  • the rotation of hammer 8' (FIG. 4) is determined by the ramp 12 against which bears the back 17 of said hammer 8', while that of hammer 9' is determined by the ramp 14 against which bears the back 18 of hammer 9' during the rotation of the wheel, the sudden pivoting of a hammer being prevented until the hammer of the row preceding it has completed its travel, and vice versa.
  • each of the shafts 10 of the hammers 8 is carried by a slide 23 adapted to move transversally in recesses 24 of the wheel 1.
  • the movement of the slides is determined by the ramps 13 and 15 against which their extremities bear.
  • the ramps 13 and 15 are arranged beneath ramps 12 and 14 and extend beyond the extremities of the latter (FIG. 4).
  • the ramp 13 determines the transversal movement of the corresponding slide 23 so as to place the shaft 10 of said hammer in the same alignment as that of the hammers 8 preceding it.
  • ramp 15 moves the slide 23 transversally and in an opposite direction and, in this manner, the hammer 8 in question can pivot freely according to arrow F 2 without its summit laminating the cambered thread 16', which thus allows the pivoting of hammer 9 following it and, consequently, the successive pivoting of all the hammers of the wheel.
  • Recall springs mounted on shafts 10 and 1 I can push the hammers in rotation in the direction of opening.
  • the ramps 12 and 13 have near their outlet a recess 25 allowing the hammers 8 to be subjected to a slight transversal movement, without rotation, controlled by the corresponding slide which moves under the action of a part 15' of ramp 15 arranged to face recess 25, the cambered thread 16' being then freed and received by a tangential paddle 26 on which it can slide to come out of the first cambering device.
  • pivoting shafts of the hammers are arranged along the base edge 27 of their active face.
  • the paddle 26 is extended by a table 28 leading, by means of a second paddle 29, the zig zag cambered thread 16' to between the forementioned plates 6 and 7 forming the second cambering device allowing to reduce the pitch of the thread folded in zig zag.
  • the two plates 6 and 7, whose spread is variable, are each constituted by a right tronconic surface 30, flattened, comprising four grooves 31, 32, 33 and 34 regularly staggered angularly and whose sides are constituted by identical spirals. In this manner the width of the grooves decreases from the periphery of the plate towards it center (FIG. 7).
  • the axes of rotation of the plates 6 and 7 are contained in the plane of the paddle 29 (FIG. 7).
  • the paddle 29 has a trapezoidal contour.
  • a thread guide 35 preceded by a straightening system 36 assures the presentation of the thread before the hammers of the first device in an invariable plane.
  • the driving of the thread according to arrow F 1 is provided, in one part, by the rotation of the wheel 1 determining the closing of the hammers on the thread and, in the other party, by the grooves of plates 6 and 7.
  • a metallic thread cambering machine comprising in combination a wheel, two rows of hammers on the periphery of said wheel adapted to alternately overlap one another and maintaining between them a space substantially equal to the diameter of the thread to be cambered, each of said hammers having edges whose distance separating them from one another determine the distance which must separate the folds of the cambered thread, each of said hammers being articulated on a shaft arranged along the base edge of the active face of same hammers, recall springs connected to said shafts and said wheel and capable of pushing said hammers in rotation in their opening direction, slides connected in rotation to said wheel but mobile transversally, a hammer of one of the two mounted on each slide, two fixed ramps to provide for the alternate pivoting of said hammers, two other fixed ramps beneath the first mentioned ramps to provide the transversal movement of said slides, a first transversal movement, at the inlet of the first two parallel ramps, having the purpose of placing the axis of the corresponding hammer in the
  • a metallic thread cambering machine comprising in combination a first device capable of folding the thread in a zig za and a second device capable of accentuating the camber o the thread, said second device comprising two tronconic rotary plates, with variable spread, arranged facing one another symmetrically with respect to the direction of advance of the thread, the variable angle fonned by the extension of the axes of said plates up to their meeting point being less than the angle at the summit of the truncated cone of each plate, identical spiral grooves on the tronconic face of each of said plates, said grooves being regularly staggered angularly and their width being greater towards the periphery of said plates than towards their center, and a paddle for conveying the zig zag cambered thread, extending radially between said plates and in a plane formed by the axes of said plates.
  • each hammer has a face capable of cambering the thread at the inlet of said first two ramps, said ramps having a configuration so that one of the hammers of one of the two rows is able to pivot, in order to camber the thread, only if the previous hammer of the other row has completed its action on the thread.
  • a metallic thread cambering machine according to claim 1 in which the height of the hammers is considerably greater than the diameter of the thread to be cambered.
