Definitions

  • the invention relates to manual folding machines for large plans and documents.
  • the plans are folded according to a standard which means that, after folding, the document notably has a format of 210 mm x 297 mm.
  • pressers whose role is to tighten the paper and compress the folds made, are recalled by pressure by an exhaust device and springs, when a folding blade finishes engaging the paper under the presser concerned.
  • the primary object of the present invention is to suppress the noise in question. Furthermore, in the system mentioned in connection with current machines, the need to make the abrupt closure of the presser coincide exactly with the arrival at the end of the blade stroke means that, in addition to the large number of parts of the mechanism, this-izici obliges adjustment operations whose time spent on them increases the cost price and involves the risk of subsequent adjustment requiring maintenance operations during use.
  • a second object of the present invention is a simplification of manufacture thanks to the reduced number of parts of the proposed mechanism as well as the elimination of adjustments in manufacture and as maintenance operations.
  • the machine for bending planes comprising swivel arms of blade carriers with opposite blades which can be moved back and forth to alternately form the folds of a plane engaged between them against surfaces of folding and abutment with which the pressing members for forming and maintaining the folds cooperate
  • the folding and abutment surfaces are constituted by two half-tables mounted to oscillate around axes parallel to the pivot axes of the support arms blades and integral with levers subjected to the action of cams integral with said pivot axes of the arms and arranged so that a half-table presses the plane or any fold formed in its place against the corresponding pressing members, while the other remains free to oscillate upon introduction between it and the corresponding pressing members of the blade and of the corresponding plane fold to be formed.
  • the machine according to the invention is characterized in that the pressing members are mounted floating and biased by springs towards the folding and abutment surfaces of each half-table, and further also that the pressing members are provided with normal support crutches on spacing chairs with respect to the corresponding half-table, said crutches being actuable upon erasure by said blades when each fold is formed.
  • the machine shown comprises a casing in the lateral flanges 1 of which are rotatably mounted, parallel to one another, two axes 2, 36 whose ends carry, integral with them, two pairs of pivoting arms 11, 27.
  • L one of the pairs 27 longer than the other is connected by an operating handle tube 26.
  • Each of the pairs of arms 11, 27 is also respectively braced above the casing by a tube carrying a folding blade, 12 for the arms 11 and 25 for the arms 27.
  • two half-tables 17, 20 In a central upper opening of the casing are arranged two half-tables 17, 20 forming folding surfaces and stop for the planes to be folded as will be seen below.
  • cams are also integral with respective levers 3a, 37a, the lever 3a carrying a hinge pin 6 of a latch 39 which has a coupling notch with a connecting finger 32 carried by the lever 37a, so that in the state of coupling of these levers, the two arms blade holders can be operated together using the operating handle 26.
  • An unlocking lever 33 is articulated in the housing around an axis 33a, the individual support of which is not shown here, and it is provided with a central axis 38 of articulation of two levers 8, 30, the free ends of which are in the form of a fork and cooperate with fingers 7, 31 secured to the levers 5, 34 for controlling the half-tables.
  • the lever 33 extends projecting from the casing to be maneuverable at will by the user.
  • the pressure members 14, 23 extending above them cooperate and which are shaped as curved blades facing the half-tables and their vertical abutment rim and inserted floating between supports 13, 13a and 24, 24a formed along the upper opening of the casing.
  • These pressing members 14, 23 are respectively provided at their ends, around axes 14a, 23a which they carry, of articulated crutches 15, 22 of support cooperating with chairs 16,21 attached to the internal wall of the flanges 1 of the casing.
  • tension springs 10, 28 furthermore fixed on axes 9, 29 supported by the flanges 1 and also forming operating stops for the corresponding blade-holder arms 11, 27.
  • the springs 10 and 28 are intended to keep the pressers 14 and 23 in constant abutment with the vertical edge of the half-tables 17 and 20, which guarantees their correct positioning. These springs also serve to bring the pressers down to ensure the initial formation of the fold and after that prevent the paper from escaping during the reverse movement of the blade.
  • the end of the document to be folded can then be introduced between the front presser 23 and the corresponding half-table 20.
  • the lever 33 is then raised manually by the operator so that, as illustrated in FIG. 4, the axis central 38 raises the levers 8 and 30 which, pushing the fingers 7 and 31, separate the levers 5, 34 for controlling the half-tables, which has the effect of raising them around their axis of oscillation.
  • the half-table 20 therefore coincides with the end of the document which has been engaged between it and the presser 23.
  • This same movement guarantees the establishment of the abovementioned initial position of the pressers 14 and 23, in that 'it brings, by pressing the half-tables against the pressers, the crutches 15 and 22 to be effectively wedged on the chairs 16 and 21 as shown.
  • the blade-carrying arm 27 with an operating handle 26 is then pushed backwards.
  • the cam 37 which is integral therewith then comes to bear on the roller 35 and the lever 34, which has the effect of keeping the half-table 20 well pressed against the corresponding presser 23, thus preventing the corresponding end of the plane of slide.
  • the lever 33 is released by the user, which allows the rear half-table 17 to lower, and thus save the space necessary for the introduction of the blade 25 when it comes push the document between the presser 14 and this rear half-table 17, at the end of the movement of the blade-holder arm 27 towards the rear. As illustrated in FIG.
  • the front blade-holder arm 27 is brought back by the user towards it, and it drives in its return movement with it the rear blade-holder arm 11.
  • the half-table 17 is in turn raised by the cam 3 which pushes the lever 5-for controlling the half-table 17 via the roller 4 , so that the half-table 17 is in its turn strongly applied against the presser 14 against which it thus maintains and tightens the fold which has just been established.
  • the accumulation of thickness of the successive folds of the document called to be formed is absorbed by the inherent elasticity of the half-tables.
  • auxiliary means intended in part to allow control or command at the foot of the machine further facilitating its control with both hands by the user.
  • This additional system is constituted by means of a cam 40 mounted to rotate freely around the pivot axis 36 and provided with a return spring 42, interposed between it and the axis 36, while a cable 41 connects this cam 40 to a foot control pedal not shown.
