BACKGROUND OF THE INVENTION
  The present inventionRespectivelyClaim 1 andClaim 11An apparatus for manufacturing a wire binding member having an arbitrary size and thickness according to the premise ofAnd howAbout.
[0002]
[Prior art]
This type of device is usually used in comb wire binding, in particular the so-called Wire-O.^TM-Used by wire binding (registered trademark) to manufacture a wire binding member used for loosely binding a booklet made up of a plurality of sheet-like prints in a bookbinding apparatus.
[0003]
A Wire-O wire binding member is defined as a wire loop spaced parallel to each other having a loop length L, a loop spacing A, and a wire diameter D, and is formed into a Wire-O ring by a suitable ring closure device. The
[0004]
The wire binding member is typically provided in a stored state for such a bookbinding device to account for different bookbinding requirements regarding loop spacing and loop length, such as booklet thickness and format. An apparatus for manufacturing a wire binding member having different parameters such as a loop interval, a loop length, and the number of loops belongs to the prior art. Conventionally, however, when the parameters change, it is necessary to significantly intervene in the apparatus for manufacturing the wire binding member and change the equipment.
[0005]
From German Patent Application No. 2847700A1, the wire continuously drawn from the stockpile is bent back and forth to be formed into a wavy formation, which is then C-shaped transversely to the wave plane. A method of manufacturing a wire binding for a printing book or the like bent into a shape is known. Since a forming roll having a constant diameter is used for bending, only a wire binding member whose loop interval and loop length are not variable can be manufactured.
[0006]
So-called Wire-O of various sizes^TMBookbinding devices for producing booklets using wire binding members are known, for example, from European patent applications EP0095243 and EP0095245. Similarly, an overview of various bookbinding methods can be found in H.C. Kipphan "Handbuch der Printmedia", page 861 et seq., Springer Verlag Publishing Co. (2000).
[0007]
In this case, the bookbinding apparatus of the above-mentioned patent application is configured to process formed Wire-O wire binding members having various loop intervals and loop lengths.
[0008]
[Problems to be solved by the invention]
In general, in the above-described apparatus, a wire binding member required for binding booklets of different formats and thicknesses is formed in the form of a plurality of already formed binding member reserves, for example, as a roll material or binding. There is a drawback in that it must be provided to the bookbinding device as a member cut to length. In order to be able to bind different formats and thicknesses of booklets in this way, a considerable number of reserves are already required. Moreover, as the format of the booklet to be produced changes, an apparatus suitable for transport and processing can be tailored to the requirements of different wire binding members. Such an equipment change requires costly design of the transport device and bookbinding device, and the bookbinding method becomes economical only when a relatively large number of booklets of the same format and thickness are produced. Thus, a small number of copies is uneconomical and requires a relatively large time cost to adapt the machine.
[0009]
With the means that modern digital printing allows, there is a demand for producing books for individuals or very small copies, such as producing only one copy, in extreme cases called “book on demand” The possibilities are increasing.
[0010]
An apparatus for producing a personal book or individual version in this way is known from US Pat. No. 5,465,213. Kipphan "Handbuch der Printmedia", pages 989, 999 and below, described in Springer Verlag Publishing Co. (2000). For such a small number of copies, it is just necessary to bind the book reliably and at low cost.
[0011]
  Therefore, the object of the present invention is to produce the wire binding member directly according to its demand and directly according to the format and thickness of the booklet to be bound, especially in the bookbinding method, Manufactures wire binding members for different format and thickness booklets bound by comb wire bindingHow andIs to provide a device.
[0012]
[Means for Solving the Problems]
  The object is to claim 1 and claim respectively.2An apparatus of the present invention for manufacturing a wire binding member of any format and thickness having the characteristics described in 1.In placeThis is achieved.
  The apparatus according to the present invention comprises first and second carriages that can reciprocate between a second stationary clamping device and a plurality of sets of transport rolls along the wire transport direction.TheseThe carriage is a means for bending the wire into a wire binding member so that the wire binding member according to the size of the booklet and the thickness of the booklet is manufactured immediately before the bookbinding process according to demand. The means is in particular a at least one first clamping device supported by a second carriage and a bending father rod supported by the first carriage which supports the bending father. ,First 1 Carriage has at least one pinion on the shaft, which pinion is parallel to the rack. 1 Engaging the stationary rack and the parallel rack above the second carriage so that the movement of the carriage causes a movement of the second carriage that is exactly twice as large.It is characterized by that.
  Another device according to the present invention is a first device capable of reciprocating between a second stationary clamp device and a plurality of sets of transport rolls along the wire transport direction. 1 And the second carriage, and these carriages are manufactured so that a wire binding member corresponding to each size of a booklet and a thickness of each booklet is manufactured immediately before the bookbinding process according to demand. Further supporting means for bending the wire into a wire binding member, said means in particular said at least one first support supported by the second carriage. 1 A clamping father and a bending father rod supported by a first carriage that supports the bending father, and the rocker is fixed to the stationary fulcrum. 1 The number on the carriage 1 Are attached so as to be swingable by a second coupler and swingable by a second coupler in the second carriage. 1 The distance between the attachment point and the fulcrum of the coupler is substantially the same.
[0013]
  Of the present inventionMethodIn the case of manufacturing a carpet-like wire, the following steps, that is, the step of supplying the wire from at least one wire reserve to the wire bending device, a flat wire binding member configured in a loop shape, a so-called carpet-like wire The step of bending the wire so as to become and the step of cutting or cutting the wire binding member by the cutting device are performed.
[0014]
The setting of the wire binding member according to the required format or thickness is performed immediately before bending the wire into individual loops. In this case, the parameters for making the shape of the wire binding member, that is, the wire loop spaced in parallel with each other, are the loop length L, the loop interval A, and the number of loops in the binding member.
[0015]
  According to the inventionMethodIn an advantageous embodiment, the loop length and / or the number of loops and / or the loop interval can be arbitrarily selected.
[0016]
In another advantageous embodiment, the wire binding member is matched to the thickness of the booklet by matching the loop length of the wire binding member substantially to the circumference of the corresponding Wire-O wire binding member.
[0017]
In a particularly advantageous embodiment, just before bending the wire loop, the loop length is substantially determined by the distance from the first clamping device, which is fixed just before the wire bend, to the second stationary clamping device. It is decided. At this time, the loop length substantially corresponds to an interval that is half the distance from the first clamping device to the second stationary clamping device.
[0018]
  According to the inventionMethodIn another advantageous embodiment of the present invention, the number of loops of the carpet-like wire is substantially matched to the number of holes in the row of holes provided along the edge of the sheet-like substrate. Match the length of the booklet to be loosely combined with carpet wire.
[0019]
In another advantageous embodiment, instead of a single wire binding that extends over the entire width of the booklet using a single wire binding member, the booklet engages the row of holes at each end and center of the long side. A plurality of wire binding members, in particular three wire binding members are used.
[0020]
In another alternative embodiment, a large number of wire binding members, each having only one loop, are meshed with a row of booklets to be bound. Also in this case, a high bookbinding speed can be achieved by simultaneously engaging a large number of wire binding members.
[0021]
The wire binding member loops are manufactured continuously according to the present invention, and after the loops are repeatedly bent to reach the required number of loops of the wire binding member, the wire binding members are divided into one.
[0022]
In another advantageous development of the device according to the invention, the loop is bent, in particular, until the wire binding member substantially coincides with the hole spacing of the hole rows provided along the edge of the sheet-like substrate. The wire binding members are additionally adapted to the format of the booklet hole sequence by sending the loop spacing by later sending the wire binding members accordingly. At this time, the distance between the two loops can be changed for each loop by appropriately performing the necessary feed after bending.
[0023]
In a particularly advantageous embodiment of the device according to the invention, a reciprocally movable first supporting means for bending the wire into a wire binding member is arranged between the stationary clamping device and the wire supply part along the wire conveying direction. There is one carriage. The wire is bent by sandwiching a wire piece having a length substantially equivalent to twice the loop length between two clamping devices. At this time, the first bending tongue is attached to a second carriage that is operatively connected to the first carriage and that is slidable along a guide portion that extends in parallel with the wire. The working connection between the first and second carriages will travel exactly twice the distance of the first carriage in the same direction as the first carriage moves along the guide of the second carriage. ing. At this time, the bending mold attached to the first carriage advances exactly half the distance traveled by the first clamping device. When the bending dies are mounted substantially in the center of each clamping device, the bending dies substantially move between each clamping device each time they move along the guides by an operative connection between both carriages. Stay in the middle.
[0024]
In another advantageous development of the device according to the invention, the working connection described above is realized by at least one pinion moving on two racks. In this case, the first rack is fixedly fixed to the housing. The first pinion attached to the first carriage engages with the first stationary rack. Similarly, the second rack is attached to a second carriage that engages with the first pinion. Optionally, a second pinion, to which the rotational movement of the first pinion is transmitted via a shaft or other coupling mechanism, engages the second rack.
[0025]
In yet another particularly advantageous development of the device according to the invention, the rocker is fixedly mounted in a swingable manner on the housing of the device and is movably connected to the first carriage via a first coupler. In addition, the second carriage is connected to the second carriage via a second coupler that is movably connected. If the distance between the stationary fulcrum and the attachment point of the first coupler to the rocker is substantially equal to the distance between the attachment points of both couplers to the rocker, then the first carriage A transmission ratio of 1: 2 from the second movement to the second carriage can also be achieved.
[0026]
Different loop length changes are achieved according to the present invention by moving to a new clamping device position while automatically automatically moving to a new center position of the bending pattern at the same time.
[0027]
In an advantageous embodiment of the device according to the invention, the bending tool is substantially centered between the first clamping device and the second stationary clamping device while the first clamping device is in a closing motion. In this case, the center of the wire piece is pushed outward in a direction perpendicular to the closing movement between the clamping devices. At this time, the circular orbit of the bending father pattern is generated by the combined movement of the first carriage and the bending father rod that supports the bending father pattern. In this case, the first carriage is guided in the x direction parallel to the wire feed direction by a suitable guide known to those skilled in the art, and the bent father rod is applied perpendicularly thereto in the y direction. Guidance is provided by a suitable guide known to the traders. In order to obtain an arcuate trajectory of the bend pattern, superimposed movements are carried out, each having a velocity profile that is substantially sinusoidal.
[0028]
In another advantageous development of the device according to the invention, the first carriage is controlled by a known electronic device with at least one motion component, in particular with both motion components including a substantially sinusoidal velocity profile. It is driven by a step motor.
[0029]
In yet another particularly advantageous embodiment of the device according to the invention, the arcuate movement of the bent father rod is effected by a rocker. At this time, advantageously, the rocker with the bent father rod attached to the end is swung around the stationary fulcrum. The movement performed by the attachment points of the rocker and the bending father rod during the rocking movement automatically becomes an arc shape. The movement of the carriage is transmitted in the x direction and the y direction by the guide unit. If the rocker moves at a substantially constant angular velocity, a sinusoidal motion profile of the motion component is naturally obtained as well.
[0030]
The change of the loop length is particularly simple in the development of the device according to the invention by the motor driving a piston which can extend and retract the rocker between the fulcrum and the part to be attached to the bending father type rod. Is achieved quickly and accurately. Thereby, when the wire bending device is in an open state, the length of the wire to be sandwiched is changed, thereby determining the loop length of the carpet wire loop.
[0031]
Otherwise, this approach is particularly advantageous for changing loop lengths because different speed profiles must be calculated or retrieved from the table for each loop length. Moreover, the step motor never achieves the circular motion that is possible by cam control.
[0032]
When the bending mold reaches the final bending position, it is raised vertically to allow the wire binding member to be fed. Accordingly, it is possible to prevent deformation and friction that may occur on the flat surface of the wire binding member when the bending die is retracted. In addition, the vertical lifting of the bending father requires only a small amount of force and takes a short time.
[0033]
In a further advantageous development of the device according to the invention, the wire is stamped laterally in the closed state of the bending device after being bent in order to allow the wire binding member to be fed, The bending father is lifted. This advantageously helps to form the loop during the bending process and reduces the springback of the bent wire.
[0034]
In a further development of the device according to the invention, the bending tool is additionally crimped to the wire by means of a spring when bending. Thereby, the wire segment to be bent is continuously pulled with a substantially constant spring force during the bending process, which has an advantageous effect on the shaping of the bending process.
[0035]
In a further advantageous embodiment of the device according to the invention, the cutting device is arranged immediately after the second stationary clamping device. Particularly advantageously, the cutting device is arranged inside the second stationary clamping device. At this time, the cutting device is configured to cut a piece of wire and drop the piece through a second stationary clamping device. Thereby, the wire is held firmly firmly while being separated, thereby obtaining a smooth cutting edge. This is particularly desirable to reduce the risk of injury.
[0036]
In an advantageous development of the invention, a precise cutting of the wire after the required number of loops has been achieved is that the lever for actuating the cutting cutter abuts via a pulley, in particular a cam disc, In particular, it is realized by swinging inward by energization of the electromagnet.
[0037]
In order to further improve the shaping of the loop, an advantageous development of the device according to the invention is such that at least one of the bending tool and / or the clamping device comprises a lug that is pushed into the inner radius of the bending site when bending. To be constructed. The use of such lugs when bending the wire is known from the prior art.
[0038]
There are several advantages to producing booklets of different sizes and thicknesses depending on the comb wire binding. Fully automatic wire binding member for binding booklets with arbitrary loop length L, width A, and preferably wire diameter D, with the number of loops corresponding to the maximum booklet length to be processed The production of the formula is possible. There is no need to change equipment or adapt equipment for manufacturing wire binding members. In particular, the deformation of the wire binding member manufactured to meet the demand is likely to be able to greatly shorten the wire binding member conveyance path from the apparatus to the subsequent processing portion of the wire binding member by automatic manufacturing. Therefore, the probability of failure is greatly reduced as compared with the conventional apparatus. Thereby, wire binding members for booklets, in particular in extremely extreme cases, only a small number of copies, for individual booklets and books, are manufactured flexibly and quickly at low cost. It is possible.
[0039]
In this case, the parameters relating to the loop interval and loop length are detected by the apparatus according to the present invention through the sensor device, and the format and thickness of the booklet to be bound and the type of perforation are determined and transmitted to the control unit. And / or sent from the aforementioned device or user to the control unit.
[0040]
In the second step, the manufacturing parameters for the wire binding member are determined by the control unit, and in the third step, the wire binding member is manufactured by electronically or mechanically connected devices.
[0041]

FIG. 5 shows a comb-like bookbinding made of, for example, a plurality of wire binding members 41 'in multiple loops spaced apart from each other so that the holes 12 remain open. Other combinations of the above-described schemes will be apparent to those skilled in the art.
[0045]
As shown in FIG. 6, a wire storage unit 20 including wire storage rolls 21, 22 and 23 each having a wire 1 having different wire diameters (for example, diameters from 0.8 mm to 1.2 mm) is provided. In this case, for example, a wire that can be distinguished by different coloring and can be assigned to the aforementioned wire diameter is used.
[0046]
A pair of unillustrated sets known to those skilled in the art that are driven by motors from the individual wire storage rolls 21 to 23 by means of grips 21 ', 22', 23 'attached to each storage roll. It can be transported to a transport device 30 composed of a transport roll. Another set of three conveying rollers 3 corresponding to the prior art, arranged after the conveying device 30 and each conveying roll being slightly offset from each other, mechanically pulls the wire or directs the wire Play the role of attaching. Instead of three wire storage rolls, it is also possible to use only one wire storage roll 22 with a diameter of 1 mm, as shown in FIG. 7, for all the booklet types to be bound. Included in the category.
[0047]
As shown in FIG. 2, in order to manufacture a wire binding member 41, 41 ′, 41 ″, which is also called a carpet-like wire 41 ″, a first reciprocating motion along the wire transport track 2 or in the X direction is possible. The wire bending device 40 shown in FIGS. 1 and 7 to 11, which is constituted by a carriage 43, is used. For this purpose, two guides 44, 44 ′ arranged in the housing of the device 40 are provided, on which the first carriage 43 is supported so that it can slide along the wire direction 2.
[0048]
The carriage 43 supports a second carriage 43 ′ supported so as to be slidable in parallel with the wire direction 2 by at least one guide portion 44 ″, 44 ′ ″ attached to the first carriage 43. ing. Similarly, the bending father rod 46 is disposed on the first carriage 43 by the guide portion 46 ′, and the bending father rod 46 moves in a direction perpendicular to the wire direction 2 called Y in FIG. It has come to be.
[0049]
The second carriage 43 ′ supports a first clamping device 42 that can sandwich the wire 1. The first clamping device 42 is opened and closed by a cam or an electromagnet (not shown) well known to those skilled in the art. The second carriage 43 'operates independently of the first clamping device 42 and supports a feed clamping device 50 that is opened and closed by a cam or electromagnet (not shown) well known to those skilled in the art.
[0050]
The bending father mold rod 46 supports a bending father mold 42 ″ shown in an enlarged manner in FIG. The bending mold 42 ″ is supported by the two swing levers 71, 71 ′ so as to be swingable. The swing levers 71, 71 ′ are connected by a rod 72, and the forward movement of the rod 72 caused by the rod 70 supported by spring action causes the bending pattern 42 ″ to enter the bending pattern rod 46. It is designed to cause a dive. By the swing levers 71 and 71 ′, the position of the bending mold is kept parallel from the inwardly swinging state to the outwardly swinging state. The rod 70 is initially stressed by a spring 73 in order to press the bending mold 42 ″ to the wire 1 with a constant force during the wire bending process. This initial stress is adjusted by a screw (not shown) well known to those skilled in the art that is rotatably mounted within the spring housing 74 and presses the spring 73.
[0051]
The second clamping device 42 'is fixedly attached to the housing and is opened and closed by a cam or electromagnet (not shown) well known to those skilled in the art.
[0052]
In the first embodiment shown in FIG. 7, the first carriage 43 is driven by a step motor (not shown) connected to a shaft 48 supported inside the carriage, thereby rotating the shaft 48. Motion can be transferred by two pinions 48 ′ and 48 ″ from a rod 45 placed stationary on the housing of the device 40 to a rack 47 movably placed on the carriage and mounted on the second carriage 43 ′. It is.
[0053]
In an alternative embodiment, the pinion 48 ′ engages both racks 45, 47. Thereby, the movement of the first carriage 43 along the x direction is transmitted to the second carriage with a double value.
[0054]
FIG. 8 illustrates an alternative apparatus for performing linked motion. A rocker 52 is swingably attached to the stationary fulcrum 55. The rocker 52 is attached to the first carriage 43 at a mounting point 51 so as to be swingable by a coupler 53, and is also capable of swinging at a second mounting point 51 ′ so as to be swingable by a coupler 54. 43 '. At this time, the interval between the fulcrum 55 and the attachment point 51 on the first carriage 43 is the same as the interval between the attachment points 51 and 51 ′ of the couplers 53 and 54 on the first carriage 43 and the second carriage 43 ′. Substantially equal. When the first carriage 43 moves in this embodiment, the second carriage is linearly moved along the guide portions 44 ″, 44 ′ ″ by the double amount through the couplers 53, 54 and the rocker 52. Move.
[0055]
In order to manufacture the wire binding member 41 or the carpet wire 41 ″ with the apparatus of the present invention based on the embodiment shown in FIGS. 8 and 9, the bending father rod 46 having the bending father die 42 ″ A sinusoidal movement, which is achieved by corresponding control of the stepping motor 49 by the control device 100, must be performed in the Y direction.
[0056]
An alternative advantageous embodiment is shown in FIGS. Next, the function of this apparatus when a wire loop is bent will be described with reference to these drawings. This embodiment is characterized by including a rocker 60 supported so as to be swingable about a swing point 62. The rocker 60 is extended by a piston 63 that reaches the rocker 60. The piston 63 is movably supported in the longitudinal direction of the rocker by a spindle (not shown) which is well known to those skilled in the art and is inside the rocker 60. The position of the piston 63 can be changed by an electric motor 61 with a rocker 60 attached to the other end, or in the housing in a stationary manner, and the movement of the piston 63 via a joint (not shown) well known to those skilled in the art. It can be obtained by the electric motor 61 transmitted to.
[0057]
The piston is pivotally attached to the bending father rod 46 at the other end. When the wire bending device 40 is in the open position, the piston 63 extends, so that the first carriage 43 slides in the X direction. At this time, the second carriage 43 also moves through the motion connection from FIG. The two racks and pinions shown in FIG. 11 or the rocker shown in FIG. Thereby the bending mold 42 "always remains in the middle between the first clamping device 42 and the second stationary clamping device 42 '. That is, the loop length L of the wire loop S can be changed by extending or contracting a part of the piston 63 protruding from the rocker 60.
[0058]
To manufacture the wire binding members 41, 41 ′, 41 ″, the wire is inserted into the clamping devices 42, 42 ′ and the bending mold 42 ″ and the electronic control device 100 is operated to be electromagnetized or the prior art. The clamping device is closed with a cam (not shown) according to the above, i.e. the wire 1 is locked in the area 1 'between the clamping devices 42, 42'.
[0059]
When in the initial position, the bending mold 42 ″ is positioned exactly in the middle between the clamping devices 42, 42 ′ (see FIG. 9), and the distance between the clamping devices 42, 42 ′ is always at this time. It is twice the loop length L (see FIG. 2). That is, for the booklet formats to be manufactured from DIN A3 to DIN A5, these lengths are values obtained by adding about 2 mm depending on the bending radius of the wire to 2 × 25-80 mm, respectively.
[0060]
FIG. 10 shows a wire bending device 40 that is being bent in the closing process. Due to the rotational movement of the rocker 60, the bent father rod 46 is fed with a sinusoidal velocity profile along the guide portion 46 'of the bent father rod 46, and at this time, the sandwiched wire piece 1' is moved forward. Pressed. At the same time, the circular movement of the attachment point between the piston 63 and the bent father rod 46 causes the carriage 43 to move to the left with a sinusoidal velocity profile along the guide portions 44, 44 ′ of the first carriage 43. Cause exercise. At the same time, the second carriage 43 ′ moves with the clamping device 42 in the same way to the left with a double value sinusoidal velocity profile. At this time, the wire is also pulled out from the stockpiling rolls 21, 22 and 23 accordingly.
[0061]
Due to the connection of the movement, the bending mold 42 "remains in the exact center between the clamping devices 42, 42 '. The spring 73 is pressed against the wire piece 1 ′ with a constant force by the spring 73, whereby the wire is pulled with a constant force between the clamping points of the clamping devices 42, 42 ′.
[0062]
FIG. 11 shows the device after bending is complete. As can be seen in the enlarged view of the bending mold 42 '', the bending mold 42 '' has two lugs 80 for embossing the wire 1 'at the bending portion so that the spring back after bending is almost eliminated. Has on the side. The clamping device 42, 42 'has a lug which is known from the prior art, preferably comparable. In order to prevent springback of the leg of the loop, the wire is additionally stamped with a device not shown which is well known to those skilled in the art.
[0063]
After the loop S is completely bent, the wire 1 is locked by the feed clamp device 50 and subsequently the clamp devices 42, 42 '' are opened. By the swing lever 71, the bending mold 42 "swings inward from the loop S into the bending pattern rod. Since the bending master die 96 (see FIG. 13) of the second stationary clamping device 42 'is lowered downward, the feeding to the loop S becomes free. Next, the feed clamp device moves forward in the wire direction 2 by the loop interval A, the second stationary clamp device 42 ′ re-locks the wire 1, the feed clamp device 50 opens, and the first carriage 43 Then, the second carriage 43 ′ returns to the initial position, and the production of the next loop S is started. Before the next loop S is produced, the loop length L is set by the piston 63, whereby the loop geometry can be newly adjusted. Advantageously, this readjustment takes place during the backward movement of the rocker 60 so that the next loop can be produced without time loss.
[0064]
In another embodiment, the movement is started by turning on a step motor 49 controlled by a sinusoidal waveform, except that the course of the individual movements for bending the wire loop S is not affected thereby and is described above. It is according to the progress.
[0065]
According to the method of the present invention, a constant loop spacing A of 12 mm is advantageous for DIN A3 to DIN A5 to be manufactured and all corresponding US booklet formats. However, it is also included in the scope of the present invention that parameters such as the loop interval A and the loop length L can be freely selected.
[0066]
When the number of loops N set by the electronic control unit 110 corresponding to the maximum size to be bound is reached, the wire binding members 41 and 41 ′ are processed by the wire cutting machine 90 shown in FIGS. , 41 ″ are divided one by one.
[0067]
FIG. 13 shows a side view of the wire cutting device 90 together with the clamping device 42 ′, in which the housing cover is omitted for the sake of clarity. The clamp device 42 ′ presses the wire 1 against the mother die 96. This matrix 96 has a lug 96 '. Two springs (not shown) in a spring shaft 97 ′ in the housing of the cutting device 90 press the master 96 together with a lug 96 ′ against a stopper (not shown), and these stoppers are movably supported. The cam disk or the like can be pressed downward against the spring, thereby causing the master 96 to sink into the housing of the cutting device 90. As a result, the mold 96 is taken out of the path, and the loop S can be sent after the wire 1 'is bent.
