Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closure wire band cartridge for a closure forming and driving machine.

Conventionally, various devices have been devised for driving the closure, but in such devices, it is necessary to form the closure in advance. So, is there a closed wire connected to the molding device? A closing metal forming/driving machine has been proposed which supplies fF, forms a closing metal from a closing metal wire using a forming/driving device, and drives the closing metal.

SUMMARY OF THE INVENTION An object of the present invention is to provide a closed metal wire band cartridge for a closed metal forming and driving machine that can reliably supply the closing metal wire to the forming and driving device of such a closed metal forming and driving machine.

In order to achieve this object, in the present invention, a closing pin is formed from a closing metal wire by a forming driving device attached to a fixed member, and a closing metal forming driving machine for driving the closing metal has a forming driving device. A cartridge for supplying a closed metal wire band through an opening provided in the fixing member, which is connected to a housing for accommodating the closed metal wire band and an outlet of the housing, and whose feeding surface is flush with the lower surface of the opening. a feed gutter, a protrusion provided at the tip of the feed gutter and inserted into the opening 1; and an upper presser protruding from the above-mentioned forming driving device side, and when the leading closing metal 4-karat gold of the closing metal nail metal band mentioned above protrudes from the opening toward the above-mentioned forming driving device side, The upward movement of the gold band is restricted by the above-mentioned -L section presser.

1 to 4 show a closed metal wire band car 1- according to the present invention.
It is a figure which shows the closing metal forming driving machine to which a ridge is to be attached. As shown in the figure, the closure molding and driving machine IO has one pedestal 20 attached to one closure head 30. As shown, the closure head 30 has one base 3
2 and one upright front part 34. its base 3
2 is welded or otherwise firmly attached at its rear end to an upright z2 extending upwardly from the base 20. This mounting of the closure head 30 is shown by way of example only, and other methods of mounting the closure head 30 in fixed relationship with the base 20 may be used. A front frame 40 is attached to the closure head 30 by a retainer spring 50 for vertical movement in relation to the closure head. Each end of the hold-down spring 50 is bent inwardly and has a respective inwardly projecting leg 52 passing through a respective hole 54 on the opposite side of the front frame 40 . Its respective legs 52 project slightly toward each other a sufficient length to engage behind the rearward end 36 of the forward section 34 of the closure head 30. Two protrusions 38 extending laterally on both sides of the closure head 30 fit into two U-shaped notches on both sides of the front frame 40.

The four spacer protrusions 33 that are integrally formed with the front part 34 of the closure head 30 and extend forward are respectively positioned against the inner surface 46 of the front frame 40 and the front part 34 of the closure head 30. 34 and are in contact to maintain a constant spacing.

A long rectangular RFH port 44 is located in the center of the front frame 40,
It receives the protrusion 62 of the forming block 60. The presser spring 50 has a generally V-shaped portion 5 bent downward.
6, and its V-shaped portion 56 presses against the outer surface of the molding block 60 as shown in FIG.
0 is held in that position by a spring force.

In the gap between the closure head 30 and the front frame 40 created by the spacer protrusion 33, there is a former 70 and a driver 80 for forming a closure from a short piece of wire.
There is. The former 70 rests against the inner surface of the front frame 40 and is located between two vertically extending slide rails 48 extending inwardly from the front frame 40 towards the closure head 30. . The two slide rails 48 can be stamped or otherwise formed from the same material as the front frame 40. The molding machine 70 is generally U-shaped and has two legs 72 extending downward;
It is usually thicker than the upper part 74 of the. The outer surface 76 of the leg 72 abuts the adjacent opposing surface 47 of the slide rail 48. Former 70 is narrowed at its upper end at central member 74, thereby creating two laterally projecting upwardly directed shoulders 78. A central member 74 is cut from the material of the former 70 and has a prong 75 bent to extend rearwardly through an elongated opening in the driver.

To explain FIG. 5, the driving tool 80 has a driving blade 8.
It has two bushings 84 on the sides separated from each other by two cuts from 6. The bushing 84 is slightly bent along a line 89 to extend forward and contact the inner surface 46 of the front frame 40 . Both ends 85 of the bushing 84 are thus adapted to engage respective ones of the two upwardly facing shoulders 78 of the former 70 . The outer portions of the two terminals 85 are adapted to engage and engage beveled cam surfaces 49 of the slide rail 48, with the cam surfaces 49 facing toward the respective outer portions of the terminals 85. There is.

Each of the two legs 72 of the former 70 has a recess 79 immediately below its two upwardly facing shoulders 78 . Each leg 72 also has a respective groove 77 along its inwardly facing end, each groove 77 together forming a passage to facilitate shaping and driving the closure. ing.

Both outer ends 87 of the driving blade 86 are convex so as to fit into the concave cross-section of the passage forming the groove 77.

In addition to the four spacer protrusions 33, the front part 34 of the closure head 30 has two forwardly projecting coupling guiding protrusions 35 located on either side of the driver 80, thereby ensuring that the driver 80 is vertically aligned. It helps guide this during directional movement. These parts are separated from the front section 34, which is not shown but is shown in FIGS. 5 and 6. It will be seen that the opposite outer ends 83 of the driver 80 slide into engagement with the inner surfaces of each of the two guide projections 35.

Extending rearwardly from the inner surface 46 of the front frame 40 are two control projections 43 that control the upward movement of the former as it returns to its original position. and is adapted to engage with the upper end 81 of the former 70.

The two control projections 43 also lightly contact the front surface of the driver 80 so that the driver 80 does not budge during operation.

The document closer is constructed to accept a cartridge 90 having a housing 92, only a portion of which is shown (see FIG. 9). The housing 92 accommodates a closed wire band 94 in which closed wires 200 are attached to each other to form a band shape, and is wound into a roll, and a feed gutter 96 is connected to the outlet of the housing 92. has been done. As shown in FIGS. 1 and 4, the feed trough 96 has four laterally projecting lateral projections that engage the lower surface of the inner projection 37 that projects inwardly from the base 32 of the closure head 30. It has a protrusion 98. Due to the engagement between the side protrusion 98 and the inner protrusion 37, the outlet 10 of the feed gutter 96 is
2 and the opening 100 in the anterior part 34 of the obturator head 30 is ensured. Although not shown, the housing 92 and closure head 30 can be connected to each other by a suitable coupling method.
are combined.

The feed claw plate 1 is attached inside the front part 34.
04, the feed pawl plate 104 has two protrusions 106 protruding laterally, each of which is loosely fitted into two holes 108 in the front part 34 (FIGS. 2 and 9). (see figure). This feed pawl plate 104 has two holding members 110, one on each side. The feed spring 112 made of spring fR passes through two holes 114 in the feed spring 112 and two corresponding holes 118 near the bottom of each of the two holding members 110 of the feed claw plate 104. It is attached to the feed claw plate 104 by two rivets hl16. Two holding members 110
In between, there is a driving claw 120 extending downward slightly forward of the holding member 110. In the assembled state of each component shown in FIG.
and actuates the feed spring 11.2 to feed the closing wire 200 as explained below. There are two pawls 121 at the tip of the sending spring 112, and these pawls are in contact with the closing wire 200 of the closing wire band 94, as shown in FIG.

Reverse feed control board 1 is loosely attached to feed @96.
22, this reverse feed control plate 122 has two protrusions 12.
4 is held in that position almost solely by its weight, and its two holding claws 126 rest on the closing metal wire 200 of the closing metal band 94. A rear end 128 of the reverse feed control plate 122 is in contact with a portion of the housing 92 to prevent the closing wire 200 from moving backward toward the cartridge 90.

The upper end 130 of the driving tool 80 is held within a driving grip 132 and a return spring 134 is mounted between the driving grip 132 and a rearwardly extending flange 138 that is integral with the forward portion 34. has been done. Return spring 13
4 applies upward pressure to both the grip 132 and the upper end 130 of the driver 8o in the opposite direction to the direction indicated by the arrow 140 in FIG.

The base 20 has one anvil 21 attached to its upper surface, and the anvil 21 has two bending grooves 23 corresponding to the driving blades 86.

At the beginning of the cycle of operation, the return spring 134 is at its fullest extension and the driving handle 132, like the driving tool 80, is at its uppermost position as shown in FIG. The first closing wire 200 is a molded block 60
It is located in a groove 64 in a protrusion 62 of. The former 70 is at its top and its two ends 81 are connected to the control projection 4.
It engages with the bottom surface of 3. The protruding piece 75 extending rearward of the forming machine 70 is in a state of approaching or contacting the drive claw 120 of the feed claw plate 104 in the area shown as 1.3 in FIG. .

When the driving grip 132 is actuated quickly downward, the closing wire 200 is formed and driven, while the feed spring 112 and the feed pawl 121 move the next closing wire 200 into the groove 6.
The state is now ready for supplying to 4. When the driving grip 132 is returned to its original position, the parts quickly return to their original positions as described above and as shown in FIG. 64.

More specifically, its operation is as follows.

1. When the handle 132 is initially depressed, the driver 80 moves downward in the direction of arrow 140. Probably only 0.0
Almost immediately after the 01 inch back and forth movement, the lower ends 85 of both driver legs 84 of the driver 80 come into contact with the two -L facing shoulders 78 of the former 7o.

As the driving tool 80 continues its movement due to the force applied by the grip 132, the forming tool 70 is also moved downward in the same manner.

As soon as the forming machine 70 begins to move downward, the protruding piece 75 begins to move rearward along the diagonal cam surface of the drive pawl 120, and also moves the drive pawl 120 around its axis of rotation 108 by a spring. Start moving backward while resisting 112.

2. Through the leg 84 of the driver 80, the leg 72 of the former 7o almost immediately after the former begins to move downwards due to the force applied thereto by the driver 8o.
The downward ends of the molding block 6o come into contact with both ends of the closing wire 200 held in the groove 64 of the molding block 6o.

3. When the forming device 7o is further moved downward driven by the driving device 80, the closing wire 200, which was joined together by other methods such as adhesive or tape, is removed.
The terminals on both sides of the closing wire 200 begin to be separated from the band 94. At the same time, both legs 72 of the former 70 begin to bend the opposite ends of the closing wire 200 downward.

4. Closing Clasp 4 The force applied to both ends of the metal 200 through the legs 72 of the molding device 70 is resisted by the pressure applied by the molding block 60, the front frame 40, and the spring 50. Therefore, both ends of the closing wire 200 are smoothly and continuously bent downward by the downward movement of the former legs 72.

While this movement is taking place, the bent leg of the closure is fitted into the groove 77 of the leg 72 of the former 70. Immediately after the closure is formed into its U-shape, the curved portion of the former 70 or its end comes into contact with the upper surface 63 of the protrusion 62 of the forming block 60. Driving tool 8
As the former continues its downward movement due to the force applied to it by the force applied to it by the
Push 0 downward in the same way. Since the molded block 60 is fitted into the opening 44 of the front frame 40,
The front frame 40 is moved downward together with the forming block 60. During this movement, both ends 52 of the retainer spring 50 move downwardly along the rear end 36 of the closure head 30. However, with this configuration, the resistance applied to the downward movement by the presser spring 50 is not large, and it is difficult to hold the open molding block 60 for molding the closure and the front frame 40 in their respective upper positions. It may or may not be sufficient. This depends, to a large extent, on the strength of the closure wire 200 and its rigidity. It depends, in part, on how tightly the closure wire 200 is connected to the next successive closure wire 200 in the band 94.

Therefore, both ends of the closing wire 200 are bent by the force applied by the former legs 72. This force is transmitted to the forming block 60 and the front frame 40, and the closing wire 200 placed on the anvil 21 is bent. 300 and front frame 40 are not likely to occur, if at all, before these two are pushed down until they come into contact. Depending on the interaction of various frictional forces, this downward movement of the forming block 60 and the front frame 4o is caused by the closing wire 2
This can even happen before the ends of 00 have actually been bent yet. Alternatively, since the frictional force increases when both ends of the closing wire fit into the grooves 77 formed in the holding leg portion 72, the closing wire 200 may be bent while the both ends of the closing wire 200 are being bent. It might happen. Alternatively, the curvature 73 may not come into contact with the surface 63 of the molding block 60 until after the closure has been molded (as is usually the case).

At the rear, during the downward movement of the former 70, the projection piece 75
passes along the cam surface 142 of the drive pawl 120 and over the bend 144 to the flat portion 136. Once the end protrusion 75 reaches the flat portion 136, no further rearward movement and movement of the drive pawl 120 into the ready state occurs, but rather the ready state is maintained. The action of preparing the drive claw for operation by the pressure of the protruding piece 75 is performed by the driving leg 84 of the driving tool 80.
must occur before contacting the two cams 49 at the upper ends of the sliding grooves 48, as will be explained below. If this arming operation is not completed by the time the bottom end 85 of the leg 84 reaches the two cams 49, the drive tool 120 must be used to ensure arming of the drive pawl 120 as described. Former 7 by 80
Not enough pressure applied to 0. This rearward movement of the drive pawl 120 causes it to move further rearwardly to the retaining member 11.
It is transmitted to the feed pawl 121 that rests on the band 94 consisting of the zero and closed wires 200. This backward momentum is only approximately 2 times the thickness of one closed wire 200.
Since it is less than double the amount, it is extremely small. This retracted position is maintained until the grip 132 is released from the applied force, as explained below. During this backward movement of the drive pawl 120, the reverse feed control plate 122 ensures that the band 94 does not move back and thus the feed pawl 121 grasps the other closed wire 200 rearward from its previous position. ensure that the

However, if there is an interaction of various frictional forces as described above, and the front frame 40 comes into contact with the closing object 300 before the former 70 completes its downward movement; Once the front frame 40 contacts the object to be closed 300, the former 70 continues its downward movement forming the entire closed wire 200 until the bottom end of the leg 72 also strikes the object to be closed 300. Slide down along both sides of the closure. 30 where both ends of the leg portion 72 are closed
Just before coming into contact with 0, the bottom ends 85 of the driving tool legs 84 begin to move upwardly along the cam 49, and the legs 84 move backwards against the natural spring pressure created by their fold line 89. move to. As a result, the leg portion 84 is released from engagement with the upwardly facing Ji 178, and the leg portion 7
It slides along the surface 79 of 2 while feeling some resistance.

The thickness of the leg 72 in the region of the surface 79 is equal to the thickness of the sliding groove 48.
Since the thickness of the driving tool leg 84 is the same as that of the sliding groove 4,
8, while the former leg 7
2 remains in contact with surface 79 of 2.

In this way, former 70 completes the last small portion of its downward movement until it contacts closure 300.

6. Furthermore, the driving tool 80 is attached to the bottom end 85 of the driving tool leg 84.
Continuing the downward movement with the former causes the former leg 72 to remain in contact with the closure 300 while the driver leg 84 moves downwardly along the surface 79 and the channel or ridge 48. go. Forming machine 7 with driving tool 80 stopped

located at or relatively close to the bottom of the Now, the driving tool 80 moves downward and the projection piece 7 stops.
5, the notch 82 moves downward. During this movement, the bottom end 180 of the driver 80 strikes the beveled upper limit 66 of the forming block 60, thus pushing the forming block 60 outwardly and in a restrained manner in relation to the front frame 40. The spring 50 is pressed down against the pressure of the central portion 56. This releases the previously molded closure from the molding block 60. However, both legs of the closure are still attached to the former legs 72.
remains in the passageway 77 formed by.

7. As soon as the forming block 60 begins to move outward, the bottom end 180 of the driver 80 passes that point;
The head of the already formed closure is struck and the formed closure is driven downward through the thing to be closed, at which point it is bent in a known manner by the folding groove 23 in the anvil 21. During this final driving of the closure, a passageway 77 guides the closure and drive tool 80.

8. When the lower part is completed, the front frame 40
and former foot 72 rests on the closed in its lowermost position, while driving tool 80 rests on top of the already driven closure. Operating grip] 32
Upon release of the applied force, actuation spring 134 forces actuation handle 132 upwardly in a direction opposite to that indicated by arrow 140 . This upward movement of actuating handle 132 lifts driver 80 with it.

During the upward movement of the driver 80, the notch 82 therein also moves upwardly in relation to the prong 75y of the former 70. When the bottom end of the notch 82 engages the projection piece 75, the force exerted by the actuating spring 134 causes the driving tool 80 to move further upwards, / while also pushing up the forming tool 70 with it. At the point when the driving tool 80 and the forming tool 70 begin to move in one direction, the front frame 40 and the forming block 60 similarly begin to move upward. The specific point at which front frame 40 and forming block 60 begin to move in one direction is determined by the interaction of various frictional forces. Furthermore, due to the frictional anastomosis between the driver leg 84 and the surface 79 of the former leg 72 and the frictional anastomosis between the driver 80 and the passage 77, the former
Although the projection piece 75 is still located at the upper end of the notch 82, it will begin to move upward simultaneously with the upward movement of the driver 80. Driving device 80, forming device 70
It is not important in what order the forming block roller 0 and the front frame 40 start their upward movement, or whether they start their movement in one direction at the same time. In fact, because the frictional forces are different, the components 9, such as the front frame 40 and the forming block 60, temporarily stop moving when they start moving in one direction. 1lffi
What is important is that all parts are returned to their original positions and that all parts are designed and adapted to each other to achieve this purpose, as shown. For example, if the former 70 continues its movement in one direction together with the driving tool 80, it will eventually be stopped by a frictional force, or its upper end 81 will be connected to the control projection 43 in the front frame 40. If the front frame 40 has not already been returned to its original position by the hold-down spring 50, then a further continued upward movement will also move the front frame 40, but in the latter case: The control protrusion 43 captures the upward movement to continue further,
The upward movement of the driver 80 also causes the notch 82 to move upwardly in relation to the projection piece 75 of the former 70. On the other hand, if the frictional force is sufficient to capture the upward movement of the former before the former reaches its uppermost peak, then the driver 80
The upward movement of the notch 82 causes the bottom end of the notch 82 to
The notch 82 is moved upward in relation to the protruding piece 75 until it engages with the protruding piece 75.

At that time, the further upward movement of the driver 80 also causes the forming tool 70 to move upward.

9. At the point of upward movement of the driver 80,
The driver leg 72 is connected to the guide ridge or guideway 48.
At the two ends, the driver 80 passes through the cam surface 49 from below and as soon as the former 70 is captured by frictional force or by the control projection 43, the driver 80 engages the former 70. The notch 82 begins to move upward in relation to the protruding piece 75,
The driver legs 84 also move along and corresponding to the surface 79 of the former 70 until they pass upwardly over the shoulder 78 and return to their original position relative to the inner surface of the front frame 40. and move upward. Because the driver 80 is spring steel, the driver leg 84 returns to its original position as shown in FIG.
It will be seen that it is located above with a very small gap.

]0. The driving tool 80 reaches the projection piece 75 of the former 70 and the end 81 of the former 70 is inserted into the control projection 43 of the front frame 40.
When pressed against , all upward movement of all parts is eventually stopped completely. Immediately before reaching this point, the protruding piece 75 moves along the inclined part 142 of the drive pawl 120.
It moves to the flat part 131, but at that time, the feed pawl 121 inserts the unformed closing wire 2 into the groove 64 in the forming plotter 60.
00, and the driving tool 80 opens the opening 44 in the front frame 40.
When the molding block 60 passes from the bottom to the top, the molding block 60 returns to its normal position inside a little before that.

Below, when the margin closing wire 200 is fed into the groove 64 of the forming block 60, the end of the closing wire 200 restricts its movement,
) 1464 in the vicinity of the sliding groove 48 (see FIG. 5). The feeding of the closing wire 200 to the forming block 60 is such that when the leading closing wire 200 first contacts the former member 70 and is separated from the band 94, that portion of the downward driving motion is actuated. This is the same as when the closing gold wire 200 car is not pressed against the forming block 60 during the process.

This sequence of operations prevents movement of the closing wire 200 at this point in the driving movement from going in an undesired direction.

Most of all of the parts of the closing die forming and driving machine shown in Figures 1 to 13 are identical, and like parts have been given the same reference numerals. The biggest difference between the closing metal forming driving machine 400 and the machine 10 is that the machine 400 has the first
In the machine 10 shown in FIGS.
It is operated by one electric solenoid 402, usually located where the solenoid is located. solenoid 40

or the like, to hold the solenoid 402 in a fixed position. The driver 80 has an armature 406 at its upper end 130 that extends through a solenoid 402 .

Therefore, when the solenoid 402 is actuated by the switch SW1, the armature 406 is driven downward, and the driving tool 130 is driven down to form and drive the closing metal. Spring 134 is housed within armature 406 to keep the design compact.

The solenoid 402 is connected by a conductor 408 to a suitable electrical circuit C (one of which is the actuation switch SWI)6 the circuit C is in turn connected by a conductor 409 (one of which is the activation switch SWI). (with an on/off switch SW2) connected to a power supply S, for example an AC power supply. Circuit C is of a well-known conventional design and therefore will not be described in detail here. One suitable circuit is disclosed in U.S. Pat. No. 3,971.969, issued July 27, 1976.

In addition to the several differences mentioned above, namely the use of the solenoid 402, the closure molding and driving machine 400 also features a presser spring 5.
Both ends 410 of 0 are two oval holes 4 in the front frame 40.
12 through the vertical member 3 of the closure head or frame 30
The difference is that they fit tightly into the two holes 44 on both sides of 4. Figures 14 to 1
The oval hole 412 in the front frame 40 of the machine shown in FIG. The only difference is the location. In this position, the ends 410 of the hold-down spring 50 engage the ends 410 of the vertical member 34 of the closure head 30, instead of engaging after the ends 36 of the vertical member 34 of the closure head 30, as seen in the machine 10. They fit into the respective holes 414. It will be seen that with this arrangement, the ends 410 of the hold-down spring 50 no longer slide up and down along the rear end 36 of the vertical member 34 as seen in the machines shown in FIGS. 1-13. Therefore, unlike the machines shown in FIGS. 1-13, the front frame 40 of the electrically operated machine 400 does not move downwardly toward the closed object 300 during operation.

Rather, the nq-way stopper frame 40 remains stationary in relation to the closure head 30 throughout all of the normal operating stages of the machine 400.

It will be recalled that during operation of the machine shown in FIGS. 1 to 13, the legs 72 of the former 70 cooperate with the forming block 60 to form a closure from an unformed closure Φ1 gold 200. Probably. Additionally, after forming the closure, the curved portion or end 73 of the former 70 extending between the legs 72 is removed from the forming block 60 as shown in FIG.
It will be recalled that the molding block 60 and the front frame 40 are pressed down until the front frame 40 reaches the thing to be closed 300. In machine 400, former frame 70 must be modified because front frame 40 is held stationary against downward movement. Thus, as shown in FIG. 16, the only difference between the former 470 shown therein and the former 70 shown in FIGS. 2.5 and 6 is that the former 470 of FIG. The curved portion or end 473 of is located higher than the end 73 of the former 70 . That is, the distance from the bottom end of both legs 72 in FIG. 7
This is greater than the distance to 3. Thus, during operation of the device, the legs 472 form a closure from the closure wire 200, while the legs 472 and the ends 473 form the closure block 6.
It continues its movement until it touches the closed object 300 without reaching or touching 0.

Two bushings 84 of the driving tool and the recess 7 of the forming tool 70
9 is closed. When the entire molding stage is completed, the molder 70 together with the legs 72 continue to transport and guide the molded closure downwards towards the object to be closed 300 by frictional anastomosis with the end 85. It is formed and balanced.

Except as stated in the immediately preceding paragraph, the operation of the machine shown in FIGS. 14 to 16 is similar in all essential respects to the operation of the machine shown in FIGS. 1 to 13. It's the same.

1, both ends 52, 410 of the presser spring 50 are fitted into oval holes 54, 412 in the front frame 40. Because the front frame 40 is fitted into the holes 54 and 412, the front frame 40 is fixed to the closure head 3.
It will move outward a small distance from 0, but that distance is between the oval holes 54 and 412, respectively, and the ends 52 and 410.
is determined by its relationship with the diameter of This degree of ellipse is determined by the front frame 40 in order to eliminate the closure wire that has not been formed into a normal shape or the closure wire that has not been formed so that the front frame 40 can close the device. Therefore, to unblock a machine, all that is required is to operate the five machines in rapid succession until the jam returns to normal. By doing so, the hold down spring 50 will force the front frame 40 back into position in relation to the fixed closure head 30.

FIGS. 17 to 22 are diagrams showing a complete closing molding and driving machine equipped with a closing plate side plate cartridge according to the present invention. As shown in the figure, the feed spring 112 has two rivets.
It is coupled to the holding member 110 by. Holding member 1
10 swings about the shaft 502 by a support portion rotatably attached to the shaft 502. Since the drive claw 120 is integrally constructed with the holding member 110, the two feed claws 121 are driven by the feed spring 112.

A housing 92 houses a closed wire band 94.

A feed gutter 503 connected to one outlet of the housing 92 is attached, and the feed gutter 503 has a base plate 504, a base side wall 506, and two side protrusions attached to the outside of the base plate 504. The upper surface, that is, the feeding surface is the opening 1
It is on the same plane as the lower surface of 00. The rear ends 511 of the two guide pieces hold down the reverse feed control plate. The front frame 40 has eight spacer protrusions 512 and 51 each consisting of two spacer protrusions in one set.
3.514 and 516. Cartridge 90 is held in its operative position by spring 517.

Cartridge 90 is then seated in its lower position within closure head 30 by spring 517, also shown in dotted lines, as shown in dotted lines in FIG. Next, as shown in FIG.
8 passes through the opening 100 and reaches the front frame 40.
12 and is pushed to the left. The width of the opening 100 is considerably longer than the length of the closing metal 200. Projection 5
08 is located between the spacer protrusions 514 and 516, and a part of the upper presser 509 provided in the feed gutter 503 parallel to the feed surface also passes through the opening 0100 of the closure head 30,
It protrudes into the space between the head 30 and the front frame 40. As the band 94 is advanced into the forming block 60, the leading closing wire 200 contacts the two spacer projections 514 and is properly positioned within the forming block 60.

To explain FIG. 21, the first closing gold wire 200
It can be seen that when the molding block 60 is fed into the molding block 60, both ends of the molding block 60 extend under the two two-part pressers 509, respectively. The upper presser foot 509 is the top closing wire 2
00 protrudes into the gap between the closure head 30 and the front frame 40, the driving blade 86 and the former 70 operate upward to close the closure wire 2 at the head of the closure wire band 94.
It functions to prevent 00 from being pushed upward. In this manner, protrusion 508, upper retainer 509, and aperture 100 cooperate among themselves to guide and hold cartridge 90 in place.

It can also be seen that the closing wire 200 is prevented from being bent, distorted, or dislodged from the closing wire band 94 during the upward movement of the driving blade 86 and former 70.

The two upper pressers 509 located within the opening 100 form part of the edge that defines the exit through which the leading closing wire 200 is fed out of the cartridge 90 and enters the forming block 60.

As explained above, in the closed wire band cartridge for the closed all-forming driving machine according to the present invention, it is possible to reliably supply the closed wire band to the forming driving device of the closed all-forming driving machine. Thus, the effects of the present invention are significant.
