Description

  The present invention relates to a mold set for molding dumplings or dumpling shaped food, a compression apparatus used for compression of such a mold set, and a dumpling molding machine having such a mold set and compression apparatus.

  Today, food manufacturers are constantly using molding machines to aid in the production of dumplings in order to increase productivity. In most cases, currently used dumpling forming machines are configured to form dumplings in the successive steps described below. In the first step, a dough, a mixture of flour and water, is passed through one or more roll mills into a sheet to form a dough sheet of the desired quality and thickness. In the next step, after driving a die cutter having a cross section of a predetermined geometric shape such as a circle or an ellipse to cut the dough sheet, thereby cutting out a dough pad of a shape matching the above cross section The dough pad is dropped and flattened onto a molded part placed under the cutter and having the same number as the dough pad. In the last step, each dough pad that has been transported on the mold set and has received the filling is folded over the filling during the closing action of each molding, so that the dumplings are D-shaped or semi-circular It is first molded into a shape (hereinafter referred to as “D-shaped or semi-circular semi-finished product” of dumplings). The entire process described above is also described in Patent Document 1 entitled “Gyoza Molding Method and Apparatus” filed on August 20, 2009 by the present applicant.

  In the following steps, a manual process is required to turn the D-shaped or semi-circular semi-finished product into the desired shape of a typical handmade dumpling. Normally, following the above-described method, dumplings are manually molded, and in such manual molding, the operator can enlarge the entire arcuate ridge (hereinafter referred to as the “top”) of the dumpling semi-finished product as much as possible with both hands. Put your finger between your thumb and forefinger and close the wrists so that both wrists face each other, so that the gyoza filling pocket (hereinafter also referred to as “filling pocket” or “pocket”) is sandwiched between your fingers Compress using the palm side surface and part of both palms. After such compaction, the final dumpling product is not a D-shaped or semi-circular semi-finished product, but is shaped into an actual handmade dumpling shape, i.e., typically shaped like a scallop or curved triangle. The Also, after such compression, the filling pocket is made smaller and more juicy by shrinking the filling pocket to better satisfy people's taste and appetite. It should be understood that a variety of shapes still exists due to the particular compression of each individual worker. However, compressing the filling pocket in the manner described above is still common to all handmade dumplings.

Chinese Patent Application No. 200910168437.7

  However, in the prior art, machines that can still play the above-described compression process still manually by the operator and can play the role of man in the final shaping of any handmade dumplings have been developed to date. There wasn't. According to statistics, an average of 5-6 professional workers currently working together with a continuous production molding machine is required, which is a major limitation on the further improvement of industrial productivity. Yes.

  In order to achieve the final goal of fully automatic molding of dumplings or dumpling shaped foods, the present invention is a mold set comprising a pair of jaws so as to cover the filling by closing the pair of jaws. Clamp the dough pad, thereby forming a dumpling or dumpling shaped food semi-finished product, with the closed jaw in the plane defined by the jaw, the filling pocket for the dumpling or dumpling shaped food inward from the top A mold set is provided that is driven to mimic the movement of a compressing person. After such compression, the dumplings or dumpling shaped food semi-finished product changes from D-shaped or semi-circular to a shape resembling real handmade dumplings, the filling in the pocket is dense and juicy, Satisfy your taste further. The mold set is adapted to finally replace the person's role in the production of traditional dumplings or dumpling shaped foods, so that productivity is greatly increased and labor costs are greatly reduced.

  The invention also drives the jaws of the mold set in a closed state to mimic the movement of a person compressing the filling pocket of the dumpling or dumpling shaped food inward from the top in a plane defined by the jaws. A compression device is provided.

  The present invention also provides a dumpling forming machine provided with at least one mold set and the same number of the compression devices.

  The objects, features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

1 is a schematic diagram showing an overall system including a forming pallet and various guide rails according to the present invention. It is an enlarged view of the A section of FIG. 1 which expands and shows the shaping | molding pallet 100 by this invention. FIG. 6 is a perspective view showing two mold sets according to the present invention in a molding pallet and each transmission mechanism for driving the jaws of each mold set. 1 is a perspective view showing a four-bar link device according to the present invention and a connector attached to connect them. FIG. 1 is an overall perspective view of a molding pallet according to the present invention. It is a whole perspective view of a forming pallet which shows a four bar type link device and a connector attached to these.

  First, it should be noted that in the description of the present invention, the term “dough” or “flour and water mixture” means a soft and thick mixture of dry material and liquid. The dry material is, for example, flour or meal, and the liquid is, for example, water, milk and / or oil, and such a mixture makes a raw material for food, in particular a dumpling or dumpling shaped food. For this reason, it is kneaded, molded, or cooked.

  In addition, the “gyoza or gyoza-shaped food” used herein refers not only to traditional Chinese gyoza, but also foods similar to other gyoza such as Japanese gyoza, piroxy and ravioli. Generally speaking, any machine or method intended to replace the person's role in the formation of dumplings or dumpling shaped foods, i.e. to mimic human movement, compresses the filling pockets of dumplings or dumpling shaped foods As long as a movable mold set that mimics the movement of a person is used, the present invention falls within the scope of seeking protection.

  For ease of explanation, the opposing edges of the dough pads that are stuck together to form an arcuate ridge are referred to herein as a semi-finished or finished product of a dumpling or dumpling shaped food. Called “top”. Further, the swollen portion of the dumpling or dumpling shaped food that holds the filling is referred to as “pocket” or “filling pocket” in the present specification. Thus, whether in the form of a semi-finished product or in the form of the final product, the dumpling has a filling pocket bulging in the center and an arcuate top around the edges of the filling pocket.

  In this specification, the directional terms "front", "back", "left", "right", "up" and "down" directions refer to the selected reference system shown by the subject of the present invention in the accompanying drawings. It should be understood that it is only used to indicate a particular direction arranged in the direction. Accordingly, the direction referred to for a particular such system is not used to improperly limit the invention, but only for ease of explanation. In other words, any understanding of the present invention should not be limited by a particular reference frame selected for ease of explanation.

  In the embodiment shown in FIGS. 2 to 4, the molding pallet 100 includes at least one mold set 10, the same number of transmission mechanisms 20, a lower pan 30, and a base frame 50 from top to bottom. have. Each mold set 10 has a pair of jaws 11 and 12 that are symmetrical to each other. When the pair of jaws 11, 12 are placed flat, the mold set 10 opens upward and the contour of the mold set matches the contour of the dough pad. Since a standard fabric pad is circular or oval, at least in this embodiment, the contour of each mold set 10 appears circular or oval when it is wide open. Of course, if necessary, the mold set 10 may be designed to have other shapes (eg, diamonds or rectangles). The molding pallet 100 may include only one mold set, or may include three or more mold sets.

  Referring to FIGS. 5 and 6, each mold set 10 has a saucer 35 in addition to the jaws 11 and 12, and the saucer 35 is configured to be used with the jaws 11 and 12. Collects the fabric pad cut out from the fabric sheet by one of the die cutters. In the molding process, when the molding pallet 100 is guided along a predetermined path or sequentially positioned at different positions, the jaws 11, 12 are driven to close them gradually like a bivalve so that the filling is Clamp the stuffed dough pad to form a D-shaped or semi-circular dumpling or semi-finished product of dumpling-shaped food.

  In the embodiment shown in FIGS. 2 to 4, the jaws 11 and 12 are preferably formed of a flexible material such as rubber or elastomer, and the transmission mechanism via connectors 40 a and 40 b such as pins, bolts, and pegs. 20. In this embodiment, the connectors 40a, 40b are exemplary pins, and the upper end of each pin is embedded in the jaws 11, 12 from below, so that each jaw swings the transmission mechanism 20. It is attached to the member 22b (described later). As a result, each of the jaws 11 and 12 can move within a predetermined range together with the swing member 22b in a plane defined by the jaws 11 and 12. The plane defined by the jaws is a virtual plane in which the D-shaped or semicircular contour of each jaw is formed. As shown in FIG. 3, the plane defined by the jaw 11 is a virtual plane on which the D-shaped or semicircular contour of the jaw 11 is formed, and the plane defined by the jaw 12 is the D-shaped or semicircular of the jaw 12. This is a virtual plane on which the outline of the image is formed. In a state where the mold set 10 is opened flat or completely closed, the plane defined by the jaws 11 overlaps the plane defined by the jaws 12. That is, in this state, the pair of jaws 11, 12 produces only one plane by themselves.

  In the embodiment shown in FIGS. 3 to 6, the transmission mechanism 20 is, for example, a four-bar link device. In the four-bar link device, each connector 40 a has a V-shaped member 22 of the link device. The lower end of the pierce is secured to one of the wing plates 34, which is the lateral part of the lower pan. When a force is applied from the outside, the four-bar link device is deformed, and each V-shaped member 22 rotates about the corresponding connector 40a. As a result, the swing arm 22b of each V-shaped member 22 functions to move the jaws 11 and 12 via the connecting portion of the connector 40b. In this embodiment, each oscillating arm 22b of the V-shaped member 22 functions as a oscillating member of the transmission mechanism 20, operates the jaws 11 and 12 in a closed state, and moves toward the filling pocket for dumplings. The compression movement like

  2 to 5, when the jaws 11 and 12 are closed, the recesses 13 are formed on the surfaces of the jaws 11 and 12 that come into contact with the dumplings or the dumpling-shaped food dough. In the form of a wedge-shaped notch or other type of groove. When the swinging member 22b of the transmission mechanism 20 swings inward within the plane defined by each jaw, the jaws tend to bend at the respective positions where the recesses 13 are formed, thus Bending points and outer folds are formed similar to the bending points and outer folds formed when the finger is bent. With the jaws 11 and 12 closed, the bends and the outer folds leave an indentation on the dumpling or dumpling shaped dough, similar to the indentation left by the actual human finger, thereby Appearance of handmade products that can better satisfy people's aesthetic preference for traditional handmade dumplings.

  Each jaw 11, 12 preferably has a large elasticity that can reliably return to the home position consistent with the original uncompressed state following each compression. To help achieve this goal, a spring 14 is provided on each jaw. In the embodiment shown in FIG. 4, the spring 14 is illustratively a torsion metal embedded in each jaw. It should be understood that other forms of springs may be used in place of the spring 14, such as metal bars, coil springs or leaf springs. The spring 14 passes through each end of the pins 40a, 40b so that the elasticity of the spring 14 is applied directly to the four bar linkage 20 via the pins 40a, 40b in order to fully draw out its elasticity. It is good to be configured as follows. With such a structure, the lifetime of each of the flexible material jaws 11 and 12 is greatly extended. Alternatively, the spring 14 may be located somewhere outside the jaws, for example on a member directly connected to the jaws, such as a four bar linkage. This solution will be described later.

  In the embodiment shown in FIG. 4, the four-bar link device 20 is, as an example, a rod hinge mechanism constituted by two linear arms 21 and two V-shaped members 22. One end of the arm 21 is hinged in a V shape by a pivoting portion to which a cam roller 23 is attached, and the other end of each linear arm 21 is hinged to the side arm 22a of each V-shaped member 22. It is connected. Since they are connected in this way, the two linear arms 21 and the two side arms 22a of the V-shaped member 22 are configured to form a quasi-parallelogram mechanism.

  Up to this point, the swing arm 22b of each V-shaped member 22 functions as a swing member of each four-bar link device 20 so as to act on the jaws 11 and 12 via the connecting portions of the connectors 40a and 40b. Said. 4-6, each connector 40a extends through the top of one V-shaped member 22 and is then secured to one of the wing plates 34 so that each V-shaped member 22 corresponds thereto. It can be rotated around the connector 40a. In such a structure, the four-bar link device 20 transmits power via parallelogram deformation, thereby filling the pair of jaws 11 and 12 with dumplings or dumpling-shaped food as the operator does. Drive to cause the movement to compress the pocket. More specifically, when a force is applied to the four-bar type link device 20 via the cam roller 23, the link device 20 is forcibly deformed, thereby causing the swing arm 22b to move within a plane defined by the jaws. Operate to swing within range. When the four-bar link device 20 is pressed so as to have a stubborn shape with the jaws 11 and 12 closed, the swinging member 22b pivots about each connector 40a and the mold set 10 By swinging inward to the inside, the jaws 11 and 12 in a closed state are contracted inward in a plane defined by both jaws 11 and 12 like an Ω shape or a C shape. The dumplings thus compressed are shaped like scallops.

  The connector 40a may be repositioned some distance away from the top of each V-shaped member 22 and somewhere along the side arm 22a to mimic other human compression forms. In this case, an additional connector 40b must be secured in the same position as the pin 40a is moved, so that the portion of each jaw corresponding to the top of the V-shaped member 22 is above the V-shaped member 22. It remains installed in the same place. With this configuration, the entire swing arm 22b and a part of the side arm 22a of each V-shaped member 22 are moved as a single swing member so that the jaws 11 and 12 move. It is possible to contribute. When actuated in this manner, the closed jaws 11, 12 contract to form a substantially curved V-shape. The gyoza or gyoza-shaped food compressed in this way has a tendency to have a curved triangular shape.

  Further, the side arm 22b of each V-shaped member 22 preferably has a shape corresponding to the shape of the jaw, and the shape is, for example, from a linear shape (see FIG. 3) shown in FIG. 3 to an arc (not shown). It is in the range until it becomes. This change is intended to adjust the angular direction in which each jaw is driven to compress the filling pocket of the dumplings or dumpling shaped food to improve the effect achieved by compression and hence the appearance. Yes.

  In addition to what has already been shown in FIGS. 3 and 5, further recesses 13 are formed in the jaws 11 and 12 to more closely resemble the actual person's finger bends and folds. The final appearance should be able to resemble the real thing, like that of an actual handmade product. Still, the recesses 13 of each jaw can be configured to alternate. That is, in the closed state, each pair of recesses in the jaws do not overlap each other, so for dumplings or dumpling shaped foods, alternating indentations similar to the indentations left on the actual handmade product due to alternate finger joints Is formed.

  As described above, the four-bar link device 20 may be provided with a spring 14 that assists in returning each jaw to its home position consistent with the original uncompressed state. As an example (not shown), the spring 14 may be a coil spring configured to connect two opposing hinge pins 24 (see FIG. 4) in each four-bar link device 20. When the spring 14 is biased by a force that deforms the four-bar linkage 20, the spring 14 is pulled or compressed, and energy is stored in the spring 14. As the deforming force weakens and eventually disappears, at the same time, the spring 14 releases energy, thereby driving each jaw associated with the four-bar linkage 20 in the opposite direction to its home. Return to position. Obviously, if the spring 14 is provided in the four-bar linkage 20, the spring 14 simplifies the jaw construction and assists the jaws returning home after each jaw contraction.

  In the above-described embodiment, the four-bar link device 20 is a rail guide type transmission device formed so as to cooperate between the cam roller 23 and the press rail 4 (shown in FIG. 1 and described later). Based on the deformation, each jaw is driven. Any other form of drive, as long as it can drive a closed jaw in a manner that mimics the movement of a person compressing the filling pocket inwardly from the top of the dumpling or dumpling shaped food in the plane defined by the jaw It is clear that the mechanism may be used as a compression device for driving the mold set of the present invention, such as a flat linkage device mechanism (particularly a parallelogram linkage device), a crank link device, etc. Mechanisms, complex linkage mechanisms, fluid pressure (hydraulic or pneumatic) devices.

  When a fluid pressure device is used, the pressure fluid in the device is applied to drive the jaws. For example, a fluid chamber or cell is provided on at least a portion of each jaw. With the jaws 11 and 12 closed, when the chamber or cell is expanded with a high pressure fluid, the chamber or cell expands inward and contacts the dumpling dough, thereby causing the filling pocket to be Imitates the movement of a person compressing inward from the top of dumpling-shaped food. When the pressure is released, the chamber or cell deflates and contracts, thereby terminating the compression. Note that even if the fluid pressure device is used as described above, the jaw material as a whole may not necessarily be flexible as long as the jaw chamber or cell can fully expand and contract by itself. Should. Any means or device of the prior art may suitably be used to drive the jaws to effect the movement of the person compressing the filling pocket, without being limited to the preferred embodiments as described above. I understand that.

  As shown in FIGS. 5 and 6, the lower pan 30 includes, in addition to the two wing plates 34 each having a cam roller 34a, a rotating disk 31, a rotating bracket 32, and a spacer 33 (see FIG. 2). And a receiving tray 35. As shown in FIGS. 3 to 6, the two rotating disks 31 face each other, define a virtual hinge axis connecting the centers thereof, and the pair of wing plates 34 includes a pair of jaws 11, 12 opens and closes coaxially about the virtual hinge axis. More specifically, the rotating bracket 32 formed integrally with each wing plate 34 is only rotatable around an annular rail formed by the peripheral flange 31a of each rotating disk 31, and in this case, a pair of The wing plate 34 is guided to open and close coaxially with the pair of jaws 11 and 12 in the same manner as the butterfly flapping the wings. When each wing plate 34 hangs down, the spacer 33 comes into contact with the rotating bracket 32, and in this case, the lowest position of each wing plate 34 is determined by the spacer 33. When each wing plate 34 is stationary at the lowest position, the jaws 11 and 12 are opened flat. Each pan 35, which is firmly fixed on the lower pan 30, rises to the center of the mold set 10, where each pan cooperates with the jaws 11, 12 as part of the mold set and rests on them. Collective support is provided for the dough pad to be applied as well as the filling which is subsequently placed on the dough pad.

  As shown in FIG. 2, the lower pan 30 is further attached to a base frame 50, and the base frame 50 is configured to step the entire molding pallet 100 along the pallet rail 1 in a predetermined direction or continuously in the entire molding process. Support in a controllable manner through various positions corresponding to. In the embodiment shown in FIG. 1, the pallet rail 1 has a straight path and the molded pallet 100 is a pressure fluid device (eg, rodless pneumatic (or hydraulic) cylinder) or conventional along the straight path. Are precisely controlled and positioned by a drive mechanism (e.g., servo motor, timing belt or chain). However, in the prior art, pallet rails often take the form of rotary rails, and the molded pallet 100 is guided around the rotary rails by a gearbox driven by a central rotary motor.

  The molding process will be described below with reference to the mold set and the compression device shown in FIG.

  Both wing plates 34 of the lower pan 30 hang down due to gravity so that when the forming pallet 100 is located at the right end of the pallet rail 1, ie, the starting position, as shown in FIG. Both wing plates 34 are stationary at the lowest position defined by the spacer 33. In this position, the jaws 11, 12 are arranged flat, so that the mold set 10 is open in a disk shape. As described above, when the jaws 11 and 12 are opened flat, the jaws 11 and 12 are used together with the tray 35 to support the dough pad and the filling that is subsequently placed on the dough pad. To do. When the rotary rail 1 is used as in the prior art, the molding pallet 100 is first positioned at any position corresponding to the starting position for receiving the dough pad, and then the next place the filling on the center of the dough pad. Driven along the rail 1 to the position.

  Referring to FIG. 1, when the molding pallet 100 is driven in a predetermined direction (from right to left) along the pallet rail 1, each cam roller 34a is guided by a three-dimensional curve defined by the folding rail 2. As a result, the four-bar link device 20 and the jaws 11 and 12 positioned thereon are lifted from both sides of the support wing plate 34. Subsequently, the jaws 11 and 12 are completely closed like a bivalve, and then the folding rail 2 is switched to the pinch rail 3 connected thereto. The pinch rail 3 defines a path for both cam rollers 34a, and along this path, the closed jaws 11 and 12 force the top having sufficient hardness for filling, The filling is then sealed in the gyoza or gyoza-shaped food pocket so that the filling does not leak in any subsequent compression.

  Soon after the cam roller 34 a enters the pinch rail 3, the cam roller 23 already lifted upward comes into contact with each press rail 4. As shown in FIG. 1, the pressing rail 4 is a pair of rails that have the same contour and are arranged in parallel to each other. In a predetermined direction in which the forming pallet 100 is driven, each press rail 4 has a lower edge that curves downward, i.e., descends, at its first half, Each cam roller 23 is configured to be guided and biased so as to gradually deform the four-bar link device 20. The rail guide transmission device formed so as to be able to cooperate between the press rail 4 and the cam roller 23 is deformed via each four-bar link device 20, and finally the four-bar link device 20 is linear. Jaws 11, 12 in a closed state so as to mimic the movement of a person who is moved inward and compresses the dumplings or dumpling shaped food inwardly from the top of the dumplings or dumpling shaped food in a plane defined by the jaws The rocking member 22b for driving is rocked.

  When the cam roller 23 passes under the lowermost edge portion of each press rail 4, the contour of the next half portion of each press rail 4 defines a gradually rising path by the lower edge portion. However, shortly after the cam roller 23 enters the ascending path of each press rail 4, one cam roller 34 a of the wing plate 34 is guided to be switched from the corresponding pinch rail 3 to the release rail 5. During this time, the other wing plate 34 should still remain upright as its cam roller 34a contacts the pinch rail 3 on the other side. The separated wing plate 34 is pulled by gravity and slides downward along the release rail 5 so that it is placed flat at its lowest position. With the mold set 10 open only in the lateral direction, a push rod (not shown) is used to remove the final product of dumplings or dumpling shaped food from the mold set 10 onto a nearby conveyor belt, thereby Complete the entire process based on a dumpling molding machine that mimics the hand movements of molding handmade products.

  After one of the cam rollers 34a enters the release rail 5 and the other of the cam rollers 34a enters the corresponding rising path of the press rail 4, the flexible material jaws 11, 12 are based on their own elasticity ( And preferably with the aid of a spring 14), returning from the compression position corresponding to the innermost compression action to the home position corresponding to the pre-compression edge of the fabric pad. Thereafter, the molding pallet 100 may return from the left to the right in FIG. 1 in exactly the same way to the starting position shown in FIG. 1 and repeat the new cycle of the molding process. When a rotary rail is employed as in the prior art, the end position where the forming pallet 100 arrives last is actually the same position as the starting position because after all the forming steps, the pallet This is because when the pallet finally returns to the starting position, the pallet has just made a round path. At the starting position, the molding process of the new cycle is repeated.

  In the above-described embodiment, the jaws 11 and 12 integrally formed of a flexible material have been described. However, it is also possible to apply inflexible materials in order to successfully achieve a completely satisfactory effect. For example, only the outer surfaces of the jaws 11, 12 may be made of a flexible mold set material, and each jaw may include a rigid member linkage, such as a pivot joint and those It is a connecting rod between. In this case, the connectors 40a, 40b connecting the pivot joints or connecting rods are still used, thereby mounting the jaws 11, 12 on the four bar linkage 20 and the lower pan 3. Obviously, a four-bar linkage or other form of transmission mechanism to mimic human movement when compressing a filling pocket for dumplings or dumpling shaped food in the plane defined by the jaws 11, 12 Still functions in the same manner as described above for driving the jaws in the closed state.

  When using non-flexible material, the jaws 11 and 12 themselves do not have sufficient elasticity so that the jaws 11 and 12 do not spring back from the compressed position to the home position after compression of the dumpling filling pocket. There is. In this case, as described above, in order to drive the jaws 11 and 12 to return to the home position after each compression, the springs 14 are connected so as to connect the two opposing hinge pins 24 of each four-bar link device 20. There is a solution to provide.

  As another option, the pressing rail 4 of the present embodiment may be modified to further include a sub rail 4a and a sub rail 4b (not shown). In the direction of movement of the forming pallet 100, each subrail 4a has a lower edge that curves downward, that is, descends, and the lower edge compresses the dumpling filling pocket in a plane defined by the jaws 11,12. It is configured to press the pair of jaws 11, 12 in a closed state so as to imitate the movement of the person who performs the operation, and thus the sub rail 4a is referred to herein as a “press sub rail”. Each subrail 4b arranged on the downstream side of the press subrail 4a in the moving direction of the forming pallet 100 has an upper edge that is curved upward, that is, rising, and the upper edge has a pair of jaws. It is configured to drive in the reverse direction to return from the compression position to the home position, and thus the subrail 4b is referred to herein as a “return subrail”. As a variant, as long as the cam roller 23 is configured to move sequentially from the press subrail 4a to the return subrail 4b, each jaw 11, 12 can be any flexible material and / or spring member employed. It is driven and reciprocated between the compression position and the home position, regardless of the elasticity of.

  From the above description, even in the case of a mold set that does not have elasticity and its compression device, the two-way compression device including the transmission mechanism and the two-way press rails (subrails 4a and 4b) is 1 The pair of jaws is used to drive inward to mimic the movement of a person compressing the dumpling filling pocket, and also to drive the jaws outward from the compressed position back to the home position. be able to. Of course, as a further alternative, the bi-directional compression device may be a fluid pressure device incorporating a fluid chamber or cell, which has been described previously and will not be described further here.

  Obviously, even if the jaws 11 and 12 are flexible, a two-way compression device provided with a sub-press rail 4a and a sub-return 4b may be used, which overlap and will not be described further.
