Description

  The present invention relates to a film or sheet winding method and a core used for the method.

  Conventionally, in order to wind a long film or sheet of various materials (hereinafter, simply referred to as “film etc.”) for a predetermined length to form a roll body, A winding core is used.

  The winding core is also referred to as a core, and is usually required to stabilize the winding start and prevent skewing when winding a thin and soft material such as a film, or to prevent curling. For such a core, a paper, plastic or metal hollow tube is generally used.

  When winding a film or the like around such a core, first, apply an adhesive to the whole or part of the core to bond one end of the film or the like, or apply a double-sided adhesive tape to the whole or part of the core. Adhering and adhering one end of a film or the like on the double-sided adhesive tape, or setting one end of a film or the like on the cylindrical surface of the core, and adhering the film or the like to the core with an adhesive tape. In some cases, one end of a film or the like is set, and several films or the like are wound around the core in that state, and the one end is fixed by its own winding pressure of the film or the like. And it winds up, after fixing one ends, such as a film, to a core.

  By the way, when winding up a film or the like used for a predetermined treatment, since the end of the winding core is fixed as described above, only the winding core is extracted from the inside of the roll body. This is very difficult and is usually discarded together with films.

  Since the core composed of a hollow tube such as a paper tube is incurred in its material cost and manufacturing cost, there is a problem that the cost increases if it cannot be reused.

  Then, this invention is made | formed in view of such a situation, and after winding up a film etc., the core is extracted from a roll body, collect | recovered, and cost reduction can be achieved by reusing. It is an object to provide a winding method and a winding core used for the winding method.

  In order to solve the above problems, a film or sheet winding method according to the present invention is a method of winding a long film or sheet on a core, and winds both sides of the film or sheet leading end. A cylindrical support portion is formed by winding from a distal end side with a pair of both-side winding portions, and then the both-side winding portions are extracted from the formed cylindrical support portion.

  Further, it is a winding core for winding a long film or sheet, and includes a pair of both-side winding parts that wind up both sides of the film or sheet with a winding surface to form a cylindrical support part, In addition, the both-side winding part is configured to be separable from the cylindrical support part.

  According to these structures, it starts winding from the front-end | tip part of a film or a sheet | seat with a core provided with a pair of both-side winding part which winds up the both sides of a film or a sheet | seat, and forms a cylindrical support part. If it does so, the front-end | tip part of this film or sheet | seat will be first wound up by the both-side winding part, and a cylindrical support part will be formed with the film or sheet wound up by the both-side winding part several times. And after winding a film or sheet | seat around this cylindrical support part for a predetermined length and forming a roll body, a both-sides winding part is made into the left-right direction (film or sheet | seat) of a roll body (a cylindrical support part and a roll-shaped film or sheet). Pull out in the width direction of the sheet. At this time, since the winding surface of the both-side winding part is in contact only with the inner peripheral surface of both sides of the roll body (tubular support part), it is constituted by a hollow tube that is in contact with the entire inner peripheral surface of the roll body. Since the frictional force is extremely small compared to the winding core, it is easy to remove.

  In the winding method, the film or sheet may adopt a configuration in which a tip portion has rigidity.

  By setting it as the said structure, when a film or sheet | seat is wound up with a core from a front-end | tip part and a cylindrical support part is formed, this cylindrical support part will be formed more firmly. Therefore, when the film or sheet is further wound around the cylindrical support portion to form a roll body, the cylindrical support portion can be wound without being bent. As a result, it is possible to prevent the film or sheet to be wound from skewing and generating wrinkles on the roll body.

  In addition, it is preferable that a connection portion that connects the pair of both side winding portions is further provided.

  By setting it as the said structure, when winding a film or a sheet | seat, a both-sides winding part on either side can be synchronized and rotated only by driving one side. Thereby, since a difference does not arise in the rotational speed of a pair of both-side winding part, skewing of the film or sheet to wind up can be prevented, and it can wind up neatly without generating a curl etc.

  Moreover, it is preferable that the pair of both-side winding units further include a fixing unit for detachably fixing a leading end of a film or a sheet to the winding surface.

  By setting it as the said structure, a film or a sheet | seat can be firmly fixed now to a both-sides winding part, and it becomes easy to start winding. Moreover, since it can be detachably fixed, it can be easily extracted by releasing the fixing means even when the core is extracted after being wound into a roll.

  Moreover, it is preferable that the said fixing means is comprised by providing the slit of the direction orthogonal to a winding direction in the said winding surface.

  By setting it as the said structure, it can fix only by inserting the front-end | tip part of the film or sheet bent along the broken line in the slit provided in the winding surface of the both-side winding part, and can start winding easily It becomes like this. Also, when the winding core is removed from the roll body after winding, the film or sheet tip is simply inserted into the slit in the width direction of the roll body, so that the fixed state of the film or sheet tip is released. No work is required, and it can be extracted in the width direction as it is.

  Furthermore, the core of the film or sheet can be easily bent by bending it in the width direction, that is, bending it in a direction perpendicular to the length direction, and inserting it into a slit provided in a direction perpendicular to the winding direction. The film can be set straight (without skew) with respect to the winding direction. As a result, the film or sheet can be wound up neatly without causing curling due to skew.

  As described above, according to the present invention, after winding up a film or the like, the core can be easily extracted from the roll body and recovered, and the cost can be reduced by reusing the recovered core. Can be planned.

  Hereinafter, as an embodiment of the present invention, a laminating apparatus integrated with a printer apparatus, which can continuously perform image recording (printing) on a recording medium which is a premise of laminating processing. explain.

  FIG. 1 is a schematic configuration diagram of the entire apparatus, and FIG. 2 is a specific sectional side view thereof. The printer apparatus P is on the right side from the boundary line L, and the laminating apparatus R is on the left side.

  Since the printer apparatus P is not directly related to the present invention, the printer apparatus P includes a printing table 2 and a print head 3 that employs an ink jet recording system, and the recording medium A drawn out from the roll 1 Along the longitudinal direction, the sheet is intermittently conveyed on the printing table 2, during which printing is performed by the print head 3, and an image is recorded (formed) on the recording surface.

  A cutter device 5 is disposed downstream of the print head 3, and the recording medium A that has been recorded is cut into image units. Each recording medium A that is cut paper is transported on the transport path by a plurality of pairs of rollers, and is then discharged from the discharge port 8 and sequentially fed to the laminating apparatus R.

  Note that the configuration indicated by reference numeral 4 is a cleaner unit for cleaning the print head 3, the configuration indicated by reference numeral 6 is a dod impact printer unit capable of printing various information on the back surface of the recording medium A, and a configuration indicated by reference numeral 7. When the recording medium A is long so as to straddle both apparatuses P and R, the recording medium A is temporarily bent in a loop shape in order to absorb each processing speed difference between the printer apparatus P and the laminating apparatus R. Although a buffer may be formed, a relay tank for accommodating the loop, the configuration indicated by reference numeral 9 is an electrical component such as a control board, a power supply board, etc., and the configuration indicated by reference numeral 10 is not used for printing. This is a waste ink tank for collecting collected ink.

  The laminating apparatus R receives the recording medium A sent from the printer apparatus P from the receiving port 15. The laminating apparatus R is configured to be selectable between a case where the laminating process is performed and a case where the laminating process is not performed. When the laminating process is performed, the sorting unit 16 is in the first posture, and the recording medium A is the laminating unit. 17, and finally discharged onto the first tray 18 in a state of being subjected to a laminating process. On the other hand, when the laminating process is not performed, the sorting unit 16 is in the second posture, and the recording medium A is discharged onto the second tray 19 as it is.

  FIG. 3 shows an enlarged cross-sectional side view of the laminating apparatus R. Since the laminating apparatus R is directly related to the present invention, it will be described in detail below.

  The functional unit of the laminating apparatus R includes a laminating material supply unit 20 that supplies the laminating material B from the recording surface side (left side in the drawing) of the recording medium A that is conveyed on the conveying path after the distributing unit 16, and the recording target. Recording is performed between the under film supply unit 30 that supplies the under film E from the surface (base surface) side (the right side in the drawing) opposite to the recording surface of the medium A, and the supplied laminate material B and the under film E. A pressure bonding unit 40 that heat-presses the laminated body supplied with the medium A, a peeling unit 50 that peels the base material from the laminated material B after the thermocompression bonding, and a base material recovery unit that recovers the peeled base material 60, a separation unit 70 for separating the underfilm E after thermocompression bonding from the recording medium A, and an underfilm collection unit 80 for collecting the separated underfilm E.

  The laminate material supply unit 20 supplies the laminate material B from the roll as a continuous sheet, and includes a holder (laminate material roll holder) 21 that holds the roll of the laminate material B. On the other hand, the under film supply unit 30 supplies the under film E from the roll as a continuous sheet, and includes a holder (under film original fabric holder) 31 that holds the roll of the under film E.

  The pressure bonding unit 40 includes a drive roller 41 and a pressure roller 43. The driving roller 41 is disposed on the base surface side of the recording medium A, and the pressure roller 43 is disposed on the recording surface side of the recording medium A. Between the rollers 41 and 43, the laminate material B and the under film E and the recording medium A supplied therebetween are laminated (hereinafter, at least two of the recording medium A, the laminate material B, and the under film E are included). The stacked layers are collectively referred to as “laminated bodies”).

  Both rollers 41 and 43 have a heater at their shaft cores and are heating rollers. The heating temperature on the surfaces of the rollers 41 and 43 is set in the range of 60 to 120 ° C. for the driving roller 41, and is set in the range of 80 to 120 ° C. for the pressure roller 43. In addition, the roller (driving roller) 41 on the under film E side in the pressure bonding part 40 is also a heating roller, and the lower film is set below the heating temperature on the roller surface of the roller (pressure bonding roller) 43 on the laminate B side. It is for activating the heat-welding property between the laminate layer D and the under film E while suppressing the thermal influence on E.

  The peeling unit 50 is arranged in the vicinity of the peeling roller (peeling guide body) 51 disposed opposite to the conveyance path and the upstream side of the peeling roller 51 to increase the winding angle of the base material around the peeling roller 51. The step roller 52 is provided. The peeling roller 51 is disposed at a position sufficiently separated from the pressure-bonding portion 40 on the downstream side. This is because the laminate layer activated by the pressure-bonding portion 40 is activated (exhibits viscosity or the like). This is because an external force is applied to the laminate material B (laminate layer) after a normal equilibrium state (a state in which the adhesive force is increased). That is, when a predetermined time elapses from the heating in the crimping portion 40, the adhesive force of the laminate layer to the recording medium A is more reliably increased than the adhesion force between the base material and the laminate layer. If the peeling process is performed, the laminate layer is not peeled off from the recording medium A inadvertently, and only the base material is peeled cleanly. Therefore, a gap between the peeling portion 50 and the pressure-bonding portion 40 is provided.

  The base material collection unit 60 is a unit that winds and collects a continuous sheet-like base material peeled off from the laminate layer in a roll shape, and holds a roll of the base material (recovered base material roll holder or core). 61 is provided. The holder 61 is configured such that after collecting the base material, it can be extracted from the center of the roll formed by the collected base material and reused (recycled). FIG. 4A shows a schematic perspective view of the holder 61.

  The holder 61 includes a pair of both-side winding units 62 and 62 that wraps the base material to be collected and supports it from the inside, and a connecting unit 63 that is disposed between the pair of both-side winding units 62 and 62. Prepare.

  The both-side winding part 62 is formed in a columnar shape (short cylindrical shape) having a winding surface 64 for winding a side part of the base material to be collected as a peripheral side surface. The winding surface (circumferential side surface) 64 is formed with a slit 65 into which the tip of the recovered base material can be inserted. The slit 65 is formed from one end to the other end in a direction orthogonal to the circumferential direction of the winding surface 64 and toward the center (axial center) of the cylinder.

  The connecting portion 63 is formed in a rod shape (a column shape long in the axial direction). The rod-like connecting portion 63 has a smaller diameter than the both-side winding portions 62, and a pair of both-side winding portions 62, 62 are attached to both ends in the length direction so that the central axes thereof are on the same line. ing. At this time, at least one of the pair of both side winding portions 62 and 62 is detachably attached to the connecting portion 63.

  With such a configuration, after the base material is wound and collected in a roll shape, the one side winding portion 62 and the connecting portion 63 are separated, and the pair of both side winding portions 62 and 62 are separated from each other. It can be extracted in the direction. The holder 61 extracted in this way is reused for collecting the base material.

  On the other hand, the base material wound up and collected in a roll shape is discarded. At this time, since the pair of both side winding portions 62 and 62 are in contact (supported) with only the end portion (side portion in the width direction of the base material) of the inner peripheral surface of the roll body, Since the area in contact with the inner peripheral surface of the roll body is extremely small compared to the core (holder), it can be easily extracted. In the present embodiment, one side winding part 62 and the connecting part 63 are configured to be detachable, but may be configured to be separable at an intermediate part of the connecting part 63.

  The holder 61 having such a configuration is arranged such that the winding surfaces 64 and 64 are on the upstream side of the conveyance path with respect to the separation roller 51, so that the substrate to be separated from the conveyance path is transferred to the separation roller 51. Wrap together and determine the peel angle of the substrate relative to the transport path.

  The separation unit 70 includes a separation roller (separation guide body) 71 disposed to face the conveyance path. Similar to the peeling roller 51, the separation roller 71 is disposed at a position sufficiently separated from the pressure-bonding portion 40 on the downstream side, but this is activated (viscosity, etc.) by being heat-pressed by the pressure-bonding portion 40. This is because an external force is applied to the laminate material B (laminate layer) after the laminated layer D (shown) is in a normal equilibrium state (a state in which the adhesive force is increased). That is, when a predetermined time elapses after heating in the crimping portion 40, the adhesive force of the laminate layer to the recording medium A is surely increased. If the under film E separation step is performed in this state, the laminate layer is covered. Since the recording medium A is not inadvertently peeled off, an interval between the separation unit 70 and the crimping unit 40 is provided.

  The under film collection unit 80 collects a continuous sheet of the under film E onto which the excess laminate layer has been transferred by winding it into a roll, and holds a roll of the under film E (collected under film roll holder). 81. The holder 81 is arranged so that its winding surface is on the upstream side of the transport path from the separation roller 71, so that the under film E separated from the transport path is wound around the separation roller 71 and transported together. Determine the separation angle of the underfilm E relative to the path. The holder 81 may be configured in a hollow tubular shape that is a general winding core (holder) shape, or may be configured as the holder 61.

  The schematic configuration of each functional unit is as described above. The laminate material B is drawn in advance from the laminate material supply unit 20 and is inserted into the pressure bonding unit 40 (between the driving roller 41 and the pressure roller 43). FIG. 5 shows a schematic partial enlarged perspective view of the front end portion of the laminate material B. FIG.

  The laminate material B includes a rigid portion (leader) B1 formed of a material having rigidity at other end portions than the other portions. The rigid portion B1 is rigid but flexible enough to be wound around the holder 61. A bent line B2 is provided at the distal end of the rigid portion B1 in a direction orthogonal to the length direction of the laminate material B. The broken line B2 is formed by perforations in the present embodiment, but may be formed by a half cut, a press line, or the like. The rigid portion B1 is joined to the end of the laminate material B via a joint portion B3. In the present embodiment, the bonding portion B3 is adhered by an adhesive, but may be adhered by applying heat to the laminate material B, or may be adhered by a tape such as a double-sided adhesive tape. The rigid portion B1 may be of any type as long as it is a material having rigidity such as a thick laminate material B or a synthetic resin film, but in the present embodiment, the rigid portion B1 is made of paper. Yes. The rigid portion B1 may be formed integrally with the laminate material B.

  After the laminate material B is inserted into the crimping part 40, the tip part is wound around the holder 61 of the base material collecting part 60 as follows. 4B and 4C are schematic views illustrating a method of winding the base material (laminate B) around the holder 61. FIG.

  The tip of the base material is bent along a fold line B2 provided at the tip of the rigid portion B1. The bent portions are inserted into slits 65 and 65 provided on the winding surfaces 64 and 64 of the both-side winding portions 62 and 62 of the holder 61. At this time, the polygonal line B2 is provided in the direction orthogonal to the winding direction (the width direction of the base material), and the slits 65, 65 are also formed in the same direction. Therefore, the base material is set to the holder 61 straight without being skewed with respect to the winding direction only by inserting the bent portion into the slits 65 and 65.

  Then, when the holder 61 is rotated one or more times in this state, the broken line B2 portion at the tip of the substrate is turned from above (toward the roll circumferential surface) by the rigid portion B1 wound along the winding surfaces 64, 64. In the vertical direction). As a result, the bent portions inserted into the slits 65, 65 are fixed without being removed, and the base material is fixed to the holder 61. At the same time, the rigid portion B1 forms a hollow tubular support portion by being wound around the winding surfaces 64, 64. Even if the cylindrical support portion thus formed does not have a winding surface formed at the axial center portion of the holder 61 (between both side winding portions 62, 62), the base material bends and skews during winding. Prevents curling and curling. As a result, the base material can be neatly wound around the holder 61.

  The under film E is also drawn out from the under film supply unit 30 and inserted into the pressure bonding unit 40 (between the driving roller 41 and the pressure roller 43), and the leading end is wound around the holder 81 of the under film collection unit 80. Yes. In this state, the laminate material B and the under film E are overlapped on the conveyance path between the crimping portion 40 and the peeling portion 60. When the holder 81 has the same configuration as that of the holder 61, the under film E has a rigid portion in which a fold line in the width direction is provided at the tip as in the case of the tip of the substrate. Then, it is wound around the holder 81.

  Then, not only the driving roller 41 of the crimping unit 40 but also all of the holders 61 and 81 of the base material collecting unit 60 and the under film collecting unit 80 are driven by known driving force transmission means such as sprockets, chains, and gear trains. A driving force (not shown) is transmitted at the same time. By these synchronous driving, the laminate material B is pulled from the laminate material supply unit 20, the under film E is pulled from the under film supply unit 30, and the laminate is conveyed downstream along the conveyance path. ing.

  In the present embodiment, since the pair of both-side winding parts 62, 62 of the holder 61 are connected by the connecting part 63, the synchronous drive is applied to either one of the pair of both-side winding parts 62, 62. If it is transmitted, it is transmitted to the other by the connecting portion 63, and synchronization is obtained (there is no difference in rotational speed). However, the both-side winding units 62 and 62 may have independent structures that are not connected. In that case, if the rotation synchronization of the pair of both-side winding units 62, 62 is not taken, the substrate to be collected is skewed due to the difference in the rotation speed. Accordingly, a driving force transmission means that can synchronize between the pair of both-side winding parts 62, 62 is further provided, and the synchronous driving is transmitted to the driving transmission means or one of the both-side winding parts 62. It is necessary to.

  In this state, when the recording medium A is sequentially supplied from the receiving port 15, each recording medium A is interposed between the laminate material B and the under film E with the recording surface and the laminate layer facing each other. The laminate material B, the recording medium A, and the under film E are heated and pressure-bonded at the pressure-bonding portion 40.

  And the laminated body obtained by the crimping | compression-bonding part 40 is conveyed by the peeling part 50, and after a base material peels, it is further conveyed by the isolation | separation part 70 and the underfilm E is isolate | separated. At this time, the recording medium A and the under film E move relative to each other so that the base surface of the recording medium A and the under film E are separated from each other. That is, the recording medium A attempts to move further down the conveyance path, whereas the under film E moves in a direction different from the moving direction of the recording medium A (from the base surface of the recording medium A). Will be pulled in the direction of separation). Therefore, since the laminate layer of the non-laminate portion from which the substrate has been peeled also moves in the same direction as the under film E, the boundary between the portion with the recording medium A and the portion without the recording medium A (that is, the non-laminate portion and the laminate portion) The tensile force acts intensively at the boundary). As a result, only the non-laminate portion is surely cut off, and the edge of the laminate portion is clean along the edge of the recording medium A. As a matter of course, the laminate layer of the non-laminate portion separated from the laminate portion is recovered by the under film recovery unit 80 together with the under film E.

  As a result, the first tray 18 has a clean edge along the edge of the recording medium A, and a laminate layer that is in close contact with the recording surface without any air or the like between the recording medium A. Thus, the recording medium A laminated in the above is discharged.

  Further, the base material (laminate material B after the laminate layer is peeled off) and the under film E wound around the holder 61 of the base material recovery unit 60 and the holder 81 of the under film recovery unit 80 are discarded. At this time, the holder 61 is extracted and reused because the both-side winding portions 62 and 62 can be separated (separated) from each other. When the holder 81 has the same configuration as the holder 61, it can be reused in the same manner.

  By the way, in this embodiment, in order to improve maintainability, the apparatus of the laminating apparatus R so that the laminating material supply part 20, the under film supply part 30, the base material collection part 60, and the under film collection part 80 can be handled integrally. The magazine is designed to be detachable from the main unit. 6 is a cross-sectional side view of the magazine 100, and FIG. 7 is an external perspective view of the magazine 100 viewed from the opposite side.

  A casing 101 of the magazine 100 is arranged at appropriate positions between the side frames 101a and 101b and the side frames 101a and 101b arranged on the left and right in the width direction of the laminate material B and the under film E, and the side frame 101a. , 101b are connected to each other at a predetermined interval. Further, the side frames 101a and 101b are respectively divided into front and rear parts, and the side frames 101a-1 and 101b-1 at the front part (left side in FIG. 6 and right side in FIG. 7) and a connecting frame for connecting them. 101c-1 and 101c-2 constitute the front housing 1A, while the rear frames (the right side in FIG. 6 and the left side in FIG. 7) side frames 101a-2 and 101b-2 and the connecting frame 101c connecting them. −3, 101c-4, and 101c-5 constitute the rear housing 1B.

  Therefore, the housing 101 can be separated forward and backward. More specifically, a part 101d of the rear housing 101B is rotatably supported by the front housing 101A and swings so as to be openable and closable with respect to the front housing 101A. In addition, a lock mechanism 102 is provided in the housing 101 in order to maintain a closed position where the front housing 101A and the rear housing 101B are combined.

  The conveyance path of the recording medium A that connects the crimping unit 40 and the peeling unit 50 is set along the boundary portion between the front housing 101A and the rear housing 101B. Accordingly, at the open position where the angle between the front housing 101A and the rear housing 101B is opened, the transport path is opened, and the recording medium A on the transport path can be taken out.

  The laminate material supply unit 20, the peeling unit 50, and the base material collection unit 60 are arranged in one housing (the front housing 101 </ b> A located on the recording surface side of the recording medium A), while the under film supply unit 30. The separation unit 70 and the under film collection unit 80 are disposed in the other housing (the rear housing 101B located on the base surface side of the recording medium A).

  Further, the connecting frame 101c-1 is arranged so as to surround the laminate material supply unit 20 in cooperation with the connecting frame 101c-3, and the connecting frame 101c-2 is arranged so as to surround the base material collecting unit 60. The connecting frame 101c-4 is arranged so as to surround the under film supply unit 30 in cooperation with the connecting frame 101c-3, and the connecting frame 101c-5 is arranged so as to surround the under film collecting unit 80. Therefore, each connecting frame 101c also functions as a dustproof cover.

  On the other hand, the crimping portion 40 is disposed on the apparatus main body side of the laminating apparatus R independently of the magazine 100. That is, returning to FIG. 3, the drive roller 41 and the pressure roller 43 of the pressure bonding unit 40 are rotatably supported by the housing 90 of the apparatus main body, and the edge of the magazine 100 is cut. The concave portions formed in each of the front housing 101A and the rear housing 101B of the magazine 100 are provided so that the driving roller 41 and the pressure roller 43 of the pressure bonding portion 40 do not interfere with the magazine 101.

  In addition, this invention is not limited only to the said embodiment, A various change in the range which does not deviate from the summary of this invention is possible.

  In the present embodiment, the pair of both side winding portions 62, 62 are connected by a single bar-shaped connecting portion 63, but may be connected by a plurality of bar-shaped connecting portions, and may have a large diameter. May be connected by a connecting portion that is not constant, and any member that can transmit the driving force transmitted to one of the two side winding portions 62 to the other side winding portion 62 may be used. In this case, these connecting portions wind the base rigid portion B1 around the pair of both-side winding portions 62, 62 so that the pair of both-side winding portions 62, 62 are not easily pulled out from the recovered roll body. It must be formed and arranged so as not to contact the inner peripheral surface of the cylindrical support portion formed in this way. Since the roll body (tubular support portion) does not come into contact with the inner peripheral surface by being formed and arranged in this way, the frictional resistance when the pair of both side winding portions 62 and 62 are extracted from the roll body does not increase.

  In this embodiment, in order to fix the tip of the substrate, the slits 65 are provided in the both-side winding unit 62. However, after the substrate is wound, a fixing means that can be switched between a fixing posture and a releasing posture is wound. The chamfer 64 may be provided.

  Moreover, in this embodiment, although it is the winding method and core for forming the roll body of the base material which the disposal after a process is scheduled, for example, the roll body for shipping as a product is formed. It may be a winding method or a core used at the time.
