Here, it is 360 degree/n ("/" represents the division sign) that the neutral angle θ that makes guide groove 53L counts n with respect to the unit structure of the flange part 51L that constitutes reel member 50L, and then, be configured by the phase place that is equivalent to this neutral angle θ that guide groove 53L is staggered, make that the weight balancing of whole reel member 50L is uniform with respect to the coiling axis.

For example, as Figure 12 (a) (b) shown in, be 4 o'clock at the unit structure number of flange part 51L, the neutral angle θ of guide groove 53L is 90 degree, the sum of flange part 51L is counted the integral multiple (being 8 here) of n for unit structure.

Direction of slip X+ side when from wireline reel is followed successively by flange part 51L ₁(1)～flange part 51L ₈(8) time, at the rotation coordinate system of right side view (make coiling direction R for just), flange part 51L ₁(1), 51L ₅(5) in the scope of 0 degree～90 degree, has guide groove 53L ₁, 53L ₅(the oblique line part that long and short dash line is represented) flange part 51L ₂(2), 51L ₆(6) in the scope of 90 degree～180 degree, has guide groove 53L ₂, 53L ₆(the oblique line part that solid line is represented), flange part 51L ₃(3), 51L ₇(7) in the scope of 180 degree～270 degree, has guide groove 53L ₃, 53L ₇(the oblique line part that solid line is represented), flange part 51L ₄(4), 51L ₈(8), the scope at 270 degree～360 degree has guide groove 53L ₄, 53L ₈(the oblique line part that long and short dash line is represented).

By the configuration of this guide groove, because the center of gravity of the 51L of flange part own is in a kind of like this state, that is, and flange part 53L ₁(1), 53L ₅(5) with flange part 51L ₃(3), 51L ₇(7) be symmetrical with respect to the coiling axis, flange part 51L ₂(2), 51L ₆(6) with flange part 51L ₄(4), 51L ₈(8) be symmetrical with respect to the coiling axis, so the whole center of gravity of reel member 51L is positioned on the coiling axis.

In addition, for the flange part 51L that sends side ₂(2), 51L ₄(4), 51L ₆(6) at the 54L of leading edge portion of the next side of coiling direction R ₂, 54L ₄, 54L ₆, respectively with respect to the flange part 51L that accepts side ₃(3), 51L ₅(5), 51L ₇(7) at the 54L of leading edge portion of the upper side of coiling direction R ₃, 54L ₅, 54L ₇The same plane of clamping, and opposed mutually.

And then, under the situation of this form of implementation, when the traction stretch wrap film,, sending the 54L of leading edge portion of side in order on film, not produce bending ₂, 54L ₄, 54L ₆, and accept the side leading edge 54L of portion ₃, 54L ₅, 54L ₇On, the mode on the inclined-plane that is parallel to each other with formation is carried out chamfering with certain angle respectively.

For example, as Figure 13 (a) (b) and shown in Figure 12 (a), at flange part 51L ₂(2) the 54L of leading edge portion ₂On, form with respect to the horizontal surface that comprises the coiling axis to oblique below bevelled guiding surface 58L ₂, at flange part 51L ₃(3) the 54L of leading edge portion ₂On, form with respect to the horizontal surface that comprises coiling axis bevelled guiding surface 58L obliquely upward ₃

For the other 54L of leading edge portion that sends side ₄, 54L ₆, and the 54L of leading edge portion that accepts side ₅, 54L ₇Too.

Here, with reference to Figure 14, the setting of the chamfer angle α of the 54L of leading edge portion is described.

From being wound up into coiling axial region 52L ₁On the outermost part of film via interval axial region 520L ₁Packaging film feeding is wound into next coiling axial region 52L ₂When last, owing to must as shown abovely not guide this film foldedly, so its track is preferably the spiral curve on specific cylinder curved surface.

Therefore, under the situation of this form of implementation, at first, in reel member 50L, when with flange part 51L ₁～51L ₄, the coiling axial region 52L between them ₁, 52L ₂With interval axial region 520L ₁Part when being object, for flange part 51L ₁Inside face and winding diameter be D film 2 on the intersection point P1 of uppermost bus L1 be starting point traction when twining, with the straight line L2 that part contacts that floats of film 2, and from flange part 51L ₄Inside face and coiling axial region 52L ₂On the intersection point P2 of nethermost bus work the straight line L3 that is parallel to straight line L2 that marks, described straight line L2, L3 shown in one of imagination comprises as outermost bus constitute the imaginary cylinder curved surface of a single-piece C with the simulation ground, side of interval axial region 520L.

Secondly, consideration is on this imaginary cylinder curved surface C, connect on intersection point P1 and the straight line L3 and leave, intersection point P2 is equivalent to the linear track S1 of film edge portion of helical curve that the some P3 of thin-film width distance constitutes, and connects and leave the linear track S2 of film edge portion of helical curve of some P4 formation that intersection point P1 is equivalent to the distance of thin-film width on intersection point P2 and the straight line L2.

Wherein, flange part 51L ₃The angle [alpha] 3 of chamfering, by guiding surface 58L ₃The angle decision that contacts with the track S2 of film edge portion.In addition, flange part 51L ₂The angle [alpha] 2 of chamfering, with flange part 51L ₃The angle [alpha] 3 of chamfering identical.

For

other flange part

51L ₁, 51L ₄～51L ₈The angle [alpha] 1 of chamfering, α 4～α 8 is similarly with flange part 51L ₃The angle [alpha] 3 of chamfering identical.

In addition, about flange part 51L ₂Guiding dip plane 58L ₂With interval axial region 520L ₁The relation of length d, do not contact with the track S1 of film edge portion sometimes, sometimes contact.

With the guiding dip plane 58L ₂The mode that contacts with the track S1 of film edge portion is not set axial region 520L at interval ₁Length d 1 time, be accompanied by by interval axial region 520L ₁Length d 1, with respect to flange part 51L ₂Be positioned at the 54L of leading edge portion of upper side ₂, and relatively be with it in 180 degree with respect to flange part 51L ₃Be positioned at the 54L of leading edge portion of the next side ₃The increasing of the film guide space of decision, imaginary cylinder curved surface C increases, and whereby, the advanced angle of spiral curve increases, so loose advantage is twined in the traction with film, in this form of implementation, has utilized this point.

On the other hand, do not adopt in this form of implementation, with guiding dip plane 58L ₂The mode that contacts with the track S1 of film edge portion is set axial region 520L at interval ₁Length d 2 (＜d1) time, above-mentioned film guide space diminishes, the traction of film is twined and become very tight although be accompanied by, and has the flange part of utilization 51L ₃Guiding dip plane 58L ₃And flange part 51L ₂Guiding dip plane 58L ₂Both guide film two ora terminalis, prevent the advantage of loose winding.

Figure 15 is the front elevation of expression with the film host body of winding film to the reel member of this form of implementation.

As shown in figure 15, this film host body 70C is used on the reel member 50L of this form of implementation implementing the method for winding of the film described later, is pulled the film 2 of the part of winding, one side respectively with guiding dip plane 58L ₃, 58L ₅, 58L ₇Contact, one side is positioned on the curve that is similar to spiral curve.

But, at the end face of the 54L of leading edge portion (not chamfering) and at interval in the side of axial region 520L, at least by making the part that contacts with film 2 approach imaginary cylinder curved surface C, can be in and more be similar on the track S1 of film edge portion, the S2d curve so that be pulled the film 2 of the part of winding.

Figure 16 is the diagram that expression is divided into the reel member of this form of implementation the example of a plurality of parts key elements.

Said reel member 50L is whole formation, but in this form of implementation, reel member 50L can be utilized a plurality of parts key elements to assemble formation.

For example, as shown in figure 16, utilize flange part 51L ₁And coiling axial region 52L ₁As the first parts key element 501L, in addition, with flange part 51L ₈As parts key element 502L, and then, with flange part 51L ₂And flange part 51L ₃, interval axial region 520L ₁And coiling axial region 51L ₂As parts key element 503L, can be with parts key element 501L and interconnective while of parts key element 503L, formation can be connected with each other parts key element 503L and parts key element 502L.

And this reel member 50L connects by 90 phase place that each parts key element 501L～503L is staggered mutually, the arbitrary integer that the number of flange part 51L is counted n as unit structure doubly can be set.

In addition, under the situation of this form of implementation, the viewpoint from the uniformization of weight balancing in flange part 51L1 (1), on the 51L8 (8), is provided with guide groove 53L ₁, 53L ₈, but from drawing the angle of stretch wrap film, be not need these guide grooves originally.

Therefore; in viewpoint from the protection of weight balancing uniformization and film; the flange part 51L that will have a guide groove 53L carries out above-mentioned being configured in the structure with the integral multiple of unit structure number, also can be configured in the flange part 51L that their both sides are not provided with guide groove 53L.

When implementing the method for winding of membrane according to the invention, for example, utilize multistage reel system described below.At first, with reference to this multistage reel system above the accompanying drawing.

Figure 17 is the example that expression is used to implement the multistage reel system of method of winding film of the present invention, is the front elevation of its simple structure of expression.Figure 18 is the left side view of the simple structure of this multistage reel system of expression.

As Figure 17 or shown in Figure 180, the multistage reel system 1 of this form of implementation has carrying device 10 and wind2 20.

The structure of carrying device 10 is, under the state of the reel member 11 of the rotatably mounted film 2 that is wound with regulation with feed shaft 12, gives the load of reel member 11 regulations.

In addition, the reel member 11 of carrying device 10, substantially the same with the structure of the reel member 50 of above-mentioned the first～five kind of form of implementation, external diameter about flange part 13 is bigger than the external diameter of the flange part 51 of above-mentioned form of implementation, sets according to the total length of insulativity adhesive film or anisotropic conductive adhesive film.

Wind2 20 is by winding mechanism 30, travel mechanism 40, and control part 60 constitutes.

Winding mechanism 30 has the wireline reel 31 with feed shaft 12 configured in parallel of carrying device 10.

This wireline reel 31, for example, with the through hole of the coiling axial region 51 of the reel member 50 of above-mentioned form of implementation with a little free-running fit, whereby, with reel member 50 under the mobile fixed situation of circumferencial direction, supporting to the state that axial direction moves.

On the end sections of a side of this wireline reel 31, drive division 32 is set.The frame mode of this drive division 32 is, the power of the coiling motor 32c that will be made of stepper motor passes to the gear 32a that is fixed on the wireline reel 31 via the train of gears 32b of regulation, makes wireline reel 31 rotations.

In addition, on the axle drive shaft of coiling motor 32c, be fixed with coder 32d, and then, near this coder 32d, the sensor 32e of light reflection-type is set.

This coiling motor 32c and sensor 32e are electrically connected to respectively on the control part 60.This control part 60 is counted the pulse count of coiling motor 32c according to the signal that comes from sensor 32e, and, according to the rotation of this pulse count control coiling motor 32c.

On the other hand, travel mechanism 40 has the axle drive shaft 41 that forms external screw thread as a pair of axle parallel with wireline reel 31, and slide shaft 42.On the end sections of a side of axle drive shaft 41, the drive division 43 of the structure identical with the situation of winding mechanism 20 is set.That is, this drive division 43 is by by will making the sledge motor 43b of axle drive shaft 41 rotations on the gear 43a of transmission of power to the axle drive shaft 41, and the transmittance type sensor 43d that can detect the coder 43c on this axle drive shaft 41 constitutes.These sledge motor 43b and sensor 43d are connected on the control part 60, carry out the control identical with winding mechanism 20.

On this axle drive shaft 41 and slide shaft 42, shifting board 44 and push plate 45 are installed.Shifting board 44 carries out screw thread with axle drive shaft 41 and combines, and, cooperate with respect to slide shaft 42 slidably.Push plate 45 do not combine with axle drive shaft 41 screw threads, can only with slide shaft 42 bearing fit states under, utilize not shown coil spring to load to shifting board 44 sides.

In addition, shifting board 44 and push plate 45 only form the shape of docking with the outer peripheral portion of the flange part 51 of reel member 50, for example ring-type together.

Secondly, for example, with the multiple occasion among the reel member 50A～50L that in above-mentioned multistage reel system, adopts the first～ten kind of form of implementation as an example, the preferred implementing form of membrane according to the invention method for winding is described.

Figure 19～Figure 24 is the diagram of method for winding of the film of this form of implementation of representing with left side view and front elevation with the state that utilizes reel member coiled film of the present invention.

Figure 25 (a) is the left side view of the film host body of expression form of implementation of the present invention, and Figure 25 (b) is the front elevation of this film host body of expression.

As shown in figure 17, at first, when being installed to the reel member 11 that is wound with film 2 on the carrying device 10, for example, after being installed to the reel member 50 of first kind of form of implementation on the wind2 20, so that the flange part 13 on the right side of the flange part 51A of shifting board 44 sides (rightmost side of Fig. 8) of wind2 20 and carrying device 10 (below be referred to as " right flange part 13a ") is configured in the mode on the same plane, with the reel member 50A of winding side reel member 11 location with respect to the feeding side.

Secondly, will be wound up into from the film 2 that the reel member 11 of sending side is pulled out on the coiling axial region 51A of reel member 50A of winding side.Here, for convenience of explanation, shown in Fig. 1 (a), make the flange part 51A of reel member 50A,, be followed successively by the first flange part 51A from the right side ₁, the second flange part 51A ₂, the 3rd flange part 51A ₃, the 4th flange part 51A ₄, in the coiling axial region 52A of reel member 50A, make first,

second flange part

51A ₁, 51A ₂Between the coiling axial region be that the first volume is around axial region 52A ₁, second,

third flange part

51A ₂, 51A ₃Between the coiling axial region be the second coiling axial region 52A ₂, the 3rd, the

4th flange part

51A ₃, 51A ₄Between the coiling axial region be the 3rd coiling axial region 52A ₃

And, according to order, make coiling motor 32c action from above-mentioned control part 60, make wireline reel 31 begin rotation, and, the counting of the pulse count of the motor 32c that begins to reel.

Whereby, reel member 50A remains under the state unmodified state of tension at the film 2 that will apply load with carrying device 10, to the first volume around axial region 52A ₁On reel ((b)) with reference to Figure 19 (a).

As Figure 20 (a) (b) shown in, the first volume of reel member 50A is around axial region 52A ₁Finish at part coiling adhesive film 2, begin to reel after the stripping film 2a, when control part 60 has just arrived the second flange part 51A according to the film 2 bonded assembly part 2b that the counting of the pulse count of coiling motor 32c is judged as the web-like of the stripping film 2a that sends side of stripping film 2a and winding side ₂Guide groove 53A in the time, the action of coiling motor 32c is stopped.

By the order of control part 60, make the pulse count of sledge motor action regulation, make axle drive shaft 41 rotations.Whereby, as Figure 21 (a) (b) shown in, reel member 50A, its second flange part 51A ₂Along the position of wireline reel 31, move to cooresponding distance above the right flange part 13a that sends side.In this case, owing to the stripping film 2a that sends side reverses with respect to the web-like film 2 of winding side, so this stripping film 2a is from the second flange part 51A ₂Guide groove 53A in overflow, near the 3rd flange part 51A ₃

As Figure 22 (a) (b) shown in, when keeping under this state unmodified situation, when making reel member 50A rotation once more, the second flange part 51A ₂Collude extension stripping film 2a with leading edge 54A.

Then, as Figure 23 (a) (b) shown in, reel member 50A is accompanied by rotation and will be in the second flange part 51A ₂The stripping film 2a that colludes the state of extension is wound up into the second coiling axial region 52A ₂On, soon, stripping film 2a sends end, the adhesive film 2 below transmitting, so, this film 2 is reeled.

On the other hand,, make sledge motor 43b action, reel member 50A is turned back to the second flange part 51A by order from control part 60 ₂With the right flange part 13a configuration state at grade of sending side.

Whereby, as Figure 24 (a) (b) shown in, reel member 50A, at parallel state with respect to the second coiling axial region 52A ₂Coiling is from sending the film 2 that side is come.

Below, with respect to the 3rd coiling axial region 52A of reel member 50A ₃, also carry out handling with top described the same coiling.

Like this, by implementing the method at reel member 50A coiled film of this form of implementation, obtain as Figure 25 (a) shown in (b), the exposed portions serve of the stripping film 2a of film 2 being drawn under the state that is wound on the coiling axial region 52A from flange part 51A, film 2 is wound into the film host body 70A of web-like on each coiling axial region 52A from sending side.

Figure 27～Figure 30 is with the diagram of utilization according to the method for winding film of this form of implementation of state representation of other reel member coiled film of the present invention.

In this method of winding film, adopt the reel member combination 60K that a plurality of reel member 50K with above-mentioned the 9th kind of form of implementation combine (below, abbreviate " reel member 50K " as).

Under the situation of this form of implementation, method for winding itself does not have difference with the method for winding of the reel member 50A that utilizes above-mentioned first kind of form of implementation, below, main explanation results from the different shape role of reel member 50K and reel member 50A.

In addition, Figure 27, Figure 29, Figure 30 correspond respectively to Figure 22 (a), Figure 23 (a), Figure 24 (a).

As shown in figure 27, in this form of implementation, with film 2 coiling axial region 52K reel finish after, be hooked under the state on the guide groove 53K at film 2, make after reel member 50K itself slides, make it to rotate.Whereby, stride across at film 2 under the state of

flange part

51K, 54K contacts with its leading edge.

As shown in figure 28, when reel member 50K was further rotated, the some 2c that film 2 contacts with leading edge 54K was to the first fastening groove 57K ₁Direction move, on the other hand, the part 2d that opens from the volume of film 2 is to the second fastening groove 57K ₂Direction moves.

Then, as shown in figure 29, meet the second fastening groove 57K at film 2 ₂The end, and drop into the first fastening groove 57K ₁State under, colluded on the marginal portion that is suspended to two flange part 51K.

Then, as shown in figure 30, film 2 is at first, second fastening groove 57K ₁, 57X ₂Between one side keep strenuous status, one side is winding on the next coiling axial region 52K.

And then, other form of implementation of the method for winding of film of the present invention is described.

For example; in the present invention; when utilizing any traction stretch wrap film among the reel member 50A～50L of the first～ten kind of form of implementation; the viewpoint that is not bent from protective film; coiling axial region 52 that coiled film finishes and next will the coiling axial region 52 of coiled film between; install the coiling axial region 52 that at least one does not carry out coiled film additional, that is, can skip a coiling axial region 52 coiled films 2.

According to this structure, pulling out the flange part 51 of usefulness from the coiling axial region 52 of the film 2 of having reeled and film 2 is being wound up into film 2 between the flange part 51 of coiling axial region 52 usefulness that will reel, with winding film is compared to the situation on all coiling axial regions 52, can draw winding with mild angle.

Wherein, this method preferably is applicable to the reel member 50F of above-mentioned the 6th kind of form of implementation.

In this case, with the guide groove 53F of flange part 51F in the curvature portion state of contact under traction stretch wrap film 2, after separating the fastening groove 57F that a coiling axial region 52F drops into the guide groove 53F that is positioned at adjacent another flange part 51F, be wound up on the next coiling axial region 52F.

Like this, by adopting above-mentioned what is called to skip one method of winding film, as shown in figure 26, obtain the film host body 70B that film 2 twines with mild traction angle to reel member combination 60F with a plurality of reel member 50F combination.

On the other hand, method of winding film as other form of implementation, similarly, never bend the viewpoint that film draws winding smoothly and set out, can utilize and send side and accepting respectively reeling of side and can append the reel member that traction twines the distance piece of usefulness between the axial region and reel.

In this case, from making the viewpoint of weight balancing uniformization, for example, preferably adopt the reel member 50L of the tenth kind of form of implementation shown in Figure 12 (a).

In addition, under the situation that adopts this reel member 50L, the moment of traction stretch wrap film, that is, in the moment that coiling axial region 52L is slided, 90 degree are necessary to stagger at every turn.

In addition,, in above-mentioned multistage reel system, adopt under the situation of reel member 50A of first kind of form of implementation shown in Figure 1 as the method for winding film of other form of implementation, with adhesive film 2 at the first volume around axial region 52A ₁In the last stage of reeling and finishing, just arrived the second flange part 51A at the winding part 2b of the stripping film 2a that sends side ₂Leading edge 54A place the time, the rotation of reel member 50A is stopped.

In this case, after the rotation that makes reel member 50A stopped, one side moved reel member 50A to axial direction, and one side is hooked on the second flange 51A with stripping film 2a ₂Leading edge 54A on.Later processing is the same with above-mentioned form of implementation.

In addition, in above-mentioned multistage reel system 1, adopt Fig. 3, Fig. 4 (a) (b) or Fig. 6 (a) shown in (b) second and third, under reel member 50B, the 50C or any situation among the 50E of five kinds of forms of implementation, compare with the situation of the reel member 50A that adopts first kind of form of implementation, the shape of each

guide groove

53B, 53C, 53E, vary in size.

Therefore, adopt these second and third, under the situation of reel member 50B, the 50C of five kinds of forms of implementation, 50E, be necessary to change the moment that the rotation that makes reel member 50 stops.But in others, for example, with adhesive film 2 in stage that the first volume is reeled and finished on axial region 52, after making the guide groove 53 of stripping film 2a by second flange part 51, moving on on the second coiling axial region 52, one side is colluded with its leading edge 54 and is hung on this point of simultaneously reeling, perhaps one side is colluded stripping film 2a and simultaneously moved on on the leading edge 54 that is suspended to second flange part 51 on this point of reeling afterwards on the second coiling axial region 52, and is the same with above-mentioned form of implementation.

And then, in above-mentioned multistage reel system 1, adopt under the situation of reel member 50D of the 4th kind of form of implementation of Fig. 5 (a) shown in (b), owing to be accompanied by the rotation of each flange part 51D, after its outer peripheral edge portion makes stripping film 2a slip, can be hooked on the leading edge 54D that cooperates protrusion 56D, so, compare with above-mentioned form of implementation, can enlarge the amplitude in the moment that the rotation that makes reel member 50D stops.

In addition, under the situation of this form of implementation, the periphery of the cooperation protrusion 56D of each flange part 51D make stripping film 2a by, be hooked on its leading edge 54D this point, identical with above-mentioned form of implementation.

In addition, as the method for winding of the film of other form of implementation, when mobile bar member 50 in axial direction, can make reel member 50 under the slow-footed state when reeling, continue rotation.

In this case, the rotative speed of reel member 50 is considered guide groove 53 this point that make stripping film pass through each flange part 51, and stripping film 2a is colluded this point decides on the leading edge 54 that is suspended to each flange part 51.

In addition, method of winding film as other form of implementation, adopting Fig. 9 (a) (b) or under any situation of reel member 50G, the 50H of shown in Figure 10 the 7th, the 8th kind of form of implementation, after coiling finishes on a coiling axial region 52, by the one side make this film on the leading edge 54 of flange part 51, the one side fall into fastening groove 57, can be fixed near the coiling axial region 52.

Here, the 7th kind of form of implementation, film is accompanied by the rotation of reel member 50G, by utilizing anti-shedding part 57G ₃Obstruction with kinematic constraint at stop hole 57G ₂In, change stop hole 57G at two ₂Interior posture is simultaneously strained and stop hole 57G ₂The mated condition of marginal portion is reeled on coiling axial region 52G.

In addition, under the situation of the 8th kind of form of implementation, film is accompanied by the rotation of reel member 50H, grips by the base section with fastening groove 57H, and as starting point, one side keeps strenuous status simultaneously to be wound up on the coiling axial region 52H with this fixing part.

In addition, in the present invention, fastening groove 57G, the 57H of this

reel member

50G, 50H, and fastening groove 57F, the 57K of aforesaid

roll shaft component

50F, 50K, except that with the film rolling coiled when multistage as automatically being fixed on the flange part 51,57 operations of automatically carrying out coiled film of these fastening grooves in the process with the operation of manually drawing stretch wrap film, can be used for film is fixed to flange part 51.

But, with the hand traction stretch wrap film time, be arranged on the guide groove 53 on the flange part 51, need not intrinsic function that film is passed through, for example the tip of film is pasted occasion on the coiling axial region 52 the operator, and, in occasion that film is inserted into fastening groove 57 etc., only needed the operation hole, do not established guide groove 53 and have only fastening groove 57 just enough.

Thereby in the present invention, fastening groove 57 is included in the notion of guide groove 53 in the scope that has common ground in a broad sense that makes film by flange part 51.For example,, guide groove 53 can be set, fastening groove 57 only be set,, can be used as the fastening groove 57 that " guide groove " is provided with the shape that comprises guide groove 53 for reel member 50K as " guide groove " for

reel member

50F, 50G, 50H.

As mentioned above, according to this form of implementation, after adhesive film being wound up on the coiling axial region 52 of reel member 50, stop (or slow down) in the rotation that makes reel member 50 afterwards, reel member 50 is moved to axial direction, so, can begin the coiling of film smoothly with the next one axial region 52 of reeling, so,, can be wound into multistage shape to suppress the diameter that adhesive agent overflows in the film for long film.

When the method for winding of the film of implementing this form of implementation, by adopting the first～ten kind of reel member 50 shown in the form of implementation, can be more effectively with the multistage shape of film rolling coiled that extends.

For example, according to the first～the 3rd, the 5th～ten kind of form of implementation, owing on each flange part 51, guide groove 53 is set, so, in the stage that finishes the coiling of film with a coiling axial region 52, pass guide groove 53 by film, film is moved on the next coiling axial region 52 smoothly.

Particularly, for first～the 3rd, the 5th kind of form of implementation, collude the extension film by edge (leading edge) with guide groove 53, in addition for the 6th～nine kind of form of implementation, by colluding the extension film with the fixing one side of fastening groove 57 one side, can be not loosely with winding film to next one coiling axial region 52.

And then, for guide groove 53 this point are set on each flange part 51, having can be not to overflow the advantage of ground mode coiled film from the outer peripheral portion of each flange part 51, and, as second and third, five, as described in nine kind of form of implementation, by guide groove is extended to coiling axial region 52 near, and, as the 7th, as described in eight kind of form of implementation, by fastening groove is extended to the coiling axial region near, have and can shorten the advantage that is wound into the length of film (stripping film) required on the next coiling axial region 52 from a coiling axial region 52 traction.

In addition, according to the 4th kind of form of implementation, cooperate protrusion 56 owing on each flange part 51, be provided with, so, not only has the advantage that film can be moved to next one coiling axial region 52 from the coiling axial region 52 smoothly, and, have and can collude the advantage of hanging film by enough cooperation protrusions 56, and can set the advantage of the timing amplitude of carrying out these actions in addition very widely.

And then, according to the second～nine kind of form of implementation, because each reel member 50 is in axial direction mutually combined, so, can be according to the degree of film lengthening, by making the suitably corresponding with it of reel member 50 in conjunction with the number increase and decrease.

And then, according to the first～nine kind of form of implementation, because with each guide groove 53 or respectively cooperate protrusion 56 being configured on the same position on the circumference of flange part 51, so, when making film in axial direction move, collude the extension film, can between each flange part 51, carry out with identical timing.

In addition, according to the 6th kind of form of implementation since with the thickness of flange part 51 thicken cooresponding degree, part that the films in the guide groove 53 are passed through makes the curved surface shape, so, when the traction stretch wrap film, can prevent the bending of this film.

Particularly,, skip one method of winding film, can more effectively prevent the bending of film by using what is called for this reel member 50.

And then, according to the 6th～nine kind of form of implementation, on the leading edge 54 of guide groove 53, fastening groove 57 is set, film is fixed on the flange part 51, so, when the traction stretch wrap film, can prevent the lax of film.
