2) the bonding layer of resin
When by on the thin slice of extruding as curtain melts described resin when bonding airbond evaporation layer 27 and ply of paper 21, polyolefin group thermoplastic resin layer 25 is as bonding coat.Consider the contraction processibility at low temperatures that reduces thin slice, MFR preferably is at least 3 (g/10min).If MFR is less than 3 (g/10min), the low temperature processibility is very poor, and increases along with thin slice shrinks, and can break in thin evaporated film, influences the airbond characteristic.MFR is preferably in the scope of 5-14 (g/10min).
For polyolefin group thermoplastic resin layer 25, can use polyethylene, polypropylene, hexenoic acid ethylenic copolymer or ionomer.From the extruding angle, polyethylene is the most preferred.
When described polyolefin group thermoplastic resin fusing and extruding are curtain or film like, temperature preferably is low to moderate the airbond characteristic of not destroying airbond evaporation layer 27.Optimum condition is different with pushing thickness according to the type of used resin.Being preferably 320 ℃ or lower for the polyethylene temperature, more specifically is 300 ℃ or lower.If temperature surpasses 320 ℃, thin evaporated film will be subjected to the damage of heat, and the airbond characteristic is damaged.If temperature is 250 ℃ or lower, extrusion defect will take place.Preferred fusing/extrusion temperature is 250-320 ℃.
When extrusion temperature becomes 260 ℃ or when lower, the autoxidation when freely being dripped by the T punch die becomes insufficient, and the adhesion between aquaseal base sheet and the paper becomes insecure.Therefore, preferably adopt forced oxidation to remedy this inadequate oxidation.For extruded layer pressing plate in this case, preferably use surface treatments such as ozone processing or bunch discharge processing simultaneously.
For ozone processing, spray the ozone of right quantity at least one side of molten resin, reduction resin temperature both within reason does not vibrate yet.Producing ozone with known method does not have problems.For example, be easy to produce ozone, by carrier gas delivery of ozone in a large number by the air in airtight container discharging.
The thickness of polyolefin group thermoplastic resin layer 25 is determined by resinous principle, extrusion temperature and other conditions.For example, during the extrusion molding polyethylene, thickness is preferably 10-20 μ m under being lower than 300 ℃ temperature.If thickness surpasses 20 μ m, stress increases when resin cooling and hardening, and distortion is passed to thin evaporated film, can cause and break.If thickness is lower than 10 μ m, when extruding, can have problems.Preferred resin thickness is 15-20 μ m.

At first with reference to Figure 12 A and Figure 12 B former 114 and the sheet material fixer 116 that uses with former are described, they all are the elements of cover piece moulding press.Figure 12 A is the schematic plan view of former 114 and sheet material fixer 116.Figure 12 B is the schematic sectional view along the line 12B-12B acquisition of former 114 shown in Figure 12 A and sheet material fixer 116.
Former 114 has plane 114a, is used for placing the sheet material (not shown) that is used for cover piece 14.Be provided with opening 114c on sheet material placement plane 114a, predetermined form of flat part 14a of all 114b and cover piece 14 is corresponding in it.Especially, the profile of interior all 114b is identical with the side of the flat part 14a of the cover piece 14 shown in Figure 11 A and Figure 11 B with the size cardinal principle, wherein peripheral sweep 14b crooked (promptly inner surface).The opening 114c of sheet material placement plane 114a cuts sth. askew out and enters edge 114d.Enter cutting sth. askew of edge 114d and be shaped as convex curve.
By the screw (not shown) being inserted among the fix screw patchhole 114e, former 114 is fixed on the desired location (not shown) of workshop (not shown), and the cover piece moulding press has been installed in the workshop.
With reference to the structure of Figure 13 A to 13D explanation formpiston 118, formpiston 118 is another elements of described cover piece moulding press, and is used in combination with former 114 and sheet material fixer 116 below.Figure 13 A is the schematic plan view of another element formpiston 118 of cover piece moulding press.Figure 13 B is the schematic side elevation of formpiston 118 among Figure 13 A.The dotted line C that Figure 13 C is replaced by unexpected misfortune in the formpiston 118 of Figure 13 A around the schematic amplification view of part.Figure 13 D is the schematic enlarged side view that the amplifier section of Figure 13 C obtains from arrow D direction.
Step portion at least (turning) 118d of periphery 118a is along the mating surfaces 118b angle [alpha] that slopes inwardly, because it further leaves the bending length of peripheral sweep 14b from mating surfaces 118b from position P, the distance that described position P leaves mating surfaces 118b is shorter than BL.The part from mating surfaces 118b to position P, step portion at least (turning) 118d of periphery 118a is formed by the straight line with mating surfaces 118b cardinal principle quadrature.
In formpiston 118 surfaces, be formed centrally connecting bore 118e.What link to each other with connecting bore 118e is the end portion (shown in the Reference numeral 122 among Figure 14 A and Figure 14 B) of the reciprocating member of known reciprocating apparatus, described reciprocating apparatus supports formpiston 118, and formpiston 118 is corresponding with the opening 115c of the sheet material placement surface 114a of the former 114 of the desired location (not shown) that is fixed on described workshop (not shown).Described device makes formpiston insert crank motion between the position of opening 114c predetermined lengths at isolated location and formpiston 118, is positioned at described isolated location formpiston 118 on the opening 114c of sheet material placement surface 114a of former 114.
With reference to Figure 14 A and Figure 14 B explanation process of cover piece moulding press by the cover piece 14 shown in the molded Figure 11 A of sheet material and Figure 11 B, described cover piece moulding press is made of former 114, sheet material fixer 116 and formpiston 118 below.
Figure 14 A has illustrated the schematic longitudinal sectional view of using the cover piece moulding press to be made cover piece process before by sheet material.Figure 14 B has illustrated the schematic longitudinal sectional view of using the cover piece moulding press to be made cover piece process afterwards by sheet material.
In described cover piece moulding press, formpiston 118 is upwards isolated with the opening 114c of the sheet material placement surface 114a of former 114, former 114 is fixed on the unshowned desired location of workshop (not shown) as mentioned above, and sheet material 120 is placed on the sheet material placement surface 114a, and sheet material fixer 116 is isolated with the sheet material placement surface 114a of former 114 simultaneously.
At this moment, the opening 114c of sheet material 120 relative sheet material placement surface 114a places with one heart, corresponding with the reservation shape of opening 114c (promptly corresponding, corresponding) with four turnings of the step portion of the predetermined profile of opening 114c with four turnings of the step portion of the predetermined profiles of sheet material 120.
Subsequently, the sheet material 120 that is placed on as mentioned above on the sheet material placement surface 114a of former 114 is squeezed to sheet material fixer 116, shown in Figure 14 A.At this moment, sheet material fixer 116 is in line with the opening 114c of sheet material placement surface 114a, corresponding with the reservation shape of opening 114c (promptly corresponding, corresponding) with four turnings of the step portion of the predetermined profile of opening 114c with four turnings of the step portion of the predetermined profile of sheet material fixer 116 edge of opening 116a.This state is shown among Figure 14 A.
In Figure 14 A, Reference numeral 122 has shown, the end portion of the reciprocating member of known reciprocating apparatus (not shown), described device make formpiston 118 up-and-down movement between the position of the opening 114c predetermined length of the sheet material placement surface 114a of isolated location shown in Figure 14 A and formpiston 118 insertion formers 114.
Subsequently, formpiston 118 uses opening contact and extruding mating surfaces 118b the sheetlet 120 to the sheet material placement surface 114a that be placed on former 114 of described reciprocating apparatus by sheet material fixer 116.At this moment, the opening 114c of formpiston 118 relative sheet material placement surface 114a places with one heart, corresponding with the reservation shape of opening 114c (promptly corresponding, corresponding) with four turnings of the step portion of the predetermined profile of opening 114c with four turnings of the step portion of the predetermined profile of the mating surfaces 118b of formpiston 118.
When formpiston 118 further is squeezed by reciprocating apparatus, formpiston 118 will with the contacted sheet material 120 of mating surfaces 118b by entering the opening 114c that edge 114d pushes flat part 14a.
Subsequently, make the flat part 14a of predetermined profile with cover piece 14 with the part of the contacted rectangular sheet 120 of mating surfaces 118a of formpiston 118.The part of the sheet material 120 that stretches out from the mating surfaces 118a of formpiston 118 is drawn among the opening 114c that enters the former 114 of (being in the flat part 14a periphery) the edge 114d of opening 114c of sheet material placement surface 114a of former 114.This draws between part is fixed on the interior all 114b of opening 114c and formpiston 118 in opening 114c the periphery 118a, and the periphery along interior all 114b of opening 114c from flat part 14a is to keeping this state with the predetermined direction of flat part 14a surface crosswise (promptly to opening 114c enter edge 114d), and is bent into crooked periphery sweep 14b.
This state is shown among Figure 14 B, and wherein cover piece 14 is molded shown in Figure 11 A and Figure 11 B.
As mentioned above, when the sheet material 120 of the sheet material placement surface 114a that is placed on former 114 is pushed the opening 114c of sheet material placement surface 114a of former 114 by formpiston 118, the part of the sheet material 120 in the opening 114c of the sheet material placement surface 114a that pushes former 114 by formpiston 118 and be squeezed to by sheet material fixer 116 between the part on the sheet material placement surface 114a of former 114 and produce tension force.
Because the edge 114d that enters of the opening 114c of sheet material placement surface 114a is cut sth. askew, boundary edge 118c between the mating surfaces 118a of periphery 118b and formpiston 118 is also cut sth. askew, and described pulling force is dispersed in sheet material 120 on all parts that squeeze out from the mating surfaces 118a of formpiston 118 almost evenly.Even therefore the profile of the flat part 14a of cover piece 14 has for example square step portion, along flat part 14a one side surface (marginal portion 14b is at this bending, i.e. outer surface) and in the face of the border between the surface of the curved edge part 14b of flat part 14a can be not wrinkling.In addition, even cover piece 14 is ply woodes, above-mentioned fold can not take place yet, can not be mixed in breaking in the described fold in the superficial layer yet, the space can not occur in the laminate layers.
At least the step portion of the periphery 118a of formpiston 118 (in this example for turning) 118d is the straight line with mating surfaces 118b quadrature, except cutting sth. askew to the boundary edge 118c of position P, the distance that position P leaves mating surfaces 118b is littler than BL, BL is the bending length of the periphery sweep 14b of cover piece 14, and when it leaves mating surfaces 118b and further leaves described position P along the mating surfaces 118b α angle that slopes inwardly.This prevents that pulling force from concentrating on the corresponding position of step portion with the sheet material 120 that squeezes out from the mating surfaces 118a of formpiston 118.With the corresponding position of described step portion 118d can be not wrinkling.In addition, even cover piece 14 is ply woodes, above-mentioned fold can not take place yet, can not be mixed in breaking in the described fold in the superficial layer yet, the space can not occur in the laminate layers.
As mentioned above, after being molded into from sheet material 120, when formpiston 118 arrives desired depth in the opening 114c of the sheet material placement plane 114a of former 114, the end of curved edge 14b leaves from the opening 114c of former 114, be inserted in the column main part end of box by opening with back cover member 14, and be supplied to treating process closure of openings.
In above-mentioned example, at least the step portion of the periphery 118a of formpiston 118 (in this example for turning) 118d is the straight line with mating surfaces 118b quadrature, except cutting sth. askew to the boundary edge 118c of position P, the distance that position P leaves mating surfaces 118b is littler than BL, BL is the bending length of the periphery sweep 14b of cover piece 14, and when it leaves mating surfaces 118b and further leaves described position P along the mating surfaces 118b α angle that slopes inwardly.
Though be straight line on whole periphery 118a with mating surfaces 118b quadrature, except cutting sth. askew to the boundary edge 118c of position P, the distance that position P leaves mating surfaces 118b is littler than BL, BL is the bending length of the periphery sweep 14b of cover piece 14, and when it leaves mating surfaces 118b and further leaves described position P along the mating surfaces 118b α angle that slopes inwardly, but can obtain the effect identical with above-mentioned embodiment formpiston 118.
And, in above-mentioned example, the predetermined profile of the flat part 14a of cover piece 14 and with the profile of the periphery 118a of the corresponding formpiston 118 of described profile be square substantially with ladder turning 14c, according to groundwork of the present invention, described profile can be outer circle, ellipse, polygon or a uncertain shape of square, but they should comprise that step portion is to become convex surface or concave surface.
Described cover piece moulding press is the machine by the molded cover piece of sheet material, described cover piece comprises the flat part and the outward extending edge of reservation shape, described edge from the flat part periphery to the predetermined direction bending of flat part surface crosswise, close the opening of column box main portion end when time in the opening that is inserted into described end, and in peripheral sweep supporting in interior week by end portion.But, even the reservation shape of the flat part of described cover piece has square step portion, along flat part one side surface (marginal portion is in this bending) and in the face of the border between the surface of the marginal portion 14b of flat part 14a or can be not wrinkling on the corresponding position of the step portion of described curved edge and flat part.In addition, even cover piece 14 is ply woodes, above-mentioned fold can not take place yet, can not be mixed in breaking in the described fold in the superficial layer yet, the space can not occur in the laminate layers.
With reference to Figure 15 A to Figure 15 H above-mentioned cover piece is fixed on method on the main component below.
