Fig. 1 be the manufacture method of the stacked extruded resin sheet that present embodiment is shown outline figure.Fig. 2 illustrates the metallic roll of present embodiment and the outline cross sectional illustration figure of resilient roller.As shown in Figure 1, first, with different extruders 1,2, polycarbonate resin and acrylic resin limit are heated and melting mixing respectively, while extrude from the mouth mould 3 of co-extrusion modling, carry out stacked integration.
Then, cool being clamped in from the stacked extruded resin sheet 4 of the sheet-shaped molten of mouth mould 3 coextrusion along in 2 chill rolls 5 of general horizontal direction relative configuration, thus obtain the stacked extruded resin sheet 11 of touch panel.
Chill roll 5 as shown in Figure 2, by the metallic roll 6 of high rigidity with there is the resilient roller of metal film 9 and metallic elastic roller 7 is formed at peripheral part.Metallic roll 6 and metallic elastic roller 7 are formed as follows, and namely the rotary drive mechanism such as at least one and engine is connected, and two rollers rotate with the peripheral speed of regulation.
The metallic roll 6 of high rigidity be between metallic roll 6 and metallic elastic roller 7 by take up roll that the stacked extruded resin sheet 11 of sheet after clamping reels.Metallic roll 6 is not particularly limited, the common metallic roll used in extrusion molding since can adopting in the past.As concrete example, slotter (drilledroll), propellers etc. can be enumerated.The surface state of metallic roll 6 can be such as minute surface, also can have decorative pattern, concavo-convex etc.
Metallic elastic roller 7 has and is roughly cylindric and is set to the beaming roller 8 that rotates freely and columnar metal film 9, this metal film 9 configures in the mode of the outer peripheral face of this beaming roller 8 coating, and contact with the stacked extruded resin sheet 4 of melting, between these beaming roller 8 and metal films 9, enclose fluid 10, metallic elastic roller 7 can demonstrate elasticity thus.Above-mentioned beaming roller 8 is not particularly limited, such as, is formed by stainless steel etc.
Metal film 9 is such as formed by stainless steel etc., as its thickness, is preferably about 2 ~ 5mm.This metal film 9 preferably has bendability, flexibility etc., does not preferably have the jointless structure of weld part.There is metallic elastic roller 7 excellent in te pins of durability of such metal film 9, if and by metal film 9 mirror-polishing, can use in the same manner as common mirror roller, if give decorative pattern, concavo-convex to metal film 9, becoming can the roller of its shape of transfer printing, therefore easy-to-use.
This metal film 9 is fixed by the both ends of beaming roller 8, is sealed with fluid 10 between beaming roller 8 and metal film 9.As fluid 10, such as, can enumerate water, wet goods.By controlling the temperature of this fluid 10, temperature control can be carried out to metallic elastic roller 7.Said temperature controls to adopt the known control methods such as such as PID control, ON-OFF control.In addition, the gases such as air can also be used to replace fluid 10.
When clamping the stacked extruded resin sheet 4 of melting between such metallic roll 6 and metallic elastic roller 7, metallic elastic roller 7 is concavity via the stacked extruded resin sheet 4 of melting, along the outer peripheral face elastic deformation of metallic roll 6, and metallic elastic roller 7 and metallic roll 6 contact with the contact length L of regulation via the stacked extruded resin sheet 4 of melting.
As above-mentioned contact length L, be 1 ~ 20mm, preferably 1 ~ 10mm, more preferably 1 ~ 7mm as well.Make above-mentioned contact length L be setting, such as, can be carried out arbitrarily by the enclosed volume etc. of the thickness of adjustment metal film 9, fluid 10.It should be noted that, so-called above-mentioned contact length L, refer to the length of the straight line of the point that the point that connection metal resilient roller 7 and metallic roll 6 start via the stacked extruded resin sheet 4 of melting to contact contacts with end.
