On the other hand, as shown in FIGS. 1 and 4, the sizing jig 22 has a substantially rectangular fixed block 25 in which a guide groove 26 opening upward is formed along the longitudinal direction, and a bottom wall of the guide groove 26 is formed. A fixed portion guide hole having a cross-sectional shape substantially equal to a cross-sectional shape of a portion (hereinafter, this portion is referred to as a "fixed shape portion 50") below the glass lip 5 of the molded body w (wind molding) below. 27 (fixed guide wall in the present invention) is also formed along the longitudinal direction. The fixed portion guide hole 27 has a portion corresponding to the upper end of the glass lip 5 and the leg portion 3 of the molded body w opened in the center of the bottom wall of the guide groove 26 along the longitudinal direction. The portion above the support portion 7, that is, the portion where the support portion 7, the head portion 8, and the panel lip 10 are combined is referred to as a "variable shape portion 51".
[0027]
A recess 28 is provided on one side wall of the guide groove 26, and a head guide piece 29 made of a disk-shaped member is rotatably attached to the recess 28. The head guide piece 29 is a portion for supporting the lower surface of the head portion 8 of the molded body w, and a cam surface 30 whose height continuously changes as shown in FIGS. Have been. The head guide piece 29 is attached to the fixed block 25 so that the outer peripheral edge of the head guide piece 29 projects into the guide groove 26 by a predetermined width.

A vacuum passage 35 connected to the vacuum device Vac is formed at a position where the lower surface of the panel lip 10 and the lower surface of the auxiliary lip 6 of the lip guide piece 32 and the fixing portion guide hole 27 contact each other. The panel lip 10 and the auxiliary lip 6 are respectively brought into close contact with the periphery of the opening by the negative pressure of the passage 35.
[0033]
Since this device has the above-described configuration, the window molding is started, and when the variable extruder 20 continuously extrudes the resin material while changing the cross-sectional shape, the molded body w becomes a sizing treatment. It is cooled in the cooling water tank 21 while passing through the fixed portion guide hole 27 and the guide groove 26 of the tool 22, where it is fixed in shape and then sent on the roller 37 to be taken up by a winding device (not shown).
[0034]
Here, the molded body w extruded from the variable extruder 20 has the fixed shape portion 50 inserted into the fixed portion guide hole 27 and the variable shape portion 51 inserted into the guide groove 26 in the sizing jig 22. . Then, for example, when the side molding section M _s moldings w while gradually reducing the height of the strut portion 7 during molding of the extruded from the variable extruder 20, in accordance with the change in the extrusion shape of the variable extruder 20 ( The rotation of the head guide piece 29 is continuously controlled so as to change the position where the head guide piece 29 faces the guide groove 26 from the top area a to the notch area c side (by delaying the phase by the time lag), and the lip guide piece 32 Is controlled to descend. Thus, the head portion 8 and the lower surface of the panel lip 10 are continuously contacted and supported by the head guide piece 29 and the lip guide piece 32.
[0035]
Also, when moving to shaping of the upper molding part W _u from modeling the above mentioned side molding section W _s, the rotary head guide piece 29 where the notches 36 of the head guide piece 29 is positioned within the guide groove 26 is At the same time as stopping, the lip guide piece 32 is stopped at the lowest position. At this time, the formed body w sent from the variable extruder 20 loses the drip groove 9 and the head portion 8 is polymerized and welded on the upper surface of the glass lip 5, but the head guide piece 29 is guided by the notch 36. Since it is located in the groove 26 and retracted from the position at which the head 8 of the molded body w is sent out, interference with the head 8 is avoided. Therefore, the head portion 8 is supported by the wall surface of the fixed portion guide hole 27 via the glass lip 5 while being polymerized and welded to the upper surface of the glass lip 5.
[0036]
Therefore, this when the production apparatus used is always reliably abut the bottom support surface of the head portion 8 and the panel lip 10 also during shaping of any portion of the side molding section M _s and the upper molding section M _u is the sizing jig 22 Then, the molded body w is fixed in shape with substantially the same cross-sectional shape as when the material is extruded from the variable extruder 20.
[0037]
Also, the actuators 31 and 34 for operating the head guide piece 29 and the lip guide piece 32 can detect a change in the shape of the molded body w using a sensor and can be controlled based on the signal. In the apparatus of this embodiment, the operation is performed by delaying the phase by the time lag of sending out the compact w with respect to the operation of the elevating actuator (not shown) of the variable extruder 20. As a result, the number of parts is reduced and the control is simplified. As a result, the manufacturing cost of the device is reduced.
[0038]
Further, in the manufacturing apparatus of this embodiment, the head guide piece 29 for supporting the lower surface of the head portion 8 of the molded body w is formed by a disk-shaped member having a notch 36 in a part of the outer peripheral surface, and the upper surface thereof is formed. A cam surface 30 whose height changes continuously is formed on the side outer peripheral edge, and the head guide piece 29 is rotated by a rotation actuator 31 to raise and lower the support surface with respect to the head part 8 and to move the head part 8 between the head part 8 and the head part 8. Since the evacuation for avoiding the interference can be performed in a series of rotation operations, the number of actuators can be reduced and the structure of the entire apparatus can be simplified. Therefore, also at this point, the production at low cost is possible.
[0039]
However, the embodiments of the present invention are not limited to those described above. For example, the head guide pieces may be operated by two actuators as in the second embodiment shown in FIGS. good.
[0040]

While being formed, the head guide piece 129 and the lip guide piece 32 are arranged in the guide groove 126, but the head guide piece 129 is formed of a substantially rectangular plate-shaped member instead of a disk-shaped member. The head guide piece 129 is supported by an advancing / retracting actuator 41 attached to the lower end of the lifting / lowering actuator 40, and is operated to move in the vertical and horizontal directions by the operation of the two actuators 40, 41. The lip guide piece 32 is moved up and down by an elevating actuator 34 as in the first embodiment.
[0041]
To describe the operation of the manufacturing apparatus, for example, when shaping the side molding section M _s of the window molding are both lifting actuator 40 of the head guide member 129 and the lip guide piece 32 in a state in which advancing the reciprocating actuator 41, 34 is moved up and down in accordance with the change in the cross section of the variable extruder (delayed by a time lag as in the first embodiment), and as shown in FIG. And the lower surface of the panel lip 10 is continuously contacted and supported. Further, when shaping the upper molding section M _u of the window molding has a retractable actuator 41 is retracted moving together to the lowermost both elevating 40,34. As a result, as shown in FIG. 9, the head guide piece 129 is displaced from the feed path of the head part 8 of the molded body w to avoid interference with the head part 8, and the lip guide piece 32 is moved to the panel lip 10 at the lowest position. Abut the lower surface of the abutment.
[0042]
Also in the case of the device of this embodiment, the head 8 and the lower surface of the panel lip 10 can always be reliably supported regardless of the cross-sectional change of the variable extruder as in the first embodiment. Accuracy can be reliably increased.
[0043]
