Abstract

PURPOSE:To form a helically formed part in which no flute-like recess generates and which at the same time has high bonding strength between molding materials, by a method wherein the molding material is wound round a rotating take-up shaft just after being extruded in a specified shape in order to cool and solidify. CONSTITUTION:Molding material 2, in the cross-section of which the breadth E of the surface 10 directly winding onto the surface of a take-up shaft is made smaller than the breadth F of the outside surface 11, is continuously extruded through the orifice 1 of an extruder. Just after being extruded, the molding material 2 is wound up round the take-up shaft 3 rotating at the position nearly normal to the molding material 2. The taken-up molding material 2 is immediately cooled and solidified. At this stage, various kinds of stresses are applied to the molding material 2, resulting in widening the surface 10 contacting with the take-up shaft 3 laterally and, on the contrary, shrinking the breadth of the outer peripheral surface 11 which does not contact with the take-up shaft 3. As a result, no flute-like recess generates in a formed part and at the same time the bond area of the joining surfaces 14 of the molding material 2 among one another becomes larger and accordingly, the bonding strength between the molding materials is enhanced.

強度も十分に保たれる。Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a partial cross-sectional view for explaining the process of winding up the molding material extruded from the extrusion molding machine of the example on a rotating winding shaft and cooling and solidifying it. The nozzle part-2 is an extrusion molding material that is continuously extruded from this nozzle part 1 before being cooled and solidified. Reference numeral 3 denotes a winding shaft for winding the extrusion molding material 2 onto its surface while rotating at a position substantially perpendicular to the extrusion molding material 2. That is, a drive mechanism is configured so that the winding shaft 3 rotates in the direction of the arrow in the figure and moves in the longitudinal direction thereof. Furthermore, the winding speed of the winding shaft 3 is adjusted to maintain an appropriate relationship with the extrusion speed of the extrusion molding machine so that an appropriate tensile load is applied to the molding material to be wound. Further explanation will be added to FIG. FIG. 2 is a cross-sectional view showing the cross-sectional shape of the extruded molding material 2 immediately after being extruded from the mouth l of the extrusion molding machine, and FIG. 3 is a cross-sectional view showing the cross-sectional shape of the molding material 2 after being wound up. It is a partially sectional view. That is, the circular dimension E of the side 10 to be wound around the winding shaft 3
is smaller than the circular dimension F of the outer surface 11, and the circular dimension G of the side 10 to be wound around the winding shaft 3 and the circular dimension of the outer surface ii are set as shown in FIG. The circular dimensions H are made to be approximately equal, and the gaps generated at the joints 13 between the wound molding materials 2 are minimized as much as possible. That is, when a molding material extruded from a molding machine and having faces 11 and 10 facing each other and having different widths before solidification is wound onto the winding shaft 3, various stresses are applied to the molding material 2 during the dust winding. The surface 10 in contact with the shaft 3 tends to widen, and the width F of the outer peripheral surface 11 not in contact with the reverse winding shaft 3 tends to decrease. Therefore, the opposing surfaces 10 of the molding material 2 immediately after extrusion.
IP is appropriately selected depending on the degree of deformation (degree of collapse) of the molding material 2 due to the tensile load generated by winding the molding material 2. With this configuration, the bonding area of the bonding surfaces 14 between the wound molding materials 2 is not large, and the bonding strength after the winding shaft 3 is removed is also maintained sufficiently.

shows the deformed state of. That is, if the width dimensions B and A of the two facing surfaces 5 and 6 are selected to be equal as shown in FIG. 5 is compressed and expanded, and on the other hand, the outer surface 6Fi on the opposite side contracts under tensile stress, so that a gap 8 is created between the wound molding materials 2.

したがって、この場合は両者の接合点９が小面積となシ
強度上不利となるものである。Therefore, in this case, the area of the joint 9 between the two is small, which is disadvantageous in terms of strength.

Furthermore, it is also possible to mold and solidify extruded products with more complex external shapes.

Therefore, according to the present invention, since there are no streaky recesses in the wound spiral molded part, the appearance and appearance are improved.
