体１７６が実質上変形することはない。As described above, after the preform 176 is delivered from the preform supply means 12 to the vertical mandrel 190 of the tensile ring forming and bonding unit 52, the tensile ring forming and bonding unit 52 continues to rotate, and the preform pot Receiving area C
When it reaches the angular position of approximately 25 degrees from the angle, the prism 78 starts to further descend as is clear from FIG. 7, and the preformed pot receiving area C
The lowering of the prism 78 is maintained until the angular position is approximately 45 degrees. When the prism 78 is lowered, the upper mandrel member 102 can be lowered because its lower end 180 is fully engaged with the upper end 184 of the lower mandrel member 160 that is not raised or lowered, and therefore the elasticity of the spring member 104 is It rises relative to the prism 78 against the biasing action. On the other hand, the upper winding tool 98 descends together with the prism 78, and the inner peripheral edge of the lower surface of the upper winding tool 98 comes into contact with the upper edge of the preformed body 176 fitted into the vertical mandrel 190,
The preform 176 is lowered along a vertical mandrel 190. When the upper winding tool 98 descends to a predetermined position,
As a result, the lower edge of the preformed body 176 that has descended comes into contact with the inner peripheral edge of the upper surface of the lower winding tool 136, and at this point, the lowering of the upper winding tool 98 is completed. Therefore, the preformed body 176 is not substantially deformed between the upper winding tool 98 and the lower winding tool 136 due to the downward pressure of the upper winding tool 98 .

When turning over an angular range of 0 degrees, that is, when turning from an angular position of approximately 45 degrees to an angular position of approximately 65 degrees when viewed from the preformed pot receiving area C, the prism 78 rises, and The upper winding tool 98 is also returned to its original position. At this time, the upper mandrel member 102 descends relative to the prism 78 due to the elastic biasing action of the spring member 104, but does not rise or fall relative to the lower mandrel member 160. Furthermore, the preformed body 176 that has descended to a position where its lower edge abuts the inner peripheral edge of the upper surface of the lower winding tool 166 is maintained at that position without rising along with the upper winding tool 98.

It moves up and down in exactly the same way corresponding to the up and down movement of No. 8. Therefore,
The arm 146 of the arm 140 often pivots about the pin 144. However, while the tensile ring forming and bonding w knit 52 passes through the curved area F, the prism 78 is not raised or lowered, but the sliding lever 166 of the 7177 means 140 is raised and then lowered. That is, while the tension forming and joining unit 52 is pivoting from an angular position of approximately 100 degrees to an angular position of approximately 165 degrees when viewed from the preform pot receiving area C, the sliding lever 166 is raised and then the preform pot is rotated. While pivoting from an angular position of approximately 135 degrees to an angular position of approximately 170 degrees as viewed from the receiving area C, the sliding lever 166 descends to its original position. As can be seen by comparing FIGS. 6 and 11, when the slide lever 166 of the hammer means 140 is raised, the arm 146 is moved from the pin 14.
Turn counterclockwise around 4 (see Figure 6).

亘って前成形体１７６の外面に充分緊密に重合する。When the tension forming and joining unit 52 is at an angular position of approximately 165 degrees when viewed from the preform pot receiving area C, the arm 146 is pivoted to the position shown in FIGS. 11 and 12 by raising the sliding lever 166. . As a result, the tip of the hammer tool 156 attached to the tip of the arm 146 passes through the opening 172 provided at the lower end of the sliding plate 118 and protrudes inward in the radial direction.
The free end 210 of the tear-off strip 206 and the preform 176 are struck and pressed against the vertical mandrel 190. Therefore, the tip of the hammer tool 156, that is, the striking surface, is formed into an arcuate surface with a curvature corresponding to the curvature of the outer peripheral surface of the vertical mandrel 190. Therefore, due to the impact of the hammer tool 156, the free end 210 of the tear-off tab piece 206 of the container lid 192, which had been flat until then, has a curvature that is substantially the same as the curvature of the outer peripheral surface of the vertical mandrel 190. Therefore, it is curved in the width direction with substantially the same curvature as the curvature (longitudinal curvature) of the outer surface of the preformed body 176, and is sufficiently tightly overlapped with the outer surface of the preformed body 176 over the entire width direction.
