Abstract

PURPOSE:To prevent flattening of a plastic pipe and to obtain a circular section by a method wherein the plastic pipe is drawn out of a first drum and wound round a second drum such that the surface of the pipe different from that having been circumscribed over the first drum by a given angle is circumscribed over the second drum. CONSTITUTION:A plastic pipe 2 wound round a first drum 1 is drawn out of the drum 1 and then wound round a second drum 3 such that the surface of the pipe different from that having been circumscribed over the first drum by 90 degrees is now circumscribed over the second drum. With this, the pipe 2 wound round the drum 1 in a sectional shape A is now wound round the drum 3 in a sectional shape B. Accordingly, the pipe 2 undergoes deformation at this time in the direction different from the previous one by 90 degrees to reform the flattening deformation occurred during winding round the drum 1, so that the pipe has a substantially circular section C when drawn out of the drum 3. In this way, it becomes possible to reform the flattening deformation occurred due to the drum 1 and obtain a substantially circular section when the pipe is drawn out of the drum 3.

Description

【発明の詳細な説明】 本発明はプラスチックパイプの偏平防止方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing flattening of plastic pipes.

特徴とするものである。The plastic pipe flattening prevention method according to the present invention includes the first
The method is characterized in that the glass snack pipe wound around the drum is pulled out and wound around the second drum so that the side that is 90° different from the side that was wound around the first drum is wound around the second drum. It is something.

ける。As shown in FIGS. 1 and 2, in this embodiment, the plastic pipe 2 wound around the first drum 1 is pulled out from the first drum 1 and transferred to the second drum 3. 1
Wrap the drum 1 on a side that is 90° different from the side that was wrapped around the drum 1.

うに断面はぼ円形になる。In this way, the glass fibers 2 that had been wrapped around the first drum 1 with a cross-sectional shape as shown in Figure 3 (B) will be transferred to the second drum 3 as shown in Figure 3 (B). It can be wound with a cross-sectional shape like this. Therefore, at this time, the plastic pipe 2 is given a 90° different deformation, the flat deformation that occurred when it was wrapped around the first drum 1 is corrected, and when it is pulled out from the second drum 3, it is shown in FIG. As shown in Q, the cross section is approximately circular.

うことができる。As explained above, in the present invention, the plastic pipe that was wrapped around the first drum is wrapped around the second drum so that the surface that is 90° different from the surface that was wrapped around the first drum is wrapped around the second drum. Since it is wound, the flat deformation caused by the first drum is corrected, and when it is pulled out from the second drum, it can have a substantially circular cross section. Therefore, according to the present invention, it is possible to supply a plastic pipe having a substantially circular cross-sectional shape.
