も少なくなるためであると考えられる。As is clear from the table, according to the examples, the productivity of the melt sealing process according to the present invention has improved dramatically (note: proportional to the running speed)
Not only that, but the holes at both ends of the hollow cage rod are completely blocked, and there is almost no stringing. This is because the melted resin at both ends of the hollow cage rod has a low viscosity because it is at a high temperature, so it easily flows into the hollow part and easily breaks before becoming stringy.
Further, it is thought that this is because a part of the portion that is pressed and melted by the heating member according to the present invention is thermally decomposed and vaporized, so that the curling up of both ends of the screen rod is eventually reduced.

全なものが発生し易く、信頼性に乏しい。On the other hand, in the case of each comparison side, where the length of the heating member is long, but the temperature during heating is about 400°C, the traveling speed of the nori screen material should be increased. Therefore, the sealing speed can be increased to some extent. however,
At this time, the holes at both ends of the hollow cage rod are likely to be incompletely closed by melt sealing, and are therefore unreliable.

簀を取得できない。In addition, since the viscosity of the resin melted by the heating is high and there is almost no decomposition and vaporization of a part of the resin, both ends of the hollow cage rod that is slid into pressure contact with the heating member may be bent or the surface of the heating member may be The molten resin adhering to the pipe line is irregularly picked up by the end of the pipe line and solidified in a stringy shape at the end.Furthermore, if the temperature of the heating member is as low as 350°C, the treated seaweed cage Not only are the holes at both ends of the hollow cage rods constituting the layer material hardly sealed, but the string-like resin mentioned above adheres to the ends of the pipe lines, resulting in a seaweed cage with both ends melt-sealed as desired.

。However, when the heating member according to the present invention (particularly one in which the cross-sectional shape of the sliding surface is groove-shaped) is used, the curling of both ends of the hollow cage rod due to the pressure melting and sliding of the sacrificial material for the seaweed cage can be almost eliminated or extremely reduced. As a result, even if the temperature of the heating member is about 400° C., it is possible to efficiently manufacture a seaweed cage in which both ends of the tube line are completely melt-sealed and the shape of the melt-sealed portion is good.

る。Furthermore, as is clear from the table, the heating member according to the present invention has a significantly faster temperature increase rate than that of the comparative example, so that it is possible to efficiently operate the nori welding end welding device, and the heating member according to the present invention It also saves power consumption compared to using .
本発明に係る加熱部材は、比較例のものに比較して構造
が簡単なため経済的に製造でき、かつ、故障も少ない。The heating member according to the present invention has a simpler structure than that of the comparative example, so it can be manufactured economically and has fewer failures.
