ズに行うことができなくなるという欠点があった。"Prior Art" Conventionally, a roll of synthetic resin string for binding has been manufactured by a process of melting a polyolefin synthetic resin, extruding it, cooling it, stretching it, cooling it, and winding it up. However, in such a process, the stretched string shrinks over time due to the influence of outside temperature, etc., and the shrinkage progresses even in the wound state, so that the string 2 is attached to the core 1 as shown in Fig. 1. When it is wound up into a roll, the core is crushed and deformed, and as shown in Figure 2, there is no core and the string 2 is separated from the center.
In the case of a roll that lets out strings, the hole in the center becomes deformed, resulting in a situation like that shown in Figures 3 or 4, which has the disadvantage that the string cannot be drawn out smoothly. Ta.

から巻き取るものである。Therefore, annealing (heat treatment) has been adopted as a means to reduce the shrinkage after stretching, but there is a problem in the timing of annealing. That is, currently, the process is melt extrusion, cooling, stretching, cooling, annealing, cooling, and winding. This process involves annealing and then winding.

方法である。The present invention relates to a method for producing a coreless roll of polyolefin synthetic resin string, in which a synthetic resin string stretched at a required stretching ratio is wound around a core under an appropriate tension that does not crush the core, and the string is heated at υ, 60°C to 60°C. At a temperature of 120℃ [(heat treatment temperature)
(60t?:): This is a method for producing a coreless roll of synthetic resin string for binding, characterized in that annealing is carried out at a waiting time of 40 to 200 lx, and the core is removed after cooling.

のがある。"Effects" The present invention is characterized by melt extrusion, cooling, stretching, and winding into a core.
- Annealing - Cooling - Removal of the core. Since annealing is performed after winding into the core, it is possible to prevent collapse due to residual tension when tension is applied during winding υ. It is possible. Therefore, it is possible to maintain the normal shape of the coreless roll, and there are many advantages to the manufacture of the coreless roll.
