It is used. If the outer peripheral surface of the lower winding layer is formed of yarn, roving or cross tape, the outer peripheral surface of the lower winding layer becomes inhomogeneous. Cracks are likely to occur in the outer cylinder or the adhesive layer, starting from the yarn, roving or cloth tape fibers present on the surface of the layer. Therefore, it is preferable that at least the outer peripheral surface of the lower winding layer is formed of a nonwoven fabric.

It will be. Therefore, the work of winding the nonwoven fiber aggregate becomes easy.
- the lower winding layer may have a single-layer structure or a laminated structure.
- the lower winding layer has a laminated structure including an inner layer and an outer layer.
- the step of forming the lower winding layer includes forming an inner layer of the lower winding layer on the outer periphery of the roll core, and forming an outer layer on the inner layer.
- the outer layer is a non-woven fiber aggregate impregnated with a thermosetting resin.
- the inner layer of the lower winding layer is formed by impregnating a liquid thermosetting resin into a thread, roving or cloth tape made of any one of inorganic fibers and organic fibers, and winding it around a roll core.
- a liquid thermosetting resin into a thread, roving or cloth tape made of any one of inorganic fibers and organic fibers, and winding it around a roll core.

- thermosetting resin material that impregnates the nonwoven fiber aggregate and the binder that binds the fiber material, it is possible to obtain excellent strength without impairing the physical properties of the lower winding layer. it can. In this sense, it is preferable that both the thermosetting resin material and the binder be epoxy resin-based materials.

Since the nonwoven fiber aggregate has a longitudinal tensile strength of 50 N / 15 mm or more, the tape made of the nonwoven fiber aggregate has sufficient tensile strength when wound around the roll core. You. Therefore, the winding operation becomes easy. On the other hand, if the tensile strength of the tape composed of the non-woven fiber aggregate in the longitudinal direction is lower than this, the fibers constituting the tape may become loose due to the tension when wound around the outer periphery of the roll core, or the tape may become thin. It may be cut or cramped, making it difficult to wind.
- the nonwoven fiber aggregate preferably has a basis weight of 30 gZm 2 or more and 100 g / m 2 or less. If the basis weight of the nonwoven fiber aggregate is less than 30 gZm 2, the strength of the tape made of the nonwoven fiber aggregate will be low, and the tape may be cut off by the tension when wound around the outer periphery of the roll core. Further, when the basis weight of the nonwoven fiber aggregate is small, the thickness of the tape is small, so that it is necessary to increase the number of times of winding the tape to make the lower winding layer a predetermined thickness, which is troublesome. On the other hand, if the basis weight of the nonwoven fiber aggregate is too large beyond 100 g / m 2 are likely out uneven thickness of the lower ⁇ , to form a uniform bottom ⁇ it becomes difficult result, The strength of the resin roll may be reduced.

- thermosetting resin material impregnated in the nonwoven fiber aggregate there is a method of heating the nonwoven fiber aggregate.
- the heating of the nonwoven fiber aggregate can be performed by a hot air device or a heater.
- the viscosity of the thermosetting resin material may be reduced by a method other than heating.
- thermosetting resin material When the viscosity of the thermosetting resin material is reduced by heating, the reaction of the thermosetting resin material proceeds before the operation of winding the nonwoven fiber aggregate around the outer periphery of the roll core is completed.
- heating to high temperature It is preferable to lower the temperature immediately after impregnating the nonwoven fiber aggregate with the liquid thermosetting resin material. From such a point, as the heating means, a heating device is locally installed at least during the transfer of the nonwoven fiber aggregate and the winding around the roll core.
