The friction resistance of the transparent film is lowered in this way and the stable transportation in the transporting path of the image forming device is possible. After the toner images are fixed on the transparent film, the roughened surface is smoothed and, therefore, the scattering of incident light does not arise when the film is loaded in a projecting device. The non-image parts which are ought to be intrinsically white are reproduced white. The problems that gray colors are mixed in the color image parts and both saturation and lightness decrease are solved.

Title: Manufacture of pneumatic radial tire
Inventor: NAGUMO NOBORU
IPC: B29D30/06
Filed: 1990-11-09
Abstract: PURPOSE:To prevent the disturbance of the cords of a carcass layer by bonding a rubber sheet irradiated with electron beam over the range from a shoulder part to a side part to one of the inner and outer side surfaces of the carcass layer over the periphery of a tire. CONSTITUTION:When a carcass layer 2 is formed by winding a carcass sheet around a molding drum in a green tire molding stage, a rubber sheet preliminarily irradiated with electron beam is bonded to one of the inner and outer side surfaces of the carcass layer 2 over the periphery of a tire. Since the rubber sheet is slightly advanced in curing because of the irradiation with electron beam, even when the carcass cords over the range from a shoulder part 3 to a side part 4 expands at the time of the vulcanization and molding of the tire, the movement of them is suppressed. Further, since larger tensile force is applied to the outside of the carcass layer 2 as compared with the inside thereof when internal pressure is applied to the green tire, when the rubber sheet 1 is set to the outside of the carcass layer 2, the tension thereof can be effectively absorbed.
