- a target number of cords to be driven into one tire is set for each tire size, and the target number for each tire size is determined by the number of inches of the corresponding tire size.
- the divided quotient is calculated, an average integer value of the calculated quotient for each of the evening sizes is calculated, and the average integer value can be used as the number of cords to be driven into the narrow member.
- the number of cords to be driven into the narrow member is determined based on the target number of codes to be driven into one tire for each tire size.
- the number of cords to be driven into one tire of each tire size of the tire component is constant at the target number or very close to the target number.
- the target number of cords to be driven into one tire is set for each cord type, and the number of cords to be driven into the narrow member can be determined for each cord type.
- the number of codes obtained by subtracting 1 from the number of cords described above is driven into the narrow member, and the narrow member adjacent to the width direction is replaced by the one cord at the end of both narrow members. It is preferable to join them so that they overlap. In this case, the terminal end portion where the adjacent narrow member pieces are overlapped is formed such that the thickness decreases toward the front end.
- FIG. 1 is a schematic plan view of a ply manufacturing apparatus suitable for carrying out the method for forming a corded tire component according to the present invention.
- FIG. 2 is a side view of FIG.
- FIG. 3 is a schematic side view of a main part showing a process of sequentially joining narrow member pieces.
- FIG. 4 is a flowchart showing a procedure for determining the number of cords to be driven into the narrow member and the width.
- Fig. 5 shows the appearance of the driving cord assuming a ⁇ -inch width narrow member. It is an expanded sectional view of a width
- FIG. 6 is an enlarged sectional view showing the actual positional relationship of the joining of the narrow member pieces.
- FIGS. 1 to FIG. 3 show a schematic configuration of a manufacturing apparatus thereof.
- Reference numeral 10 denotes an extruder for tire material.
- the extruder 10 has a cylinder 11 having a screw (not shown) provided therein.
- the cylinder 11 is supplied with various materials from a hopper 12. You.
- the material put into the hopper 12 is a ply rubber material, and the ply rubber material put into the cylinder 11 is conveyed to the tip of the cylinder 11 while being kneaded by the rotation of the screw. It is guided to a die 14 having a predetermined shape of one head 13.
- an insulator 15 is arranged behind the die 14, and a plurality of codes unwound from a plurality of reels 16 arranged further behind.
- (Steel or resin cords) 1 are arranged in a horizontal line by an inserter 15 and supplied to the die 14 from the rear.
- the arrangement of the cords 1 is coated with rubber, and the cords are formed by the die 14 into a predetermined shape.
- the narrow member 2 is continuously formed.
- the narrow member 2 containing the cord having a certain width is extruded from the die 14 and is formed continuously.
- the narrow member 2 is wound around the pull drum 17 and pulled out, and is placed between the pull drum 17 and the pair of idle rollers 19. It is sent to the belt conveyor 25 through the formed festoon 18.
- the belt conveyor 25 has a configuration in which a conveyor belt 28 is stretched between the front and rear rollers 26 and 27, and the narrow member 2 is cut into a fixed length by a force roller 20 to form a narrow member piece 3. It is supplied to a predetermined position on the upstream side of the conveyor belt 28 from a direction perpendicular to the conveying direction of the conveyor belt 28.
