摘要： PURPOSE:To make the groove of a tyre product in a predetermined position even if any rolling occurs in the tyre by setting a cutter to the theoretic cutter cutting position, and calculating the correction moving rate of the cutter by a tyre rolling detecting signal, and then actuating the moving rate correcting mechanism of a horizontal moving table on the basis thereof. CONSTITUTION:In a standard actuation operating unit, a standard program is memorized therein, and according to this, the direction of a cutter 10 is set by making it coincide with the cutting direction by means of a motor 11, and then heated, wherein a tyre 3 is rotated, and further the standard rate moving mechanism of a coming up and down table driving mechanism 8 is driven so as to make a coming up and down table 7 descend in the direction of a Z axis, as a result, the cutter 10 cuts in to the tyre 3. In the case where the rolling of the tyre 3 occurs therein and the center of the tread deflects therefrom, the moving rate correcting mechanism of a horizontal moving table 5 is driven through a correction program in accordance with the detected value of a rolling detector 13, and the horizontal moving table 5 is moved in the direction of a Y axis in order to correct the cutter position; thus, the distance is kept at the position of the groove from the center of the tyre. By the process mentioned above, the desired grooving can be performed even if any rolling occurs in the tyre.

摘要： PURPOSE:To make the groove depth and groove width of a tire constant and to simplify the constitution of a program, by controlling a horizontal moving table and a lift table on the basis of reference moving quantity and allowing the correction moving quantity corresponding to the detection value of a detector to follow the reference moving quantity to correct the moving quantity of a cutter. CONSTITUTION:When a tire 3 is cut up to a predetermined depth (d) from a reference tread surface F according to a reference program, the reference quantity moving mechanism of a horizontal moving table driving apparatus 6 is driven according to the reference program and a horizontal moving table 5 is moved in a Y-axis direction to control the movement of a cutter 10 in a horizontal direction and grooving is performed. A correction program is stored in the memory of a correction operation part on the basis of the vertical vibration of the tire 3. Therefore, when there is vertical vibration E1 by the strain of the treated surface of the tire 3, vertical vibration is detected by a vertical vibration detector 14 and the moving quantity correction mechanism part of a lift table 7 is driven corresponding to the correction value from the correction program based on the detection value and the lift table 7 is raised in a Z-axis direction and the cutter 10 is raised to keep the depth (d) constant.

摘要： PURPOSE:To prescribe the protruding quantity and width of a cutter and to accurately hold the mount position of the cutter with respect to a cutter holder, by using a jig consisting a jig base for holding the cutter holder and a jig block provided with a cutter receiving groove having the dimension equal to the protruding quantity and width of the cutter. CONSTITUTION:A jig block 5 is mounted to a jig base 1 by the clamp bolt 7 inserted through a bolt hole and a cutter receiving groove 8 having the dimension equal to the predetermined protruding quantity and width of a cutter 10 is provided to the center of the surface of the block. A cutter holder 11 having the cutter 10 preliminarily and temporarily clamped thereto by a cutter clamp 18 is inserted in and held between the guide pieces 2, 3 of the jig base 1 and the cutter 10 is inserted in the cutter receiving groove 8 to bring the under surface of the cutter holder 11 into contact with the surface of the block. Next, the cutter clamp 18 is opened left and right to allow the cutter 10 to coincide with the cutter receiving groove 8 and, in this state, the leg part of the cutter 10 is fixed between the cutter clamp 18 and the cutter holder 11 before the cutter holder 11 is detached from the jig.

摘要： PURPOSE:To simplify the controlling program of the position of a cutter tip and at the same time facilitate the cutting of a cutter into tire rubber and the separation of the cutter from the tire rubber by a method wherein the cutter is held at the desired angle to the tread surface of the tire and the cutting edge of the cutter is pivoted so as to align with the direction of a groove and at the same time the cutter is swingably mounted to a cutter holder so as to be able to control the position of the cutter tip through the combination of rectangular co-ordinates. CONSTITUTION:A cutter 5 is adjusted so as to groove a tire 6 at its highest point by shifting a supporting truck 3 along a rail 31 in the direction of the X-axis and at the same time by lowering a supporting stand 32 through a screw shaft 35 with a motor 34 in the direction of the Z-axis. At the end (d) of a groove, where the cutter 5 tends to bite the tire 6, a cutter supporting shaft 43 is pivoted in the direction indicated with the arrow C by means of an actuator 44 so as to swing the cutter 5 only in order to scoop the cutter from the surface of the tire in the direction of cutting-in. Said scooping action allows the cutter to cut into the hard vulcanized tread rubber of the tire, resulting in enabling to easily cut grooves without heating the cutter.
