AI Technical Summary
Technical Problem
Existing tire manufacturing devices face challenges in accurately correcting the axial positional deviation of cylindrical bodies due to wear and deformation of drive mechanisms, affecting tire quality.
Method used
Incorporation of a linear encoder to detect the axial position of cylindrical bodies, with a control unit that calculates and corrects positional deviation based on detected data, ensuring precise positioning without being affected by wear and deformation.
Benefits of technology
Accurate correction of axial positional deviation improves the quality of molded green tires and subsequently vulcanized tires by maintaining precise positioning of unvulcanized tire components.

Abstract
To provide an apparatus for a tire capable of accurately correcting the positional shift of a slidably moving cylindrical body with respect to a target position, and a method for manufacturing the tire using the apparatus for the tire.SOLUTION: When a pair of drum body side 1Ab and side 2a constituting a shape drum side 2a are slid and moved along a cylinder axis direction and positioned at a preset target position, a driving motor side 4b is controlled by a control part 7 based on the position of the target position, and each drum body side 2a is slid and moved and positioned. A detection result obtained by the linear encoder 8 detecting the position of each positioned drum body side 2a in the cylinder axis direction is input to the control unit 7, a positional deviation amount between the detection result and the target position is calculated, and the green tire G molded by laminating the unvulcanized tire member M on each drum body side 2a in which the positional deviation in the sliding direction with respect to the target position is corrected based on the positional deviation amount is vulcanized to manufacture the tire T.SELECTED DRAWING: Figure 5
