Provided are a method and device for forming a cylindrical member for accurately forming belt-like members into a cylindrical shape without meandering. A pre-winding position sensor detects a position of a member reference line extending in a longitudinal direction of a belt-like member along the entire length of the belt-like member in the longitudinal direction thereof before the belt-like member is placed on a transport conveyor belt, transported to a forming drum, and wound around the forming drum. The belt-like member is wound around the forming drum and formed in a cylindrical shape while the forming drum is relatively moved in the drum width direction with respect to the transport conveyor belt by a controller and the member reference line, based on the detected data and a position data of the drum reference line orthogonal to the drum axial center of the forming drum.

The supply facility comprises a preparation station (32), said preparation station comprising a manipulator arm (70), and at least one motor (53), the preparation station and the unwinder being distinct from the green tire manufacturing machine. The method comprises the following successive operations: loading the reel onto the unwinder; positioning the end of the product wound on the r?el; arranging the end of the product in such a way that it is laid on a dispenser of the unwinder; and transferring the reel from the preparation station to the green tire manufacturing machine.

Method for manufacturing a green tire by winding a carcass reinforcement ply onto a tire-building drum on which a number of profiled elements are axially spaced apart one from one another and have a given thickness of which the meridian line has a curved profile are laid, wherein: the front edge of the carcass reinforcement ply is grasped with the aid of a transport device having a chassis that supports a transverse row of ply gripping pads, the carcass reinforcement ply is transferred between a supply station and drum, the front edge of said ply is laid on the tire-building drum, said transport device is withdrawn, an applicator roller having a deformable profile is applied to the front edge of said ply and pressure is exerted in the radial direction across the width of said ply, and said drum is made to rotate. At least one of the gripping pads mounted in a movable manner with respect to the adjacent pads between a position in which all of the pads are located in a single plane and a second position in which at least said pad is vertically offset with respect to the adjacent pads to adapt the profile of said transverse row of pads to the curved profile of the meridian line of said second laying surface.

A tire building method, in particular for strip-winding, includes the step of: providing a choice between a production mode for building a tire component and a test mode for obtaining test measurements, wherein the choice is provided prior to executing the test mode; wherein at least one or more building parameters is set prior to the building of the tire component based on test measurements performed on a test strip during the test mode. Also disclosed is a tyre building system and a measurement tool.

A joining state determination method includes: acquiring member front end imaging data of a band-shaped member; acquiring member joint imaging data of the band-shaped member; calculating a matching rate indicating a degree of coincidence of the acquired member joint imaging data with member front end registration data registered based on the acquired member front end imaging data; and determining that the longitudinal ends of the band-shaped member are properly joined, in the case where the calculated matching rate is either not greater than a predetermined threshold or less than the predetermined threshold.

A method for managing the continuous feeding of an elongate element wound on reels to a station for building a tire, wherein the elongate element is continuously supplied from an unwinding device of successive reels. When the terminal end of the elongate element wound on a first reel leaves said first reel, the method provides for: the first reel to be moved away from the unwinding device on a first movable carriage; a second reel, successive to the first reel, and mounted on a second movable carriage, to be positioned in place of the first reel; and the terminal end of the elongate element previously wound on the first reel, to be joined to the starting end of the elongate element wound on the second reel.

Systems and methods for improving the uniformity of a tire by separating uniformity contributions associated discrete effects, such as effects resulting from product joints, from continuous effects are provided. For instance, uniformity contributions associated with the product joints are determined by analyzing a uniformity waveform to process the uniformity waveform into one or more continuous components and at least one joint component. Knowledge of the uniformity contributions associated with product joints in the tire can be used, for instance, to make structural improvements in the manufacture of the tire, to actively manage the joint-making process, and to perform dynamic correction of joint effects.

Disclosed is a strip applicator, a strip-winding station and method for applying a strip to a strip-winding drum, wherein the strip applicator includes an applicator member applying the strip to the strip-winding drum at an application position and a supply section receiving the strip in an input direction at a supply position and supplying the strip to the applicator member in an output direction. The applicator member is movable in an offset direction transverse to the output direction to offset the application position relative to the supply position. The supply section has an input member at the supply position for receiving the strip in the input direction and an output member for outputting the strip to the applicator member in the output direction. The output member is movable relative to the input member from a start position towards an offset position in the offset direction.

A supply apparatus of tire material members includes a feeder that feeds out first and second continuous material members from which first and second material member is to be cut out, respectively, a conveyer that conveys the first and second continuous material members, a cutter that cuts the first and second continuous material members at a cutting position extending perpendicularly to a conveyance direction every time when the first and second continuous material members are conveyed by a predetermined length, a position detector that detects positions of the first and second continuous material members during a conveyance by the predetermined length from the cutting position, and a position adjuster that, during the conveyance by the predetermined length from the cutting position, adjusts conveyance distances of the first and second continuous material members based on the detected positions of the first and second continuous material members.
