摘要： When manufacturing a plurality of strip members by cutting a belt-like member along a length direction thereof, the belt-like member having embedded therein a plurality of reinforcement cords arranged parallel to each other, and a weft thread that intersects the reinforcement cords, a captured image showing images of at least the reinforcement cords in a cross section of one end of the belt-like member in the length direction is used to detect the position of the image of each of the reinforcement cords (RC). The number of the actual reinforcement cord (RC) to which each of the images of the reinforcement cords (RC) corresponds is determined on the basis of an interval between the images of the detected adjacent reinforcement cords (RC) in the image and an average cord interval, and a cutting position (Xa) is set.

摘要： A process and an apparatus for cutting a continuous rubber-covered belt in a process for building tyres for vehicle wheels, wherein the apparatus includes a cutting group, in turn comprising: a knife formed by a first half-part and a second half-part and movable along a cutting direction that is tilted with respect to a supply direction of a rubber-covered belt placed beneath the knife. The process includes: lifting a lifting element placed below the continuous rubber-covered belt and at the cutting zone, until a portion of rubber-covered belt is lifted, and lowering the single first-half part of the knife, making it slide with respect to the second half-part.

摘要： A tyre building plant (1; 100) comprises a forming drum (4) and a supply device (10) for supplying an elongated element (3) towards the forming drum. The supply device comprises at least one conveyor belt (11; 101) which extends in a supply direction (X) between a loading region (12), in which the elongated element is loaded on the conveyor belt and an unloading region (13), a control unit (19) for controlling the loading of the elongated element (3) on the conveyor belt (11; 101), at least a first detection element which is fixed with a first portion (20) of the conveyor belt, a sensor (22) which is fixed and independent with respect to the conveyor belt and which detects the position of the first portion (20) with respect to the supply device. The loading of the elongated element on the conveyor belt is performed when the first portion is at a predefined reference distance from the loading region (12).

摘要： A bleeder cord affixing device is made up of an affixing roller extending in a width direction of the treatment member and adapted to be pressed into the treatment member being moved, thereby to be rotated; and a roller moving mechanism that moves the affixing roller to and away from the treatment member. The roller moving mechanism operates to move the affixing roller to a pressed position urged to the treatment member, with a result that the affixing roller is caused to be rotated due to the movement of the treatment member at the pressed position and attaches the rubber member to the treatment member under the pressing force, and then presses the bleeder cords onto the treatment member to continuously affix the bleeder cords onto the surface of the treatment member.

摘要： (N+1) band-like cut members are manufactured by cutting a band-like member N times along the length direction of the reinforcing cords. At such time, cutting positions are set at locations in the width direction of the band-like member from a first end toward a second end, and cuts are made in the band-like member on the basis of the cutting positions. Setting the cutting positions includes: a step A in which cutting positions of the band-like member are set M times (where M is a natural number less than N) for every fixed first number of reinforcing cords; and a step B in which a second number of the reinforcing cords is set within an allowable number range, and the cutting positions are set at (N−M) locations using the second number such that band-like cut members having the second number of reinforcing cords are continuously produced.

摘要： The method and the device serve for aligning a belt strip, which has a middle part and triangular end pieces. The belt strip is wound onto a tire building drum in such a way that the triangular end regions extend next to one another, at least in certain regions. At least one of the triangular regions is changed in its alignment, at least in certain regions. This achieves the effect that the triangular regions extend next to one another on the tire building drum with matching edge contours

摘要： An ultrasonic tuned blade includes a base and a tire cutting edge made of a tool steel having a vanadium content which is at least about 8 percent. For example, the tool steel can have a combined vanadium, cobalt, and tungsten content that is at least about 15 percent. The tool steel can be formed into a simple block via a powder metallurgy process. The simple block can be milled into an ultrasonic tire cutting horn shape comprising a tuned blade including a base and a tire cutting edge. The ultrasonic steel tire cutting horn can be heat treated to provide the tool steel with a Rockwell hardness, for example, of at least about 50 HRC and less than about 64 HRC. The ultrasonic steel tire cutting horn can include a low friction or wear resistant coating.
