摘要:
The present disclosure is directed to a process and an apparatus for cutting a continuous rubber-covered belt in a process for building tyres for vehicle wheels, wherein the apparatus comprises 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 comprises: 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.

In building tyres, an intermediate portion of a carcass structure is built at a time on a respective forming drum within an intermediate forming line. The forming drum with the intermediate portion of the carcass structure is made available at a first transfer location. The intermediate portion of the carcass structure is completed through n completion locations with n≥1 and then transferred for the subsequent assembling with a crown structure to a second transfer location. At an operating moment in which the first transfer location is occupied by a forming drum coming from the intermediate forming line or intended for the intermediate forming line, from one to n locations selected from the n completion locations and the second transfer location are occupied by respective forming drums.

Method for checking the formation of beads of tyres including: arranging a carcass sleeve with formed beads with the carcass sleeve in rotation, acquiring at least an image of a circumferential portion of external surface including the respective edges of the end flaps turned up; processing the image in order to determine a circumferential trend of the axial distance of each edge from an axial reference plane; and detecting possible defects of the beads as a function of such trend.

Method, process and plant for building tires for vehicle wheels wherein: in a service position of a carcass structure building line, a forming drum is associated with a pair of support elements including a first support element and a second support element; the forming drum is moved, associated with the pair of support elements, in a deposition line in the carcass structure building line; and the forming drum is transferred from the deposition line to a subsequent work station of the carcass structure building line. The transfer from the deposition line to the subsequent work station includes dissociating the forming drum from the second support element, keeping the forming drum associated with the first support element; transferring the forming drum, associated with the first support element and dissociated from the second support element, to the subsequent work station; dissociating, in the subsequent work station, the first support element from the forming drum, leaving the forming drum in the subsequent work station; and transferring the first support element, dissociated from the forming drum, into the service position.
摘要:
A method for managing a carcass structure building line, a plant and a process for building tyre carcass structures, wherein the plant includes a carcass structure building line provided with a plurality of stations including an unloading station and n building stations. A group of forming drums being processed includes m forming drums being processed defining a first size of carcass structure being processed. Three groups of entering forming drums include respective entering forming drums, defining a second size of carcass structure being processed. A pair of support elements being processed includes a first and a second support element being processed and three pairs of entering support elements respectively include a first and a second entering support element. The invention also relates to a method for managing a carcass structure building line.
