The invention discloses a tire building device and a tire building method. The tire building device includes a lateral-longitudinal-orthogonal 1 rail unit, a transferring ring, a carcass application unit, a bead placement unit, a belt application unit, a building unit, a shaping unit, and a tire unloading mechanism; the lateral and longitudinal orthogonal rail unit divides the tire building device into four areas, and also establishes the connection between the units through the transferring ring. The tire building method, including: 1) adhere the bead and tire carcass compound and then sent to the building unit; 2) send the belt compound to the building unit, 3) compound the carcass compound and belt compound into a carcass and sent to the shaping unit; 4) wind the carcass around the tread to form a green tire and sends it to the tire unloading mechanism for disassembly.

An apparatus and a method to control manufacturing and feeding of semifinished products in a tyre building process, includes detecting at least one first image representative of a semifinished product; dividing the at least one first image into a plurality of first sub-parts, wherein each one of first sub-parts is composed of a plurality of first portions, each one associated with a respective brightness value; defining a first threshold for the brightness values; making a first comparison between the brightness values of the first portions and the first threshold; as a function of the first comparison, determining for each one of the first sub-parts a first operative parameter representative of a total area occupied in each first sub-part by the first portions associated with a brightness value smaller or greater than the first threshold; making a second comparison between each one of the first operative parameters and a second threshold; and causing the generation of a first notification signal as a function of said second comparison.

A topping sheet forming method includes: a feeding and division step of feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yams, and cutting off the weft yarns in predetermined widthwise positions to divide the textile original fabric into a plurality of narrow textile original fabrics; a calender step of topping, with unvulcanized rubber, at least one surface of one narrow textile original fabric out of the divided narrow textile original fabrics; and a wind-up step of winding up the other narrow textile original fabrics out of the divided narrow textile original fabrics.

A device for loading at least one carcass drum with tire components for green tires, a tire-building machine and a method for producing green tires. The device for loading the at least one carcass drum with tire components includes a placing device, which can move linearly in the horizontal direction, for delivering material components to a carcass drum, wherein the at least one placing device can be moved vertically so that a vertical movement in addition to or alternatively to the horizontal movement is facilitated and, in this way, the ply server is designed to be self-opening.

The invention relates to a supply installation (22) for a site (10) for producing rubber products from rubber blocks of rubber mixtures of predetermined weight and volume, characterized in that the supply installation includes: an input station where the supply installation performs a process of entry of empty bins (B.sub.V) for receiving, during a picking process, rubber blocks identified to satisfy a rubber product production campaign; a discharge station where the supply installation performs a process of discharging full bins (B.sub.P) containing the picked rubber blocks; a supply means that manages the transport of the empty bins and the full bins to the supply installation; and a picking station that performs a process of picking the rubber blocks grouped in a container according to the status of the current rubber product production campaign.

Disclosed is a filler-raising device that raises a filler upright to couple the filler with a bead core. The filler-raising device includes a balloon that raises the filler upright toward the bead core and an air controller that supplies air into the balloon and draws air out of the balloon.

A system and method is provided for reading and/or writing data from/on RFID tags of tires conveyed on a conveyor belt in a conveyance direction, wherein each tire is fitted with a respective RFID tag storing a univocal identifier of said tire. An antenna is installed over or nearby the conveyor belt and configured to radiate RF signals toward a footprint area on the conveyor belt and receive backscattered RF signals from said footprint area. A reader is connected to the antenna to operate the latter in transmission and reception. A preliminary calibration step is applied to the reader and a reading and/or writing step is carried out by operating the calibrated reader.

A blank stand for receiving and/or temporarily storing at least one tire blank and to a logistics system for realizing a flow of material of tire blanks to tire manufacturing plants with at least one blank stand, wherein the blank stand and the further components of the logistics system are designed such that handling and transport functions are supported in different height levels relative to a floor level of the hall.

In the building of a carcass structure for tires of vehicle wheels, the step of reinforcing with a loop at least one annular anchoring structure associated at the axially opposite end edges of a carcass ply is carried out on at least one radially expandable/contractable service drum and includes the steps of: setting the service drum to a predetermined radial dimension selected according to the fitting diameter of the tire to be manufactured, depositing the loop on the service drum, loading the annular anchoring structure onto the service drum in a radially outer position with respect to the loop, radially expanding the service drum up to lock in position the annular anchoring structure, rotating the service drum about a longitudinal axis thereof and, during the rotation, turning the loop up about the annular anchoring structure.

Provided is a tire transport method for a tire inspection system in which a tire transported from the upstream side is fastened by an upper rim and a lower rim, and a measurement is performed, wherein the method includes transport stem in which a transport mechanism having a pair of transport units split in the width direction transports the tire to a fastening position for fastening, and a parting step in which the pair of transport units is parted in the width direction, such that it is possible for the lower rim to pass between the pair of transport units.
