The method for producing a strip of material with an integrated electronic component comprises the following steps according to the present invention: feeding a material web, cutting a first piece of material from the material web, lifting the first piece of material, applying an electronic component to the material web, once again feeding the material web with the electronic component located on it, cutting a piece of material from the material web to obtain a second piece of material on which the electronic component is located, and applying the first piece of material to the second piece of material so that the electronic component is accommodated between the first piece of material and the second piece of material.

A topping sheet forming method includes: a division step of cylindrically winding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yarns, to form an original fabric roll and cutting off the weft yarns in predetermined widthwise positions by using a wire wound on the original fabric roll in a predetermined winding angle range to divide the textile original fabric into narrow textile original fabrics; and a topping step of topping at least one surface of each of the narrow textile original fabrics with unvulcanized rubber.

A guidance and maintenance machine (100) includes a guide roller (102) and an application roller (104), each having a plurality of respective grooves (102a, 104a) defined on a respective circumferential surface (102b, 104b). The guidance and maintenance machine includes at least one preparation comb (200) having a support (202) with an upper surface (202d) from which a plurality of teeth (204) extend. The teeth, with a predetermined uniform height, are aligned in parallel along a length of the support and are positioned at a pitch between them in correspondence with corresponding grooves (102a) of the guide roller (102) so that the comb (200) feeds filaments (50) from a supply creel (304), where the filaments are stored, to the guide roller (102) at a predetermined pitch positioning outside the guide roller.

A guidance and maintenance machine (100) includes an upper guide roller (102) and a lower guide roller (104), each guide roller (102, 104) having a plurality of circumferential grooves (102a, 104a) defined on a respective circumferential surface (102b, 104b). At least one preparation comb (200), provided in correspondence with each guide roller (102, 104), has a support (202) with an upper surface (202d) from which a plurality of teeth (204) extend. The teeth are aligned and parallel along the length of the support. The teeth attributed to the upper guide roller are positioned at a pitch therebetween in correspondence with the grooves of the upper guide roller, and the teeth attributed to the lower guide roller are positioned at a pitch therebetween in correspondence with the grooves of the lower guide roller.

The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.

A cross-head die assembly for use with an extruder is described. The cross-head die assembly includes: an inlet section having an inlet for communicating flow from the extruder to one or more flow channels formed in a support block; and an outlet, a removably mounted die located at the outlet and in fluid communication with the one or more flow channels; said support block further comprising an interior slot extending from a first side of the support block to an outlet passageway; a removable cassette positioned in the interior slot, wherein the front end of the removable cassette is positioned to seal the outlet passageway of the slot so that the slot is isolated from the flow.

The invention relates to a process for producing an extruded sulfur-crosslinkable rubber mixture, comprising the following process steps: A) producing a sulfur-crosslinkable rubber mixture by means of a mixer or providing a sulfur-crosslinkable rubber mixture, where the temperature of the sulfur-crosslinkable rubber mixture is less than 35° C., B) contactlessly adjusting the temperature of the sulfur-crosslinkable rubber mixture produced or provided in step A) to at least 40° C. in a temperature adjustment unit, C) measuring the temperature of the rubber mixture in the temperature adjustment unit and D) feeding the sulfur-crosslinkable rubber mixture that has been measured in step C) into an extrusion unit at a temperature of 35° C. or more and extruding the fed rubber mixture in the extrusion unit. The invention further relates to an apparatus for performing the process and to the use of the apparatus.

A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.
