Abstract: The method comprises steps during which, by making the cylindrical form rotate in a first circumferential direction, the ply is deposited until the front edge and performs a complete rotation. A point of penetration is marked on the ply on a cutting line, and a cutting blade that is driven in translation is made to penetrate between two wires placed on the cutting line at the point of penetration. The cylindrical form is made to rotate in an opposite second circumferential direction while displacing the cutting blade in a first transverse direction until the cutting blade is disposed at a predetermined and non-zero distance from a first selvedge. Without retracting the cutting blade from the wire gap, the cylindrical form is made to rotate in the first circumferential direction while displacing the cutting blade in an opposite second transverse direction until the cutting blade emerges at a second selvedge.

Abstract: A device (10) for securing an electronic component to a wall of a tire comprises a base (11) that is able to be secured to the wall of a tire and a retaining wall (12), connected to the base (11). The interior surfaces (14, 15) of these elements define a volume (13) able to accommodate the electronic member (100). The base (11) has an opening (18) via which the electronic member is introduced so that when the base (11) is secured to the wall of the tire, the opening (18) is closed by the wall of the tire. The securing device (10) is such that the retaining wall (12) is able to be torn in order to form a fault that allows the electronic member to be extracted and inserted, and such that the retaining wall (12) has a retaining device (19) for a clamping system (20) for clamping the retaining wall (12).

Abstract: A device (10) for securing an electronic member to a wall of a tire casing comprises a base (11) that is able to be secured to the wall (2) of a tire casing, a retaining wall (12), connected to the base (11), the interior surfaces (14, 15) of which define a volume (13) able to accommodate the electronic member, and a clamping system (20) for clamping the retaining wall (12), able to prevent any extraction of the electronic member. The securing device (10) is such that the retaining wall (12), which is able to deform elastically, comprises an opening (18) that allows the electronic member to be extracted and inserted. The retaining wall (12) on its external surface (17) has a retaining device (19) for the clamping system (20). Finally, the clamping system (20) is a single-use system.

Abstract: A device for the laser weld joining of sheet metal strips includes the following elements: a main frame, a laser welding unit including a laser beam generator for welding the sheet metal strips to be joined and a welding head, a clamping jaw unit supported by the frame and used to clamp the sheet metal strips, and a shearing unit for shearing the head and tails of the sheet metal strips to be joined. The shearing unit includes upper blades mounted to a blade holder and lower blades which can move in relation to the upper blades and which are designed to shear a strip, as well as a blade connecting structure fixed to the frame, the above-mentioned welding head being mobile between the blade holder and the lower blades.

Abstract: A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position that is vertically below a reference wheel. The reference wheel is lowered vertically to come into contact and bear on the rotary roller. A distance between an index on a measuring arm of the frame and an articulated column is repeatedly measured during the continuous lowering movement of the roller. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position where the distance equals a predefined distance threshold factor. The first operating position is recorded as a reference point in a system for the vertical movement of the reference wheel.

Abstract: A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position. The measuring position is vertically below a reference wheel. The reference wheel is continuously vertically lowered so that its lower surface comes into contact with the rotary roller and produces a bearing force on the roller. The roller is continuously moved in the direction of lowering. A distance between an index, which is secured to a measuring arm of the frame, and an articulated column of the frame is repeatedly measured during the continuous movement. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position in which the distance is equal to a predefined factor of the distance threshold.

Abstract: A method is provided for adjusting the thickness of the welding bead of two bands obtained by butt welding by means of a laser beam without using filler material. The bands are clamped in jaws, both cut edges being spaced apart by a reference distance. Then the mobile jaw is moved along a travel. Said travel differs from said reference distance by an offset calculated in relation to the thickness of the bands, and while taking into account the degree of accuracy of the positioning and of the cut of said edges. The offset is counted as positive or negative, in order to obtain a final welding position such that it exists, between the edges, an actual allowance, positive or negative, adapted to the thickness of the bands.
