Abstract: This implementation method is used for an ultrasound scanner including an ultrasound scanner probe used to explore an area of interest on the human body, in which a drive system including a stepper motor and a carrier supporting a transducer element is controlled in order to pick up echo lines via the transducer element. An imaging algorithm is applied and image points are analyzed along an arc at a given depth for two series of successive emission and return echo lines, in order to determine the angular offset of the image points in the two successive arcs and calculate the angular offset of the emission echo lines and return lines induced by the operation of the drive system, and then offset is corrected.

Abstract: A first ply and then a second ply, which is superposed on the first ply, are produced on a hoop-type first support. The hoop-type first support has a first receiving surface, to form a laminate. The first and second plies forming the laminate are transferred onto an annular second receiving surface of a core so that the laminate is wrapped on the core until each ply is closed on itself and the laminate is thus closed on itself in a ring about the central axis of the core.

Abstract: The device comprises at least one module for stitching the tread and a means for moving the module vertically and horizontally. The stitching module comprises a frame which is provided with a fixed stitching assembly, equipped with spikes, and at least one mobile stitching assembly. The at least one mobile stitching assembly comprises at least one stitching plate provided at the base of same with at least one planar horizontal contact surface, from which at least two spikes protrude. The plate is arranged in a vertical guide space provided in the frame such that the spikes protrude downwards and such that it is free to move vertically in this space over a limited travel path. The device also includes a vertical movement device for moving the plate from the top downwards in this guide space and a device for locking the altitude position of the plate in this space.

Abstract: The cutting system is configured to cut a continuous strip which extends lengthwise in a longitudinal direction and widthwise between a first edge and a second edge into strips. The cutting system includes a drive device which imparts to the continuous strip a feed speed, a first cutting roller and a contrarotating second cutting roller that cooperate to cut the continuous strip across its full width. The first cutting roller is provided with a first helical blade and is driven in rotation A variable synchronizer makes it possible to select and to modify the synchronization ratio between the rotational speed of the first cutting roller and the non-zero forward speed of the continuous strip in such a way as to be able to adjust the cutting angle according to which the cross-section of the continuous strip is oriented with respect to the longitudinal direction of the continuous strip.

Abstract: The method includes the step of running a cutting means between two threads of the reinforcing ply. The method proceeds with the steps of measuring; a discrepancy between an actual cutting line (A?B?C?) and a theoretical cutting line (ABC) is measured and determining a point of intersection of the actual cutting line (B?) with a reference longitudinal line (XX?) placed on the strip. The actual cutting line (B?C?) of that part of the rubber profiled elements that are not superposed with the reinforcing ply is longitudinally offset (Z) with respect to the theoretical cutting line (BC) so that the actual cutting line (B?C?) meets the reference longitudinal line (XX?) at the point of intersection (B?) of the reinforcing ply (A?B?) with the reference longitudinal line (XX?). The rubber profiled elements that are not superposed with the reinforcing ply are cut along the said actual cutting line.
