    摘要： The invention relates to a device (2) for cutting a reinforcing ply (N) consisting of an assembly of wire sections of a given length, which are embedded in a rubber mixture, arranged parallel to one another and which form a given theoretical angle (a) with the longitudinal direction of the ply, characterized in that it includes a first means (23) which, without cutting out said ply (N), is capable of estimating the actual angle of the wires with the longitudinal direction (XX') of the device, and a second means (25) capable of cutting the ply (N) at the actual angle (a+da) estimated by the first means (23).

    摘要： The invention relates to a device for cutting and transferring a strip section (T) from a continuous strip (B), which includes first (T
    1 ) and second (T
    2 ) surfaces and which is to be deposited onto a rotatable receiving surface (6) on which the various components constituting a tire are assembled, including: a cutting means (3) capable of separating said section from the continuous strip along a cutting line (LC); a telescopic conveyor belt (5) arranged in a longitudinal direction (Y'Y) between the cutting means and the receiving surface, and intended for receiving the strip section via the first surface (T
    1 ) thereof; a first half-anvil (1), which is placed upstream from the cutting line (LC) and which comprises a holding means capable of holding the strip via the first surface (T
    1 ) thereof; and a conveyor (4) having a holding means capable of holding the front (T
    f ) or rear (T
    r ) edge of the strip section (T) via the second surface (T
    2 ), said conveyor (4) being movable in the longitudinal direction (Y'Y). Said device includes a second half-anvil (2) which is to cooperate with the first half-anvil (1) during the cutting of the strip, which is arranged downstream from the cutting line (LC) and upstream from the telescopic conveyor belt (5), and which comprises a holding means which is capable of holding the rear edge (T
    r ) of the strip section via said first surface (T
    1 ) and which is movable in the longitudinal direction (Y'Y).

    摘要： The invention relates to a variable-diameter assembly drum for manufacturing a tire blank having a generally cylindrical receiving surface consisting of segments (4) that are radially movable and have elements of which the radially outer portion forms the receiving surface (41, 42, 5, 45, 71), the receiving surface including at least one circular groove (43, 44) containing a resilient circumferential sleeve (5) that is radially spaced apart from the base of the groove by means of push members (1) which are radially movable relative to the movable segments (4), so as to align the radially outer surface of the sleeve (5) with the receiving surface when the drum is set to a first positioning diameter, and which engage with the base of the groove by means of resilient circumferential tension when the drum is set to a positioning diameter greater than said first positioning diameter. Releasable bolts (2) are capable of holding the push members (1) in the position in which the radially outer surface of the sleeve (5) is aligned with the receiving surface, regardless of the diameter to which said receiving surface is set.
