    • Tyre building drum with turn-up apparatus for building an unvulcanized tyre with tyre components (1, 2) and two bead cores (3, 4) with high bead filling strips (4'). Said drum has two ring segments (6, 7) spaced from each other in order to support a bead core, drum segments (8, 9, 10, 11, 12) placed on the outside of each ring segment in order to support the tyre components. Said drum further has means to radially expand that part of the tyre components which is situated between the ring segments. Said tyre building drum has on both sides outside the ring segments a first and second set of axially extending, hingeable arms (11, 12, 17, 19) each having an end directed to the ring segment, said end having a roller (13, 14, 16, 18) and means to axially and radially move each set of arms from a first position in which the rollers of a set of arms form a virtually closed ring to a second position in order to press the expanded part of the tyre components which is situated between the ring segments to the part of the tyre components which is situated outside the ring segments. Each roller (16, 18) of an arm (17, 19) of the second set is situated between two adjacent arms (13, 14) of said first set and situated on the side of the rollers of the arms of said first set which side is turned away from the ring segments.
    • 具有用于利用具有高珠填充条(4')的轮胎部件(1,2)和两个胎圈芯(3,4)构建未硫化轮胎的翻转装置的轮胎成型鼓。 所述滚筒具有彼此间隔开的两个环形段(6,7),以便支撑一个胎圈芯,放置在每个环段外侧的鼓段(8,9,10,11,12)以便支撑轮胎 组件。 所述滚筒还具有用于径向扩张位于环段之间的部分轮胎部件的装置。 所述轮胎成型鼓在所述环段外侧的两侧具有第一和第二组轴向延伸的可铰接臂(11,12,17,19),每个臂具有引导到所述环段的端部,所述端部具有辊(13, 14,16,18)以及用于将一组臂从第一位置轴向和径向移动的装置,其中一组臂的辊形成实际上闭合的环到第二位置,以便将轮胎部件的膨胀部分 其位于环段之间的位于环形段外部的轮胎部件的部分。 第二组的臂(17,19)的每个辊(16,18)位于所述第一组的两个相邻臂(13,14)之间,并位于所述第一组的臂的侧面上, 侧面与环形部分转动。
