摘要： A method and apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operation. Two, respectively radially segmented, bead-forming rings that have a variable diameter and can be displaced axially are provided. For the purpose of vulcanizing the sealing surfaces disposed in the interior of the tire so that these surfaces will rest on the rim in an airtight manner, the bead-forming rings are introduced, in a radially retracted state, into the interior of the tire blank, whereby at least one of the tire beads is ovally deformed. The segments of the molding rings are subsequenty extended to an annular radial diameter whereby the molding surface portions of the molding rings can be moved axially outwardly over the tire beads without deforming the latter. The molding rings are then moved axially outwardly over the tire beads and then retracted to their smallest diameter, and are locked into position, whereupon the tire blank is vulcanized in a mold.

摘要： A bladderless tire mold press for tires including lower and upper platens and a mechanism for moving the platens relatively toward one another from an open position to a closed molding position. Each of the platens includes side wall molds for molding the tire sidewalls and thread molds for molding the tire thread. Each of the platens further includes a mechanism for molding tire beads. The tire bead molding mechanism including central mechanisms which are movable relative to their respective platens for insertion into the center of the tire.

摘要： A tire curing press and method are characterized by a center mechanism operative first to center the top bead of a green tire carcass with respect to the top mold section and then the bottom bead with respect to the bottom mold section, and to hold the beads centered and axially separated as the press closes to cause the beads to register and seat with the toe rings of the top and bottom mold sections simultaneously as the press closely approaches its closed condition. The center mechanism comprises top and bottom segmented annular clamping rings adapted to engage and shape the axial interior of the bead area of the tire and respective chuck assemblies including a multi-faceted linear cam and respective followers for each ring segment operative to collapse each alternate ring segment and then each other ring segment. The clamping rings achieve automatic loading, centering and unloading and may be used individually or paired in bladder or bladderless curing.
摘要翻译： 轮胎硫化机和方法的特征在于，中心机构首先使生轮胎胎体的顶部胎圈相对于顶部模具部分中心，然后使底部胎圈相对于底部模具部分居中，并将胎圈保持在中心 并且当压力机关闭时轴向分离，使得当压力机紧密接近其关闭状态时，珠子同时与顶部和底部模具部分的脚趾环对准和对准。 中心机构包括顶部和底部分段的环形夹紧环，其适于接合和成形轮胎的胎圈区域的轴向内部，并且相应的卡盘组件包括多面的直线凸轮以及用于每个环段的各自的跟随器，其可操作地折叠每个替代环 段然后彼此环段。 夹紧环实现自动装载，定心和卸载，可以单独使用或在膀胱或无骨固化中配对使用。

摘要： Along a building line, a green tyre is built on a rigid toroidal support having an outer surface substantially conforming in shape to an inner surface of the green tyre. The green tyre is then transferred to a bead moulding and prevulcanisation station where each bead of the tyre is moulded by tightening it between a surface portion of the toroidal support and an annular clamping surface carried by a removable tightening flange. The tightened beads are prevulcanised through a heat supply by means of electric resistors integrated into the tightening flanges. The tyre with the prevulcanised and tightened beads is transferred into a moulding cavity having an inner wall of a shape substantially conforming to that of the outer surface of the moulded tyre, to carry out moulding of the tyre and complete vulcanisation of same.
