摘要： Apparatus for stacking a web in a cut or zigzag folded condition. A supply conveyor overlies a reciprocating transport conveyor. The transport conveyor passes over a skid onto which cut or stacked web is to be disposed. The velocity of reciprocation of the transport conveyor is timed to the speed of the supply conveyor. The transport conveyor is an endless belt having brakes to alternatively seize its upper or lower run as the conveyor is reciprocated.

摘要： A tire building drum having a plurality of alternating wide and narrow drum segments bearing shells matable to form a cylindrical tire-building surface includes a shaft and concentric hub rotatable relative one another to expand and collapse the drum. In a preferred embodiment, blocks coupled to each respective segment via springs are mounted for bidirectional radial movement in rotationally-fixed relation to the shaft. Links nestable when the drum is collapsed connect the blocks with the hub to drive the blocks radially and function as over-center toggles stabilizing the drum when expanded. Variable-engagement slides associated with the blocks most effectively resist non-radial forces exerted by the links when their relative magnitude is greatest. Dimensional stability and precision of the drum are facilitated by radial and angular stops which are not subject to sliding wear. Pins of different lengths coupling the wide and narrow drum segments to the blocks cooperate with the springs to retract the narrow drum segments first and by a greater distance when collapsing the drum. The springs also cooperate with the radial stops by taking up relative movement between the blocks and drum segments to prevent expansion of the drum at any point during transition to its collapsed condition.

摘要翻译： 轮胎成型鼓具有多个交替的宽且窄的鼓段，轴承壳体以形成圆柱形轮胎建造表面，包括可相对于彼此相对旋转的轴和同心毂，用于使滚筒膨胀和折叠。 在优选实施例中，通过弹簧联接到每个相应部分的块被安装成用于与轴的旋转固定关系的双向径向运动。 当滚筒收缩时，可嵌套的连接可将轮毂与轮毂连接，以便径向驱动车座，并在扩展时用作超中心切换，以稳定滚筒。 与块相关联的可变接合滑块最有效地抵抗当链节相对强度最大时施加的非径向力。 鼓的尺寸稳定性和精度通过不受滑动磨损的径向和角度止挡来促进。 将宽和窄的鼓部分连接到块的不同长度的销与弹簧配合，以在折叠鼓时首先缩回窄的鼓部分并且缩短较长的距离。 弹簧还通过吸收块和鼓段之间的相对运动而与径向止动件配合，以防止在过渡到其折叠状态期间的任何点处的鼓的膨胀。

摘要： Two endless belts are formed of steel mesh. The belts are run side-by-side spiralling into the center of the apparatus, reversed and spirally wound out of the apparatus with the outgoing convolutions interleaved between the incoming convolutions. The belts present an inlet at one side of the apparatus and an outlet at the other side of the apparatus. The web is fed into the inlet and conveyed to the outlet. Two or more spiral sections can be run in tandem.
