Abstract: A transfer assembly for positioning between conveyor sections and for transferring at least one article laterally with respect to the conveying surface defined by the conveyor sections in a direction angled to the conveying direction of the conveying surface includes at least two conveying devices, which define a conveying surface for at least generally aligning with the conveying surface of the conveyor sections, and a sheave assembly. The sheave assembly includes a support member and a reinforced transfer belt having a belt length and defining a transfer surface. At least two transfer sheaves are mounted to the support member with the transfer sheaves supporting the transfer belt. The support member is adapted to move the transfer belt between a non-transferring position wherein the transfer surface is below the conveying surface of the conveying devices and a transferring position wherein the transfer surface is raised above the conveying surface of the conveying devices. The transfer assembly is adapted to move the transfer belt such that the length of the transfer belt changes less than one-quarter of an inch when moved between its non-transferring position and its transferring position.

Abstract: A belt assembly for a belt turn conveyor includes a belt with a plurality of longitudinal fibers generally aligned or oriented along the curved longitudinal axis of the belt. The belt may comprise a plurality of belt segments which are interconnected to form an endless belt, with each belt segment preferably including a plurality of longitudinal fibers aligned along the longitudinal axis of each respective belt segment. When interconnected, the longitudinal fibers of each belt segment generally align along the curved longitudinal axis of the belt. Alternately, the belt may be woven such that the longitudinal fibers are substantially aligned along the curved longitudinal axis of the curved belt. Thus, a belt assembly for a belt turn conveyor is provided that exhibits a more uniform stiffness along its length, which results in the belt assembly exhibiting reduced forces across its length thus increasing the belt's capacity and longevity.

Abstract translation: 用于皮带转动传送带的皮带组件包括具有多个纵向纤维的皮带，所述多个纵向纤维通常沿皮带的弯曲纵向轴线对齐或取向。 带可以包括互连以形成环形带的多个带段，每个带段优选地包括沿着每个相应带段的纵向轴线对准的多个纵向纤维。 当互连时，每个带段的纵向纤维通常沿着带的弯曲纵向轴线对齐。 或者，带可以被编织成使得纵向纤维基本上沿弯曲带的弯曲纵向轴线对齐。 因此，提供了一种用于皮带转动传送带的皮带组件，其沿其长度呈现更均匀的刚度，这导致皮带组件在其长度上表现出减小的力，从而增加皮带的容量和使用寿命。
