  • Patent number: 11731791
    Abstract: The invention relates to a brake device for producing a brake torque counter to a torque acting on a rotatably supported member, wherein the brake device has: at least one toothed brake ring which is mechanically actively connected to the rotatably supported or supportable member, a plurality of bending-resistant brake levers which each have at a first lever end at least one stop which engages in the tooth arrangement of the brake ring and which are each rotatably supported on a second lever end opposite the first lever end, wherein each brake lever is connected to a force element for applying a brake force in such a manner that, as a result of the brake force via the stop of the respective brake lever which is in engagement with the tooth arrangement of the brake ring, a brake torque is produced on the brake ring tangentially counter to the active direction of the torque in order to apply a brake torque to the rotatably supported or supportable member, wherein the brake levers are arranged with respect to

  • Patent number: 9908654
    Abstract: An apparatus for storing, transporting and dispensing conveyor belts is described. The apparatus, in the form of a crate, has top and bottom conventional pallets, allowing for easy handling and strength for additional stacked crates. The center of the crate holds a hub assembly that moves rotationally, and allows smooth transition from consecutive layers of the conveyor belt wrapped thereon. During shipment, the roll of conveyor belt lies on its side. In one embodiment, a center pipe axle of the spool passes through holes in the top and bottom pallets. Alternatively, the center pipe axle passes through channels created between planks of the top and bottom pallets. These configurations secure the roll in the crate, and allow it to turn freely when loaded or unloaded.

  • Patent number: 8127583
    Abstract: A mandrel for winding sheet metal has a generally tubular mandrel body extending along and centered on an axis and formed at one end with a plurality of radially throughgoing and angularly spaced apertures each having a pair of closed and axially confronting end faces, a spreading bar extending axially inside the body and having a respective pivot adjacent each of the apertures, respective rigid links extending through the apertures and having inner ends carried on the respective pivots and outer ends projecting outside the body, and respective segments outside the body and each pivoted on the outer end of a respective one of the links. Respective pressure plates are operatively connected at the one end between the segments and the mandrel body.

  • Patent number: 7424987
    Abstract: Coiling device (10) and relative coiling method for rolled or drawn long products, comprising a mandrel (11), arranged cantilevered and rotatable with respect to a central longitudinal axis (X), and on which the long products are wound in adjacent and superimposed spirals (33), in order to form a compact coil (31) having the geometric shape of a circular ring with lateral flanks substantially orthogonal, or very angled, with respect to the central longitudinal axis (X). The mandrel (11) comprises a flange (12) substantially orthogonal, or very angled, with respect to the central longitudinal axis (X) which defines a first lateral flank of the coil (31). The mandrel (11) also comprises first arm elements (13) which define the cylindrical surface of the core that forms the coil (31), and second arm elements (14), opposite the flange (12), which define a second flank of the coil. The first and the second arm elements (13,14) are mobile between a first coil-forming position and a second coil-removal position.

  • Patent number: 6345781
    Abstract: A self-adjusting payoff comprising a frame, and a pivoting spool mounted in the frame. The pivoting spool comprises an axle, at least three pivot assemblies slideably mounted on the axle and an adjustment mechanism for adjusting the location of the pivot assemblies relative to the axle. Each of the pivot assemblies comprises a pair of freely rotating, parallel arms extending radially from the axle toward and rotatably attached to coil supports that, when the pivoting spool is adjusted to its most extended position as described hereinafter, extend parallel to the axle. Operation of the adjustment mechanism causes movement of the extremities of the parallel arms proximate the axle to move inward or outward along the axle thereby adjusting the relative distance between the axle and the supports permitting acceptance of variously sized coils by the payoff.
