  • Patent number: 8727259
    Abstract: A self-compensating tension control device for regulating the withdrawal of filamentary material from a spool includes a fixed support that maintains an inverted cam surface and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. A braking mechanism includes a brake drum rotatable with the spindle assembly, a friction band adapted to engage the brake drum and a rocker arm that engages the cam surface. When the tension force applied to the filamentary material is reduced and unable to overcome the biasing force, the cam roller engages the cam surface and causes the friction band to generate a braking force on the brake drum. Withdrawal of the filamentary material at a regular rate occurs when the biasing force is balanced with the tension force.

  • Patent number: 8500056
    Abstract: A self-compensating tension control device for regulating the payout of filamentary material from a spool includes a fixed support and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. An eddy current braking system includes a conductive member rotatable with the spindle assembly and a magnetic member carried by the fixed support. The spindle assembly and the conductive member move linearly toward a side-by-side relationship with the magnetic member when the tension force applied to the filamentary material is reduced and unable to overcome the biasing force. Linear movement of the spindle assembly and the associated conductive member can be obtained by either a straight line mechanism or a linear ball bushing mechanism. A supplemental brake may also be used.

  • Patent number: 7338004
    Abstract: A spool (1) mounted on a rotating shaft (2) with a brake drum (3) attached to it is mounted onto a swing lever (4). The swing lever is hinged on a creel channel (6). A loading-force is pushing the brake drum against a fixed brake shoe (9) which is located at such an angle to the swing lever that the tension in the withdrawn strand (10) is not dependant on the diameter of the spool but is constant.

  • Patent number: 7114674
    Abstract: An idler roll brake in a paper handing machine wherein the roll brake employs a brake shoe mounted to the roll end bearing. The brake shoe slides forward to bring the brake shoe against the interior surface of the roll. An electromagnet positioned external to and mounted closely spaced from the cylindrical shell the roll attracts a ferromagnetic armature or permanent magnet mounted to the brake to pull the brake shoe into engagement with the inner surface of the roll.

  • Patent number: 7017849
    Abstract: An idler roll brake in a paper handing machine employs an electromagnet positioned close to the periphery all of the idler roll which interacts with and induces eddy currents a conducive roll and a gear shaped steel ring fitted within the conducive roll. The electromagnet is arranged transverse to the axis of the roll and has three poles. The gear-shaped steel ring forms opposite poles which are attracted to the poles of the electromagnet which bring the roll to complete stop. An alternative embodiment roll brake employs a brake shoe mounted to the roll end bearing. The brake shoe slides forward to bring the brake shoe against the interior surface of the roll. An electromagnet positioned beneath the roll attracts a ferromagnetic armature or permanent magnet mounted to the brake to pull the brake shoe into engagement with the inner surface of the roll.

  • Patent number: 6290161
    Abstract: A winder comprises a base, a wire wheel, and a braking mechanism. The base has a face plate which is provided with a main shaft and at least one arcuate hole. The wire wheel is rotatably mounted on the main shaft. The braking mechanism comprises a one-way bearing, a shaft sleeve, a brake disk, two friction pads, a clamp seat, and an adjustment knob. The one-way bearing is disposed in the axial hole of the wire wheel. The shaft sleeve is fitted over the main shaft such that a first end thereof is in contact with the inner edge of the bearing, and that a second end thereof is fastened with the brake disk. The friction pads are fastened with the shaft sleeve and located at two sides of the brake disk. The clamp seat is slidably disposed on the shaft sleeve and is fastened with the adjustment knob. The magnitude of frictional force between the brake disk and the friction pads is adjusted by turning the adjustment knob, thereby resulting in a braking effect on the wire wheel in motion.
