A bale wrapping device for a round baler includes a drive roller by which a wrapping material is able to be unrolled from a wrapping material roller. The drive roller is connected to a drive and brake apparatus. The drive and brake apparatus is connected to a brake belt which is able to be tensioned in a variable manner. The bale wrapping device further comprises a tensioning lever apparatus and the brake belt is connected to the tensioning lever apparatus. The pre-tensioning of the brake belt is adjustable by means of the tensioning lever apparatus between at least three different pre-tensionings.

Dual action magnetic brakes and related methods are provided. In one aspect, such a brake includes a housing, a rotatable shaft extending through the housing, and a braking assembly in the housing. The braking assembly includes a coil and a braking member. The coil can generate a magnetic field when energized with electrical current. The braking member, and one or more flexible members attached thereto, can move in response to the presence or absence of the magnetic field to facilitate rotation or non-rotation of the shaft.

The present invention provides a system and method for providing drive shaft braking for an irrigation machine. According to an exemplary preferred embodiment, the present invention includes a system for providing drive shaft braking during the operation of an irrigation machine where the irrigation machine includes a drive system having a drive motor and a drive shaft. According to a preferred embodiment, the system in accordance with the present invention preferably includes a cam attached to the drive shaft, an extension arm having a first securing point, a securing arm having a second securing point and a spring attached between the first securing point and the second securing point. According to a further preferred embodiment, the system of the present invention preferably further includes a follower mechanism secured to the extension arm, which applies continual frictional pressure to the drive shaft in response to the force applied by the spring to the follower through the extension arm. According to a further preferred embodiment, an exemplary system according to the present invention functions to hold the drive shaft in place when rotational force is not actively applied to the drive shaft by the drive motor.

A rotary actuator has a rotatable platform rotatably supported on a base. The rotatable platform has a friction surface. An actuator band is operated by a band clamp so as to be selectively frictionally engageable with the friction surface. A motion actuator is coupled between the base and the actuator band such that change in length of the motion actuator causes corresponding movement of the actuator band. A brake band is operated by a brake band actuator so as to be selectively frictionally engageable with the friction surface, the brake band anchored to the base.
