Abstract: A system includes a trailer frame, a lifting mechanism coupled to the trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe, a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, and a hydraulic power unit configured to hydraulically power the system.

Abstract: A medium supplying apparatus for applying a back tension opposite to a transferring direction of a rolled medium being transferred by a transfer unit, to the rolled medium, includes a driving unit including a drive gear to be rotated in a forward direction and a reverse direction; a rotation transmitting mechanism that includes a one-way clutch and a torque limiter and transmits a rotational force between the driving unit and a medium rotation shaft that rotatably holds the rolled medium via the one-way clutch and the torque limiter; and a control unit that controls the driving unit to be one of states including being rotated in the forward direction, being rotated in the reverse direction and not being power supplied while the rolled medium is being transferred by the transfer unit to change the strength of the back tension.

Abstract: The present invention relates to a device for winding a plurality of cargo straps thereon where the cargo straps can be removed without disturbing other mounted cargo straps due to a free-wheeling winding cylinder mount on the axle for each cargo strap to be mounted on the axle.

Abstract: A roll-sheet feeding device having a roll sheet wound in a roll to feed a portion of the roll sheet to an image forming unit, includes a progressive mechanism to transmit a drive force from a drive source to transfer the portion of the roll sheet from the roll in a progressive direction, a roll-sheet drive mechanism to receive the drive force transmitted via the portion of the roll sheet transferred in the progressive direction, a rewinding mechanism to transfer the portion of the roll sheet in a direction opposite to the progressive direction via the roll-sheet drive mechanism to rewind the roll sheet, and a regenerating mechanism to obtain the drive force from the roll-sheet drive mechanism and transmit the obtained drive force to the progressive mechanism to regenerate the transmitted drive force as another drive force in addition to the drive force from the drive source.

Abstract: The device comprises: supports (3A, 5A; 3B, 5B) to support at least a reel (B1) in an unwinding position; at least a peripheral drive mechanism which acts on the cylindrical surface of the reel being unwound and transmits peripherally to said reel a torque to draw it in rotation; and at least a center drive mechanism (41) which transmits centrally to said reel an auxiliary torque to draw it in rotation together with the torque transmitted by the peripheral drive mechanism.

Abstract: A dispenser having a start-assist for starting rotation of a coil for dispensing flexible material from the coil includes a frame, a support, a shaft mounted to the support for supporting the coil and configured for rotation with the coil and an arm mounted about the shaft by a one-way element. The arm is connected to the shaft for rotation such that when the arm rotates in a first direction the one-way element engages the shaft to rotate the shaft and when the arm rotates in a second, opposite direction the one-way element is disengaged from the shaft to permit the shaft to freely rotate. When the flexible material is pulled from the coil the arm is rotated in the first direction to begin rotation of the coil by tension in the flexible material.

Abstract: A concentric tape applicator has a support shaft that defines an axis and includes a structure for supporting a tape pad for rotation with the support shaft about the axis. Guide rollers are mounted on the support shaft for rotation concentrically about the axis for guiding tape from the tape pad for application to an elongated member advancing along the axis relative to the support shaft. A drive is directly coupled to the guide elements. A differential clutch is provided that has an input shaft directly coupled to the drive and an output shaft coupled to the support shaft for applying braking forces to the pad. A feedback circuit is provided for sensing the speed of rotation of the pad and applying a feedback signal to the clutch for regulating the excitation of the clutch to maintain a substantial uniform tension on the tape dispensed from the pad so potentially independently of the amount of tape remaining on the pad.
