Abstract: A hydraulic hitch system for a vehicle includes a hydraulic source, a hydraulic reservoir, a hydraulic cylinder, an operator-controlled actuating means for generating a command signal, a hydraulic control valve for controlling the hydraulic cylinder, and an electronic control unit for controlling the control valve. To make it easier for the operator to set the hydraulic functions when working with different attachments, a pressure sensor generates a pressure signal and is connected to the hydraulic cylinder, and a control device is used to select a pressure control program for the hydraulic cylinder. The control valve is activated by a control signal which is generated by the control unit as a function of the selected pressure control program, the pressure signal and a command signal generated by the control device.

Abstract: The invention relates to a PTO brake control system. There is a need for an improved and safe PTO brake control system. A PTO may be put into a driven and a non-driven condition an is braked by a PTO brake. A PTO brake control system includes a vehicle speed sensor and an ECU for controlling the PTO brake. The ECU deactivates the PTO brake when the vehicle is stationary and the PTO is not driven. This allows the PTO to be manually rotated to facilitate coupling of the PTO to an implement.

Abstract: A drive arrangement for an agricultural machine with an internal combustion engine used to drive removable agricultural implements. The engine is connected to a control unit and to a power take-off (PTO), which drives the removable agricultural implements, by means of a power take-off transmission with selectable transmission steps. The engine is further coupled to a sensor that captures the RPM of the PTO outlet, to a first operator input device that influences the RPM of the combustion engine and to a second operator input device that inputs a maximum RPM of the PTO output. The control unit controls the RPM of the combustion engine to the input value of the first operator input device while limiting the RPM of the engine based on the RPM at the PTO outlet, which cannot exceed the input value of the second operator input device.

Abstract: Shaft seal for sealing between a shaft (2) and a machine housing (3). A seal and bearing casing (10) surrounds the shaft (2) to be sealed off and contains a rolling-contact bearing device (11) and a row of lip seals (13), the sealing lips of which engage the shaft surface (2) or a shaft protection sleeve (12). A compensation device (14) is connected, an the one hand, in a sealing manner to the casing (10) by means of a radially inner annular fastening part (23), and is connected, an the other band, in a sealing manner to the housing (3) by means of a radially outer annular fastening part (25), and has a flexible bridging portion (24) between the annular fastening parts (23, 25). The bridging portion (24) contains a first and a second elastomer ring seal (24a, 24b), which are arranged at an axial distance from one another in respective seat recesses (26, 27, 28) of the casing (10) and of the compensation device (14).

Abstract: A yarn winding machine for winding a continuously advancing yarn into packages, the yarn being guided in a yarn traversing mechanism which includes a traversing unit and a grooved roll downstream thereof in the direction of the advance of the yarn. To transfer the yarn from a full package mounted on one winding spindle to an empty tube mounted on another winding spindle, the spindle mounting the full yarn package is moved to a doffing position and the spindle mounting the empty winding tube is moved to the winding position. The machine is provided with a yarn deflection device, which comprises a guide plate extending parallel to the circumference of the grooved roll, and a yarn guide adapted for movement in a direction parallel to the winding spindles.

Abstract: A yarn winding machine for winding an advancing yarn to form a yarn package which is formed on a driven winding spindle that is mounted in a projecting manner on a rotatable revolver. The package is engaged on its circumference by a pressure roll which exerts an abutment force on its surface. The winding spindle is supported on a mobile carrier which is mounted on the revolver. During the build of the package, the axial spacing between the package and the pressure roll is changed as a result of an evasive movement, it being possible for the evasive movement to be accomplished in several stages by the movement of the carrier while the revolver is fixed, or by the rotation of the revolver while the carrier is fixed, and so that the abutment force exerted by the pressure roll can be changed.

Abstract: A winding apparatus is disclosed which includes a rotatable revolver having at least one spindle mounted thereon, with the spindle being adapted to coaxially mount one or more bobbin tubes. The revolver is rotatably mounted to the frame of the apparatus by a circular bearing surface of substantial diameter, which provides a very stable and durable mounting. The apparatus also includes a traversing mechanism for traversing an advancing yarn and so as to form a cross wound package on the tubes at the winding position. Also, a contact roll is mounted between the traversing mechanism and the winding position so as to be adapted to rest upon the surface of the package being formed. The contact roll is movable a limited distance radially away from the package being wound, and its position is sensed.

Upon rotation of the revolver, the spindles are moved between a winding position and a doffing position, and a traversing mechanism is provided for traversing an advancing yarn and so as to form a cross wound package on the tubes at the winding position. Also, a contact roll is mounted between the traversing mechanism and the winding position so as to be adapted to rest upon the surface of the package being formed. The contact roll is movable a limited distance radially away from the package being wound, and its position is sensed.

Abstract: An apparatus and method is disclosed for continuously winding a high speed running yarn onto bobbins which are serially delivered to a winding position, and wherein the rotating full bobbins are laterally moved from the winding position to a doffing position. An automatic yarn change-over mechanism is provided for transferring the running yarn from the full bobbin onto an empty bobbin which is brought to the winding position, and as part of the change-over procedure, the yarn is severed so that a free end remains on the rotating full bobbin. In order to prevent this severed yarn end from contacting and becoming entangled in the closely adjacent empty bobbin then being wound at the winding position, there is provided a plate which is pivoted into contact with the rotating full bobbin along a contact line which is located at or immediately upstream of the most narrow gap between the surface of the rotating full bobbin and that of the empty bobbin.

Abstract: A yarn traversing apparatus is disclosed, which is adapted for use in winding a running yarn to form a cross wound package. The traversing apparatus includes a yarn guide bar, and a pair of oppositely rotating rotors, and the rotors include radiating arms which define two closely adjacent planes of rotation. The rotors are mounted for rotation about offset axes, so that the arms sweep across the guide bar in opposite directions to define the yarn traverse stroke. The rotors are rotatably driven by a gear drive system which includes a transmission shaft, and the transmission shaft and one of the rotors are mounted in eccentric bushings which permit the meshing gears to be adjusted so as to eliminate backlash.

The conveyor is located below and in generally the same vertical plane with the spool holder, and the gripper, which is arranged for both rotation and axial translation, is mounted for movement along a three-legged spool doffing and spool-donning path extending forwardly of the machine front. Two embodiments are shown. In the first, a separate empty-spool magazine is provided and the conveyor merely serves to carry away the empty spools.
