  • Patent number: 7147724
    Abstract: A longitudinal cutting device, that is usable for cutting a length of material such as a fabric or a paper web, includes a cylinder which supports the length of fabric or web. A blade cooperates with the cylinder to cut the fabric or web. A blower nozzle is used to direct a flow of fluid against the surface covering the cylinder. A suction nozzle is provided for suctioning the flow of fluid from the covering surface before it touches the length of fabric or the web.

  • Patent number: 4679458
    Abstract: A worm gear has a threaded spindle and a threaded nut, the thread on the spindle or the nut or on both having a profile such that the transition regions connecting the thread crown surface to the thread flanks are rounded, as is the crown surface itself. Further, the spindle thread and nut thread are intermeshed with axial and radial play such that radial forces exerted under torque loading are transmitted only by areas of the crown surface, which transmitted forces are supported by the respective areas of the opposing groove bottom. Smooth functioning is ensured even when the threaded spindle occupies a position of maximum inclination relative to the nut.

  • Patent number: 4621402
    Abstract: The invention pertains to a process and a device for the assembly of universal joints. In order to reduce the defect of center misalignment of the joint parts with respect to each other which characterized the joints after assembly, the center misalignment resulting from different pressing forces on the bearings and from other manufacturing tolerances are measured according to the invention during assembly, whereupon appropriate corrective forces are generated to eliminate the misalignment of the centers.

  • Patent number: 4584749
    Abstract: The invention pertains to a process and a device for the production of pocket cages for roller bearings. The starting material is a cup-shaped blank or a tube, and the lateral surfaces of the cage are cut at the same time that the rolling element pockets are stamped out. In this way a work step on a separate processing machine is eliminated.

  • Patent number: 4558502
    Abstract: A method for the assembly of universal joints with radially pretensioned fork arms, consisting of the steps of inserting and positioning the joint cross in the joint fork, pressing in the bearing and fixing them by means of pressure units, one of which supports each fork arm and pretensioning each fork arm individually during the entire pressing-in and/or fixing phase by means of the tipping force resulting from the pressure prevailing between the support element and the pressing/peening tool, reduced by a partial force following in response to the amount of the pressing force.

  • Patent number: 4435889
    Abstract: A process and apparatus for forming a cage part, for a ball bearing, wherein the cage parts are annular with alternate flat portions and ball receiving recesses. The cage parts are formed by pressing the rings from cage material such as steel. The flat portions are formed with axially extending rivet pins or holes for receiving the rivet pins of another cage part, in order to enable fastening of the cage parts together. The rivet pins are formed by pressing operation at the time as forming the cage part, by the flowing of the material of the cage part into recesses in a die.

  • Patent number: 4383670
    Abstract: In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.
