  • Publication number: 20190195321
    Abstract: A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed.

  • Patent number: 4883553
    Abstract: A method for forming pads of pressure sensitive adhesive coated sheets with similar discontinuities (e.g., printed indicia or openings) on the sheets substantially aligned. A strip of pressure sensitive adhesive coated material is helically wound around the periphery of a roller to form a roll comprising a multiplicity of overlying layers of the strip by rotating the roller about its axis to pull the strip along a predetermined path onto the roller. Discontinuities are formed on the strip along the predetermined path at locations that are progressively increasingly spaced apart to compensate for the increasing circumference of the roll and which result in at least one set of discontinuities being located along the periphery of the roller in substantial alignment radially outwardly of the roller; and pads containing such aligned discontinuities are then cut from the roll.

  • Patent number: 4825763
    Abstract: Directly printable tape comprising a polymeric film backing having a low adhesion backsize coating on one major surface thereof and a pressure-sensitive adhesive on the other major surface thereof. The low adhesion backsize coating comprises a mixture of a low adhesion backsize compound and an ink adhesion promoter. Also, a method of printing on the low adhesion backsize coating and an ink composition. The ink comprises a conventional flexographic ink composition containing an ink adhesion promoter. The tape is heated to a temperature sufficiently high to soften the backsize coating but not so high as to distort the polymeric backing or degrade the adhesive, with the ink being applied while the backsize coating is in a softened state.

  • Patent number: 4684552
    Abstract: A prefabricated bow form for a Pom bow comprising two opposed bow ribbons with tie ribbons therebetween, with first ends of the bow and tie ribbons bonded together, and with the bow ribbons bonded together at spaced bonded areas to define fold lines about which the bow ribbons will fold when a bow is formed by gathering the bonded areas adjacent the first ends of the ribbon. The fold lines include adjacent fold lines at right angles to the longitudinal edges of the bow ribbons that define therebetween generally central loop forming portions on the bow ribbons, and spaced angled fold lines between the central portions and both ends of the bow ribbons forming additional loop forming portions adjacent both ends of the bow ribbons.
