  • Patent number: 6575570
    Abstract: In a framework for eyeglasses the support legs (3) are in engagement with the lens-holding structure (2) through hinge pins (9) mounted rigid with the lens-holding structure (2) or, alternatively, with the legs themselves, and adapted to be coupled with articulation seatings (10). Each articulation seating (10) is defined by a first engagement portion (10a) formed in the respective leg (3) or, alternatively, in the lens-holding structure (2), and a second engagement portion (10b) formed in a covering element (11) to be rigidly engaged in a recess (12) defined in the frames (1).

  • Patent number: 5791570
    Abstract: A mincing unit for an industrial mincing machine having a stator, a rotor and a worm screw drivingly connected to the rotor and positioned within the stator. A set of disc-shaped dies are formed of progressively closer perforations. A set of star-shaped cutters alternate with the dies such that the cutters act on the dies at either end. The cutters are fitted with rectangular blades having a cutting edge surfaced with a wear-resistant material fixed externally to the blades. An element of wear resistant material is mounted on each spoke of the cutters. A freely rotating plate is mounted in an axial area of the cutters.

  • Patent number: 4129979
    Abstract: A yarn-twisting apparatus comprises a spindle receiving the supply spool or bobbin, a rotating can or sleeve surrounding the spool and the bobbin, a yarn takeup arrangement for drawing the yarn from the upper end of the can, and a housing surrounding the can. According to the invention, the stationary housing and the upper and lower ends of the spindle are provided with closures which reach close to the spindle at the bottom and form an opening traversed by the yarn at the top. Means is provided for enabling the upper closure to be removed or displaced for ready access to the interior of the housing. The system reduces the power consumption required for twisting the yarn.

  • Patent number: 4067507
    Abstract: A take-up spool for winding a filament under tension, e.g. preparatorily to its passage through a heating tunnel or other treatment zone, has a core bounded by a pair of cheeks which bracket two parallel rollers freely supporting the core through the filament body being wound thereon. At least one of the rollers is driven to rotate the spool; the other roller may be transversely movable to increase the gap between the rollers for letting the loaded spool drop onto a conveyor or into a receptacle.

  • Patent number: 3962857
    Abstract: A horizontally elongated machine for twisting a plurality of different yarns has at least one longitudinally extending drive shaft. A plurality of horizontally extending and vertically spaced rows of twisters is provided on each side of the machine with each twister being rotatable about a respective axis perpendicular to the longitudinal direction of the machine. The twisters are driven in groups of two or four by a common flat belt spanned over the respective whorls of the twisters and over a single drive pulley on the drive shaft. A takeup device for each of the twisters is provided directly above the twister.
