  • Patent number: 11085542
    Abstract: A labyrinth seal including a stator and a non-contacting rotor, and annular elastomeric seals. The confronting surfaces of the stator and rotor define at least one interface passage, including a radially-outermost annular interface passage between an annular, outermost, radially-extending projection of the stator and an annular rearwardly-extending distal projection of the rotor that overlaps the radially-extending projection of the stator, the radially-outermost annular interface passage tapering outwardly and rearwardly at an acute angle relative to an axial reference line. The annular elastomeric seals are stationary with the stator during dynamic operation of the rotor, and are not contacted by a surface of the rotor during dynamic operation. The interface can also have two radially-disposed exclusion chambers, the outer exclusion chamber being defined in part by a radially-inboard projection of the rotor.

  • Patent number: 10974919
    Abstract: A material aligning device having a plurality of sine waves, wherein the sine waves can be in the form of protrusions repeating along an outer surface of a roller. The material aligning device provides an oscillation to the material sheet moving on it to cancel its vibrations, which allows for faster and improved alignment while printing, web converting, and during other similar processes. The material aligning device also relieves the high amount of tension typically necessary for the printing, converting, and other similar material processing using machines. The reduction in tension also reduces the likelihood of the material sheet being overly stretched or for it to rip.

  • Patent number: 9248971
    Abstract: A conveyor roller has a drum shell and an end lid that has an end lid, an embossed spring band, and a mounting face that is affixed to an axial end of the drum shell. The end lid has a cylindrical geometry that mates with the mounting face, whereby the embossed spring band is compressed by an interference fit between the two mating cylindrical geometries. A polymeric seal is disposed between the inward face of the end lid and the outward face of the drum shell, near the outer circumference of the end lid. Thus, the end lid maintains a spring force against the polymeric seal. The end lid has a ring compression geometry for exerting a compressive force on the polymeric seal as the end lid is retained against the drum shell by the embossed spring band. A cleaning system has a shaft with cleaning conduits, inlet and outlet ports, and an end lid.

  • Publication number: 20150075944
    Abstract: The present invention provides a scroll wheel for transferring a glass substrate, which comprises a rolling body and a surrounding member. The rolling body has an outward-curving peripheral surface, and an outermost circumference on the surface of the rolling body has an groove disposed around. The rolling body rotates on a central axis. The surrounding member is engaged with the groove of the rolling body. The surrounding member is in contact with the glass substrate and is used to support and transfer the glass substrate. The present invention can prevent the glass substrate from being scratched in the transferring process and reduce the damage of the glass substrate. Moreover, the present invention can make the best use of an element of the scroll wheel that is reusable and reduce the cost.
