  • Patent number: 8523100
    Abstract: A bobbin holder for tensioning a bobbin tube and receiving a wound thread bobbin is presented. The bobbin holder includes a rotatable drive shaft that is connected to a drive with a bearing end thereof and that has a tensioning device for tensioning a bobbin tube on a tensioning end. The tensioning device includes a plurality of bobbin tubes on the periphery of the drive shaft and interposed tensioning rings. A tensioning piston guided on the free end of the drive shaft acts upon at least one of the bobbin tubes to deform the tensioning rings. In order to allow the use of high fatigue strength materials for the tensioning ring, the tensioning ring includes a continuous separating slot on the periphery, which extends between two opposite ring ends of the tensioning ring, deformation being essentially achieved by an expansion of the tensioning ring.

  • Patent number: 8333388
    Abstract: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

  • Patent number: 7905444
    Abstract: A carbon ribbon shaft is provided for a barcode printer and includes a shaft rod and at least one first rotation member and one second rotation member. The shaft rod has an end coupled to a housing of the barcode printer. The first and second rotation members are fit over the shaft rod. Arranged between inside of the first rotation member and the shaft rod is a resilient element that allows the first rotation member to effect resilient rotation with respect to the shaft rod. The first rotation member has an outer surface forming sliding-resistant resilient tabs. Arranged between inside of the second rotation member and the shaft rod is a resilient element that allows the second rotation member to effect resilient rotation with respect to the shaft rod. The second rotation member has an outer surface forming sliding-resistant resilient tabs. The surfaces of first and second rotation members receive a carbon ribbon roll of the barcode printer to fit thereon.

  • Patent number: 7455261
    Abstract: A tightening mechanism for adjustably setting a tape holder to an immovable state on a tape dispenser includes a tape holder being provided at an axially outer end with a flared round recess, a bushing ring having a bevel wall and being fitted in the flared round recess, and a locating member slightly smaller than the bushing ring for fitly seating in the bushing ring. A turning knob having a spring put thereon is sequentially extended through the locating member and the bushing ring to screw into a fixing bar, on which the tape holder is mounted. When the knob is turned, a tightness of the bushing ring against the flared round recess is progressively changed to thereby adjust the tape holder to different degrees of immobility, allowing the tape dispenser to apply to tapes of different adhesion ability.

  • Patent number: 7322761
    Abstract: A spool, such as supply for a wide-format printer, is provided. The spool comprises a spindle for slidingly receiving an outer shaft, which is typically the core of a roll of print media. A first resiliently deformable gripping ring is circumferentially mounted about the spindle, and a compression mechanism is provided for axially compressing the gripping ring. The axial compression causes radial expansion of the gripping ring, thereby urging the gripping ring into gripping engagement with the outer shaft received on the spindle.

  • Patent number: 6357687
    Abstract: An easily tear-off tissue holder includes a base, a shaft connected with and standing on the base, a fix rod connected with the shaft and having a slide hole for an upper small diameter connect rod of the shaft to fit and move up and down therein, and a press member connected on top of the fix rod to press down the fix rod and an elastic cylindrical member. When the press member is pressed down the fix rod and the elastic cylinder member, the elastic cylinder member with vertical slots and of narrow strips defined by every two neighboring vertical slots may elastically bend diametrically outward to push an inner wall of a cylindrical shaft of a coil tissue to stop the coil tissue immovable for easily tearing off a proper length of the tissue, by which the coil tissue may not be smeared in tearing off action.
