  • Method for singulating a disk
    Patent number: 6113345
    Abstract: An apparatus for discharging disks from the bottom of a stack of aligned disks one at a time is provided. The apparatus includes a pair of feed gate subassemblies supported in a spaced apart, diametrically opposing relationship so as to define a disk receiving opening therebetween. The feed gate subassemblies are adapted to cooperatively support the stack of disks in the disk receiving opening and sequentially engage opposing portions of the outer peripheral edge of the disk positioned at the bottom of the stack of disks so as to cause the bottom disk to be discharged from the stack of disks.

  • Disk singulating apparatus
    Patent number: 5975839
    Abstract: An apparatus for discharging disks from the bottom of a stack of aligned disks one at a time is provided. The apparatus includes a pair of feed gate subassemblies supported in a spaced apart, diametrically opposing relationship so as to define a disk receiving opening therebetween. The feed gate subassemblies are adapted to cooperatively support the stack of disks in the disk receiving opening and abuttingly engage at least a portion of the outer peripheral edge of the disk positioned at the bottom of the stack of disks so as to compress the bottom disk and thus cause the bottom disk to be discharged from the stack of disks.
