Abstract
In many continuously webbed machines, media is fed through the machine with rollers mounted to one or more rotating shafts. These shafts may be supported on each end with a cylindrical journal bearing. The rollers move at the same rate as the media to maintain traction with the media to control media position as it moves the media from one process to another through the sequence of processes in the webbed machine.
Claims15
An apparatus, comprising:
- a first idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the first idler rotatably mounted to a frame by a first speed-tolerant bearing at the distal end, the first idler having a hollow core at the proximal end and extending a portion of a length of the first idler;
- a second idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the second idler rotatably mounted to the frame by a second speed-tolerant bearing at the distal end, the second idler having a hollow core at the proximal end and extending a portion of a length of the second idler;
- and
- a shaft rotatably mounted to an inner surface of the hollow core of the first idler by a first plurality of heat-tolerant bearings and to an inner surface of the hollow core of the second idler by a second plurality of heat-tolerant bearings.

An apparatus, comprising:
- a first idler having a proximal end with a shaft extending therefrom, and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, wherein the first idler is rotatably mounted to a frame of the apparatus by a first speed-tolerant bearing at the distal end;
- and
- a second idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, and wherein the second idler is rotatably mounted to the frame of the apparatus by a second speed-tolerant bearing at the distal end, the second idler having a hollow core at the proximal end and extending a portion of a length of the second idler;
- wherein the shaft is rotatably mounted to an inner surface of the hollow core of the second idler by a plurality of heat-tolerant bearings.
1 more element
A system, comprising:
- a chassis;
- a media feed including a media path and a plurality of dryers;
- and
- a plurality of co-axial asynchronous idlers mounted on the chassis and disposed between the plurality of dryers, wherein each of the plurality of co-axial asynchronous idlers, includes:
- a first idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the first idler rotatably mounted to the chassis by a first speed-tolerant bearing at the distal end, the first idler having a hollow core at the proximal end and extending a length of the first idler;
- a second idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the second idler rotatably mounted to the chassis by a second speed-tolerant bearing at the distal end, the second idler having a hollow core at the proximal end and extending a length of the second idler;
- and
- a shaft rotatably mounted to an inner surface of the hollow core of the first idler by a first plurality of heat-tolerant bearings and to an inner surface of the hollow core of the second idler by a second plurality of heat-tolerant bearings.
