Abstract

In some examples, an apparatus to apply a coating to a media includes a first roller to receive a continuous belt that is to receive a coating from a second roller and to transfer the coating to the media, the first roller having a variable dimension to provide an adjustable width of the continuous belt to the second roller.

First claim

The invention claimed is:

1. An apparatus to apply a coating to a media, comprising:
a first roller to receive a continuous belt that is to receive the coating from a second roller and to transfer the coating to the media, the first roller having a variable dimension to provide an adjustable width of the continuous belt to the second roller;
a member to move the continuous belt away from the second roller to prevent the coating being applied to the continuous belt by the second roller; and
a controller to determine a length of the media and to control the member to move the continuous belt away from the second roller to provide a length of the coating on the continuous belt corresponding to the determined length of the media.

2. The apparatus of claim 1 , wherein the first roller is adjustable in diameter along at least a portion of the first roller to provide the adjustable width of the continuous belt to the second roller.

3. The apparatus of claim 1 , wherein the first roller is adjustable in width to provide the adjustable width of the continuous belt to the second roller.

4. The apparatus of claim 1 , wherein the first roller comprises an actuator, and the apparatus further comprises a controller to control the actuator of the first roller to adjust the dimension of the first roller.

5. The apparatus of claim 4 , wherein the first roller comprises a plurality of cover members defining an outer surface of the first roller, the plurality of cover members being moveable in a radial direction between an extended position and a collapsed position, and wherein the actuator is to move the cover members between the extended position and the collapsed position.

6. The apparatus of claim 5 , wherein the actuator comprises a rotatable member that when rotated causes the plurality of cover members of the first roller to move.

7. The apparatus of claim 6 , wherein the actuator further comprises a slider to slide along an axis in response to rotation of the rotatable member, the slider comprising a contact portion to push the plurality of cover members as the slider slides along the axis.

8. The apparatus of claim 1 , wherein the coating comprises a primer.

9. The apparatus of claim 1 , comprising a printing system that includes the first roller and the second roller.

10. The apparatus of claim 1 , wherein the width of the continuous belt provided to the second roller is adjustable to correspond to a width of the media.

11. The apparatus of claim 1 , wherein the member comprises a blade.
