| Apparatus for applying liquid to a workpiece surface by contact, including at least one freely rotatable roller having a cylindrical outer wall whose surface is arranged to contact workpieces or workstock, including elongated sheet stock, and to be rotatably moved thereby while transferring liquid to the surface of the workstock or workpiece by contact. |
| At times, such liquid lubricants and the like may be applied as a spray or mist, but in other instances it is more advantageous to transfer the liquid by contact with an applicator member which makes contact with the advancing workpieces as they pass a particular location. |
| In most instances, the liquid lubricant or the like is applied to such rollers from the outside, by spraying the roller surface or by disposing a drip tube above it from which liquid may fall by gravity onto the surface of the roller. |
