Abstract
Abstract Very effective and long-lived printing roller has relatively smooth roll surface of long preferably durable fibers with a denier preferably less than 3, bonded together by yieldable binder, at least the outer portion of the surface being porous. Fibrous surface can be provided by helically wrapping a relatively narrow sheet of felted fibers around roll core and cementing it in place under pressure with helical edges carefully butted together. Alternatively a sheet sufficiently wide can be circularly wrapped several times around the core, cemented in place and then ground to a uniform cylindrical surface, or felted tube can be shrunk on. Raising of a little nap on the surface is helpful. Roller removes hickeys when used in inking train and is also good for dampening in dampening train.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A printing press inking system including a printing-platecontacting roller having a roll surface of a preconstituted dense felt of flexible fibers at least one-half inch long with a denier less than about 3, bonded together by a soft yieldable binder, the felt being at least 15 mils thick and the fibers projecting as a velvety nap from the bonded-together surface.
Claim 2
Dependent Claim
60 words
A printing press inking system including a printing-platecontacting roller having a roll surface of a preconstituted dense felt of flexible fibers at least one-half inch long with a denier less than about 3, bonded together by a soft yieldable binder, the felt being at least 15 mils thick and the fibers projecting as a velvety nap from the bonded-together surface.
Claim 3
Dependent Claim
65 words
A printing press roller having a roll surface of a preconstituted dense felt of flexible fibers which are at least one-half inch long with a denier less than about 5 and are bonded together by a soft yieldable binder, the felt being at least 15 mils thick with its pores substantially completely filled and the fibers projecting as a velvety nap from the filled surface.
Claim 4
Dependent Claim
65 words
A printing press roller having a roll surface of a preconstituted dense felt of flexible fibers which are at least one-half inch long with a denier less than about 5 and are bonded together by a soft yieldable binder, the felt being at least 15 mils thick with its pores substantially completely filled and the fibers projecting as a velvety nap from the filled surface.
Claim 5
Dependent Claim
17 words
The combination of claim 2 in which the fibers are crinkled polyester, polyamide, polyimide or polyacrylonitrile fibers.
Claim 6
Dependent Claim
25 words
The combination of claim 2 in which the binder is an elastomer having by itself a hardness no greater than about 25 durometer Shore A.
Claim 7
Dependent Claim
15 words
The combination of claim 2 in which the binder is a polyurethane or polyurea elastomer.
Claim 8
Dependent Claim
29 words
The combination of claim 2 in which the pores are filled with a material less abrasion-resistant than the fibers and the nap is at least about 3 mils high.
Claim 9
Dependent Claim
28 words
The combination of claim 2 in which the fibers have a denier less than about 3 and the pores of the felt are partially filled with polytetrafluoroethylene particles.
Claim 10
Dependent Claim
32 words
The combination of claim 2 in which the felt is about 40 to 80 mils thick and is held on a rubber layer having a 20 to 50 durometer Shore A hardness.
Claim 11
Dependent Claim
25 words
The combination of claim 8 in which the rubber layer is bonded to a roll shaft and the felt is bonded to the rubber layer.
Claim 12
Dependent Claim
25 words
A printing press plate dampening system having a set of dampening rollers in which set one of the rollers is the roller of claim 2.
