Abstract
A press roller spring frame is provided. The spring frame includes a frame body having a first section having an arcuate shape, a second section extending from the first section and having a substantially planar shape, a third section extending from the first section and having a substantially planar shape. The second and third sections are configured to oppose one another with the first section therebetween. The spring frame further includes a roller operatively coupled to the third section and configured to rotate about an axis. A compressive force may be applied to the roller to displace the third section closer to the second section, whereby the arcuate shape of the first member is compressed. The compression causes the first member to produce a spring force that resists the compressive force applied against the roller to keep the roller against the object applying the compressive force.
