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.

First claim

What is claimed is:

1. A spring frame system comprising:
a spool having a material thereon, the spool rotating about a spool axis;
a spring frame in mechanical communication with the material,
wherein the spring frame contacts the material to maintain the material against the spool,
wherein the spring frame has opposing members forming a substantially A-frame shape with the opposing members forming a substantially arcuate shape at a connection therebetween, and
wherein the substantially arcuate shape elastically displaces under an application of force from the material; and
a stabilizer positioned between the opposing members and proximate the substantially arcuate shape, such that the substantially arcuate shape elastically deforms about the stabilizer.

2. The system of claim 1 , further comprising a member coupled to the spring frame, wherein the member contacts the material to maintain the position of the material against the spool.

3. The system of claim 2 , wherein the member is a roller.

4. The system of claim 1 , wherein the material is a wire.

5. The system of claim 1 , further comprising a support, wherein the spool axis and the spring frame are coupled to the support.

6. The system of claim 1 , wherein the spring frame is a unitary piece of sheet metal.

7. The system of claim 1 , further comprising a member and a support, wherein the member couples to a distal end of one of the opposing members and the support couples to a distal end of another of the opposing members, the opposing members having a length substantially equal to one another, the member configured to contact the material to maintain the position of the material against the spool and the support configured to retain the spring frame in position with respect to the spool.

8. A spring frame system comprising:
an A-frame type frame having a first section and a second section with an arcuate section at a connection between the opposing members;
a spool configured to rotate about a spool axis and having a material thereon;
a stabilizer positioned between the opposing members and proximate the arcuate section; and
a member coupled to an exterior face of the first section,
wherein under a force applied to the member by the material on the spool the arcuate section elastically deforms about the stabilizer and the first and second sections advance toward one another.

9. The system of claim 8 , wherein the member is a roller configured to rotate about a roller axis.

10. The system of claim 9 , wherein the spool axis and the roller axis are substantially parallel, and wherein under the force the spool rotates about the spool axis and the roller rotates about the roller axis with the material therebetween.

11. The system of claim 10 , further comprising a support, wherein the spool axis and the second section are coupled to the support.
