Inventors: Shawen, Harley J.;
Assignee: NCR Canada Ltd. -- NCR Canada Ltee (Mississauga, CA)
Primary Examiner: Cook; Daryl W.

Attorney, Agent or Firm: Cavender; J. T., Hawk, Jr.; Wilbert, Muckenthaler; George J.
A back-up member is provided wherein a single bracket supports an elongated member at several points therealong, one face of the elongated member serving as a flat surface for a plurality of resilient pads which are positioned to be formed in a curved manner by a spring member which is adjacent slant-edged portions of the bracket and secured at the several points thereof. The spring member thereby presents a pair of surfaces for applying pressure on record media to maintain such media in close proximity to associated read and write heads. |

DETAILED DESCRIPTION What is claimed is: 1.
A method of maintaining a document proximal an operating station comprising the steps of: providing a back-up member having spaced deformable members associated therewith, providing a spring element to fit against said deformable members, providing a bracket member having a plurality of upstanding portions including a central portion with slant-edged surfaces on said portions, and moving the back-up member and the spring element, with the deformable members therebetween, against the slant-edged surfaces of said upstanding portions and securing thereto so as to cause the spring element to bear against the slant-edged surfaces and thereby form the deformable member in curved manner to engage said spring element with the document.
2.
A method of making an assembly for maintaining a document in close proximity to an operating station comprising the steps of: providing a spring element, providing a back-up member with spaced compressible members affixed thereon, providing a bracket member having a plurality of upstanding portions including a central portion with slant-edged surfaces thereon, and moving the back-up member against the spring member and against the upstanding portions, the spring member bearing against the slant-edged surfaces and thereby deforming the compressible members between the back-up member and the spring element so as to form a plurality of curved portions in the spring member for engaging with the document.
3.
A method of making back-up means for a document traveling past a processing station comprising the steps of: providing a bracket member having a plurality of apertured upstanding portions and a central portion with slant-edged surfaces thereon, providing a spring element for spanning said upstanding portions and said central portion, providing a plate member having resilient means affixed thereto and positioned between said bracket member and said spring element, and securing said spring element and said plate member to said bracket member, the spring element bearing against said slant-edged surfaces and said resilient means forming a plurality of curved portions in said spring element for engagement with said document
