A flush mounted presser assembly for a die cutting machine. The presser assembly includes a support member having an upper surface which defines a substantially horizontal plane, a presser movable vertically in a plane perpendicular to the horizontal plane of the support member between a first extended position spaced from the support member beneath the horizontal plane and a second retracted position also beneath the horizontal plane of the support member, and a mounting arrangement for mounting the presser to the support member wherein the mounting arrangement is disposed flush with or below the horizontal plane of the support member so that none of its components extend or project above the horizontal plane of the support member. The mounting arrangement comprises a base mounted on the support, a linkage assembly interconnecting the base and presser, and a spring for biasing the linkage assembly and presser toward its first extended position away from the support member.

I claim: 1. A flush-mounted presser assembly for a die cutting machine, comprising: a support member having an upper surface which defines a substantially horizontal plane; a presser movable vertically in a plane perpendicular to said horizontal plane between a first extended position spaced from said support member beneath said horizontal plane and a second retracted position beneath said horizontal plane; and mounting means for mounting said presser to said support member, said mounting means disposed flush with or below said horizontal plane so that said mounting means does not extend above said horizontal plane and including: a base mounted on said support; a linkage assembly interconnecting said base and presser, said linkage assembly including: an arm interconnecting said base and presser and having an upper end mounted to said base that simultaneously pivots and moves horizontally with respect to said support as said presser moves between said extended and retracted positions and a lower end pivotally mounted to said presser; a link interconnecting said base and arm and having an upper end pivotally mounted to said base and a lower end pivotally mounted to said arm; and a slider mounted for horizontal sliding movement on said base, and the upper end of said arm is pivotally mounted to said slider; biasing means for biasing said linkage assembly and presser toward said first extended position. 2. The presser assembly of claim 1, wherein said presser comprises a rail member. 3. The presser assembly of claim 2, wherein said rail member is elongate and extends longitudinally parallel to said horizontal plane. 4. The presser assembly of claim 1, wherein said base includes a longitudinally extending and downwardly opening channel. 5. The presser assembly of claim 4, wherein said biasing means comprises a spring disposed within said channel. 6. The presser assembly of claim 1, wherein the pivotal mounting of the lower end of said link is located at the midpoint between said upper and lower pivotal mountings of said arm. 7. The presser assembly of claim 6, wherein the pivotal mounting of the lower end of said link is located in a plane extending through the upper and lower pivotal mountings of said arm. 8. The presser assembly of claim 6, wherein the distances between the pivotal mounting of the lower end of said link and (a) the pivotal mounting of the upper end of the said link, and (b) the pivotal mounting of the upper end of said arm, and (c) the pivotal mounting of the lower end of said arm, are all equal. 9. The presser assembly of claim 1 wherein said base includes a longitudinally extending downwardly opening channel, and said slider is disposed in said channel. 10. The presser assembly of claim 9, wherein said biasing means comprises a spring disposed within said channel acting against said slider. 11. The presser assembly of claim 1 wherein said mounting means includes a linkage assembly having only a single pivot connection interconnecting said linkage assembly and said presser. 12. The presser assembly of claim 1 wherein said mounting means includes a linkage assembly having two pivot connections interconnecting said linkage assembly and said support member. 13. The presser assembly of claim 3 wherein said rail member extends longitudinally along a straight line. 14. A presser assembly for a die cutting machine, comprising: a housing extending along a first horizontal axis; a presser extending along a second horizontal axis generally parallel to the first axis and being positioned beneath the housing, the presser being movable between a retracted position and an extended position; and linkage for interconnecting the housing and the presser, and for preventing horizontal movement of the presser as the presser moves between the retracted position and the extended position, the linkage including a base operatively connected to the housing, an arm interconnecting the base and presser, and a biasing structure including a spring extending along a third axis parallel to first and second axes for resiliently biasing the linkage arm and presser downwardly toward said extended position. 15. The presser assembly of claim 14, wherein said presser comprises a rail member. 16. The presser assembly of claim 14, wherein the housing includes a channel and wherein the spring is disposed within the channel in the housing. 17. A presser assembly for a die cutting machine, comprising: a housing extending along a first horizontal axis; a presser extending along a second horizontal axis generally parallel to the first axis and being positioned beneath the housing, the presser comprising a rail member and being movable between a retracted position and an extended position; and linkage for interconnecting the housing and the presser, and for preventing horizontal movement of the presser as the presser moves between the retracted position and the extended position, the linkage including a base operatively connected to the housing, an arm interconnecting the base and presser, a biasing structure for resiliently biasing the linkage arm and presser downwardly toward said extended position; and a link interconnecting the base and the arm and having an upper end pivotally mounted to the base and a lower end pivotally mounted to the arm. 18. The presser assembly of claim 17, wherein the pivotal mounting of the lower end of the link is located at the midpoint between the upper and lower pivotal mountings of the arm. 19. A presser assembly for a die cutting machine, comprising: a housing extending along a first horizontal axis, the housing including a longitudinally extending and downwardly opening channel; a presser extending along a second horizontal axis generally parallel to the first axis and being positioned beneath the housing, the presser comprising a rail member and being movable between a retracted position and an extended position; linkage for interconnecting the housing and the presser and for preventing horizontal movement of the presser as the presser moves between the retracted position and the extended position, the linkage having first and second ends and including a base operatively connected to the housing and an arm interconnecting the base and presser, and a spring engaging one of the first and second ends of the linkage for resiliently biasing the linkage arm and presser downwardly toward said extended position. 20. The presser assembly of claim 19 wherein the spring is disposed with the channel in the housing.
