A rail having a lower channel and an upper channel is provided for clamping the presser plate or presser board mounting adapter to the stem, and more particularly, a presser foot coupled to the lower end of the stem. The present invention allows the presser plate or the presser board mounting adapter to be mounted to the stem without the use of tools or fasteners. ## Claims ### Claim 1 A presser assembly for a blank making machine, comprising: a shaft having a terminal end; a foot pivotably coupled to the terminal end of the shaft; a rail having first and second ends and defining an upper channel and a lower channel, the foot being receivable in the upper channel; and a planar member retained in the lower channel of the rail, the planar member having at least one end extending beyond the first end of the rail. ### Claim 2 (depends on 1) The presser assembly of claim 1 wherein the planar member is a metallic presser plate. ### Claim 3 (depends on 1) The presser assembly of claim 1 wherein the rail is configured such that the foot is slidably received by the upper channel. ### Claim 4 (depends on 1) The presser assembly of claim 1 further comprising a presser board coupled to the planar member. ### Claim 5 (depends on 4) The presser assembly of claim 4 wherein the planar member is a mounting plate having at least one opening and wherein the presser board has at least one hole aligned with the at least one opening, and further comprising at least one fastener extending through the least one opening and the least one hole to couple the presser board to the mounting plate. ### Claim 6 (depends on 4) The presser assembly of claim 4 wherein the presser board is made of wood. ### Claim 7 (depends on 1) The presser assembly of claim 1 wherein the planar member is made of one of metal and a metal composite. ### Claim 8 A presser assembly for a blank making machine, comprising: a shaft having a terminal end; a foot operatively coupled to the terminal end of the shaft; a rail defining an upper channel and a lower channel, the foot being receivable in the upper channel; a planar member retained in the lower channel of the rail, the planar member including a mounting plate having at least one opening; a presser board coupled to the planar member, the presser board having at least one hole aligned with the at least one opening, and at least one fastener extending through the least one opening and the least one hole to couple the presser board to the mounting plate. ### Claim 9 A presser assembly for a blank making machine, comprising: a shaft having a terminal end; a foot operatively coupled to the terminal end of the shaft; a rail defining an upper channel and a lower channel, the foot being receivable in the upper channel; and a planar member retained in the lower channel of the rail; wherein the upper channel is wider than the lower channel. ### Claim 10 (depends on 9) The presser assembly of claim 9 wherein the rail has a lower portion defined by a base and first and second upturned members extending from the base, and an upper portion defined by a first wall extending from an exterior surface of the first upturned member and a second wall extending from an exterior surface of the second upturned member, and wherein top surfaces of the upturned walls define a lower bound of the upper channel and provide a seat for the foot. ### Claim 11 (depends on 10) The presser assembly of claim 10 further comprising first and second inturned members extending inwardly from the first and second upturned members, respectively, and wherein bottom surfaces of the first and second inturned members define an upper bound of the upper channel. ### Claim 12 A presser assembly for a blank making machine, comprising: a shaft having a terminal end; a foot pivotably coupled to the terminal end of the shaft; a rail defining an upper channel and a lower channel, the foot being receivable in the upper channel; a planar member retained in the lower channel of the rail; and a presser board coupled to the planar member, the presser board being made of wood.
