Abstract: A presser assembly is provided in which a presser plate or presser board mounting adapter is clamped to a lower end of a presser stem. 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.

Abstract: A rail assembly is provided for supporting a blanking tool insert on an outer frame for a lower blanking tool of a die cutting machine. The rail assembly includes an elongated insert receiving structure for receiving a portion of the blanking tool insert. A plate member is interconnected to the outer frame and a clamping structure is operatively connected to the plate member. The clamping structure is movable between a clamping position for rigidly retaining a portion of the insert receiving structure against the plate member and a release position.

Abstract: A panel connection device is provided for attaching a panel of an inner grid to an outer frame for a lower blanking tool of a carton die cutting machine. The panel connection device includes a plate member defining inner and outer faces. The plate member has a recess formed therein for receiving a portion of the panel and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face. A clamping structure extends into the recess in the plate member for retaining a portion of the panel therein. A fastening element extends through the bore in the plate member into a corresponding slot in the outer frame to interconnect the plate member to the outer frame.

Abstract: A welding jig is provided for supporting and aligning first and second workpieces in preparation for a welding operation. The welding jig includes a first support arm extending along a first axis. A second support arm is operatively connected to the first support arm and extends along a second axis generally perpendicular to the first axis. A first clamping member is operatively connected to the first end of the first support arm for supporting a first workpiece. A second clamping member is pivotably connected to the first end of the second support arm for supporting a second workpiece. The second clamping member may be pivoted about a vertical axis for adjusting the angle between the first and second workpieces. In addition, the axial position of the second workpiece may be adjusted by moving the second clamping member along an axis parallel to the first workpiece.
