Abstract:
1. A clamp device for attaching bars of an inner grid to an outer frame for a lower blanking tool of a carton die cutting machine, comprising: an upright plate member defining a substantially flat vertically extending inner face, a substantially flat opposite vertically extending outer face, and a horizontally extending upper face, said plate member further includes a horizontally extending lower face and a substantially U-shaped lower cavity formed in said inner face and opening at its inner end to said inner face and at its lower end to said lower face, said lower cavity defining a lower abutment surface parallel with said upper abutment surface, an opposite upwardly sloped surface disposed at an acute angle with respect to said lower abutment surface, a lower support surface disposed substantially parallel to said upper support surface, and a rear surface extending vertically in a plane parallel to the inner and outer faces of said upright plate member; a substantially U-shaped upper cavity formed in the inner face of said plate member and opening at its inner end to said inner face and at its upper end to said upper face, said upper cavity defining a vertically extending upper abutment surface, an opposite downwardly sloped surface disposed at an acute angle with respect to said upper abutment surface an upper support surface, and a rear surface extending vertically in a plane parallel to the inner and outer faces of said upright plate member; an upper wedge member disposed within said upper cavity for sliding movement along said downwardly sloped surface between clamped and released positions, said upper wedge member being substantially U-shaped and defining a clamping surface disposed parallel to and spaced from said upper abutment surface, an opposite downwardly sloped surface, and a base surface spaced from said upper support surface in said clamped position; and screw means for moving said upper wedge between said clamped and released positions.
