Abstract:
1. An apparatus for making book cover panels, the apparatus comprising: a transport mechanism constructed and arranged to feed a sheet of rigid book cover stock material to a cutting machine; a vertical cutter constructed and arranged to produce a vertical cut of the sheet of rigid book cover stock material; and a horizontal cutter constructed and arranged to produce a horizontal cut of the sheet of rigid book cover stock material without rotating the material after making a vertical cut, wherein properly dimensioned book cover panels are provided from the sheet of rigid book cover stock material; wherein the horizontal cutter comprises a blade and an anvil, the anvil having a flat surface, the blade configured to compress against the flat surface of the anvil, the horizontal cutter being constructed and arranged to produce a horizontal crush cut of the sheet of rigid book cover stock material; and wherein the horizontal cutter includes a first toggle linkage rotatable about a first pivot point, a second toggle linkage rotatable about a second pivot point, and an actuator coupled to the first toggle linkage and the second toggle linkage, the actuator being configured to rotate the first toggle linkage about the first pivot point and further configured to rotate the second toggle linkage about the second pivot point, the first toggle linkage including a first pair of link arms coupled at one end to the first pivot point and at the other end to the blade of the horizontal cutter, and further including a second pair of link arms coupled at one end to the first pivot point and at the other end to the anvil, the second toggle linkage including a third pair of link arms coupled at one end to the second pivot point and at the other end to the blade of the horizontal cutter, and further including a fourth pair of link arms coupled at one end to the second pivot point and at the other end to the anvil, such that movement of the actuator translates into raising and lowering of the blade with respect to the anvil via the first toggle linkage and the second toggle linkage.
