Abstract
An apparatus for pushing out stacked signatures includes a table on which the signatures are placed in a stack. A push-out element is seated above the table in a lever gear so as to be rotatable on a closed path for being applied to the stack in a push-out movement pushing the stack away from the table.
Claims7
An apparatus for pushing out stacked signatures, comprising:
- a table on which the signatures are placed in a stack, said table being in a horizontal position;
- a lever gear including a pivotably driven member having a pivot axis and a horizontal extending arm, said horizontal extending arm being attached to said pivotably driven member and pivoting around said pivot axis;
- and
- a push-out element including a rod, an upper end of said rod being attached to said horizontally extending arm wherein the push-out element is seated above the table in the lever gear so as to be rotatable on a closed path for applying a push-out movement to the stack thereby pushing the stack away from the table, said closed path having a linear displacement section which is associated with the push-out movement of the stack.

An apparatus for pushing out stacked signatures, comprising:
- a table on which the signatures are placed in a stack, said table being in a horizontal position;
- a lever gear including a pivotably driven member, a horizontal extending arm and a cam track, said horizontal extending arm pivoting about the pivotably driven member;
- and
- a push-out element including a rod, an upper end of said rod being attached to said horizontally extending arm wherein the push-out element is seated above the table in the lever gear so as to be rotatable on a closed path having a linear displacement section for applying a push-out movement to the stack thereby pushing the stack away from the table, and wherein said pivoting horizontal extending arm is guided in the cam track at a distance from the push-out element.
