Device for crosswise laying of rectangular bundles of paper, or the like

Claim 1

A method for crosswise stacking of rectangular bundles of paper or the like comprising conveying uniformly the bundles in a horizontal plane and then permitting the bundles to freely slide on a downwardly inclined plane at an angle to the horizontal plane along a substantially straight path, interrupting said path of movement of every other bundle at a point displaced from the path of movement of the center of the gravity of the bundles, gathering all of the bundles in a stack by letting them freely slide over the downstream edge of said inclined plane and drop down onto each other, the first bundle being received on a second plane sloping downwardly partly in the direction of said conveying path and partly in a direction transverse to the last mentioned direction, and arresting the movement of the bundles in said directions, the distance between said point and said path of movement of the center of gravity being chosen to provide a generally 90° rotation of said every other bundle during its unobstructed movement between said interruption and the engagement with said stack.

Claim 2

A method for crosswise stacking of rectangular bundles of paper or the like comprising conveying uniformly the bundles in a horizontal plane and then permitting the bundles to freely slide on a downwardly inclined plane at an angle to the horizontal plane along a substantially straight path, interrupting said path of movement of every other bundle at a point displaced from the path of movement of the center of the gravity of the bundles, gathering all of the bundles in a stack by letting them freely slide over the downstream edge of said inclined plane and drop down onto each other, the first bundle being received on a second plane sloping downwardly partly in the direction of said conveying path and partly in a direction transverse to the last mentioned direction, and arresting the movement of the bundles in said directions, the distance between said point and said path of movement of the center of gravity being chosen to provide a generally 90° rotation of said every other bundle during its unobstructed movement between said interruption and the engagement with said stack.

Claim 4

A device for crosswise stacking of rectangular bundles of paper or the like comprising means for uniformly conveying the bundles along a substantially horizontal path, an inclined table having one upstream end in the vicinity of the ending downstream point of said horizontal path and inclined downwardly from and forming an angle with said means for conveying, an opening formed in said table in an area distant from the path of travel of the center of gravity of the bundles as the bundles freely slide along said inclined table from said means for conveying in a straight continuation of said conveying path, means for interrupting the path of travel of the bundles, reciprocation in said opening, means for reciprocating said means for interrupting the bundles through said opening so that every other bundles is interrupted, means controlled by the movement of the bundles along said horizontal path for activating said means for reciprocating, a gathering hopper below said inclined table, comprising a face plate having a front upstream edge in the vicinity of the downstream end of said table, said hopper being inclined downward and forming an angle with a horizontal plane partly in the direction of said collecting path and partly in a direction transverse to last mentioned direction, said hopper further comprising two abutments, one abutment formed on each of the two lowermost edges of said front plate, said abutments being arranged perpendicular to each other, the distance between said interrupting means and said path of travel of the center of gravity of the bundles being arranged such as to cause said every other bundle to unobstructedly rotate substantially 90° during its movement between said interrupting means and said hopper.

Claim 5

A device for crosswise stacking of rectangular bundles of paper or the like comprising means for uniformly conveying the bundles along a substantially horizontal path, an inclined table having one upstream end in the vicinity of the ending downstream point of said horizontal path and inclined downwardly from and forming an angle with said means for conveying, an opening formed in said table in an area distant from the path of travel of the center of gravity of the bundles as the bundles freely slide along said inclined table from said means for conveying in a straight continuation of said conveying path, means for interrupting the path of travel of the bundles, reciprocation in said opening, means for reciprocating said means for interrupting the bundles through said opening so that every other bundles is interrupted, means controlled by the movement of the bundles along said horizontal path for activating said means for reciprocating, a gathering hopper below said inclined table, comprising a face plate having a front upstream edge in the vicinity of the downstream end of said table, said hopper being inclined downward and forming an angle with a horizontal plane partly in the direction of said collecting path and partly in a direction transverse to last mentioned direction, said hopper further comprising two abutments, one abutment formed on each of the two lowermost edges of said front plate, said abutments being arranged perpendicular to each other, the distance between said interrupting means and said path of travel of the center of gravity of the bundles being arranged such as to cause said every other bundle to unobstructedly rotate substantially 90° during its movement between said interrupting means and said hopper.
