US 5,311,799 A · Process and apparatus for cutting stacked sheet-like material in more than one direction with a single cutting knife

Abstract

A process and apparatus are provided for transferring material cut in transverse strips and located on an exit zone of an apparatus for the cutting of stacked sheet-like material, to an entry zone of the apparatus for the purpose of cutting such material into longitudinal strips. The apparatus has a cutting table with a table surface possessing a work zone, above which a cutting knife and a press bar are located. An advance device located in the entry zone is provided for the material to be cut. The material present in transverse strips is brought from the exit in zone onto a thin-walled, plate-shaped transport base. The transport base, together with the material, is fed, via at least one table which is arranged laterally of the apparatus and the table surface of which can be arranged level with that of the cutting table of the apparatus, to the entry zone of the apparatus and there, aligned with the entry zone, is removed from the transport base. The material to be cut is rotated out of the transverse direction into the longitudinal direction while being brought onto the transport base or together with the transport base or after removal from the transport base. The material to be cut is thus guided past the actual cutting device, and in the apparatus according to the invention, this purpose is served by arranging at least one table laterally of the cutting device.

Dependent claims

A process for cutting stacked sheet-like material in more than one direction with a single cutting knife, comprising:

pushing material to be cut from an entry zone of an apparatus toward said cutting knife located above a cutting table of said apparatus;
cutting said material in a first direction;
placing said cut material on a thin walled, plate-shaped transport base positioned on a first table part located proximate to an exit zone of said cutting table;
rotating said cut material prior to placing it on said transport base;
moving said transport base to said entry zone;
moving said cut material from said transport base onto said entry zone;
and
pushing said cut material from said entry zone toward said cutting knife to cut said material in a second direction that differs from the first direction in which the material is cut.

An apparatus for cutting stacked sheet-like material, comprising:

a cutting table having a table surface which comprises an entry zone for receiving material to be cut, a work zone proximate said entry zone where said material is cut, and an exit zone proximate said work zone for receiving the material after it is cut;
a gantry mounted above said work zone;
a single cutting knife mounted in said gantry;
an advance saddle located adjacent to said entry zone and operatively arranged to push material to be cut towards said cutting knife;
a transfer table located proximate said exit zone and also located proximate said entry zone;
and,
a transport base movable on said transfer table and operatively arranged to transport cut material from the exit zone back to the entry zone in order that said material may be re-cut in a direction which is different from a direction in which said material is first cut.
