Abstract

Apparatus for cutting foam or the like products into predetermined patterns under electronic computer control and employing an apparatus that includes a frame, a table disposed in the frame and for receiving the product that is to be cut, and a carriage carrying at least one hot wire and preferably four hot wires. The carriage is disposed over the table and is suitably supported from the frame. There is provided associated with the carriage, both a first drive means for controllably driving the carriage in a first x direction and second means for controllably driving the carriage in a second Y direction. Control means are provided for controlling the first and second drive means to control product cutting along a predetermined path which in the disclosed embodiment is a diagonal path to provide final foam pieces cut in a pyramidal array configuration.

Dependent claims

Apparatus for cutting foam or the like products into predetermined patterns comprising;

a frame,
a table disposed at a lower position in the frame and having means for receiving the product that is to be cut,
means for driving the table only in one non-oscillatory horizontal direction in the frame and during a first cutting sequence,
a carriage carrying at least one hot wire disposed over the table and spaced from the table in a pre-cutting position of the carriage,
means for supporting the carriage from the frame,
drive mcans associated with the carriage for controllably driving the carriage only in one non-oscillatory vertical direction in the frame relative to the table and orthogonal to said direction of table drive and during a first cutting sequence,
and control means for controlling the carriage and table drive means to control product cutting along a predetermined diagonal path including means for providing simultaneous drive to both said carriage and table drive means at relative constant speeds that control the slope of the diagonal cut.
