Abstract
A method and apparatus for compressing and packaging compressible materials. The compression is carried out continuously between parallel plates which come closer to each other as they advance. As the plates advance, the materials are accompanied by a lower packaging film and an upper packaging film which are joined at the sides of the compressed materials at the end of compression.
Claims17
Process for packaging a volume of compressible material, comprising:
- supporting a volume of compressible material on a pressing plate of a first carriage in a first train of carriages, there being a second train of carriages positioned above said first train of carriages such that a pressing plate of a second carriage of said second train of carriages extends parallel to said pressing plate of said first carriage and is positioned directly above said first carriage;
- moving said first and second trains of carriages in a horizontal conveying direction and at the same speed;
- and
- simultaneous with said moving step, drawing said pressing plates of said first and second carriages symmetrically toward one another in a pressing direction transverse to the conveying direction, while maintaining said pressing plates of said first and second carriages parallel to one another, so as to compress the volume of material between the plates of said first and second carriages.

Device for packaging a volume of compressible material, comprising:
- a first train of carriages having first carriages, each including a pressing plate for supporting a volume of compressible material;
- a second train of carriages having second carriages positioned above, and in correspondence with, the first carriages of said first train of carriages such that a pressing plate of each of said second carriages of said second train of carriages extends parallel to said pressing plate of a corresponding first carriage and is positioned directly above said pressing plate of said corresponding first carriage;
- a device for moving said first and second trains of carriages in a horizontal conveying direction and at the same speed;
- and
- a device for vertically drawing said pressing plates of said first and second carriages symmetrically toward one another in a pressing direction transverse to the conveying direction, simultaneous with said moving of the trains of carriages in the conveying direction, while maintaining said pressing plates of said first and second carriages parallel to one another, so as to compress the volume of material between the pressing plates of said first and second carriages.
