Abstract
Abstract A method for compressing and cutting random loaded scrap metal comprises the steps of gravity advancing scrap metal to a cutting zone, applying a first transversal compression to the scrap metal being advanced, guillotine cutting a portion of the scrap metal and concurrently applying a further transversal compression. The machine comprises a scrap metal conveying trough, a transversally movable pressing plunger adapted for traversing the conveying trough and compacting the conveyed scrap metal, a guillotine block for cutting the compacted scrap metal and a guillotine driven compacting block movable perpendicularly to the pressing plunger and cooperating therewith.

Claim 1
Independent Claim
200 words
A method for continously compressing and cutting random scrap metal, comprising the steps of feeding random scrap metal continously by gravity to a guillotine cutting station in which the scrap metal is cut in a direction substantially perpendicular to the feeding direction of the srap metal, applying a first compression to the scrap metal in a region upstream of, and near to, said guillotine cutting station in a direction substantially transverse to the feeding direction of the scrap metal and substantially perpendicular to the cutting direction, applying a second compression to the scrap metal in a direction substantially perpendicular to the direction of said first compression and substantially parallel to said cutting direction upstream of, and near to, said guillotine cutting station and simultaneously cutting a portion of scrap metal previously compressed in said first and second compression step and advanced beyond said guillotine cutting station, wherein concurrently with said first compression step the scrap metal is gradually compressed upstream of said region of said first compression in the direction of said first compression such as to gradually gather the scrap metal toward said region, and wherein said first and second compression steps are carried out according to concurrent directions.
